INTRODUCTION 



This document is the transcription of the technical air-to-gromd 
(TAG) voice commimi cat ions of the Apollo 15 mission. The transcript is 
divided into three columns — time, speaker, and text. The time column 
consists of four two-digit pairs for days, hours, minutes, and seconds 
(e.g., ok 22 k5 12). The speaker column indicates the source of a 
transmission; the text column contains the verbatim transcript of the 
communications . 

The time used by Mission Control Center (MCC) and indicated as 
ground-elapsed time (GET) in the flight plan may be updated to both the 
spacecraft and MCC computers but will not be updated to the telemetry 
downlink pulse- code-modulated bitstream or other time-recording devices. 
This GET updating will be performed only to correct significant changes 
in the flight-plan time occurring as the result of delayed lift-off, 
midcourse corrections, or spacecraft burn-time differences (trajectory 
dispersions ) , 

Should these updates occur, the Apollo elapsed time (the true 
mission-elapsed time) may not agree with flight-plan and MCC times. 
Users of this transcript are cautioned to apply the appropriate time- 
update deltas for the updated periods. 

Communications recorded from the primary communications network 
(GOSS net l) comprise the bulk of this transcript. During periods when 
the lunar module (LM) and command module (CM) are physically separated, 
it is occasionally required that communications with both spacecraft be 
available simultaneously. To accomplish this, another communications 
network (GOSS net 2) is activated. At such times, this transcript will 
include the simultaneous but separate communications. To indicate the 
period of GOSS net 2 usage , a heavy dark line will be used alongside the 
time colijmn. 

A series of three dots (...) is used to designate those portions of 
the text that could not be transcribed because of garbling. A series of 
three asterisks (***) is used to designate those portions of the text 
that could not be transcribed because of clipping caused by the voice- 
actuated (vox) mode. One dash (-) is used to indicate a speaker's pause 
or a self-interruption ajid subsequent completion of a thought. Two 
dashes (- -) are used to indicate an interruption by another speaker or 
the point at which a recording was abruptly terminated. Words given 
unusual emphasis by the speaker are underlined.

The Apollo 15 mission was flown July 26 to August 7, 1971; lift-off 
occurred at 13:3i+:00.79 G.m.t. (9:3lt:00.79 a.m. e.d.t.) on July 26.

When the CDR and IMP are in the undocked Iwiar module or on the 
limar surface, their speaker designations will be suffixed by either IK 
or EVA to indicate their status (e.g., CDR-EVA or LMP-LM) . Voice calls 
during this mission were assigned in accordance with the following 
station operating procedures: "For all phases when only the CSM is 
manned, the AS-510 call sign will be Apollo 15. When both vehicles are 
manned, the voice call will be Endeavor for the CSM and Falcon for the 
LM. The calls for the CDR and IMP during lunar surface operations will 
be the individual crew's first names." 

Transcription of these tapes was managed by David M. Goldenbaum, 
Test Division, Apollo Spacecraft Program Office, to whom inquiries 
regarding this document should be referred. 

ACRONYM LIST 



Because specialized readers of the Apollo 15 transcription, such 
as the principal investigators, may not be thoroughly familiar with 
the acronyms used during the mission, the decision was made to define 
those acronyms that probably will be encountered. For obvious reasons , 
no effort was made to include every acronym that conceivably could be 



used; only those acronyms that are considered likely to be used are 
included here.

let's go ahead and tiy it. 

00 05 55 CC Okay. Stand by; I'll get everybody watching. Okay. 

First of all, I'd like to he sure that both the 
PILOT VALVE circuit breakers on panel 8 and both 
DELTA-V THRUST switches are OFF - both circuit 
breakers . 

00 05 56 OU CMP Okay, Houston. Both PILOT VALVES are open, and 

the DELTA-V thrust switches are OFF. 

00 05 56 10 CC Okay. Now when we do the following steps, we'd 

like you to watch the SPS THRUST light, and watch 
it for changes either going out or changes in in- 
tensity. We're trying to determine if it's a high- 
resistance or a low-resistance short, and if it 
gets brighter, that'll tell us something about this 
short with any one of these actions.

EMS DELTA-V check - from page G/2-5 and Just the 
first steps - down to the - don't have to do the 
bias check, but the first six steps there. 

00 05 58 11 CMP Right. 

00 05 58 22 CC Idea here is to check for a possible short in the 

DELTA-V test circuits. It might be causing the 
light on. 

00 05 58 1+5 CMP Okay, Gordo. That part of the check's been run 

and shut off at a minus 21.4 in 10 seconds, and 
the SPS light - the SPS THRUST light got distinctly 
brighter during the decelerat - or diiring the ac- 
celeration period.

00 07 35 10 CC Hey, the results that we got out of that last test 

procedure - didn't solve many prohlms for us. I 
guess the best we found out was that we don't have 
a simple problem like a stuck EMS relay. And 
there's a lot of thinking going on down here, and 
at the present time, we line up three - three 
possibilities, depending on where the ground is in 
the system. And the first one is that it's still 
a ground that simply turns on the light and affects 
nothing else. Second possibility, that it's a 
ground that's going to light the engine early when 
you put on the DELTA-V THRUST switches. And there's 
a third possibility, that the - the ground is 
upstream of the pilot valves, and that we'll bro - 
we'll blow the PILOT VALVE circuit breakers and 
lose that bank, if - If we're unlucky. We're 
busy down here working on a procedure that we could 
use at midcourse correction 1 to decide which - 
which of these three possibilities is the right 
one. And we're talking about getting this all 
worked out and sent up to you in about 2 hours. 

00 07 35 28 CDR Okay; understand. Good luck.

00 09 22 k2 CC Roger. On page 3-15 In the Flight Plan, in the

frames with filter number 2. 

00 09 22 58 CMP I found that line. 

00 09 23 00 CC Roger. And instead of two frames at 20 seconds, 

we would like one frame at 20 seconds; and we would 
like a second frame at 2 seconds. 

00 09 23 21 CMP Roger. I copy one at 20 seconds and one at 

2 seconds. 

00 09 23 31 CC Roger, The reason for that is that they have recently - 

measured a secondary light leak in that filter, and they 
need a - two different exposures like this to really 
separate the two peaks in the filter transmissivity .

might be able to do it while Al works with the P23. 

00 09 26 1+8 IMP Okay; go ahead. 

00 09 26 53 CC You might refer, if you want to see what's going 

on, to drawing 8.9 down in area E-3. We're 
playing with the - DELTA-V THRUST switch, and the 
idea is this. First of all, let's open the - the 
GROUP 5 circuit breakers on panel 229, both t4AIN A 
and MAIN B. That's a backup to the SPS PILOT 
VALVES on PAITEL 8, which we also want open. 
Verify that. 

00 09 27 25 LMP Okay. GROUP 5, MAIN A and MAIN B on 229. Stand 

by. 

00 09 27 33 LMP Both are open. 

00 09 27 35 CC Roger. We've verified GROUP 5, both open; and the 

SPS PILOT VALVES, both open. Then, we'd like to 
take the DELTA-V THRUST A switch and try to balance 
it right in a center position. Tease it back and 
forth a little bit - to see if you can get any 
flickering in the SPS THRUST - THRUST-ON light. 

00 09 27 58 LMP Okay. Stand by. 

00 09 28 05 CC Jim - Let's - let's hold up a little bit before 

we do that. We don't - We're not all set up down

here to watch that also. So let's - let's read on 
through the procedure. 

00 09 28 15 LMP Okeydoke. 

00 09 28 l6 CC If the light does flicker, of course, that's going 

to isolate, in this case, if we were playing with - 
with the DELTA-V THRUST A switch. That'll isolate 
the problem into the - to the A bank of valves. 
If we don't see any flicker, then we'll go ahead 
and try it with the - with the B bank. Actually, we 
woixLd like to go ahead and do it with the B bank 
also. So, stand by. 

00 09 28 hi LMP Okay. I understand. Standing by.

00 09 29 01 LMP HIGH GAIN, MEDIUM. 

00 09 30 hi CC 15, this is Houston. We're ready to go ahead. 

Verify again the GROUP 5 breakers and the SPS 
PILOT VALVE breakers, and then let's tease that 
DELTA-V THRUST A switch. Try to balance it in 
the central position. 

00 09 30 56 LMP Okay. Will do. We - we note that trying 8.9 Echo 3 

doesn't seem to ... what you're doing. 

00 09 31 17 CC Actually, it's area Echo 3 and U, and it simply 

shows you the DELTA-V THRUST switches there. 

00 09 31 2h LMP Oh, okay. Okay. 

00 09 31 27 CC The light has a contact, whether that switch is 

on or OFF, and we would like to balance it halfway 
between, so that we don't have a contact. 

GO 09 31 36 IJyIP Okay. Here goes DELTA-V A now. Okay A is up and 

on, and the SPS THRUST light is off. 

00 09 32 00 CC Would you confirm that the DELTA-V THRUST A switch 

is up and the light went out. Is that correct? 

00 09 32 06 LMP That's correct. It's still in the up and on 

position, and when I went to the on position, the 
light went out.

THRUST - A back to OFF. 

00 09 35 01 IMP A is OFF, and the light remains off. 

00 09 35 07 CC We copy. 

00 09 35 39 CC 15, this is Houston. Our telemetry confirms both 

of your observations, and we would now like to have 
you cycle Bravo. 

00 09 35 1+7 liMP Roger. Bravo is up and on; the light is off. Now 

Bravo is OFF, and the light remains off. 

00 09 36 00 CC We copy, 

00 09 36 li5 CC 15, we'll sit tight and think about that for a 

while. Thank you. 

00 09 36 50 LMP Roger. 

00 09 1+1+ 21 CC 15, this is Houston. As a final check as to what's 

happening in that switch, we'd like to have you 
tap around the DELTA-V THRUST switches a bit. See 
if any light flickering comes on. 

00 09 hk 33 LMP Roger. In work. Would you believe, it came on! 

00 09 1+1+ 1+1+ CC We copy, and we saw it down here. Okay. With the 

light on now. Let's cycle Bravo on and try to 
tease it in the middle if it stays on. 

00 09 1+5 02 LMP Okay. Cycling Bravo. 

00 09 U5 16 LMP Okay. No change at all with the Bravo on, cycling 

several times through the middle. 

00 09 1+5 20 CC We copy. Okay. Leave Bravo OFF, and let's cycle 

A again,

00 09 h'j hi LW Okay. Right in the center of - the contacts with 

A, right between the two, I can get the lif^ht to 
go out. But now, when I go on up - up and on, the 
light comes on again. And now, I've come back to 
the OFF position, and the light's off. So, I think 
you've isolated yom- problem. 

00 09 59 CC Roger. 

00 09 1*8 UT CC 1?, this is Houston. We're willing to stop 

playing with the - with the light problem at the 
present time. We'd like to verify that both 
DELTA-V THRUST switches are OFF. And we'd like 
to have the GROUP 5 circiiit breakers both closed, 
but please keep the PILOT VALVE circuit breakers 
open. 

00 09 h9 05 CDR Okay. DELTA-V THRUST verified OFF. PILOT VALVES 

verified open, and we'll close the GROUP 5. 

00 09 h9 15 CC Thank you. 

00 09 57 17 CDR OMNI Delta, please. 

00 09 57 20 CC Roger. OMNI Delta. 

00 09 57 1|8 CC 15, this is Houston. 

00 09 57 52 SC 15. 

00 09 57 5^ CC Let's - summarize our situation with that - with 

that THRUST OU light. The telemetry we got down 
here - we actually have two lights which show up in 
in that area, E-H and 5 on diagram 8.9 - gave us 
some rather confusing data that we don't understand 
yet, but we'll be working on it. But we - we do 
feel confident enough that there's no need to fire 
the engine at the present time, and since the 
midcourse 1 is a correction of 2,8 feet per second, 
we don't think that we'll be having a midcourse 1, 
For your information, at the present time, mid- 
course 2 looks about like 5.0 feet per second. 

00 09 58 h2 CDR Okay; understand. We'll just hold tight; skip 

midcourse 1; stand by for 2. 

00 09 58 hi CC Roger. And, 15, be advised we'll have a Flight 

Plan update in the near future.

we can finish a battery charge that's in progress. 
And, also, that waste water dump; be sure to - 
to do the water dunip before you start PTC.

00 Ik 32 kk cm Okay, Houston, 15. We're ready for the E-memory 

dump for you, if you're ready. 

00 Ik 32 53 CC Okay, 15. We're ready to go with it. 

00 lit 32 58 CDR Okay, here it comes. 

00 ll+ 33 52 CDR And, Houston, 15 . We've got the rest of the pre- 

sleep checklist if you're ready to copy. 

00 11+ 3k OT CC Roger, 15. We're ready to copy. 

00 11+ 31+ 12 CDR Okay. Crew status report: everybody's in good 

shape; no medication today. Onboard read-outs- 
BAT C, 37.0; PYRO BAT A, 37.2; PYRO BAT B, 37.2- 
RCS A, 9ki B, 92; C, 9k; D, 9k. And the water has 
been chlorinated; the fans have been cycled; 

the valves are all verified; got your E-memory 
dvanp. The cabin is at 5-7; DIRECT 0^ is closed, 

and I guess we're ready to go to sleep communica- 
tions configuration. 

00 Ik 35 23 CC Roger, 15. We copy all of that, and the Surgeon 

has a question about - were there - were there any 
obvious anomalies in the biomed harness? 

00 1^ 35 31+ CDR No, as a matter of fact, we were just discussing 

that. Al and I both have taken them off, and the 
sponges are all still quite damp and have their 
color and they're all sticking very well. I 
think the system looks real good.

01 01 31 hi CC Okay, Jim. Coiild you stand by on that? We'd just 

as leave you not do it right at the moment. 

01 01 31 h9 IMF Okay. We'll stand by. 

01 01 31 50 CC Roger. And we'll give you the word when we're 

ready for that. 

01 01 31 56 LMP I'll get the radiation report here shortly, and 

- could you confirm by position that - FAN 
should be in? 

01 01 32 08 CC Roger, Jim. And, it - the H FAN 3 should be 

AUTO. 

01 01 32 19 LMP Roger. I copy AUTO. 

01 01 32 21 CC Roger. 

01 01 3U 25 CC Jim, this is Houston. 

01 01 31+ 30 LMP Go ahead, Joe. 

01 01 3h 36 LMP Go ahead, Joe. 

01 01 3^+ 37 CC Roger, Jim. Just for your own information here, 

let me read up to you the GSM consumables that 
we've generated from the ground. 

01 01 3h kg IMF Okay. 

01 01 3h 5U CC Okay. At GET 25:09, we had RCS total, 90; quad A, 

89, 91, 89, 91. tank 1, 9^ percent, 92 percent, 

81 percent. 0^ tank 1, 91 percent, 92 percent, 

97 percent. So it agrees pretty well with - what 
you guys are reading. 

01 01 35 ^1 LMP Good. Except for the - the RCS quantity. 

01 01 35 ^5 CC Roger. 

01 01 35 53 LMP Okay, Joe. The IM/CM DELTA-P is a plus .7-

01 01 37 51 IMP Go ahead, Joe. 

01 01 37 53 CC Jim. Are all three people still there? 

01 01 38 01 IMP All here are busy doing little things. 

01 01 38 0l+ CC Okay, good. I've got some information for you 

when - you reach a minute - you - you want to 
listen here, and it concerns our - short - 
little short problem in the switch. 

01 01 38 26 LMP Okay, Joe. We're all listening. Go ahead. 

01 01 38 29 CC Roger, guys. We're going to ask you to do a - a 

test "burn on your SPS a little later , in fact , 
around 28 and 1/2 hours. And - depending upon 
the results of that, we'll go ahead and do the 
midcourse, and it will be a normal midcourse if 
the burn test doesn't really come off. And it'll 
be a trim midcourse of some kind if - the test , 
in fact, does give us an SPS burn. And I'll come 
up to you a little later on in the day with a set 
of procedures. There - a long list of them, but 
you'll be able to use your Launch Checklist for 
most of them. However, the test burn will mean 
that we're going to change - we're going to update 
your Flight Plan - with a - a large number of 
things a little later on. About 10 minutes, I'll 
be reading that to you. Is it clear so far? 
Over. 

01 01 39 31 CDR Yes. That's fine. Joe. Can you give us a little 

rundown on what you think the problem is? 

01 01 39 37 CC Dave, when we get the better OMNI in a second, I'll 

start talking about that. We're about to lose the 
comm. 

01 01 39 CDR Okay. 

01 01 h3 hi CC Endeavour, this is Houston. 

01 01 h3 h6 IMP Go ahead, Houston. 



Tape YJ/h 
Page 56 



01 01 U3 hd> CC Roger, guys. First of all, Dick Gordon is over 

in the simulator right now running through this 
SPS burn procediire, and as soon as he says that's 
okay, we'll read that procedure up to you; I 
guess. It's not too complicated. Dave, in regard 
to your last question, very briefly — and I'm 
sure you guys have been thinking a bit about this 
yourselves — we're interested in finding out 
exactly where in your DELTA-V THRUST A switch the 
short seems to be. And we're - all of us down 
here are convinced that it's either in that switch 
or physically very near that switch. It's important 
that - that we know where it is, because - I guess 
the - the worst that it could be - would be a hard 
short — so-called hard short — upstream of the 
control PILOT VALVE solenoid on bank A. And 
that would mean that we would lose the ability 
to turn bank A on and off as we wanted to. 
There are many other things it could be; namely, 
a soft short either upstream or downstream from 
that PILOT VALVE solenoid. Or I guess it could 
be a hard short downstream from the solenoid, 
which - ail of these would be annoying to us, 
but no major problem, really. It - - 

01 01 U5 17 CDR Okay. We get the general 

01 01 1+5 20 CC Go ahead, Dave. 

01 01 U5 20 CDR We get the general - yes, we get the general gist 

of that, Joe, Go ahead. 

01 01 1+5 28 CC Okay, Dave. What - what we're going to try to do 

now is to go - go ahead and do an SPS burn using 
bank A. And we want that short to be active when 
we do it. So at some point, we're going to ask 
you to tap on the panel and try to get the short 
back for us. We - we show that the light is 
currently out, and I'm sure you'll confirm that. 

01 01 i+5 52 CDR That - that's verified. 

01 01 ^5 53 CC Roger. Assuming we cannot get the light on again 

— we think that is unlikely — "^ut , if we can't 
get it on again, we'll delete this particular 
test and just go ahead and do a midcourse - 
normal midcourse 2 burn - and while we scratch 
our heads on this other thing.

01 01 k6 Ik CDR Okay. 

01 01 h6 18 CC Now. Dave. We've got the changes to the Flight 

Plan here if your recording secretary is standing 
"by to copy it . 

01 01 k6 30 CDR Okay. Go ahead. I'm ready, Joe. 

01 01 k6 36 CC Roger, Dave. Are you just going to mark up the 

Flight Plan as I read It to you? 

01 01 k6 hi CDR I'd prefer to do it that way. 

01 01 U6 hh CC Roger. We think that'll he the easiest. And, 

Jim, are you copying this now? 

01 01 U6 h9 IMP I'm standing by, Joe. 

01 01 U6 51 CC Roger. Okay. Okay. We're going to start at 

25:05s and we've already deleted the charge- BAT- 
A line. Then moving on to 26:50, add P52 IMU 
realine, option 3. Moving to 27 - - 

01 01 hi 30 LMP I copy. 

01 01 kf 31 CC Okay. Moving to 27:55- Move DELTA-V test and 

null hias check up to 27 : 00 . In other words , 
just move that line up. And coming up to 28:00 
— a little something for you, Al — we're going 
to delete the crew exercise period. And at 28:00, 
add in midcourse column - MCC-Houston colimn - 
uplink to CSM, CSM state vector and VERB 66; 
update to CSM SPS test maneuver pad. And at 
28:05, PURGE LINE HEATERS, on-, exit G&W PTC,- 

and maneuver to pad hurn attitude. Have you 
copied so far? 

01 01 kg 26 LMP Yes, I copied everything to The MCC-H column. 

Understand the PURGE LINE HEATER, on; and 

exit PTC; and maneuver to pad burn attitude at 
28:05. 

01 01 ^9 36 CC Roger, Jim. And we're going to lose comm. in a 

minute; I'll be back with you. 

01 01 U9 k2 IMP Okay.

01 01 52 00 CC Okay, Jim; this is Houston. The comm's back again. 

How do you read me? 

01 01 52 06 IMP Loud and clear. 

01 01 52 08 CC Okay, I'm ready to continue. And we'll pick up at 

28:15, with a sextant star check. 

01 01 52 29 LMP Okay. 

01 01 52 30 CC Okay; 28:20 I'm - going - going to read to you 

seven lines of instructions here, and they're 
all reproduced two pages over in your Flight Plan 
at 30:30. Your choice as to whether you want to 
copy them or Just look two pages ahead. I'll go 
ahead and read the lines now. 

01 01 52 5T MP Why don't we just look two pages ahead? 

01 01 52 59 CC Okay. 

01 01 53 00 IMP Go ahead. 

01 01 53 01 CC Okay. We're going - I - I want you to move seven 

of the lines from 30:30 to 28:20. And those seven 
lines are: the SM SECTOR 1 SM/AC POWER, on; PAN 
CAMERA POWER, BOOST; MAP CAMERA IMAGE MOTION, OFF; 
MAP CAMERA, ON, STANDBY; and 0^ fuel cell purge; 

waste water dump; and, at 28:35, H^ PURGE LINE 

HEATERS, OFF. 

01 01 5^ 02 LMP Okay, I'll ... the six steps there 

01 01 5^ 05 CC Okay. 

01 01 5^ 06 mP at 28:20. 

01 01 5it 09 CC Roger, Jim. That's right. And the seventh step 

was at 28:35; you're correct, and that brings us 
to 28:1+0, which is SPS burn test. And at 2Q:kl, 
VERB 66, set CSM state vector into LM state vector. 



01 01 5^+ 52 LMP 



Okay. Copied SPS burn pad, VERB 66.

01 01 5^ 55 CG Roger. 30:13, delete, and in fact, all the other 

items from here on out are deletes. And I'll go 
through than quickly. 30:13, delete battery charge 
A termination; 30:15, delete PURGE LINE HEATERS, 

ON; 30:18, delete exit G&K PTC; 30:23, delete - 
if SPS MCC required and the references to pan and 
mapping cameras - the things, in fact, that you 
moved ahead; 30:35, delete and 0^ fuel cell 

purge and waste vater dump; and, finally, 30:50, 
delete PURGE LINE HEATERS, OFF. Over. 

01 01 56 15 IMP Okay. I copied all that, Joe. 

01 01 5T 1^ CC Okay, guys. That's all we've got for you for the 

moment. Dick walked into the MOCR a few minutes 
ago. He says that the test burn procedure went 
okay. We're going to look it over one last time 
and then read the procedures to you. 

01 01 57 29 LMP Okay. 

01 02 oh 03 CDR Houston, this is 15- We're ready to cycle the film 

in the - the pan and mapping cameras. 

01 02 oh 22 CC Endeavour, we're ready when we get the HIGH GAIN 

going here. And I guess we'll have that ready 
about 5 minutes . 

01 02 Oh 33 CDR Okay. 

01 02 05 05 CC Endeavour, this Is Houstion with your HIGH GAIN 

ANTENNA angles; update.

01 02 06 15 CC Jim, if you'll go ahead and set the angles in, 

we'll give you the cue when we're ready for you 
to select the high gain. 

01 02 06 25 LMP Okay. 

01 02 06 26 CC And it looks like it will he about 10 minutes, I 

guess . 

01 02 06 32 LMP Roger. 

01 02 08 22 CC Endeavour, this is Houston. 

01 02 08 27 LMP Go ahead. 

01 02 08 28 CC Roger, guys. Wondered if you were interested in 

any breakfast-time news up there? 

01 02 08 36 LMP Yes, sir; we always are. 

01 02 08 39 CC Is it breakfast time? 

01 02 08 k2 LMP Yes, it's just about. 

01 02 08 52 CC Okay, Troops. Let me start with a special message 

of Godspeed to the crew of Apollo 15 from President 
Richard Hixon. And I'll quote directly from him, 
and there &rs some words in here that are very 
well expressed, I think. "Apollo 15 is safely on 
its way to the Moon, and man is on his way to 
another step across the threshold of the heavens. 
Man has always viewed the heavens with humility, 
but he has viewed them as well with curiosity 
and with courage; and these defied natural law, 
drawing man beyond gravity, beyond his fears, 
and into his dreams, and on to his destiny." 
And we may be losing comm here. Let me stand 
by for a minute. 

01 02 10 kQ CC Endeavour, select the HIGH GAIN for us, please. 

01 02 10 59 CC Okay, guys; suddenly you're back loud and clear. 

How do you read, Houston? 

01 02 11 11 LMP Okay, we're ... 

01 02 11 1+1 CC Endeavour, this is Houston. How do you read? 



Tape lT/9 
Page 61 



01 02 12 04 CC Apollo 15, this is Houston. Over. 

01 02 13 02 CC Hello, Endeavour, this is Houston. Over. 

01 02 13 07 liMP Go ahead. 

01 02 13 08 CC Roger, Jim. Sorry for the inter - interruption 

there. We had severe noise on our comm momentarily, 
hut it's cleared up now. I'll go ahead with the 
morning's news and a quote from President Nixon. 
"The flight of Apollo 15 is the most ambitious 
exploration yet undertaken in space. Even as it 
reflects man's restless quest for his future, so 
it also reenacts another of the deeper rituals 
of his bones, not only the compulsion of the 
inner spirit to know where we are going , but the 
primal need in man's blood to know from what we 
have come. We hope, by this Journey, to know 
better the origins of Earth, the Moon, and other 
planets. We hope to understand something more 
of the mysteries of God's great work. And, in 
this seeking, we hope to understand more of man 
himself. To the men of Apollo 15, for all men, 
I say. Godspeed." End quote. And there's a 
second message here that was telephoned to 
Dr. Fletcher yesterday through the State Department. 
It reads, "Congratulations on flawless launch. 
Please pass my best wishes for a successful 
mission to the crew of Apollo 15 and to your 
entire staff." And that message is signed 
Spiro T. Agnew. And a third comment about the 
launch was the launch is called flawless and 
you three are described as being very businesslike. 
And Kappy is quoted as saying, quote, "The mission 
was the most nominal launch we have ever had." 
Unquote. And I'd like to put in an editor's note 
here. That's probably technically correct, but 
it's aesthetically very incorrect. You could 
track the vehicle for hundreds of miles, literally 
hundreds of miles through beautiful clear sky, and 
it was a sensational launch aesthetically. I 
suspect you - I'm sure you will agree with that. 
Let's see, we've got an item here on Muhaimnad Ali- 
Jimmy Ellis fight here in the Astrodome, and it 
was declared a technical knockout in favor of 
Muhammad Ali in the last round - the 12th round. 
And it says that Ali took control of the fight in 
the 6th round and signaled the start of the end 
with an uppercut midway through the final round. 
And continuing on with the news, if you're still 
reading. Western Union employees - - 



Tape 17/10 
Page 62 



01 02 15 59 CDR Roger, Joe. 

01 02 16 00 CC Okay, Western Union Employees have announced 

agreement on a new contract that will end a 
nationwide walkout that hegan June 1. The 17,000 
striking workers wl2.1 go back on the Job Wednesday 
morning. The Lockheed Company lost two Senate 
vote - votes today in its attempt to avoid bank- 
ruptcy by obtaining a $250,000,000 Government 
loan guarantee. In sporting news or further 
sporting news, the Oilers traded Jerry LeVias 
to the San Diego Chargers in exchange for two 
linemen, defensive lineman Ron Billingsley and 
the 300-pound Gene Ferguson. The Oilers will use 
Ferguson at offensive tackle, it says. And, 
finally, the Minnesota - Minnesota Vikings lost 
the services of starting guard Jim Vellone when 
the doctors revealed that - that an undisclosed 
ailment would require long-term extensive treat- 
ment. And that's the end of the condensed news 
page I have in front of me this morning. 

01 02 17 1^ CDR Okay. Thank you very much, Joe, and please 

express our appreciation to the President and the 
Vice-President . 

01 02 17 21 CC Roger. Sure will. 

01 02 17 h6 CC Endeavour, Houston. Go to AUTO TRACK for us now, 

please, and we're going to wait for another REV 
before we start to cycle those cameras. 

01 02 18 00 CDR Okay, Joe. AUTO TRACK.

Endeavour, this is Houston. We'll be coming up on 
your camera cycling in about 15 minutes. It's for 
your own planning, and we'll cue you when we're 
ready for that . 

Roger. We read, Joe. 

Endeavotir , could you select your REACQ mode now for 
us, please? 

Okay. Going to REACQ. 

Roger. 

Okay, Endeavour; this is Houston. And we're ready 
for the camera cycling procedure now. 

Stand by, Joe. 

Roger . 

15 J this is Houston. If we're going to complete 
the camera cycling on this rev, I guess we'd better 
get started on that . 

Yes, we're in the process, Joe. 

Okay. 

Houston, 15. 
Go ahead. 

Okay; if you're reading all this on good telemetry 
down there, Joe, we'll go ahead and cycle this 
thing. 

Roger, Al. Go ahead. But stsind - stand by. Sorry; 
stand by. 

Okay. 

We're not getting high bit rate data yet.

01 02 38 03 CC Al, this is Houston. Is your data system switch 



on 



01 02 38 12 CMP Roger, Joe. That's affirm; It is. 

01 02 38 15 CC Roger. 

01 02 h3 20 CC Apollo 15, Houston. 

01 02 k3 27 CMP Go ahead, Houston. 

01 02 1+3 28 CC Guys, we're having trouble picking up the proper 

data so we can monitor the film cycling process 
here. So we're going to have you stand by on that 
until o\ir next high gain acquisition, and we'll be 
back with you. In the meantime, leave all the SIM 
bay in the present configuration, if you would, 
please . 

01 02 k3 50 CMP Roger. 
01 02 1+3 53 CC Okay - - 

01 02 1+3 5lt CMP Is there anything we can do to help, Joe? 

01 02 1+3 56 CC Say again, Al. 

01 02 1+3 59 CMP Is there anything we can do to help? 

01 02 1+1+ 37 CC Al, this is Houston. We don't think there's any- 

thing that - that you can do to help us at the 
moment . 

01 02 1+1+ 52 CMP Roger, Joe. 

01 02 1+1+ 5I+ CC Okay; and in the meantime, we'd like to talk about 

upcoming SPS burn, and we're going to be reading 
procedures up to you In a moment, and we think 
it's the easiest for you to copy these into your 
CSM Launch Checklist. So you might be looking for 
that and - and getting that out. 

01 02 1+5 2I+ CDR Okay, Houston, I wonder if you could hold off for 

about 10 or 15 minutes, and let us get through the 
breakfast chores here, and then we can settle down 
and c one entr at e .

for us, OFF, and then, on, please. 

01 03 05 33 CMP Okay, Jose; do it. 

01 03 05 36 CC Okay; and the problem here, we're seeing all the 

carriers, but we don't get proper modulation, and 
so we're Just not getting the right data.

01 03 11 09 CMP Houston, 15; go ahead. 

01 03 11 11 CC Roger, guys. The attitude which you're currently 

holding is a good attitude for your P52, if one of 
you wants to get started on that. We'll have some 
words for you on the SIM bay problem in a few min- 
utes, and then we'll want to be talking about the 
SPS burn coming up pretty shortly here. That is, 
we want to talk about it shortly; it won't be 
coming up for a while. 

01 03 11 kl CMP Okay, Joe; I'll start doing the P52.

01 03 12 51 CC Al, your choice here. We suddenly found the 

missing data. It mysteriously reappeared, and 
we - we're ready to go ahead with your film 
cycling procedure. Your choice if you want to do 
your P52 first or the film cycle first, and we're 
standing by for either. 

01 03 13 07 CMP We're all set up on the - we're all set up on the 

film cycle, Joe. Why don't we go ahead and do 
that, and then I'll flip down and do P52,

01 03 25 ih cm Go ahead, Joe. 

01 03 25 15 CC Guys, we Just had indication that your THRUST light 

came on again for about 10 seconds. Did you notice 
that? 

01 03 25 23 CDR Yes. Roger, Joe. That was the EMS DELTA-V check. 

01 03 25 28 CC Okay, Dave. Thank you. And, guys, we - we'd like 

to ask that you locate your CSM Launch Checklist, 
because we want to start talking about this SPS 
burn procedure. 

01 03 25 kh CDR Okay, we'll be ready in a couple minutes. 

01 03 27 29 CDR Okay, Houston. We've got the Checklist out, and 

we're ready to listen. 

01 03 27 35 CC Okay, Dave. If you would, please, turn to page L/k- 

lU , and we're Just going to ask you to copy the pro- 
cedure onto that page, because it will consist of 
just a few changes to what's already listed on - 
on those few pages there. 



Tape 18/6 
Page 68 

01 03 27 59 CDR Okay; we've got L/U-lU. Go ahead. 

01 03 28 05 CDR We've got L/U-lU. Go ahead. 

01 03 28 09 CC Okay. Unless you'd like an explanation of what's 

to come, I'll go ahead and read through the steps 
here and pause from time to time to make sure 
that you're getting it all, and then we can talk 
about the details of why it's "breaking out like 
this when we finish it. 

01 03 28 27 CDR Okay. Go. 

01 03 28 29 CC Roger. I'm going to start there at the line, "If 

time permits, go to G&N thrusting procedures," 
et cetera, and right underneath that short para- 
graph, write in: "Circuit breakers EPS GROUP 5, 
two, close;" and that's a "Verify." 

01 03 28 57 CDR Okay, circuit breakers EPS GROUP 5, two, close. 

That's the main A and main B, right? 

01 03 29 02 CC Yes, sir. And then we'll go on down about four 

lines to the "Set DELTA-V" and that should read: 
"Set DELTA-V^ minus 100." 

01 03 29 18 CDR Roger. Set DELTA-V„ minus 100. 

01 03 29 21 CC Roger. Now into the TVC check and prep section. 

After the first line, which is "Circuit breaker 
STAB control system, all, close," insert "Circuit 
breakers SPS pilot valves, two, open" and that's 
a "Verify." 

01 03 29 i*5 CDR Okay. Circuit - okay; circuit breaker SPS pilot 

valves, two, open, verify. Below the line it has 
"CB stability control system, all, close." 

01 03 29 59 CC That's correct, Dave. And the next line shoxild 

read "Circuit breakers SPS, 10, close." 

01 03 30 09 CDR Okay, understand. Circuit breakers SPS, 10, 

closed. 

01 03 30 12 CC Roger. Skipping down several lines; DELTA-V CG, 

LM/CSM. 

01 03 30 2I+ CDR Roger. DELTA-V CG, LM/CSM. 



Tape 18/7 
Page 69 



01 03 30 3^+ CC Okay, Dave. Turn to page . And your next 

01 03 30 ^1 CDR - - I+-15, 

01 03 30 h2 CC Roger. And your next change is in the TVC check, 

third line from the bottom of that first group 
there; delete "Rate, high." 

01 03 30 59 CDR Okay; secondary TVC check, third line from the 

hottom; delete "Rate, high." That's the line 
right after "Limit cycle, off." 

01 03 31 07 CC That's correct. Down into the next group, "DELTA-V 

THRUST A to NORMAL." You can 

01 03 31 19 CDR "DELTA-V THRUST A to NORMAL," and delete "B." 

01 03 31 23 CC That's affirm, and then insert right after that - 

immediately after that, the following note. "Get 
thrust light on by pushing on panel first." 

01 03 31 CDR Okay. In other words, you want us to try and get 

the SPS thrust - thrust light on by tapping on the 
panel some way, so that the light is on with the 
DELTA-V thrust A switch up to normal. Is that 
right? 

01 03 32 00 CC Dave, that's not quite right. Let me read through 

it. We want you to get the light on, but we want 
you to try to first get it on just by pushing, by 
flexing the panel around the switch in question. 
And the reason we're doing that, we think - it's - 
The probable short is contamination in the switch, 
but there ' s a small chance that it ' s some sort of 
a problem in the wire bundle that will be flexed 
very slightly when you just push on the panel. 
So that - the note should read the following, and 
I'll read it clear through to the end. "Get thrust 
light on by pushing on panel first. If this 
doesn't work, rap on panel or cycle the switch un- 
til the light comes on. And if the light doesn't 
come on, we're going to delete the test." 

01 03 32 57 CDR Okay. Why don't we try that right now? 

01 03 33 03 CC Dave, stand by a second. 

01 03 33 07 CDR Okay. 



Tape 18/8 
Page 70 

01 03 33 IT CC Dave, let's - let's ask you to stand by on that. 

We'd prefer to complete reading the procedures to 
you, and then - we'll worry about this light busi- 
ness. At any rate, you should have inserted the 
note "Get thrust light on by pushing on panel first. 
If this doesn't work, rap on panel or cycle the 
switch and if no light, then delete the test." 

01 03 33 ^5 CDR Okay, understand. Push, rap, cycle, and if no 

light, delete the test. 

01 03 33 50 CC Beautiful. Okay. Now, at about 1 minute to go 

but definitely after the light is on, proceed on 
to the next step, which is VERB 37 ENTER, U7 ENTER. 

01 03 3h 10 CDR Okay. If we get the light on, then we're at 2 min- 

utes, and we'll work for about a minute to try to 
get the light on. And if we don't get it on by 
1 minute, then we'll consider that we cannot get 
it on, and if we do get it on by 1 minute, we'll 
call up Pl;7. 

01 03 3^ 29 CC Dave, it's - I guess that the 2-minute mark out 

to the side of your Checklist there is meaningless 
in this case, because the test is in no way time 
critical. We want you to take yoiur own time and 
work to get the light on, but if it does come on 
at about 1 minute before the burn , we ' 11 want you 
to go into PROGRAM kj . 

01 03 3^ 53 CDR Okay, I'm with you. Just to make siore we have 

Pi+7 running. 

01 03 3^+ 57 CC Roger. That's exactly it. Okay. That brings us 

down to our next change, which is an insert just 
below the line "EMS mode, normal." And the change 
is on MSFN cue, "Circuit breaker SPS pilot valve A, 
closed." And a note that goes with this line, 
"l-second burn desired. If no ignition, circuit 
breaker SPS pilot valve A, open, after 3 seconds." 

01 03 35 5^ CDR Okay, iinderstand. Just before EMS mode , normal , 

on MSFN cue, CB SPS pilot valve, closed. A desired 
l-second burn, which means that if we get a light, 
we open the circuit breaker after 1 second. If we 
have no light, you want to leave the circuit breaker 
closed for 3 seconds, and then open it. 



Tape 18/9 
Page 71 



01 03 36 22 CC That - that's - exactly right, Dave. Now I've got 

some words here from Dick Gordon who's run through 
the procedure this morning, and he tells me that - 
that - a good cue to monitor is the SPS PC coming 
off the peg, and, at the same time, Jim or Al can, 
or - or - whoever is there, can - watch the ball 
valve indicators, also, for a cue that the engine 
is starting to "burn. 

01 03 37 00 CDR Okay. Stand by 1 now, Joe. Let us regroup here 

for a minute and make sure that we have no ques- 
tions up to this point. 

01 03 37 06 CC Okay. 

01 03 38 58 CDR Okay, Joe. I guess one question we wanted to make 

sure of here was that the - on the MSFN cue to 
close the pilot valve, is prior to going to EMS 
mode, normal? In other words, we'll never get 
the EMS 



01 03 39 12 CC Nega - negative. 

01 03 39 13 CDR Is that correct? 

01 03 39 1*+ CC Dave, that's negative. EMS mode, normal - - 

01 03 39 18 CDR Okay. 

01 03 39 19 CC And then, on MSFN cue, the SPS pilot valve A, Alfa, 

close , and let me re - repeat here , Dave , that you 
may or may - may or may not get a light at this 
particular point. If you do not get a light, open 
the circuit breaker after about 3 seconds. If you 
do get a light, we're interested in - in as short 
a burn as you can give us, so - and Dick tells me 
that the reaction time - a good reasonable reac- 
tion time would be, in pulling the circuit breaker 
after you see the PC come off the peg, would give 
you about 3 to U feet per second. And that's a 
real good number for us as far the midcourse 2 is 
concerned. 



01 03 ^0 16 CDR Okay. Well, that's why we asked the question. 

Just to make sure. It makes more sense the way 
you're doing it. So , - I guess we understand that. 
We can have - Al watching the PC gage, and Jim can 
watch the ball valves , and if anybody sees some- 
thing move, why - Al can pull that circuit breaker. 



Tape 18/10 
Page 72 



01 03 1+0 33 CC Okay, Dave. That sounds good. Nov a word about 

the circuit breaker. You might want to cycle it a 
couple of times - but before we go through this, 
just to make sure it's not a lot stiff er than 
what you're used to working with in the siraiilator. 
And just get some idea of how it's best to - to 
position yourself to pull this. It's also not all 
that critical that it - that it get pulled abso- 
lutely immediately, but - you know, what - whatever 's 
comfortable to do. It might make it easier for us 
on trimming up with your midcourse if we do get a 
burn. 

01 03 Ul 11 CDR Okay. We'll work that one. Over. 

01 03 hi 15 CC And, before you - you test that particular circuit 

breaker, just make sure that the GROUP 5 circuit 
breakers are open, and we won't be risking anything 
by testing it. Now finally, after this note, we've 
got several deletions, and I'll continue on here. 
Delete "Ullage and thrust, on"; delete "SPS thrust 
light, on"; delete "DELTA-V thrust, E"; delete 
"Ullage and thrust, on"; delete "Monitor thrusting 
PC 95 to 105, EMS counting down." 

01 03 k2 Ik CDR Okay. We got that. Deleting the next seven lines. 

01 03 h2 23 CC Yes, sir; exactly. Now the next line should read 

"SPS INJECTION VALVES, two, OPEN." 

01 03 h2 36 CDR Roger. SPS INJECTION VALVES, two, OPEN. 

01 03 k2 ho CC Roger. Three lines down, delete "PUGS, balanced." 

01 03 k2 hQ CDR Roger. Delete "PUGS, balanced." 

01 03 h2 5h CC And then, the next line, after ignition confirmed, 

circuit breaker SPS pilot valve A - main A, open. 

01 03 h3 16 CDR Okay. After ignition confirmed, CB SPS pilot 

valve A - main A, open. That's - just about what 
you gave us in the notes. 

01 03 43 25 CC Roger. Exactly. And then a note - well, let's 

see. The note is - Just a rehash of what we've 
already told you. The burn shoiiLd not exceed 
1 second if it's possible to avoid it. And then, 
exit T?hj immediately after burn. 



Tape 18/11 
Page 73 



01 03 Us 55 CDR Okay. Shouldn't exceed 1 second and exit PUj im- 

mediately after the bixrn. 

01 03 hk 00 CC Roger. And that takes us to page k-l6. The first 

line - - 

01 03 hh 06 CDR Page k-l6. 

01 03 hk 07 CC Roger. The first line, "DELTA-V THRUST A, OFF." 

01 03 hh 17 CDR DELTA-V THRUST A, OFF. 

01 03 hh 23 CC Okay, Dave. And that's really the end of the pro- 

cedures. We have - another note for this page, 
which is "After test, if SPS light goes out, attempt 
to get lights hack, on by your standard procedures , 
pushing, rapping, cycling, I guess." 

01 03 hh 1+9 CDR Okay. After the tests, if the SPS light is out, 

attempt to get it back on. 

01 03 UU 57 CC Roger. And that completes the procedures. Maybe 

a couple of more words about it here. It's also 
possible that when you push the circuit breaker - 
to the pilot valve A in, that the light will just 
go out, in which case, we'd be pretty confident 
that - the contamination causing the short is just 
a burn through. In other words, just disappeared 
and is no longer shorting the switch. The light 
would go out, and otherwise, nothing else would 
happen. 

01 03 ^5 35 CDR Okay; understand. If we - if when we push the cir- 

cuit breaker in, the light goes out, we've biirned 
to the short. Okay. 

01 03 ^5 HQ CC And, guys, you might look through those again, 

and - if you have any questions , please come 
right back to us with them. 

01 03 U5 58 CDR Okay. Let us mull it over, and we'll get back with 

you. 

01 03 h6 01 CC Okay. 

01 03 hj 35 CDR Okay, Joe. Why, we have no further questions. We 

think we can riin through that one okay. 



Tape 18/12 
Page 7^+ 

01 03 i+T i+5 CC Okay, Dave. And we'll have a pad for you in a 

few minutes. 

01 03 hi 51 CDR Okay, and I guess I still have a question as why 

we don't take a look at that light now with the 
push, rap, and cycle technique. 

01 03 h& Ok CC Let me get a reading on that. 

01 03 1+8 07 CDR Okay. You know, we've tapped it, cycled it, but 

we've never pushed that panel just by pushing the 
panel to see if the light '11 come on.

APOLLO 15 AIR-TO-GROIMD VOICE TRAMSCRIPTION 



01 03 ^8 kk CC Dave, I guess the main reason is, "before you do 

it, we'd like to get some recorders configured. 
We're setting the recorders up now so we can 
monitor the - the problem as you go through it , 
and then there is no reason you can't try pushing 
on the panel, provided the PILOT VALVE breakers 
and the group 5 breakers are pulled. 

01 03 h9 10 CDR Well, Joe, when you get a - a chance, or when 

you're set up down there, why - why don't we try 
that, and at the same time, we could run through 
oxir little check to see how the PILOT VALVE MAIN A 
circuit breaker works, cycling it. 

01 03 i+9 22 CC Okay, Dave, that sounds good. 

01 03 h9 26 CDR We'll stand by until your call. 

01 03 50 30 CC Endeavour, this is Houston requesting POO and 

ACCEPT, and we'll give you a state vector and 
some drift terms. 

01 03 50 38 CDR You got it, POO and ACCEPT. 

01 03 50 kO CC Thank you. 

01 03 52 35 CC Endeavour, this is Houston. 

01 03 52 kO CDR Houston, Endeavour. Go. 

01 03 52 k2 CC Roger, Dave. After you verify for us that your 

pilot valve circuit breakers and group 5 circuit 
breakers are out , you can go ahead with push , 
rap, cycle test if you like. 

01 03 53 00 CDR Okay. Okay. Group 5 are open and the pilot 

valves are open, and we'll take a look at it. 

01 03 53 51 CDR Okay, Houston. Nothing worked pushing and I'll 

try rapping. 

01 03 53 55 CC Okay, Dave. We agree. 

01 03 5^+ 00 CDR Came on with the rap - up Just to the top of the 

switch.

Okay; I'll cycle it and see if it goes off. 
Okay; it flickers as - as I pass through neutral. 
Roger. 

And now she doesn't want to stay on. 

Dave, as long as you keep those circuit "breakers 
out, there's no reason we can't leave that light 
on. We need it on for the test anyway. 

Okay, Joe. I can find a position on the switch 
where I can turn the light out now - in neutral 
position on the switch, if you want to look at it. 
I've cycled the switch a number of times, and I 
think I've got the spot where the light will go 
off, and I'll turn it off for a couple of seconds 
here for you. 

Okay, Dave. Go ahead, and we're watching the 
drivers at the same time. 

Okay, Joe. The light's out right now; Dave's 
holding the switch. 

Roger. We confirm that. 

Okay; it's coming back on now. 

Roger . 

Off now. 

Roger. 

And coming back on. 

And it seeD..s like it goes off just at the lower 
portion or near the off portion of the - force 
range there when you get to neutral. As you go 
into the neutral position, you have high forces, 
and right at the beginning of those high forces , 
it'll go off. And if you hold it in the neutral 
position, or the - the midposition, where the - 
the force on the bottom of the switch, holding 
it so it won't go over center, that's when the 
light will go off. As soon as you let it go 
over center and flick up to the top, the light 
comes back on.

If you want to practice with the pilot valve circuit 
breaker, we emphasize that group 5 circuit "breaker 
definitely should "be open. 

01 03 57 39 CDR Okay, we'll do that now. 

01 03 57 ^1 CMP And the cir - group 5 are open. 

01 03 57 59 CC And, Endeavour, this is Houston with the maneuver 

pad when you're ready to copy.

01 ok 02 57 CC Endeavour, this is Houston. 

01 ok 03 Oh CMP Houston, 15- Go ahead, Joe, 

01 ok 03 06 CC Al, just a couple more words here. We're quite 

interested in subtle changes that may take place 
in the thrust light. And we'd like for you to 
think about perhaps playing around with the cabin 
lighting control there so you can get a good view 
of the light , and you may or may not want to use 
the filter in front of the light as you watch it, 
and I guess the third one of you should be watch- 
ing the light during the burn test. 



Tape 19/lt 
Page 78 



01 Ok 03 h2 CMP Okay, Joe. We'll keep a close eye on the light. 

01 Ok 03 k6 CC Roger, Al. And you understand, it's not a 

question of on/off but also if the intensity 
changes. And - and - - 

01 OU 03 5^+ CMP Yes, affirmative, Joe. 

01 Oil 03 55 CC Roger; okay. And, guys, you can go ahead with 

the waste water dump if you want to now. There's 
nothing magic about the time we gave you on that. 

01 Oi+ oU 10 CMP Okay, Joe. Thank you. 

01 Oi+ Ok 11 CC Roger, Al. And - the provision on that is that 

you be at burn attitude before you dump the water. 
And after the sextant star check. 

01 Ok 13 50 CC Apollo 15. This is Houston requesting BEAM WIDTH 

to WIDE. 

01 Ok 13 59 CDR Okay, we're WIDE, Joe. 

01 Ok 25 kg CC 15, you can terminate the waste dump any time. 

01 Ok 25 ^k CDR We're doing that now. 

01 ok 25 57 CC Okay, guys, and Just want to reemphasize another 

point here. This burn is not at all time critical. 
It has very little effect on - on our midcourse 
corrections later on or whatever. Just want you 
to understand that. 

01 Ok 26 li+ CDR Okay, Joe. We understand that. 

01 Ok 36 01 CC Okay, Endeavour. This is Houston, and we're 

showing about k minutes to ignition. 

01 ok 36 08 CDR Okay, and we've got about 5, and we're proceeding 

throiigh the checklist. 

01 0i+ 36 Ik CC Sounds good. 

01 Ok 39 53 CDR Houston, 15 . 

01 Ok 39 55 CC Go ahead. 

01 Ok 39 58 CDR Okay, Joe. We're all set up and ready to go. We've 

got about 50 seconds to go. Sorry, Joe, there we 
are - Yes, we're ready to go now, any time on your 
cue.

Okay, guys; go ahead. 
Okay , Joe . Ready? 

Mark about 5-3 on the DSKY and about i+.7 on the MS. 
That sounds beautiful, Troops. 
And, Houston, the light's still on. 
Roger, Dave. We confirm that. 
Endeavour, this is Houston. 
Okay ; go ahead . 

Roger, guys. When you are comfortably through with 
the procedure here, we'd like for you to turn the 
thrust light out for us, please, by pulling the EMS 
MAIN A and B circuit breakers, two of them, on 
panel 8. 

01 0l+ hh Oh CDR Roger. They're both open; the light is out. 

01 oh hh 07 CC Okay, Dave^ and that - the reason for that is just 

to conserve that light bulb and a little power, 
and - that burn was exactly what we wanted to see. 
We'll proceed with a normal mission. 

That's nice to hear, 

I'm a smooth talker, aren't I? 

Well, I'm glad you guys down there can figure all 
this out. 

And, guys, a further word here. As you're probably 
already aware, the short is in what we've been call- 
ing the downstream side of that driver solenoid, and 
it means only that it's a little bit annoying to 
have. We can still turn bank A on and off as we 
want . We might modify a few procedures a little 
bit, but we haven't lost that bank. 

01 OU i+5 10 CDR Okay; very good. Thank you, Joe. Let's go to

01 Oh 55 55 CC Hello, Endeavour, this is Houston. 

01 Oh 56 01 CDR Roger, Houston. ... 

01 Ok 56 0*+ CC Roger, Dave. We're requesting a NARROW BEAM WIDTH, 

and then ve have an attitude we'd like you to 
maneuver to for - for a DSE dump which we will 
initiate. Specifically, roll ko , pitch 12, yaw 
50. HIGH GAIN, minus 38 and 3l8. Over. 

01 Oh 56 1*1 CDR Okay, understand. HIGH GAIN is now in NARROW,^ 

maneuver to roll hO , pitch 12, yaw 50. HIGH "GAIN 
is minus 38 and 318. 

01 Oh 56 55 CC Roger, Dave. And after that, we'll need only a 

roll maneuver to get us into the sextant photo 
test attitude. 

01 Oh 57 07 CDR Okay; very good. 

01 Oh 59 20 CC Apollo 15, Houston. 

01 Oh 59 25 CDR Houston, I5. Go. 

01 Oh 59 28 CC Roger, Dave. I'm pleased to report that not only 

did you carry out a successful SPS test burn, "but 
you did a superh midcourse 2 correction at the 
same time. In fact, you b^orned it to within a 
half a foot per second of "being exactly what we 
wanted. Consequently, we're going to omit midcourse 
2 and midcourse 3. We'll be looking at a midcourse 
h correction of around 6 feet per second, it looks 
like now. And, additionally, because of this, 
we'd like for you to go ahead and secure the 
mapping camera and the pam can - pan camera at 
your convenience per the procedure that's shown 
at 31 hours and 10 minutes. Over. 

01 05 00 23 CDR Okay, Joe. Well, we sort of had that in nind 

when we ran the burn. And we'll secure the map 
and pan, and we'll be standing by for midcourse 
h. 

01 05 00 33 CC Roger, Dave. Al Worden always did have a very 

fine touch on the circuit breakers. 

01 05 00 ho CDR Yes, sir. He's - we call him nimble finger up 

here.

01 05 00 55 CDR Okay. 

01 05 02 18 CC Endeavour, Houston. 

01 05 02 2k CDR Go, Houston; Endeavoxir. 

01 05 02 26 CC Roger. Al, for your benefit, we'd scrubbed the 

crew exercise period earlier. We'd like to put 
that back In again, any time between now and the 
sextant photo test. 

01 05 02 Ul CDR Okay, Joe. Jim and Al are doing some housekeeping 

now, and we're going to make sure we get all the 
exercise periods for you. 

01 05 02 51 CC Roger, Dave. I'll rely on you for that. 

01 05 02 57 CDR Gee, we might even do a couple extra. 

01 05 05 20 CC Endeavour, this is Houston. Please start your 

battery A charge at yoiir convenience. 

01 05 05 27 CDR Okay, start battery A charging. 

01 05 05 30 CC Okay, Dave. And we do have one question regarding 

the burn. On our data down here, we saw the thrust 
light go off right after the burn for about T 
seconds and wondered if you noticed the same thing 
up there. 

01 05 05 52 CDR Stand by. 

01 05 06 11 CDR Houston, the consensus here is that it stayed on, 

and I guess - we - we might have missed a short 
period there in getting the engine off and getting 
out a Fk'J , tut Al and I both feel like it stayed 
on all the way, but I guess we're not a hundred 
percent sure of that. 

01 05 06 29 CC Okay, Dave. We copy. Thank you.

01 09 23 07 CC 15, this is Houston. Time is not too critical. 

We'd like to let it vent a little longer. Tjry to 
get 3.1. If we don't reach it in about 5 minutes, 
we'll probably go ahead. 

01 09 23 19 CDR Okay J understand. 

01 09 29 59 CDR Okay, Houston; 15. We're reading 3.1 now. 

01 09 30 10 CC 15, Houston. That's excellent. I guess we can 

go ahead with pressure - pressurizing the LM. 

01 09 30 18 CDR Okay, 

01 09 1+1 26 CC 15, this is Houston. Can you tell us how the pres- 

surizatlon is going? 

01 09 I4I 32 CDR Oh, we're all squared away, and the probe is com- 

ing out. 

09 09 1*1 1+1 CC Roger. And - if you could give us the high-gain 

angles there, we'd like to get that going.

01 09 h3 52 CC Thank you. 

01 09 ^6 22 CC 15, this is Houston. Whenever you have a chance 

up there, we're interested in seeing some TV. 

01 09 hG 30 CDR Roger, Houston. We thought we'd get the tunnel 

cleared out because, with all that extra gear in 
the command module, it's sort of tough to find a 
place to stow everything. And the TV is - right 
now, sort of in the way. So we'll try and get to 
you as soon as we can. 

01 09 U6 kh CC Okay. 

01 09 h6 52 CDR It's a new world in this command module, with all 

these extra box - boxes and everything.

01 09 h8 1+2 CDR Roger. We had an AC BUS 2 light and a MAIN BUS B 

UNDERVOLT. Voltage looks good, and AC BUS 2 looks 
good. Reading 28.5 volts on MAIN BUS B, and AC 
BUS 2 looks good. About that time we had a loss 
of S-band. I don't know whether it was coinci- 
dental or not . 

01 09 h9 05 CC We copy. 

01 09 i+9 h2 CC 15, this is Houston. We saw some of those problems 

here on the ground, too. And we would liie to get 

back on the high gain, if you would reacquire. 

01 09 h9 56 CDR Okay. 

01 09 50 k6 CDR Okay, Houston. You should have the high gain now.

01 10 33 06 LMP We ought to go back to LO bit rate. 

01 10 33 07 CDR Yes. One little problem we ought to discuss with 

you before we go on. It seems that somewhere alon^ 
the way, the outer pane of glass on the tape meter 
has been shattered. I don't know whether you can 
get a picture of it on the TV or not; we'll get Al 
to try and zero in. But about 70 percent of the 
glass is gone. The inner pane of glass seems to 
be okay. There's no apparent damage to the tape 
meter itself. It's sitting on 520 and h82. But, 
I don't know whether you can see it or not, but 
I'll trace the area which is missing with my 
finger here. And it looks like the pieces we 
found - I found one piece that's almost an inch 
in size, and there's some smaller ones around. 
We'll try to pick it up with the tape, and then 
get the vacuum cleaner later on - to get it all up. 
So far that's the only obvious discrepancy we've 
found.

01 12 30 16 CC 15, this is Houston. This is Houston; go ahead. 

01 12 30 27 LMP Yes, Karl, this is Jim. I'm back in and on comm. 

As far as that AC and main bus undervolt , I have 
not much more to add than what I said before. Do 
you have any other questions? 



01 12 30 kk CC 



Roger. Stand by just about 30 seconds, and we'll 
come up with a couple . 



Tape 2U/3

01 12 30 51 LMP Okay. 

01 12 31 32 CC 15, this is Houston. 

01 12 31 38 LMP Go ahead, Karl. 

01 12 31 ^1 CC Jim, we've heen doing a lot of thinking about that 

AC glitch down here, and - the coincidence of time - 
makes us guess that there is a connection with that 
power loss, "but we don't see how. We'd like to 
start off with a couple of questions. The first 
one is , when you - reacquired on the high gain 
antenna, did you possibly notice that the high gain 
angles were different from what you'd set on the 
knob s ? 

01 12 32 13 LMP Yes; as a matter of fact, they were. 

01 12 32 l6 CC Okay. 

01 12 32 20 LMP I - I did nothing up here to reacquire on the - the 

high gain. It came back automatically. 

01 12 32 27 CC Okay; that's interesting information. Were there 

any talkbacks noted changing state at the time of 
the glitch? 

01 12 32 37 LMP No change that I noticed. 

01 12 32 *+l CC Okay. Was anyone in the tunnel at the time of the 

glitch? 

01 12 32 50 LMP Say again about the tunnel, Karl. 

01 12 32 52 CC Was anyone in the tunnel at the time of the glitch? 

01 12 33 oh LMP Stand by. 

01 12 3h 12 LMP Okay, Karl. Al was in the tunnel, but there were 

no electrical connections being made at the time. 

01 12 3^ 20 CC Roger. 1 - I guess a follow up question then — 

and you've probably answered it — is, was there 
any unusual activity associated with the tunnel 
umbilicals? 



Tape 2k /k 
Page 108 

01 12 3h 37 MP Don't think so - we don't think so, Karl, not at 

that time. 

01 12 3k kl CC Okay. And another question on this line is, what 

was and what is the position of the LM power 1 
main B and 2 main B circuit breakers on panel 5? 

01 12 3h 5k LMP Stand hy. 

01 12 35 Ok LMP They're hoth in. 

01 12 35 08 CC Roger. 

01 12 35 18 CC Okay. If you have some minutes to spare up there, 

we'd like to go through a cockpit check for open 
circuit breakers connected with main B and AC 2, 
on the theory that whatever happened might have 
blown a circuit breaker that wasn't obvious to you. 

01 12 35 37 LMP Okay. I'll - I'll do that now. 

01 12 35 kO CC We suggest - that - well, you know, this - figures 

3-1 and 3-2 are a good guide to that for the nor- 
mally open circuit breakers. 

01 12 35 53 LMP I'll check all circuit breakers. 

01 12 36 22 CC Jim, I've got the diagrams down here, if there's 

anything I can do to help you. 

01 12 36 30 LMP Okay; we'll look around. 

01 12 38 23 LMP Karl, this is Jim. 

01 12 38 26 CC Go ahead. 

01 12 38 30 LMP Roger. On 226, under LIGHTING, NUMERICS /INTEGRAL, 

LEB AC 2 has been popped, or I believe it's popped. 
I would think it'd normally be closed now. 

01 12 39 06 CC Roger, Jim. We confirm that that is normally closed. 

01 12 39 13 LMP Okay; it looks like it might be the problem. 

01 12 1+9 1+8 CC 15, this is Houston. 



Tape 2U/5 
Page 109 



01 12 1+9 56 IMP Go ahead, Karl. 

01 12 1+9 57 CC Wtien you're through checking the circuit breakers, 

we have a little procedure we'd like to go through 
here as - as a further check. 

01 12 50 08 LMP Okay. Did you want me to continue checking? 1 

figured after I - Stand by. 

01 12 50 IT CC Roger, Jim. We - we'd like to have a - a complete 

check there, and don't - don't reset that circuit 
breaker, incidentally. 

01 12 50 25 LMP I understand. 

01 12 51 58 LMP Okay, Karl. I've checked all circuit breakers, and 

that's the only one that seems to be out of 
configuration. 

01 12 52 0I+ CC Okay; very good. What we're going to do, Jim, is 

to drop the up-link and see what happens. And just 
to clarify the commmi cat ions glitch that we had, 
the ground station lost the power amplifier, and 
we lost up-link to you. There was apparently no 
loss of down-link. So what we want to do now is 
to - is to c^rop the up-link and see if it creates 
the same glitches that - as you got on the AC bus 
that time. In view of your circuit breaker being 
out, we don't think there's a connection, but we'd 
just like tc have this final confirmation. And - - 

01 12 52 h3 IMP Okay; we're standing by. 

01 12 52 1+1+ CC - - to start the procedure here, we'd like to just 

double check that you - that the dials for the 
HIGH GAIN A,')ITEKNA are setting at PITCH, minus 30; 
YAW, 276. 

01 12 52 58 LMP Yes, that's correct. 

01 12 53 00 CC Roger. And verify that we have - - 

01 12 53 02 LMP YAW - YAW is really - - 

01 12 53 07 CC Go ahead. 

01 12 53 08 LMP Yes, we're in TRACK, AUTO. 



Tape 2i+/6 
Page 110 

01 12 53 10 CC We - we'd like to have AUTO and NARROW. 

01 12 53 12 LMP YAW is - - 

01 12 53 23 LMP PITCH is minus 30, YAW is 270, and TRACK is AUTO. 

01 12 53 hh CC Roger, Jim. And what we're going to do now is to 

drop up-link for 20 seconds, and you are to read 
and record the high gain antenna dials and any 
changes that occur there. Then we'll bring up the 
up-link; and, at that time, we want you to require - 
reacquire HIGH GAIN ANTEITNA on - on AUTO, NARROW. 
Okay? 

01 12 5^4 10 LMP Okay. Right now the YAW indicator is reading 

about 280. 

01 12 5^ 19 CC What does your dial say? 

01 12 -^k 2k LMP The dial is 280. The thumbwheel is 270. 

01 12 5U 31 CC That's okay. And are you ready for us to drop 

the up-link? 

01 12 '^k 39 LMP Go ahead. Yes, go ahead. 

01 12 5^+ ^6 CC Okay. We'll be dropping - dropping the up-link 

for 20 seconds. Here we go. 

01 12 56 07 CC 15, this is Houston. How do you read? 

01 12 56 13 CDR This is 15. I read you loud and clear. 

01 12 56 16 CC Roger. Did you observe anything special up there? 

01 12 56 22 CDR Nothing other than the - the PITCH went to 0 , and 

the YAW decreased Just very slightly. And, of 
course, when you reacquired, it went back to - 
PITCH went >)ack to 30. 

01 12 56 39 CC We copy, 

01 12 58 Oh CC 15, this is Houston. That's enough troubleshooting, 

and we're ready to go to PTC now. And we'd like to 
have you use the A and D quads for damping. And 
use the B and D quads for spinup. And we'd like to 
confirm that we are using a spin rate of .375 this 
time . 



Tape 21+/7 
Page 111 

01 12 58 35 LMP We copied all that, Karl. A and D for damping, 

B and D for spinup. And .375 for the rate.

to go into spinup, if all of your vents have "been 
closed. 

01 13 11 08 CDR Okay, Karl. I think we got everything closed,

here that A-1 jet is on - could you confirm that? 
And if it is on, let's turn it off. 

01 13 20 22 CMP Roger, Houston; 15. Your read-out is correct 

and it's now off. Sorry, Karl, I overlooked 
that one. 

01 13 20 28 CC Thank you. 

01 13 23 ^1 CC 15, this is Houston. Your spinup is looking very 

good to us , and when you have a couple of minutes 
to listen, we have a brief status report to send 
up to you. 

01 13 23 56 CDR Okay; go ahead, Houston. We're standing "by. 

01 13 2h 01 CC Okay. In regards to your range rate tape 

meter - That is normally sealed in a helium 
atmosphere at 15 psi, and with that outer glass 
broken, this seal is broken and the meter is 
now operating in 0 to 5 psi in an oxygen 
environment. We don't know that this has any 
effect on it, but Grumman is doing tests to show 
whether or not it's okay. Concerning the SPS - - 

01 13 2h 3^ CDR

01 13 2k 36 CC Yes, go ahead. 

01 13 2k kO CDR I was just going to say, it would be interesting 

to hear what they find out. 

01 13 2h kk CC Roger, we'll let you know. Concerning the SPS, 

we're still reviewing the LOI procedures that 
we'll use, hut it's probable that we'll want 
to start automatically on bank B and bring on 
A 5 seconds later, using the circuit breaker, 
and then turning it off at 6 minutes and finishing 
up the burn on bank B. It's probable that the 
other burns, except for TEI, will be done on 
bank B only. Any comments on that? 

01 13 25 23 CDR No, that's Just about what we were thinking too, 

Karl. 

01 13 25 27 CC Okay. In the LM, the batteries and the SHe look 

in perfect shape, and concerning the lighting 
circuit breaker problem, we're still getting in 
the data in down here, and we'll review the 
situation with you tomorrow. We see no problem 
with the high gain antenna. And other than your - 
and other than yoiir crew status report and your 
onboard read-out, that just about wraps up the 
evening. We'd still like to have your PRD read- 
outs, and I guess we have a battery charge in 
progress that will need to be cut off. 

01 13 26 l6 CDR Okay, Karl; we'll finish up the rest of the items 

here and bring you up to date on all the read-outs, 
and - Sorry about the PRDs, but since ... tonight. 

01 13 26 33 CC Okay. No problem on that. And I have a - I have 

the update to the LM Contingency Checklist, and 
if you want to take it this evening, I can give 
it to you; otherwise, it can be put off until 
tomorrow. 

01 13 26 58 CDR Okay, stand by.

drawings. In national news - Now, we may he \ise - 
losing conmunications now; I'll stand hy a minute. 

02 01 13 50 CC 15, are you reading Houston clearly? 

02 01 13 55 CMP Roger, Joe; we're back with you. 

02 01 ll+ 00 CC All right. Moving right along, now, the national 

news. Secretary of Labor Hodgson has asked the 
United Transportation Union and the rail industry 
to put their dispute before a neutral panel for 
settlement. U.S. Senate will vote today on an 
amendment to delay a federally guaranteed loan to 
Lockheed. The vote is expected to be very close. 
In local news, a Texas Animal Health Commission 
employee said that he thinks that the Harris 
County vaccination program against sleeping sick- 
ness is almost at an end. I don't know if they're 
going to institute preflight quarantine on the 
animals or not. And more than a hundred people 
were arrested during a raid of the Arlington Country 
Club in Texas, last night, and gambling equipment 
was confiscated. Maybe you left town Just in time. 
In sports, yesterday, the Baltimore Orioles 
increased their lead to four games in the American 
League East by winning the double header from the 
Oakland Athletics, 1-0 and 6-k. And the Houston 
Astros split a twilight double header last night 
with the Phillies, 8 to 3 and 5 to 1. Muhammad 
All announced that - and I'll stand - all right, 
Muhammad Ali announced that he will fight Jerry' 
Quarry, September, in the Astrodome and Ali also 
wants a reijatch with Joe Frazier sometime in 
March, 1972. The Oilers have trimmed their roster 
to 59 players by placing two of the players, 
Johnny Peacock ajid Tom Smiley, on waivers. Four 
golfers were inducted into the American Golf Hall 
of Fame last night. They are J\;ilius Boros, Gary 
Middlecoff , Jock Hutchinson, and the late Walter J. 
Travis . And we hate to tell you this , but 
Elizabeth Taylor is a grandmother, at age 39 when 
her 19-year-old daughter-in-law gave birth to a 
6-pound, 2-ounce girl yesterday. And that's all 
from the Houston MOCR News Center. 

02 01 l6 31 CMP Okay, Joe. Thank you very much for the weather 

and news this morning.

02 01 16 kO CC Okay, Al. And I have a CSM consumables update and 

a number of other things, when you're ready to 
listen to them. 

02 01 16 55 CMP Okay, Joe; stand by 1. 

02 01 16 58 CC Roger. 

02 01 19 UO CMP Houston, this is 15. We are ready to copy the 

consumables updates . , , 

02 01 19 50 CC Al, stand by. We're not receiving you clearly. 

02 01 19 56 CMP Okay. We'll stand by. 

02 01 20 02 CC Roger; it's veiy weaJc and severe noise in the 

background, I5. We're standing by for better 
comm. 

02 01 20 12 CMP We understand. 

02 01 21 5i+ CC Al, this is Houston. The noise seems to have 

quieted down again. Why don't we give it another 
try/ 

02 01 22 09 MP Okay. Joe. Would you like to copy our consumables 

and then yoy can pass up S-band. 

02 01 22 19 CC Okay. 

02 01 22 23 LMP Okay, RCS, 90, 89, 90, and 89. On H^, 92. 90, 70. 

O^i 90, 90, and 85. 

02 01 22 U5 CC Roger. Jim. We copy all that. Let me give you a 

set of figures here. They agree very closely to 
what you've read to us. At GET hd plus 00; the 
RCS total was 8T; and then quad A, 86, 87, 86 87 
H^ tank, 92, 92, 70. 0^ tank, 90, 92, 85. Over.* 

02 01 23 3k LMP Okay, I copied all those. As far as sleep, Dave 

figures 8 hours in two segments ; Al was 8 hours 
for two; and I figure I got 9 hours in about three 
segments. 



02 01 23 55 CC 



Roger; we copy that. Sounds like that's the most 
sleep you've had in several months. Out of 
curiosity, since we're coming up on this eye-flash 



Tape 32/4 
Page 126 



experiment, I wonder if any of you has noticed 
any of the flashes yet? 

02 01 2h 11 IMP Yes, we have noticed them both nights, Joe. 

02 01 2h 15 CC Okay; I guess we'll talk more about that a little ^ 

later on. I have a number of other things to reat 
up to you, in whatever order you'd like. They 
include a fairly extensive Flight Plan update, 
nothing profound but it will require some - certain 
amount of writing and then a few miscellaneous 
questions which we'd like to ask you. 

02 01 2h h5 mP Ok - okay; I guess I can start on the - these 

Flight Plan bit. 

02 01 2k 5h CC Okay, Jim. And are you the recording secretaiy 

this morning? 

02 01 25 01 LMP Yes. 

02 01 25 lU CC Okay, Jim. Before we start, did you get the 

radiation dosimeter readings for us? 

02 01 25 23 IMP We reported them last night. Do you want them 

again this piorning? 

02 01 25 29 CC Apparently, we'd like them again the - the - this 

morning on the schedule. 

02 01 25 36 LMP Okay; stand by. 

02 01 27 11 LMP Okay, Joe, I have a radiation report for you. 

02 01 27 15 CC Go ahead. 

02 01 27 21 IMP Okay, radiation. Qn Dave is 23023; Al, 25009; 

and mine is O8OIO. 

02 01 27 hh CC We copy those, Jim; thank you. And normally, I 

guess, we'd like those in the postsleep period 
as opposed to presleep, which is when we got thera ^ 
yesterday. I guess it's in the checklist that waj- 

02 01 28 00 IWP Okay, we'll - okay, we'll normally do it that way. 

02 01 28 05 CC Okay; fine, and I'm ready to start with the Flight 

Plan update. When you're set up to copy there 
I'll start at about 5U:50. ' 



Tape 32/5 
Page 127 

02 01 28 20 IWP Okay, let me get to 5h:50. 

02 01 28 22 CC Fine. Jim. And we're coming up on an OMNI switch 

When we're on the new antenna. I'll start to read. 
You might want also your IW Activation Checklist 
handy because we'll he using it later on. 

02 01 28 38 IMP Okay.

APOLLO 15 AIR-TO-GROUND VOICE TRANSCRIPTION 



02 01 31 hh IMP Houston, how do you read 15? 

02 01 31 1;8 CC Jim, you're loud and clear, and we're ready down 

here if you are. 

02 01 31 53 IMP Okay. I'm at 5^:50 on the Flight Plan. 

02 01 31 57 CC Okay. Before I start into it step by step, let me 

Just say that it's basically - the - the change is 
basically moving some of the items around in time, 
and there's not many changes in procedures involved. 
The one main thing is we're going to ask you to go 
into - into the LM a little early, I guess, earlier 
than you had planned. And we're going to also re- 
quest that you give us enough - you bring enough of 
the telemetry on line so we look at the - can look 
at the LM batteries. And there's no particular 
reason we want to do this today. Nothing that we 
suspect is wrong, but rather, apparently, the sys- 
tems people are interested in a better granularity 
in data points that they're taking on these bat- 
teries. That's the reason for this particular 
addition. Other than that, I think there's no - 
nothing at all very - very different about this 
Flight Plan update, other than a few minor changes. 
And I'll go ahead and start if you're ready. 

02 01 33 11 LMP Okay. I'm ready, Joe. And we understand. 

02 01 33 15 CC Okay; 5^:50, the step "If LM/CM DELTA-P less than 

2.7 psid, LM TUNNEL VENT valve, panel 12, vent 
imtil DELTA-P greater than 2.7 psid." 

02 01 3h 15 LMP Okay. I have "If LM/CM DELTA-P, is less than 

2.7 psid, LM TUNNEL VENT valve on panel 12, vent 
until DELTA-P greater than 2.7 psid." 

02 01 3^ 29 CC That's correct. Now turn one page to 55 plus 15. 

02 01 3h HQ LMP Okay; I'm there. 

02 01 3^4 51 CC Okay. Insert "Stop PTC at roll 50 degrees. HIGH 

GAIN ANTENNA angles: PITCH, minus 1+8; YAW, 
plus 82." 



J 'age 130 



02 01 35 25 LMP Roger. "At 55:15, stop PTC roll 50 degrees; HIGH 

GAIN AUTMNA: PITCH, minus h8; YAW, plus 82." 

02 01 35 37 CC That's correct. Now, turn back several pages to 

3-5^, please. And that's the "Cycle Film in Pan 
and Map Cameras" page - procedures page. 

02 01 35 58 LMP Okay; I have it. 

02 01 35 59 CC Okay. Down near the bottom, delete the line "SM 

SECTOR 1, SM/AC POWER, OFF." And add in its place 
"MAP CAMERA on - that should read "MAP CAMERA on 
STAFDBY/talkback gray." Over. 

02 01 36 3h LMP Okay; understand. Delete "SM SECTOR 1, SM/AC 

POWER, OFF," and add "MAPPING CAMERA on to STANDBY/ 
talkback gray." 

02 01 36 h6 CC That's correct. Now, turn back to 55 plus 50, and 

there's a long series of deleted activities that 
will follow. These - All because we're not going 
to do a midcourse 3, as you're well aware. And 
I'll call them out line by line, and they'll carry 
through for - I guess about a page and a half here. 
At 55:00. 

02 01 37 20 LMP Okay; go ahead. 

02 01 37 22 CC Delete "P30 external DELTA-V" and "Ykg maneuver to 

pad bum AT?." Turn the page. Jim, I've apparently 
made a mistake on that. That should have been 55:50. 
I think you're at the right - the right place. Con- 
tinuing on over to 50 - - 

02 01 37 50 LMP Yes; I got it. 

02 01 37 51 CC Roger. Continuing to 56 plus 00, delete the next 

seven lines up to the two lines which you should 
leave in: "0 FUEL CELL PlfflGE" and "WASTE WATER 
DUMP." 

02 01 38 1^ U4P Okay; I have that. 

02 01 38 l6 CC Okay. Continuing - continue deleting the lines 

below that, down to 57 plus 00. 



Tape 33/3 
Page 131 



02 01 38 37 LMP Okay. So the only two actions we have on that 

page, 56 hours, is the "0 FUEL CELL PURGE" and 
the "WASTE WATER DUMP." 

02 01 38 hk CC That's affirm. Nov, once again backing up to the 

time, 55 plus 50. That should read "VERB 1+9 maneu- 
ver to LM checkout attitude," and that attitude is 
"305, 090, 000. HIGH GAIN angle: PITCH, minus 30; 
YAW, 2T6." 

02 01 39 5^+ LMP Okay. "VERB h9 maneuver to LM checkout attitude" 

at 55=50; the attitude "305, 090, and 000; HIGH 
GAIN: PITCH, minus 30; and YAW, 276." 

02 01 ho 11 CC Readback's correct, Jim. I'll stand by mtil we 

get another OMNI change. 

02 01 i+0 19 LMP Okay. 

02 01 k2 1+8 CC 15, Houston. Our comm's quieted down again, and 

I'll continue if you're ready. 

02 01 1+2 58 LMP Okay. I'm ready, Joe. 

02 01 1+2 59 CC Roger, Jim. At 56 plus 50, start "CSM Systems 

Checklist, IVT to LM," and this is an item that's 
moved up from 57:20, by the way. 

02 01 1+3 3h LMP Okay. At 56:50, start "CSM Checklist, IVT to LM." 

02 01 1+3 1+3 CC That's correct, and you are to start that checklist 

from the beginning. And at 57 plus 00, you move 
the CSM PTC procedures to completion of our LM 
battery checkout. And I guess that's an item for 
Al. 

02 01 1+1+ 21 LMP Okay; understand. We'll move all that there for 

the PTC until after we complete the battery checkout 

02 01 1+1+ 30 CC That's correct, and that shoiild come around 57 

plus 50 or perhaps a little later. But, once again, 
not time critical. We're coming up on 57 plus 30. 
And, if you'll take out your LM Activation Checklist 
page 1-1, please. 



02 01 1+5 11 LMP 



Okay; I have it. 



Tape 33/li 
Page 132 



02 01 1+5 Ik CC Okay. And this is to start at 57 plus 30. Perhaps 

you should put a mark in your time line, but then 
on - on the checklist from page 1-1, delete " Coram 
carrier, CWG connector." Delete step 2. Delete 
step 5. 

02 01 1+5 5^4 LMP Okay. On 1-1, I delete "Comm carrier, CWG con- 

nector;" step 2; and step 5- 

02 01 1+6 01+ CC That's affirm. Do page 1-13. And if you'll turn 

to that, do 1-13, except in step 2. 

02 01 1+6 31+ CC In step 2, delete "VHF B TRANSMITTER, close; VHF A 

RECEIVER, close; CDR AUDIO, close." And add the 
instruction "CB 11, ECS CABIN FAN, close." 

02 01 1+T 21+ LMP Okay, Joe. On 1-13, under step 2, to delete "VHF B 

TRANSMITTER, close; "VHF A RECEIVER, close; COM- 
MANDER AUDIO, close." And add "CB 11, ECS CABIN 
FAN, close." 

02 01 1+7 38 CC That ' s correct , Jim. Do page l-ll* , except in 

step 5. Delete "VHF A TRANSMITTER, close; VHF B 
RECEIVER, close;" and delete step 6. 

02 01 1+8 15 LMP Okay. On I-II+, we'll do all that. Under step 5, 

we'll delete "VHF A TRANSMITTER, close; VHF B RE- 
CEIVER, close;" and want to delete step 6. 

02 01 1+8 28 CC Readback's correct, and add step T- Your comm 

S-BAND configuration is "PM, SECONDARY, PRIMARY, 
OFF; PCM, OFF/RESET, OFF, and HI." 

02 01 1+9 03 LMP Okay. The S-BAND configuration is "PM, SECONDARY, 

PRIMARY, OFF; PCM, OFF/RESET, OFF, and HI." 

02 01 1+9 11 CC That's correct. We'll want you to stay in the con - 

configuration for 15 minutes while we take the data. 
After that time, do page I-I8 and 1-19 . 

02 01 1+9 32 LMP Understand to stay in that configuration for 15 min- 

utes, then do I-I8 and I-I9. 



Tape 33/5 
Page 133 



02 01 1+9 38 CC Okay, Jim. Sounding fine. Now, back into your 

time line. At 57 plus U5 , proceed with LM house- 
keeping. And we've got some words here on the 
housekeeping. I'll read them to you, and I guess - 
Copy down whatever you think you haven't done yet. 

02 01 50 lU LMP Okay; understand. At 57:1*5, we're to proceed with 

LM housekeeping, and go ahead with the - your steps, 
Joe. I'll note them down. 



02 01 50 22 CC Okay. Vacuum cahin fan filter. And as a subgroup 

under this , you unsnap netting around cabin fan 
filter. 

02 01 50 52 CC Then you vacuum the filter. But do not scrub 

bristles of the vacuum cleaner over the surface 
of filter. Then, you remove the remaining parti- 
cles on cabin fan filter with sticky tape, using 
care not to dislodge filter material. 

02 01 51 39 CC Then, you remove the particles on the inlet screen 

of the vacuum cleaner with sticky tape; and, finally , 
replace the netting. 

02 01 52 17 CC And, Jim, that's the end of that procediire. Our 

coram' s starting to fade out on us, so we may not 
be able to copy you. Hopefully, you're copying 
us clearly still. 

02 01 52 29 LMP Yes , we are , Joe . I got that . . . 

02 01 53 18 CC Okay, Jim. And just an added note on that. As 

you're well aware, we're interested in cleaning 
up as many of those fine glass particles as we 
can, which is primarily the reason for - for this 
procedure. 

02 01 53 36 LMP Yes; we quite agree, Joe. 

02 01 53 38 CC Okay. At the time 57 plus 1+5, the steps "S-BAND 

AUX, TV to SCIENCE, PAN CAMERA POWER to on," and 
then in parenthesis, "for 5 minutes /OFF. " and 
finally, "S-BAND AUX, TV to off." 



Tape 33/6 
Page 13I+ 

02 01 5^+ 29 LMP Okay, Joe. At 57:1^5, understand you want the 

"S-BMD AUX, TV to SCIENCE." Then I missed the 
information after - after that, and then, finally, 
the last one vas "S-BAHD AUX, TV to off." 

02 01 51* k& CC Okay, Jim. What we're interested in here is look- 

ing at the pan camera temperature. And the center 
step, the one you missed, reads "PAN CAMERA POWER 
to on for 5 minutes and then OFF." 

02 01 55 18 LMP Okay; understand. "PAN CAMERA POWER to on for 

5 minutes and then to OFF." 

02 01 55 26 CC That's correct. At 57 plus 50, "CSM proceed with 

PTC activation." 

02 01 55 53 LMP Okay. At 57:50, "CSM proceed with PTC activation." 

02 01 56 00 CC Roger. And turning over a page to 60 hours. After 

the step "S-BAND AUX, TV-off," add "PAN CAMERA SELF 
TEST to off." And - - 

02 01 56 22 LMP Roger, Joe. 

02 01 56 33 LMP Joe, do you read me now? 

02 01 56 35 CC Okay, Jim. Reading you loud and clear. 

02 01 56 1^0 LMP That last information you gave me on S-BAND AUX, 

TV. I add that - I added that in at 57:1+5. Is 
that correct? 

02 01 56 5^ CC Jim, no; negative. Turn over the page to 60 hours, 

60 plus 00. 

02 01 57 08 LMP Okay; I have 60 hours. 

02 01 57 22 LMP Okay, Joe. I'm at 60 hours. 

02 01 57 2h CC Okay, Jim. This is a new step completely at 

60 hours. We did say something at 57:1|5. I'll 
come back to that in a minute to make sure that's 
straightened around. But at 60 hours , after the 
step in the Flight Plan, S-BAND AUX, TV to off, 
add two steps. And they are "PAN CAMERA, SELF TEST 
to off" and "MAP CAMERA, ON to OFF." Over. 



Tape 3VT 



02 01 58 10 LMP Okay; understand. Two steps there after "S-BAKD 

AUX, TV-off." "PM CAMERA, SELF TEST, off" and 
"PAN [sic] CAMERA, ON to OFF." 

02 01 58 23 CC That soxmds - that sounds good, Jim. 

02 01 58 30 LMP Let's go back to 57:^5- 

02 01 58 k2 CC Okay, Jim. At 57:^5, the three steps you added in 

there should be "S-BAHD AUX, TV to SCIENCE; PAN 
CAMERA POWER, on for 5 minutes and then off; and 
S-BAKD AUX, TV, off." 

02 01 59 03 LMP Okay; understand that. I guess I got a little 

confused there, Joe, when you said turn the page, 
and you turned several pages to get to 60 hours. 

02 01 59 16 CC I think you caught me in that. I guess I did. 

Sorry. 

02 01 59 26 LMP Okay. I'm ready to go on to the next one, Joe. 

02 01 59 31 CC Okay, Jim. That completes the Flight Plan update, 

and you should know by now that you have to take 
me for what I mean, not for what I say. I do 
have - - 

02 01 59 it3 LMP We did. 

02 01 59 ^5 CC Roger. I q.o have a note, which you can put down 

in the margin or wherever, and it involves sub- 
sequent P23 sightings as required. 

02 02 00 05 LMP Okay. 

02 02 00 10 CC And the note is "Reduce trunnion to less than 

10 degrees before zeroing optics." And then, 
"Always do optics calibration after optics zero 
in P23." 

02 02 01 02 LMP Okay, Joe. For subsequent P23 sightings, we're 

to reduce the trunnion to less than 10 degrees 
before zeroing optics, and always do the optics 
CAL after the optics zero in P23. 



Tape 33/8 
Page 136 



02 02 01 13 CC That's exactly right, Jim. And that is all I have 

on my Flight Plan update. I guess we've got an 
afterthought here. I'll get with you in a minute. 
I do have - some other questions which I'd like to 
ask, but let - let me give you this addition while 
you have the Flight Plan there on your lap. And 
it involves the time 56 plus 20. I'll stand by 
when you're there. 

02 02 01 59 LMP Okay. I'm at 57 - 56:20. 

02 02 02 03 CC Okay. The step is "Direct 0 open until cabin 

pressure equals 5-7 psia." 

02 02 02 31 LMP Okayi understand. At 56:20, "Direct 0„ open until 

cabin pressure equals 5.7 psia." 

02 02 02 37 CC That's correct. 

02 02 02 k9 CC And, Jim. I'm going to wait until the coram gets 

a little better before I continue on here. Be a - 
a minute or so. 

02 02 02 58 LMP Okay. 

02 02 05 53 CC Apollo 15, Houston. 

02 02 06 05 LMP Go aiiead, Joe. 

02 02 06 07 CC Jim, we've got about three or four small questions 

for you. Your choice whether you'd like to talk 
about them now or proceed on with the light-flash 
experiment . 

02 02 06 18 LMP No. We're going to delay that light-flash experi- 

ment anyway lentil we get cleaned up here and have 
breakfast. So you can ask - ask the questions. 
We'll be thlrjting about it while we're cleaning up. 

02 02 06 30 CC Okay. That sounds good. Our first one, we noted 

a very small load change on battery bus A yester- 
day, several minutes prior to your SPS burn, and 
we're trying to - to chase down what may have caused 
this. We suspect that you may have - have closed 
two circuit breakers that should have been closed 
and just are curious to know if you did close them, 
or if when you looked to verify them, they were 



Tape i i/y 
Page 137 



already closed. And, the circuit breakers in 
question are the SPS PITCH 1 and YAW 1 circuit 
breakers that feed BAT A. 

02 02 07 22 LMP Okay. We - we closed those per checklist, Joe. 

02 02 07 27 CC Jim, I understand you closed them per the check- 

list. By that do you mean that you - when you 
looked at them, you found them open and closed 
them? 

02 02 07 53 LMP Okay. That's firm, Joe. They were open, and we 

closed them per the checklist. 

02 02 08 01 CC Okay. The guys in the back room here psyched that 

out pretty well, I guess. Thank you. That - I 
guess that was a question mostly of academic in- 
terest. Al, the circuit breaker in the lower 
equipment bay, AC 2, is still out as you're well 
aware , and it affects a number of EL and DSKY 
lights and so on, and we'll want to talk to you 
later on today about this. It should be no prob- 
lem in any way, but we do want to talk about - 
discuss ramifications of the - of the -various 
workarounds which this may involve. And, finally, 
we've been noting during the night some small 
oscillations in accumulator quantity, and we'd 
like for you, please, to check your SECONDARY 
RADIATORS. Verify that's in BYPASS. That's 
panel 377-

was in BYPASS, and Dave Just cycled it to - cycled 
it to NORMAL and then back to BYPASS. 

02 02 11 01 CC Okay, Jim. Thank you. And that's all we have 

down here for the time being. I've been reading 
the Apollo 15 Status Report that's put out every 
2 hours. What's normally several pages is just a 
page today. And - with very few words on it, the 
most prominent one being the word nominal, the 
meaning of which I'm going to look up as soon as 
I get off this shift.

02 03 23 11 CC Go ahead, 15- This is Houston. 

02 03 23 17 CDR Okay, Houston. We're getting ready to do the 

light-flash experiment, and we'd like to run the 
tape recorder so we can get the voice marks on it, 
if that won't interfere with any of your ... 

02 03 23 35 CC Okay, Dave. Stand by. I'll inquire.

02 03 25 05 CC 15, this is Houston. 

02 03 25 12 CDR Houston, 15. 

02 03 25 lit CC Roger. In answer to your question on the DSE, 

we'll handle the DSE from down here when we start 
the eye-flash experiment. We do have a - a request 
of you "before you start the experiment, though. 
We don't have the necessary oxygen purity in the 
LM yet that we think that we're going to need for 
the surface EVAs several days from now. And - 
consequently, we want you to start to vent the LM 
once again. We're going to drain it out and fill 
it with oxygen again later on today. So, if you 
would please, turn the TUNNEL VENT valve to the 
VENT position "before we start the eye flash. 

02 03 26 01 CDR Okay, Joe. That's in work. 

02 03 26 Olt CC Okay. 

02 03 26 16 CDR Okay, Houston. And we'll take a couple of minutes 

here and run a hatch- integrity check and make sure 
it's all fixed up, and we'll "be with you in a'bout 5. 

02 03 26 23 CC Roger, Dave. Sounds good. 



02 03 36 01 CDR 



Okay, Houston; 15- The TUNNEL VENT ... pretty good, 
so we can go ahead and start the experiment.

a few reminders on the experiment here , if you ' d 
like them. 

02 03 36 IT CDR Okay. Go ahead. 

02 03 36 18 CC Roger. We're just interested - in primarily a 

mark from each of the three of you when you notice 
a - a flash. And then, you might indicate who it 
is calling it out and then a description, as you 
see it: position, color, et cetera, et cetera. 
And - if - any - if another one of you notices one 
in the meantime during the description, call mark, 
and that one then takes precedent [sic]. Over. 

02 03 36 5U CDR Okay. That's about the way we talked it over, Joe, 

We're aJ.1 set. Theink you.

you xinderstood that we'd also prefer the mark on

Okay, Houston. We've got 60 minutes up here. 
How's your clock look? 

Dave. We're coming up on 60 minutes here too. And 
I've - I think that's certainly an adequate period. 
A couple of quick questions, though. Could you de- 
scribe for us briefly your positions in the space- 
craft during this time? 



02 OU 33 15 CDR Okay. We've got it - severail comments for you, Joe. 

Let us un - uncouple here, and we'll talk to you 
for a while about this. 



02 Oh 33 23 CC Roger. 

02 Oh 33 hi CDR Okay. Houston, 15. I guess - we realize the in- 

terest behind this and the significance of the 
thing and - and we'll each try and describe what 
we saw in the way of the flashes. And I think - 
because of the randomnum - randomness of the flashes, 
it was probably better to let us go ahead and work 
out the events on the DSE. And I think, also, 
you'll find on the DSE, when you review the tape, 
that we've come up with a little scheme to give you 
some quantitative data, which may or not- may not 
be the best. And if you have any suggestions on 
future tests or how we can make it a little better 
for you, we'd be glad to hear that. As to our po- 
sitions in the spacecraft, we're in our launch - 
regular and launch positions; I'm in the left, and 
Al's in the center, and Jim's in the right. Do 
you still copy?

02 Ok 3h 35 CC Roger, Dave. Loud and clear. 

02 Ok 3k kl CDR Okay, I guess - as far as my impressions, I would 

say 90 percent of what I'd call a point source of 
light. And to give you perhaps an analogy, you 
might picture yourself sitting high in the stands 
of the - of the Ice Capades with the arena darkened 
and seme single figure on the - on the ice, like 
Peggy Fleming, doing a nice thing. And you look 
across at the other side of the - the dark arena 
and somehody shoots a flashbulb out of their 
Instamatic or something, and that would be what 
I'd call a - a typical flash of intensity 5 on 
a scale 1 to 5» and we tried to sort these out 
relative to their intensities. And that - that 
would be my impression of 90 percent of what I saw. 

02 01+ 35 31+ CC Roger. 

02 Ok 35 kO CDR Okay, let Al give you his impressions. 

02 Oil 35 k6 CMP Okay, Joe. I guess I didn't see the same thing 

that Dave did - and - talking about the intensity, 
I guess that's a very subjective thing. But I 
guess the analogy with the flashbulb . . . was very 
good for the brighter intensities, and it seems 
like there was - there was one flash maybe that 
was of . . . an intensity in the majority of the . . . 

02 Ok 36 07 CC Hey, Al - Stand - Al, stand by. Stand by. 

02 OU 36 13 CC Al, we're starting to lose you because we're 

changing our OMNIs now. Could you stand by a 
second, and I'll give you a call back? 

02 01+ 36 21 CMP Okay, Joe. 

02 Ol+ 37 1+5 CC 15, while you're standing by waiting for the OMNI 

to come around where we can read you more clearly 

- Dave, that was a very, very nice description of 
the flashes. Of course, we're very pleased with 
the - apparently, the intensity values that you 
put on the — on the BSE. And I think our coram 

- comm is starting to improve here, Al, so I'll 
be standing by for your continued description. 



Tape 35/2 
Page 11+8 



02 01*38 17 CMP Okay, Joe. I guess in addition to - to vhafs 

been said already, most of the light flashes seen 
to be of the order of flashcubes or maybe star- 
bursts that you've seen in the summertime. I saw 
very few streaks or radial paths of light. They 
all seem to be Just point sources of light, and 
- and I guess that's really about all I've got to 
add, Joe; I'll _ i»il see if Jim's got something. 

02 01+ 38 55 CC Roger. 

02 01+ 38 59 MP Joe, I just have one comment, ... that's on the 

tape. And that is, just after the timing ... 
ended, we were taking - about to take our masks 
off, I had one - very brilliant streak. ... - -

02 01+ 39 16 MP - .... at 9 o'clock - - 

02 0l+ 39 18 CC Jim, stand by a second. Our comm's starting to 

drop out again, and it may be a partial problem 
with your microphone position. Stand by just a 
second though, please. 

02 01+ 1+0 25 CC Okay, Jim. We have comm again. Proceed on. 

02 01+ UO 32 LMP Roger. I wanted to comment on one brilliant streak 

that I had just after the timing period had ended, 
and I was about - I was in the process of taking 
the mask off, and there was a brilliant streak, 
intensity 5, that went from the 9 o'clock position 
- through 12 o'clock - and out the 3 o'clock. 

02 01+ 1+0 55 CC Roger, Jim. We copy that. And could you tell us 

which eye that one was in? 

02 01+ i+1 05 LMP Well, it seemed like it went from the left eye to 

the right eye. 

02 0l+ 1+1 10 CC Okay; very interesting. Endeavour, the principal 

investigators on this, Dick Benson and Larry Pinsky, 
have followed it closely and are quite pleased, I 
think, with the data you've given us, they'll be 
looking at the DSE information in detail and may 
have a - some definite procedure changes to give 
to you later, based on the information you've 
given us so far. And I guess as far as we're 
concerned, we have no more questions. 



Tape 35/3 
Page ll*9 



02 Oi+ 1+1 kl CDR Okay; fine, Joe. We'll te standing -fay and I - I 

guess another that - that you've picked up - 
interesting thing, is that the - the flashes are 
quite easily located relative to either eye or 
the position within either eye, which I think we 
found rather interesting. 

02 Ok h2 00 CC That's remarkable, Dave. Right; thank you.

looking for - your starting to charge hattery B,

comment that - in discussing that - that last one, 
why, Jim didn't quite have that impression of 
localization within each eye, although Al and I 
both do.

02 Ok k6 19 CC Roger. In the left-hand side of the Flight Plan 

there, the "Lift-off time (if required)." Note 
that it is not required in this case so we don't 
have to worry about that. The - second change - 
is possibly not a change: at 60 hours, 6 0 hours 
I wanted to doublecheck your readback of the addi 
tion which I gave to you earlier. And it should 
read, at 60 hours: "PM CAMERA SELF TEST off " 
and "MAP CAMERA ON, to OFF." Wanted to double- 
check that last step.

02 06 25 30 CC Roger, Dave. As luck would have it, we lost our 

comm joist as we got the DELTA-P number from you. 
We copied 1.9. Verify that for us, please. And, 
also, would you make sure that the valve is still 
in the VENT position. 

02 06 25 ^9 CDR Roger. I cheeked that. It's LM TUNNEL VENT and 

it's, well - 1.9 to 2 - pretty close. 

02 06 26 01 CC Okay, Dave. Thank you. Just leave it in that 

position. 

02 06 26 07 CDR Roger. 

02 06 27 33 CC 15, this is Houston. We have a further question 

about the LM TUNNEL VENT valve.

02 06 27 hh CDR Okay; go ahead, Joe. 

02 06 27 h6 CC Roger, Dave. We should have had a much greater 

drop in pressure - during the - the time between 
these two readings. We want to confirm that you 
went to the DELTA-P position to read the meter thi 
second time. Over. 

02 06 28 08 CDR Oh, no. I thought you just wanted the reading in 

the LM position. 

02 06 28 13 CC Wo, sir. Apparently we have to go over to DELTA-P 

get a reading, and then go - return to the VENT 
position. 

02 06 28 22 CDR Yes, that's absolutely correct, Joe, Thank you. 

We'll do that. 

02 06 29 58 CDR Okay. In the LM/CM DELTA-P - it's 2.9, and then 

hack to LM TUMHEL VEWT is 3.5. 

02 06 30 10 CC Okay, Dave. We copy that. Sounds so much better. 

02 06 30 15 CDR Yes, it sure does, doesn't it. 

02 07 02 36 LMP Houston, this is 15. 

02 07 02 kO CC Roger, 15; go ahead. 

02 07 02 k5 LMP Joe, I understand you have another change to the 

Activation Checklist. 

02 07 02 kg CC Roger, Jim, I had to change Echo for you. I'm 

up to change Foxtrot already, if you're ready to 
copy. 

02 07 02 57 LMP I'm ready to copy, Joe. 

02 07 03 00 CC Okay. Nothing veiy profound here. It - it has to 

do with the LM housekeeping cleaning procedures I 
read to you at 57 plus 1+5. And the procedures 
which I read were basically a cleaning of vacuum 
cabin fan filter. And it involved unsnapping a 
netting around the cabin fan filter, running the 
vacuum cleaner over it, and finally replacing that 
netting. And we've had second thoughts about that 
entire procedure down here - mainly, because the 



Tape 36/3 
Page 155 



netting is in too cramped an axea to get to com- 
fortably - it takes a long time to take the netting 
off and replace it, and the - the procedure is, 
actually, not too effective, anyway. So - we wajit 
you to delete this entire step, and I have two more 
to add instead of this particular step at 57 plus 
U5. Am I clear so far? 

02 07 oh 15 IMP Ah, yes, you're clear so far. Do you still want 

us to turn the cabin fan on? 

02 07 ok 21 CC Roger, Jim. In fact, the procedure now reads like 

this. Before you "begin the LM Activation Checklist 
and you're entering the LM, we want you to vacu\im 
all the LM accessible areas such as Velcro, places 
like that, where dirt and particularly glass parti- 
cles have accumulated. Then, when you've cleaned 
it to yoiir satisfaction, tape the vacuim cleaner 
to the engine cover. Let it r\m while you'r^ do- 
ing the rest of the housekeeping activities. Over. 

02 07 05 11 LMP Okay; I imderstand, Joe. 

02 07 05 13 CC Okay, Jim. And then, finally when you're through 

with the housekeeping activities, clean the vacuum 
cleaner inlet screen with sticky tape. We think 
you'll probably find there are glass particles 
there which you can remove conveniently with the 
sticky tape. 

02 07 05 38 LMP Okay; I copy. 

02 07 05 k2 CC Okay, Jim. That's all I had for you, really. 

02 07 07 15 LMP Joe, this is 15 again. 

02 07 07 17 CC Go ahead. 

02 07 07 20 LMP Roger. Did you confirm that you still want us to 

turn the cabin fan on? 

02 07 07 26 CC That's correct. We - we confirm that. We want 

the cabin fan turned on. 

02 07 07 36 LMP Okay. And assiime if we - if we should see any 

glass on the cabin fan filter, then I suppose we 
should try to get down there with tape and clean 
it off. 



Tape 36/1* 
Page 156 

02 07 0? 50 CC Roger, Jim. That's right. It Just - we do not 

now want you to unsnap the netting around that 
cahin fan filter, in spite of what we told you 
earlier. It still might he possible to clean that 
area with sticky tape - without unsnapping the net- 
ting, though. 

02 07 08 13 LMP Okay; I understand. 

02 07 08 17 CC Basically, - I know you understand. We - we just 

want as much of the glass in the LM cleaned up as 
you can find. 

02 07 08 39 IMP Okay. I think we cleaned it up pretty well yester- 

day, hut we'll do it again. 

02 07 08 33 CC Roger. Just look aroiond. It may not take much at 

all to take it.

you've got some HIGH GAIN angles for us. 

02 07 21 28 CC Stand by on the HIGH GAIN angles . 

02 07 21 1+7 CC Roger, 15. Your HIGH GAIN angles are PITCH, 

minus 75; YAW, plus 36. 

02 07 21 59 CDR Okay; understand. PITCH, minus 75; and YAW. 

plus 31+6 [sic].

02 07 22 06 CC Plus 36. Affirmative. 

02 07 22 19 CDR Okay; tell you what, Houston, we'll go back to 

50 degrees roll and pick up the UV for you ... up 
here.

02 07 22 5I+ CC Roger. We got your torquing angles. Thank you. 

And they say down here that you don't need to roll 
at the present time. We'd Just as soon save the 
propellant . 

02 07 23 06 CDR Well, we'll pick it up at the 50-degree mark, when 

we come around. 

02 07 23 11 CC Okay; that'll be fine. 

02 07 25 00 LMP Okay, Houston. We've got you on the high gain now, 

and we'll check our circuit breakers, be ready to 
cycle the cameras when you're ready. 

02 07 25 10 CC We copy, 15. 

02 07 26 U7 CDR Okay, Houston; 15- If you've got telemetry, we'll 

cycle the film on your cue. 

02 07 26 56 CC Roger. Stajid by, 15. 

02 07 27 01 LMP Roger. 

02 07 27 2h CC 15, this is Houston. Before we cycle the cameras, 

we need to stop PTC. You can either do that im- 
mediately - or else go through the - go through 
the 50-degree roll and use the angles that are in 
your Flight Plan. That's your choice. 

02 07 27 1+3 CDR Oh, we'll Just press on to 50 degrees, ajid stop 

there. We thought you could pick it up on the way 
around. 

02 07 27 U9 CC That will be fine. Thank you. 

02 07 29 12 CDR Houston, Apollo 15. 

02 07 29 lit CC 15, this is Hoioston. Go ahead. 



Tape 36/6 
Page 158 

02 07 29 18 CDR Okay. I'm taking a look at our attitude for the 

UV photos. We see we need a ROLL of 153, and 
your update today gave us a roll of 050 degrees. 
And, it seems like ve proha'bly ought to stop the 
roll at 153, and Just skip that 050-degree atti- 
tude so we can save the maneuver. 

02 07 29 1+8 CC 15. The high gain won't be available to us at the 

angle 153. 

02 07 30 00 CDR Okay. 

02 07 30 15 CDR And, Houston, 15- For future reference, I - I 

guess we are to understand that you cannot do the 
camera cycling while we're in PTC, even though you 
have high gain. Is that correct? 

02 07 30 57 CC Dave, there are pros and cons to that. We could 

do it if we finessed it Just right. But since it's 
difficult, and we have to stop rolling anyhow, it's 
better to stop the roll this time. 

02 07 31 12 CDR Well, that - that's true. We were Just trying to 

save you a maneuver. We got to stop the roll and 
start the roll again to get back to another spot. 
But, we'll go that way.

02 10 53 UO CC Al, this is Houston. Cotild we have HIGH GAIN, 

MANUAL and WIDE? 

02 10 53 kg LMP Roger. Stand by. 

02 10 53 53 CC We don't want to bring it up. We simply want to 

select MANUAL and WIDE. 

02 10 5^ 00 LMP Okay; you have it. 

02 10 51+ 02 CC Thank you. 

02 10 57 11 CMP Houston, Apollo I5. 

02 10 57 17 CC 15, this is Houston. 

02 10 57 22 CMP Roger. We're all up on the coram and ready to talk 

about the SPS. 

02 10 57 27 CC Roger, Al. Dick Gordon's here and he's been in- 

volved in hashing all of this out, and I'd like 
to have him read it up to you and argue with you 
about it. 

02 10 57 ho CDR I'll do that, Go ahead, Richard. 

02 10 57 58 MCC Hello , Dave . No argument ; what are you doing way 

out there? 

02 10 58 Oh CDR Oh, we're just sort of checking out the old LM - - 

02 10 58 07 MCC Okay. 

02 10 58 08 CDR - taking a look at the pretty scenery. 

02 10 58 09 MCC * Okay. Listen, we've been, as you might guess, 

been talking a great deal about PUO procedures, 
and we do have some changes to talk to you about 
and if you've got your G&N Dictionary [sic] handy 
and page 5-I where the PUo thrusting goes, I'd 
like to go ahead and go through it and discuss it 
with you. 

02 10 58 31 CDR Okay, let us pull it out, Dick. 



Tape 39/2 
Page 168 

02 10 58 59 CDR Okay. We've got 5-1 out; go. 

02 10 59 03 MCC Okay, Dave. Right below the "Verify the SIM 

powerdown" line there, I'd like for you to insert 
two lines. "Circuit breakers, SPS PILOT VALVES, 
two of them, open, and that should be a "Verify." 

02 10 59 23 CDR Okay. Should be "SPS PILOT VALVES, two, open; 

verify. " 

02 10 59 26 MCC And then the next line would be "Circuit breakers 

EPS, GROUP 5, two of them, closed; verify. " 

02 10 59 36 CDR Okay. "CB EPS, GROUP 5, two, closed; verify." 

02 10 59 hi MCC Okay. Right there in the same column, underneath 

"Test caution and warning lamps," insert "EMS 
FUKCTION, OFF; verify." 

02 10 59 5U CDR Okay. Beneath "Test caution and warning lamps," 

"EMS FUNCTION, OFF; verify." 

02 10 59 58 MCC Roger. Then the next line would be "Circuit 

breakers EMS main A and B, two of them, closed," 

02 11 00 31 CDR Okay. "CB EMS A and B, both, closed." 

02 11 00 3h MCC Okay, Dave. That'll finish up that page. The 

next comment's on page 5-2, where it starts in 
with a TVC check and prep, second line, "Circuit 
breakers SPS 10, vice 12, close." 

02 11 00 52 CDR Okay; understand. "CB SPS 10, vice 12, closed," 

and those are the two PILOT VALVES? 

02 11 00 59 MCC That's affirmative. Okay. Page 5-3 at the 

2-minute point - 58 with 2 minutes in parenthe- 
ses - like for you to scratch the line that says 
^DELTA-V THRUST A par en B. NORMAL" and substitute 
Circuit breaker SPS PILOT VALVES MAIN B, closed." 

02 11 01 31 CDR Okay. "CB SPS PILOT VALVE MAIN B, closed," instead 

of the "DELTA-V THRUST A and B to NORMAL." 

02 11 01 UO MCC Okay. 

02 11 01 52 MCC We got an OMNI - - 



Tape 39/3 
Page 169 



02 11 01 53 CDR Okay. Go ahead; we got it. 

02 11 01 5h MCC - Okay; we got an OMNI switch; just hang on. 

Okay, Dave. The - the next one is on page 5-*+ 
and it ' s an insert , where you get the flashing 99 , 
helow the line that says "PRO at TFI greater than 
0 seconds," insert "DELTA-V THRUST A and B, two 
of them, to NORMAL," and we'll come back and discuss 
that in a minute. 

02 11 Ol* 03 MCC Okay, Dave. Did you get that? DELTA-V THRUST A 

and B, two of them, to NORMAL right after the PRO 
at the flashing 99? 

02 11 oh 12 CDR No, we - we lost you on the comm there, Dick. At 

minus 2 minutes and we verified we scratched the 
DELTA-V THRUST A or B, to NORMAL, and substituted 
CB SPS PILOT VALVE MAIN B, closed. That's the 
last we heard from you. 

02 11 Oi+ 25 MCC Okay. On page 5-^, I was Just talking about that 

line where you get the flashing 99, and the line 
that says "PRO at TFI greater than 0 seconds." 
Under that line, insert "DELTA-V THRUST A and B, 
two of them, to NORMAL, and I'm sure we'll want 
to discuss this in a little bit. 

02 11 OI+ 51 CDR Yes, it sounds like it. Okay. After "Auto igni- 

tion, PRO at TFI greater than 7 - greater than 
0 seconds," insert "DELTA-V THRUST" - Did you 
mean A or E or do you mean A and B? NORMAL? 

02 11 05 05 MCC I mean - I mean at this time A and B, and we'll 

talk about different burns on this very subject 
a little la^er. 

02 11 05 13 CDR Okay. A and B, NORMAL. 

02 11 05 17 MCC Okay. Down in the next paragraph where it's got the 

06 ho and the emergency proced\ires for the flash- 
ing 97 ho for the SPS thrust fail, scratch the 
line that re£;.ds "DELTA-V THRUST B paren A, NORMAL," 
and insert "Circuit breaker SPS PILOT VALVE MAIN A, 
closed. " 

02 11 05 U6 CDR Okay. Stand by 1. 

02 11 05 h8 MCC Okay. 



Tape 



02 11 06 ll+ CDR 



Okay. On the flashing 97, scratch "DELTA-V 
THRUST B paren A, NORMAL," and insert "CB SPS 
PILOT VALVE B, closed." 



02 11 06 25 MCC That was SPS PILOT VALVE MAIN A, closed, 

02 11 06 27 CDR That right? 

02 11 06 29 MCC That was MAIN A, closed. Dave. 



02 11 06 30 CDR 
02 11 06 3T MCC 



Okay, MAIN - Roger. Sorry about that, MAIN A 
closed; right. ' 

Okay. What we're saying - if you don't get an igni- 
tion on B, we want you to go ahead and use A. 



02 11 06 1*3 CDR Okay. 

02 11 06 kk MCC Okay The next change is at 3 seconds. Scratch 

the line that says "DELTA-V THRUST B paren A 
NORMAL/' and insert "Circuit breaker SPS PILOT 
VALVE MAIN A, closed." 

02 11 07 06 CDR Okay. At 3 seconds, scratch "DELTA-V THRUST B 

A, NORMAL," and insert "CBS - CB SPS PILOT VALVE 
MAIN A. closed." 

02 11 07 18 MCC Okay the bottom of the page, this is applica- 

ble to LOI only. And at 6 minutes into the burn 

m!tI^^ "Circuit breakers SPS PILOT VALVE 

MAIN A, open." 

02 11 07 38 CDR Okay. At 6 minutes into the burn, "SPS PILOT VALVE 

MAIN A, open. 

02 11 07 U5 MCC Okay. And then a note there for Jim. At that 

point, we do - we no longer want any PUGS manipu- 
lation for fuel valves. 

02 11 07 57 CDR Okay; understand. No PUGS after 6 minutes. 

02 11 08 02 MCC Okay. We'll talk about the reason for that in a 

second. I've got one more line in your PUo check- 
J-lst, and then we can discuss some things. On 
page 5-5, it's in the cleanup column there, about 
halfway - no, almost to the PRO underneath the 
vaS% * ""^m"^^ "Circuit breakers SPS PITCH 1 and 
;,Vr,i* ^"^e^'* "Circuit breakers SPS PILOT 

VALVE MAIN B, open." 



Tape 39/5 
Page 171 

02 11 08 33 CDR Okay. Beneath "CB SPS PITCH 1, YAW 1, open," 

insert "CB SPS PILOT VALVE MAIN B, open." 

02 11 08 kO MCC Okay. That cleans up the - the checklist items. 

Take the easy one first. And the reason we want 
to - to secure tank A during the LOI burn at 
6 minutes is so we can get a handle on the single 
bank performance, and we anticipate making all of 
the other burns with the good bank, bank B, with 
the exception of TEI. 

02 11 09 09 CDR Okay; that makes sense. 

02 11 09 12 MCC Okay. And I guess the - the other things we might 

talk about just - just briefly is that the proce- 
dures that we just gave to you are for LOI. For 
midcourse k and DOI , we'll use the same procedures, 
but we'll do it on bank B only, single bank burn; 
we'll use the good bank. And we won't do anything 
with the PILOT VALVE for MAIN A or the DELTA-V 
THRUST A. We'll just go ahead and do these pro- 
cedures, but not use bank A at all. 

02 11 09 5h CDR Okay; understand. We'll use dual bank for LOI and 

TEI, and all other burns will be on bank B only, 
with no manipulation of the DELTA-V THRUST A switch. 

02 11 10 Ok MCC Okay. And after we do our LOI and DOI, we should 

have some real good visibility into bank B; and 
for Al's planning, when he's up there by himself 
for the CIRC and plane change binrns, we'll use normal 
procedures. The old procediires DELTA-V THRUST B, 
NORMAL, at T minus 2 minutes, with the exception 

that we wi:a make those burns single bank, and we 
will not a-i- tempt to use bank A. 

02 11 10 3^ CDR Oh, okay. Well, then, we - we've got three groups 

and when Al^ soloes, he's going to use single 
bank B just like he's always done with the circuit 
breakers with CB SPS PILOT VALVE B in at the be- 
ginning of the procedxires. Is that right? 

02 11 10 51 MCC That's correct. And for TEI, the only change we'll 

probably make is the procedure we Just passed. 
We'll probably let bank A - we'll probably leave 
bank A in the burn until we get down to about 
5 seconds to go, and the reason for this - if 



Tape 39/6 
Page 172 



something happens to the banks then, we're within 
our RCS capability for midcourses . 

02 11 11 16 CDR Okay, I guess - Okay; we - we can press on here, 

but we'll probably talk it over with you before 
each burn anyway, too. 

02 11 11 2h CC Yes, I'm sure we will. And I guess the thing to 

talk about now is our reasoning, our thought 
processes on having you proceed at 5 seconds, and 
then having Al throw on both the DELTA-V THRUST 
switches right after that. And let rae go through 
it, and let you think about it then. The reason 
we want to do that now, even though we do have a 
great deal of confidence in bank B, but the 3PS 
ENGINE THRUST light - we have no visibility into 
that system as long as that light is on. And, if 
for some reason, since we do have this suspect 
system here in A, we don't want to take the 
chance with B. And when that thing fires off, 
we want you to be on a good guidance. You won't 
have to do anything as far as yotir guidance is 
concerned. You can continue the biirn, and press 
on even tho-jgh it - it may have ignited prematurely. 
It does require procedure change, and I think you 
and Al think about how you might handle this, and - 
and come back to us. But those are the reasons 
we did waht to tiarn either DELTA-V THRUST on 
earlier than the point where you'll get good G&N- 
guided burns. 

02 11 12 38 CDR Okay. That sounds like you've been doing some good 

deep thinking on it all. That fits pretty well, 
Dick. 

02 11 12 k6 MCC Okay, Dave. We'll let you guys think about those - 

Hang on. 

02 11 Ik 19 MCC 15, Houston. 

02 11 ll+ 36 MCC 15, Houston. 

02 11 15 38 MCC 15. Houston. 

02 11 15 k2 CDR Okay. We got signal strength back, also, Dick. 

Go eihead. 



Tape 39/7 
Page 173 

02 11 15 h3 MCC Okay, Dave. I guess we might talk about MCC h Just 

a little tit. We haven't really gone into this - - 

02 11 15 52 CDR Okay. 

02 11 15 53 MCC - - too deeply. 

02 11 15 5U MCC We haven't gone into MCC k too deeply yet. Right 

now, it looks like it's a DELTA -V of about oh, 
U.2, and our intentions are at this moment to make 
that single bank biirn with bank Bravo. And if 
something happens there, we're looking at possibly 
finishing that up with - with RCS. But we're not 
definite on that, and just wanted you to kind of 
have a feel for it. 

02 11 l6 26 CDR Okay; that makes sense. I guess we've got one 

point here, and looking at the postignition sequence 
on the LOI bvirn. In order to monitor start tran- 
sients and retain AI'b capability to take over in 
case we have a gimbaJ. hardover at start or something 
like that , perhaps it might be better to push that 
circuit breaker, the SPS PILOT VALVE MAIN A, 
closed, as soon as we get ignition. And then that 
would enable Al to get back over in the THC in case 
he's got a problem there. How about that? 

02 11 IT Oh MCC Okay. We did discuss that a little bit down here 

about thalp time. We felt that we'd like to have 
the - the engines stable out - stabilize out to 
guidance sjid the engine on bank B before he even 
goes over and tries to get that PILOT VALVE cir- 
cuit breaker in. That will give us visibility on - 
on the D6E dump on how bank B is performing. 

02 11 IT 30 CDR Okay, then. Why don't we move it down some time 

past 3 seconds, a little later. How would that 
fit you? 

02 11 IT 36 MCC Well, we discussed that one, too, and 5 seconds 

was used. What would you like? 

02 11 IT kk CDR Well, 5 seconds sounds a tad better than 3, and it 

gives - gives us a chance to get stable in here , 
and gives Al a chance to take a look at what kind 
of start transients we've got. 



Tape 39/8 
Page 17^4 



11 17 58 MCC Okay Dave, I guess our discussion around here - 

We had proposed 5 at one time, and it was a chLge 
to your normal procedures of putting the other 
bank on, so I guess it's really your choice in this 
regard; 5 seconds is Just as good as 3. 

02 11 18 .0 CBH .es U.us.ter) Al made the point that 

It s all changed anyvay, because normally I brine 
on bank - the second bank in 3 seconds, Ld he ^ 

oftL i^I? r "^'^ concentrating 

on the start transients and everything. So it's

02 11 18 43 MCC Okay; that sounds good to us. Yes, Dave; the

that. If you really feel like you need it.

feels uncomfortable about the start transients and

Just a quick note on the - on the circuit breaker 



on the illumination, and then a procedure that 
might clarify a couple of things for us. First 
of all, there's a - a number of numeric and 
electroluminescent lights that are out , but we 
won't go into all of that. The main thing is the 
panel 122 DSKY down there. The - As far as we can 
see at the moment, there is some possibility that 
we still have illumination on your status lights 
on that PSKY, and if we could go through a small 
procedxire here, we may find out whether or not 
there will be illumination on this. Stand by. 

02 11 35 27 CC 15, this is Houston, Are you reading? 

02 11 36 13 CC 15, this is Houston. 

02 11 37 58 CC 15, thi s is Houston. 

02 11 38 09 CDR Go ahead, Karl. 

02 11 38 11 CC Right. Back to our lighting circuit breaker. 

Let me emphasize two main points to start with. 
I guess under no circimistances do we want to close 
that circuit breaker. And a second - problem is 
a - a - a second point is that we don't want to 
change the INTEGRAL LIGHTING, or the NUMERICS 
lighting rheostats on panel 100. Let's leave them 
just as they are. And then there's the - there is 
a possibility due to the fact that there is a very 



'I'apo -^y/io 



low amperage shunt going aroimd that circuit 
breaker, there is a possibility that we do have 
lights on the DSKY status lights; that is, the 
UP-LINK ACTIVITY lights, et cetera. And if we can 
go through a quick procediare here, we'll find out 
whether or not we do have lights there. Shall we 
go ahead? 

02 11 39 Ih cm Okay. Go ahead, Karl; we'll take a look at it. 

02 11 39 IT CC Okay. First of all, on panel 100, again making 

sure that we do not change the NUMERICS and INTEGRAL 
lighting switches, can you tell us the position of 
those two switches, those two - rheostats? 

02 11 39 3h CDR Okay. We'll tape them into position they are right 

now. 

02 11 kO 19 CDR Houston, 15, 

02 11 1+0 20 CC Go ahead. 15, this is Houston. Go ahead. 

02 11 1+0 1|3 CDR Okay, Houston. We Just did a little checkout for 

your LEB DSKY, and the KEY RELEASE light doesn't 
work - for one - does not work. 

02 11 1|0 56 CC Roger. I guess you are a couple of steps ahead of 

us there. Can you tell us the position of - of the 
NUMERICS knob over on panel 100? 

02 11 1+1 09 CDR About 2 o'clock. 

02 11 1+1 18 CC Roger. I guess that's - that's one of our weak 

points. If - if that switch had - if that knob had 
been over close to fvai BRIGHT, we had some chance 
of getting enough energy into those lights to make 
them work, but in that position, that's probably 
not possible. And we should leave things as they 
are. 

02 11 Ul 39 CDR Well - well, I - I'm not sure those INTEGRAL 

lighting rheostats have not been moved since the 
circuit breaker popped. I guess if you want to, 
we coiild run it over to full BRIGHT, or I guess 
you probably prefer to leave it as it is, and if 
so, we'll give up on the status lights. 

02 11 1+2 08 CC The word at the present time is let's leave them 

Just as they are, Dave. 



Tape 39/11 
Page ITT 



02 11 U2 13 CDR Okay. We'll put a piece of tape across so that 

we don't accidentally run into them. 

02 11 1+2 20 CC Okay. 

02 11 1*3 05 CC That's all we have on that subject, 15 . You 

probably know as well as we what lights you're 
missing up there. We could give you a list if 
you would like. 

02 11 k3 IT CDR Oh, no. We've got a good handle on it, Karl. 

Thank you. 

02 11 1*3 21 CC Roger. 

02 11 kQ 02 CC 15, this is Houston. 

02 11 1*8 08 CDR Roger. Go ahead. 

02 11 1*8 10 CC I've got one small comment for you, and then a 

small update to the Flight Plan. First of all, 
they've init - they've gone through a fairly 
thorough test on the range rate meter and how it 
operates iinder those pressures and in that pure 
oxygen aT;moBphere, and so far as we can see at the 
present time, there is no problem whatever in its 
operation, but we'll continue that test. In the 
Flight Plan at 60 hours on the - on the SIM bay 
procedure to get some data from the cameras there, 
I have a small change, if you have the Flight Plan 
out . 

02 11 1*8 53 CDR Go ahead, Karl. 

02 11 U8 56 CC Right. That procedure should go in this order. 

First, the g-BABD AUX, TV to SCIENCE, as is 
already there. Then the PAN CAMERA POWER, on for 
5 minutes, and then off. After the POWER goes off, 
wait for a flSFN cue because we want to pick up some 
data in that - in that state as well. After you 
get a MSFN cue, then we go to the PAN CAMERA, SELF 
TEST-off , the MAPPING CAMERA, ON switch to OFF, 
and then the S-BAND AUXILIARY, TV-off, in that' 
order. And we're going to need the HIGH GAIN 
ANTENNA for this Job. And we're going to have a 
PITCH, minus 30; and a YAW, of 90, and we're going 
to have to give you cue as to when to start this, 
so that everything will be lined up right.

02 13 07 ^5 CC Looks like a very quite night tonight. About the 

only question we've got for you at the present 
time is your assessment of the glass cleanup. How 
did It go? 

02 13 08 01 CDR Well, we got a - a few more pieces just by looking 

around over there. Some of the smaller like - oh, 
I guess the largest piece we found was about a 
centimeter or so, and the vacuum cleaner picked 
up a bunch of small chips. I guess - In total, 
we may have 60 - 70 percent of the portion that 
broke, and I think we've really picked up all that 
is practical at this stage. 

02 13 08 29 CC Roger. Any special places this stuff seems to 

collect that you can tell? 

02 13 08 39 CDR I think, initially, we've found most of it was - 

up near the COAS mount and behind the panel on 
the left side - near - near the forward part of 
the window. We found several - several larger 
pieces there and also one large piece just above 
the data file, which was about an inch long or so. 
The small pieces seem to have been drifting all 
about . 

02 13 09 07 CC Roger. 

02 13 09 25 CC And 15, we didn't forget your state vector. It's 

just that the one you got on board is very good. 
We don't need - we feel we don't need an update. 

02 13 09 36 CDR Okay. 

02 13 09 38 CC Just polishing off a hamburger and french fries 

down here. What's on the menu up there tonight? 

02 13 09 hC CDR Oh, stand by a minute, Karl. 

02 13 12 36 CDR Hey, Houston, 15. 

02 13 12 1+0 CC 15, go ahead. 

02 13 12 kk CDR Okay, we're just getting ready to do some chlorina- 

tlon here, and we find we've got a leak around the 
chlorine port - with a cap on it - seems to be 
leaking water. And you might take a look at that 



Tape kO/3 
Page 183 



real quick and see if you can come up with any 
ideas on the thing. The cap is on, and Jim was 
just getting ready to take the cap off and noticed 
a little water; and, in trying to clean it up, it 
seems like we're accumulating a fair size - fair 
amount of water right now, right around the cap. 

02 13 13 13 CC Can you give an - give us an estimate of how many 

drips per second it is? 

02 13 13 20 Ii«IP Yes, it's a - it's a pretty good flow right now. 

Drips per second, it's hard to measure; it's a 
whole ball of water right around that valve right 
now. 



02 13 13 29 CC Roger - 

02 13 13 37 CDR What we need is a check valve that we can close 

or get to, to isolate that port, if we could get 
one • 



02 13 13 ^3 CC Dave, I - I had a problem when I chlorinated on 

launch day. And, when I first took the valve off, 
I had about what you've got - quite a strong flow. 
The cap - the cap stops it from flowing when you 
put it back on, and after I chlorinated, the flow 
decreased down to a very slow drip, say once a 
minute . 

02 13 ik 05 CDR This is a big riin, Karl, and the cap is on tight, 

and it - you can almost feel something flowing 
beneath the cap. 

02 13 1^ ih CC Okay, stand by. Lots of people thinking down 

here now. 

02 13 1^ 17 CDR Okay. 

02 13 15 25 LMP Houston, 15 . It seems to be leaicing from behind 

that panel there , right behind where the waste 
tank servicing valve is, and the potable tank 
inlet - and it's accumulating at a pretty good 
rate . 



02 13 15 38 CC 



We copy .

02 13 IT 25 CDR Hey, Houston; 15. Got any suggestions yet? We 

need to isolate this thing pretty quick. 

02 13 17 31 CC In - just a minute. 

02 13 17 5i+ CC What was - 

02 13 18 08 CC 15, this is Houston. Our recommendation is that 

on 351, you turn the WATER & GLYCOL TMKS PRESSURE 
REGULATOR, OFF. On 352, turn the POTABLE TANK 
INLET, OFF. 

02 13 18 27 CDR Okay. POTABLE TMK INLET is now CLOSED, and say 

again the other one. 

02 13 18 3^+ CC Up on panel 351, WATER & GLYCOL TANKS PRESSURE 

REGULATOR, OFF. 

02 13 18 51 CDR Okay, WATER & GLYCOL TANKS PRESSURE REGULATOR 

is OFF. 

02 13 19 hi CC 15, Houston, That should - that should have taken 

the pressiire off of the potable water tank; is it 
helping the situation any? 

02 13 19 58 CDR No, it's still leaking, Karl; pretty good rate. 

02 13 20 07 CC Roger; stand hy. 

02 13 22 57 CDR Houston, looks like maybe we ought to start dumping 

out of the waste so we can dump out of the potable 
tanks. It's still leaking and we've got everything 
but the check valve between the potable tank and 
the chlorine nozzle isolated. 

02 13 23 26 CC We copy, Dave. No comments yet. Stand by. 

02 13 25 39 CC 15, Houston. We note the pressure in your tank 

coming down. In the meantime, we suspect that the - 
we suspect that the fitting there on your chlorine 
injector outlet is loose, and we have - we have a 
procedure here for tightening it up. 

02 13 26 0i+ CDR Okay; give it, quick. 



Tape 1+0/5 
Page 185 



02 13 26 06 CC Roger. We need tool number 3 and tool number W 

out of the toolkit. 

02 13 26 li; LMP Okay; 3 and W out of the toolkit. 

02 13 26 17 CC Right; put - put nimber 3 in the tool W ratchet, 

sind insert - sert tool 3 in the hex opening in the 
chlorine injector port. 

02 13 26 28 CDR Okay. That's - that looks like where it's probably 

leaking. 

02 13 26 53 CC And, once we have the nijmber 3 tool in the hex 

opening, it should go in about a quarter of an 
inch to really engage. It also says "Use caution 
when inserting the tool because it comes in contact 
with a rubber diaphragm." 

02 13 27 10 CDR Okay. 

02 13 27 16 CC We've agreed down here it's a good idea to take 

the water gun to fill up a food bag or something 
of that sort. 

02 13 27 2h CDR Okay. 

02 13 27 30 CC Once you've got tool number 3 well engaged in that 

injection port, turn it about a quarter turn. 

02 13 29 55 CDR Okay, Houston. It looks like that did it. 

02 13 29 59 CC Wonderfiil. 

02 13 30 09 CDR Nice to have the quick response you guys have 

down there . 

02 13 30 ik CC Well, you'll never believe it, but after we had 

the leakage on the morning of the 26th, somebody 
sat down and wrote up a special procedure, just 
in case. 

02 13 30 25 CDR Well, that was good thinking because we about had 

a small flood up here . 

02 13 31 51 CC 15, Houston. We're looking now at the best pro- 

cediire for getting the water system operating again. 
In the meantime, we trust you have your hands full 
of water up there . 



Tape 1+0/6 
Page 186 

02 13 32 Ok CDR Yes. All ve have to do now is hang out a few 

towels to dry, but looks like we're in good shape. 

02 13 32 10 CC Very good. 

02 13 33 11 CC 15, Houston. We'd like for you to turn the 

REGULATOR back ON, on panel 351. 

02 13 33 18 CDR Okay. REGULATOR coming back ON. 

0:^ 13 3'i 28 CC 15, Houston. Is everything looking all right on 

the leak now? 

02 13 3h 3h CDR Yes; it looks okay. That fitting there that we 

tightened up went somewhere between - l80 - 270 de- 
grees of turn. And that - that was where the water 
was coming from, and it looks like it's secure now, 

02 13 3k kQ CC We copy. 

02 13 36 37 CMP Hey, Karl, we just ran a little check with our 

slide rule Jiere, and it was something like 
3000 drips per minute. 

02 13 36 k7 CC Okay; glad to hear that good news. I - I guess 

up there you don't get drips, do you; that's an 
interesting fact. 

02 13 36 57 CMP Roger. 

02 13 37 03 CC Okay, Dave. We're ready to open the INLET valve 

to the POTABLE WATER TANK. 

02 13 37 10 CDR Okay; POTAELE WATER INLET coming OPEN. 

02 13 37 15 CC Incidentally, Dick was over at Lurton's and they 

called up to say, "Hey, it's about time you take 
a bath up there. " 

02 13 37 2k CDR Well, we were sort of discussing that a little 

earlier tonight anyway. And, as a result, well, 
I guess we all got cleaned up.

we'll change that one also to "CM 3" instead of 
"CM k," 

I copy.

02 22 36 56 CC Roger. And then over on the other side of the page 

at 8U:U0, again terminator photos. The first one, 
the first line there, QkikO will now read "EL, on," 
and the time will he "T-STAET minus l:Uo," l:Uo. 

02 22 37 22 LMP Okay. I copy. 

02 22 37 25 CC And then at &k'.k2, "-EL, off" will now he at "EL, 

off, parenthesis, T-START." 

02 22 37 ^1 LMP I copy. 

02 22 37 ^2 CC Okay. And we have two general notes. One refers 

to SIM door JETT, and it's a reminder that we verify 
that the Lexan shield is mounted in - window 5, 
with the cardboard shade off, for a photograph of 
the SIM door JETT. At - this is about 7i» hours. 

02 22 38 10 mP Okay. I understand. 

02 22 38 11 CC Okay. And second one is with respect to the optics 

CALs. And I guess we should explain here that - 
people who are wringing their hands down here about 
the fact that we looked at a little hit of a bias 
drift when you guys zeroed the optics the first 
day, and we sent up some procedures yesterday say- 
ing to be carefvil when you are doing it for P23. 
And then everybody else got - decided that we oiight 
to be careful when we did it for other things be- 
sides P23. And so, we have the following procediAres , 
which are, basically, to avoid trunnion rates for 
all optics zeroing, so that we don't get any - pos- 
sible shift on the mirror calibration. And the 
procedures are -wofold. First — I guess you might 
write them down some place — if the OPTICS power 
is off, place ZERO switch OFF before turning the 
optics power on. And then, after the power is on, 
drive the optics manually to a trunnion of less 
than 10 degrees before placing the ZERO switch on. 
Over. 

02 22 39 26 IMP Okay, Bob. If OPTICS power off, then OPTICS ZERO 

switch, ZERO? 

02 22 39 39 CC Roger. It really is, if OPTICS power off, place 

the ZERO switch to OFF before turning the optics 
power on. 



Tape 1+6/5 
Page 197 



02 22 k2 l6 CC 15, Houston again. 

02 22 it2 Itl CC 15, Houston. 

02 22 1+2 1+9 LMP Bob , -would, you read that procedure again? I want 

to make s\ire I have it correct. I have OPTICS 
power off, then OPTICS ZERO switch, ZERO. 

02 22 1+3 oh CC Okay, Jim. The thing is, if your optics power is: 

off, we - as it will be like this morning, is OFF-, 
we - as it will be like this morning, and the ZERO 
switch is already on, as it probably is this mornr 
ing, we want you to place the ZERO switch to OFF 
before you turn the OPTICS power on, because, 
otherwise, it will then automatically zero without 
you having control over it . Do you understand? 

02 22 1*3 28 LMP Okay. We understand. 

02 22 1+3 30 CC Okay. And - the corollary 

02 22 1+3 33 LMP Read the - read the rest of it after the OP 

02 22 1+3 37 CC Okay. And then after, - Okay; I'll - I'll read it 

through from the beginning again. If OPTICS power 
off, place ZERO switch OFF before turning OPTICS 
power on. Then, drive OPTICS manually to TRUNNION 
less than 10 DEGREES before placing ZERO switch 
ON. Over, 

02 22 1+1+ ll+ LMP Okay. That was after the OPTICs power ON. Drive 

optics until trunnion is less than 10 degrees be- 
fore ZERO switch ON. 

02 22 1+1+ 2l+ CC Roger. And the corollary to that is if the optics 

power is already ON, then we drive the OPTICS 
power manually to a trunnion of less thajn 10 degrees 
before placing the ZERO switch ON. That's the sec- 
ond part. 

02 22 1+1+ 1+2 LMP Okay. We copy. 

02 22 1+1+ 1+1+ CC Okay. And then I have an update to your Contingency 

Checklist, page 1+-3 which pertains to LOI burn rules, 
if you can get that out. 



02 22 1+1+ 58 LMP 



Stand by. 



Tape it6/6 
Page 198 

02 22 kk 59 CC Roger, 

02 22 U6 59' LMP Okay, Bob. I have the Contingency Checklist. 

02 22 1+7 01 CC Okay. I got U - page k-3. 

02 22 U7 09 liMP Stand by. 

02 22 kf 20 LMP Okay; I have k-3. 

02 22 U7 22 CC Okay. And these changes are basically in the 

table there. - We'll start out under the heading 
of "Bumtime." And that first one will be cheuige 
from "00 to 1:36," now, instead of "1:35." So, 
it'll be 1:36 in the first bum time. The second 
line will be "1:36 to 1:57." And the third line 
will be "1:57 to 2:13." And the foiirth line will 
be "2:13 to 3:11." Over. 

02 22 U8 15 LMP Copy. 

02 22 hQ 17 CC Okay, the next one in the second column, "DELTA- Vj^," 

the lines will be 0 to, or "0-640, 6kO-l8k, 781t-900 , 
900-1313." Over. 

02 22 U8 55 IM> I copy. 

02 22 U8 57 CC Okay, and, in the second block, the lower block, 

under the updates for the times and angles, we 
have the folloT^ing readings xmder the "Update" 
column. The GET of LOI ignition is "78:31:3l+.2 ," 
the second time is "79 :01: 3l*-2 ," and the angles 
are "ll+l*, 358, and 68." Over. 



02 22 1+9 1+9 LMP Okay, copied op the update time, "78:31:3l+.2, 

79:01:31+. 2; ll+4, 358, and 68." 

02 22 50 03 CC Roger. And, be advised, this also changes your 

little graph over on the side there. Primarily 
what it does, is to enlarge the mode 130 region 
by about 10 feet per second on either side and it 
changes the "LOI plus 30 abort DELTA-V" line by 
essentially extending it and raising the left-hand 
corner Just a wee bit . We could read up the lines 
too if you want, but I'm not sure you really need 
those. Over.

Jim, this is Houston. Is that a verify on the fact 
that you don't want the update on the graph? Over. 

I think we can do it ourselves. Bob.

Roger. OMI Delta. 

And, 15, we'd like VflDE and MANUAL on HIGH GAIN, 
please. 

Roger. 

Apollo 15, this is Houston. Select OMNI Bravo, 
please. 

OMNI Bravo.

Go ahead, Joe. 

Go ahead, Joe. 

Stand by, Jim. I'll wait until the coram 's a little 
better. 

Hello, 15; this is Houston. 
Go ahead, Joe. 

Good morning, Jim. This is your friendly news 
reporter on duty now. And I wondered if you'd 
be interested in something frcm the local news- 
papers? 

Oh, yes. We certainly would. 

Roger. This is from the MOCR Gold Bugle and 
Taglich ?eitung News. The Administration effort 
to rescue Lockheed Aircraft cleared a major hurdle 
in the Senate yesterday when an amendment to deny 
favored status was rejected 60 to 35- Houston 
unemployment rose to k.l percent in June, an in- 
crease of a full percentage point from May, which 
is the highest in 6 years. And this morning's 
Post reports that the checkout of Falcon went on 
with a few words from Worden and virtually nothing^ 
from the other astronauts. However, I think that's 



Tape 1*7/2 
Page 202 



incorrect, and I enjoyed talking to you very much 
yesterday. In sporting news, Houston dumped 
Philadelphia, 6 to 3, and is now in fourth place, 
10 games behind the Giants. And an interesting 
note from the North. Bart Starr underwent surgery 
yesterday for a bicep tendon transplant and will 
he out of action for at least 12 weeks. And that's 
all from the Daily Zeitung this' morning. 

02 23 kO 5k CDR Thank you, Joe. Enjoyed it.

03 02 03 23 CC Roger. 

03 02 03 29 CDR The - the MAPPING CAMERA is in STANDBY now, hut 

it required a - a change. 

03 02 01+ 00 CDR Okay; Houston, 15 . I - do you want the MAPPING

03 02 Oi+ 06 CC That's affirmative, 15. MAP CAMERA, STANDBY. 

03 02 Oh 13 CDR Okay.

03 02 Ok 1*8 CC That's righ-p , Jim. Per the checklist, the first 

one in step h. 

03 02 Ok 56 LMP Okay. We j,ast wanted to confirm it. 

03 02 01+ 59 CC Roger. Sounds like a good idea. I think we have 

a hug or two in this procedure. 

03 02 05 23 CC Apollo 15, Houston. 

03 02 05 31 CDR Go ahead, Houston. 

03 02 05 3k CC Roger, Dave. We're ready for PAW CAMERA POWER to 

BOOST. On your step 2 there, you are GO for SIM 
door jettison. And we want you to watch the FUEL 
CELL REACTAIW valves after the Jettison, per the 
checklist - just a reminder of that. Over. 

03 02 05 58 CDR Okay; understand. And we are in boost, and we'll 

give you a mark when we blow the door. 

03 02 06 07 CC Roger. And we will be standing by for a

tiimbling . 

03 02 09 26 CC Roger. 

03 02 09 51 CC And, 15, just out of interest, we saw a good 

healthy jolu in our Doppler data down here during 
JETT time. 

03 02 10 02 CDR Gee, that's very interesting because I would say 

that the jolt in here was very minor. 

03 02 10 29 CDR Houston, 15- I guess the consensus would say that 

the - the shock was about one-tenth of the other 
pyros we've seen up to this point. 

03 02 10 k2 CC Roger, Dave. We copy. Can you still see the 

world's largest lens cap out the window?

03 05 25 05 CC 15, this is Houston. Go ahead. 

03 05 25 11 CDR Okay, we've Just made a little mission-rules re- 

view up here, and I have one q_uestion for you - 
relative to the circuit breaker on bank A procedure 
at 6 minutes. Our interpretation of the mission 
rules says that, if we have a bank B ball valve 
close premat^urely , then we would leave that cir- 
cuit breaker closed until shutdown, and close - 
or - or mtil 10 seconds prior to shutdown, using 
that as our good bank rather than closing it in 
6 minutes. And this is in reference to the cue 
card - at t'le bottom where it discusses one ball 
valve closing prematurely. 

03 05 26 06 CC Stand by. 

03 05 26 11 CDR Okay. 

03 05 26 1+6 CDR Houston, 15 . I'll just repeat it once here, maybe 

in simpler terms. If bank B closes prematurely, 
then we'll leave the PILOT VALVE on A closed until 
10 seconds prior to cut-off, instead of at 
6 minutes . 

03 05 27 05 CC Roger. We :opy. 

03 05 27 28 CC 15, Houston ^ ¥e copy your question, and we concur. 

03 05 27 35 CDR Okay, thank you. Everything else I think we have 

squared away. 

03 05 27 kX CC Roger. Milt says we owed you a review before every 

burn. Are you interested in a quick runthrough of 
what happens at LOI? 



Tape 51/2 
Page 216 



03 05 27 53 CDH Sure, why not. 

03 05 27 56 CC Okay. As I have it here, starting at T minus 2 - 

T minus 2 minutes, we close the MA.IH B PILOT VALVE 
circuit breaker. At T minus 5 seconds, we PRO. 
Then, the DELTA-V THRUST A and B switches both go 
to NORMAL. At T plus 5 seconds, we close the 
MAIN A PILOT VALVE circuit breaker; and, at T plus 
6 minutes, assuming nominal burns, we open the 
MAIN A PILOT VALVE circuit breaker; and, after 
that, we avoid PUGS manipulation. And a reminder 
here is - don't forget to ttirn on the DSE because 
we're vitally interested in that single-engine 
burn performance. 

03 05 28 53 CDR Okay, Houston; we're right with you. We've just 

gone through that, and - we understand it. Thank 
you.

03 06 56 25 CDR Hello, Houston. The Endeavour's on station with

03 06 56 58 CDR Okay. I think our trusty pilot has a first for 

you on this one. Burn time was 6 plus 38, igni- 
tion was on time; the residuals were 0, 0, and 0; 
DELTA-V-, minus U.8; the fuel, 33-25, the

03 06 57 37 CDR And it was a very smooth hurn all the way, Karl.

03 06 58 22 CDR And, Houston, after our first few minutes of

03 07 13 3T CC We've just got through with the playback, and 

we've got excellent burn data down here. And, if 
you'll give us ACCEPT, we'll send up a REFSMMAT. 

03 07 13 it7 CDR Okay; you've got POO and ACCEPT. 

03 07 13 52 CC Thank you. 

03 07 13 57 CDR And, Houston. We're over Mare Crisium at the 

present time, and the sights are really striking. 
I guess some of the interesting things we've noted 
is the variation in albedo from white to dark gray 
with many variations of gray in between. And 
many times, this albedo change appears without 
any significant change in topography, other than 
perhaps a - a mountain ridge or a chain or a 
wrinkle ridge or something, but there are many 
vari - variations in the albedo all over the 
STirface. I guess our general consensus is, it's 
gray. We haven't noticed any brown yet, 

03 07 Ih kg CC Excellent. If I'm not mistaken, this is probably 

the first time men have been over Crisimn. 

03 07 Ik 59 CDR I guess that's probably right. 

03 07 15 09 CDR We have everything from the very old subdued 

craters that aj?e almost completely washed out to 
the very bright fresh ones which have interior 
walls of almost pure white. 

03 07 15 2h CC We're lapping it up down here. Keep talking if you 

feel like it. 

03 07 15 37 CDR Another interesting fact that - that we've all 

noticed is that it - it looks like a great desert 
across which we've had a number of dust storms. 
And, in many places, you can see the - the tracks 
or the swirls across the surface which looks like 
a - a great dust storm has been blowing across the 
surface - primarily indicated by the albedo change. 
But all over Crisium, you can see the streaks. 



Tape 52/3 
Page 221 



which obviously are Tram impact at some point or 
another, but the impression we get is that the 
results of a dust storm. 

03 07 l6 12 CC Very interesting; 15 > the computer's yours, 

03 OT l6 27 CDR Say again. 

03 07 l6 29 CC The computer's yours. 

03 07 l6 32 CDR Okay. 

03 07 l6 hk CMP Karl, this is Al. I'd have to say pretty much 

what Dave's been saying. Might be interested to 
know that we're coming up over Pierce right now, 
and just about to hit the west rim of Mare Crisium, 
and kind of looking forward to taking a look at 
Proclus as we get up a little bit closer here. 
There are a couple of craters just to the north - 
northeast corner, and we'll pinpoint those a little 
better for you later. A very, very small crater 
that looks like it's heid some dark material slide 
down into the crater, the eastern wall of the in- 
side of the crater has some very dark material in 
it,- and at - at this S\m angle, it doesn't appear 
that it's shadow. 

03 07 17 32 CC Okay; we copy. 

03 07 17 39 CDR And, you know, as we look at all this after the 

many months we've been studying the Moon and 
learning all the technical features and names and 
everything, why - when you get it all at once, 
it's just absolutely overwhelming. There are so 
many different things down there and such a great 
variety of landforms and stratigraphy and. albedo, 
that ' s it ' s hard for the mental computer to sort 
it all out and give it back to you. I hope over 
the next few days , we can sort of get our minds 
organized and get a little more precise on what 
we're seeing. But I'll tell you, this is abso- 
lutely mind-boggling up here. 

03 07 l8 15 CC Gentlemen, I can well imagine that a foreign planet 

must be a weird thing to see. 

02 07 l8 25 CDR Roger. And we've got Proclus in view right now. 



Tape 32/h 
Page 222 

03 07 l8 28 CC Excellent, Tell us about it if you have a chance. 

03 07 l8 37 CDR Well, the - the rays extending from Proclus are 

very light in color for about - they are very light 
color for about - oh, 2^0 to 260 degrees around, and 
then there's a region of dark mare or albedo. And 
our - our orientation presently with the spacecraft 
is such that we have - we're having a totigh time 
figuring out north and south; and, once we get on 
an orbit track, we'll be able to give you direction 
a little bit better. But the inner walls of 
Proclus are very light in color, alatost white. 
The outer walls - the outer ring has a somewhat 
light gray appearance, and the difference in the - 
the rays is really between a light and a dark gray, 
as distinguished from the inner walls which are 
quite white. The - the wsills exhibit some debris 
on the upper slopes, maybe the upper 30 percent. 
I can see, on one side of the - the crater, some 
large blocks. On another side, I can see what 
appears to be a large slump block or a lax^ge 
slumping of the wall that goes about halfway down 
and takes about - oh, 15 degrees of the rim of the 
crater with it . The floor is very irregular and 
roTigh, almost constsmt gray - medium gray color, 
somewhat darker than the light gray on the outside 
rays and somewhat lighter than the dark gray on 
the - the surface, which does not seem to be 
covered with a ray pattern. There are a few 
ridges on the floor , arcuous ridges , and some 
domes which are quite prominent. And I'm sure 
when Al comes back over here later on and has a 
chance to study it carefully, he can give you 
a - a good acciirate picture. 

03 07 20 55 CC Beautiful. 

03 07 21 36 CC 15, we vovHd like to have TRACK to AUTO on the 

HIGH GAIN. And, for your information, the 
Saturn IVB impact is going to take place in just 
a few minutes. It's going to be a - in a - - 

03 07 21 51 CDR Okay; very good. I wish we were in a 

03 07 21 5** CC Right. It's 2 minutes kO seconds, but it's going 

to be out of your visual range, somewhere around 
the center area of the Moon.

Page 223 



03 07 22 07 CDR Roger. It's too 'bad we won't get to see it. 

We'd already taken a look at the map to see if 
we'd have a chance, hut I guess we'll miss that 
one. 



03 07 23 11 CDR Houston, 15. We're coining up to Serenitatis, and 

it really looks like an oceaji. The landforms , as 
we approach, are very rugged, very highly cratered, 
rounded, and we get to the shoreline and we see a 
few wrinkle ridges that have smoothed out . And 
we can see, on the far side on the horizon, the 
mountains which pick up again on the western side 
of Serenitatis. 



03 07 23 1+3 CC Roger, 15. 

03 07 23 k6 CMP Okay, Karl. We're coming up over Serenitatis now. 

We're almost over Le Monnier at the present time, 
and we can see the Littrow area just out in front 
of us. And it is, in fact, ahout three different 
shades. You can see the - in the upland area, and 
particularly what looks like down In the valleys, a 
darker color, and It does look like it's a light 
powdering- or dusting-over of the entire area. 
And then, as you get out further into Mare 
Serenitatis, there's another layering which is a 
little bit lighter in color. And then, out at the 
last edge of the wrinkle ridge, out beyond that 
is the last layer, and the rest of Serenitatis looks 
fairly - fairly light in color. So I'd say that 
the - the - the centeral - central part of 
Serenitatis is light, out beyond the first wrinkle 
ridge is a darker layering, and we're not up close 
eno\igh to see what it is yet, and then as you get 
up into the highlands around Le Monnier and Littrow 
area Itself, there's what - what appears to be 
a - a light dusting of dark material, and it cer- 
tainly looks volcanic from here. Off to - to the 
left of that to the south, we can pick up Sulpicius 
Callus pretty clearly right now. 



03 07 25 08 CC 
03 07 25 18 CMP 



Roger, Al. Sounds like you're seeing a marvelous 
amount of detail up there. 



Well, after - after the king's training, it's 
almost like I've been here before. 



Tape 52/6 
Page 22U 

03 OT 25 23 CC You can't help yoiorself, can you? 

03 07 25 28 CDR And, Karl, we're approaching the Apennine 

Mountains, and that is indeed a spectacular view. 

03 OT 25 3^ CC Roger - - 

03 07 25 35 CMP Sure is, Karl. No question about those mountains 

being there and where we're at with them. 

03 07 25 hi CC They stand up on your horizon, do they? 

03 07 25 52 CMP Yes; tremendous relief as we approach the moxin- 

tain, Karl. 

03 07 25 58 CC Roger. And, for your information, gentlemen, 

we're getting a good seismic signal from the 
impact of the Saturn IVB. 

03 07 26 50 CC 15, this is Houston. There is no update required 

on your T - on your TEI-l^ pad. 

03 07 26 59 CDR Okay, Houstoa; understand. Houston, as we cross 

out of Serenitatls into the Apennines, why, it's 
Just - u&real. You loiow, those are very poor 
descriptive terto, but the - the movaitains jut 
up out of the OGiean here in great relief. I'm 
sure the guys who^ve been here before can probably 
sit down over a cup of coffee and tell you. But 
the relief is really pervasive. 

03 07 27 35 CC You're the first man to fly over this mountain 

range, Dave, I guess pretty soon you're going to 
be over the - over the landing site, aren't you? 

03 07 27 i+8 CDR Roger. But I'm afraid it'll be dark today. 

03 07 27 51 CC That's right. 

03 07 27 57 CMP Karl, this is Al again. Looking down into the 

Sulpicius Callus area, looking at some of the 
wrinkle ridges and some of the rilles - the 
arcuate rilles down there, I can make out some 
distinct color patterns that seem to run parallel 
to the arcToate rilles - and along the wrinkle 
ridges, and there is a very subtle darker color, 
again almost as if it was - some kind of cinder 
fallout along the ridges and along some of the 
rilles. 



Tape 52/7 
Page 225 



03 07 28 38 CC Roger, Al. 

03 07 29 00 CDR And, Houston, we're coming up here on the termina- 

tor and the area I guess we call Crackled Hills 
really looks like crackled hills. If you distin- 
gTiish between the mountains, which are very promi- 
nent and smooth, the surface between the first 
small mountain range and the - what is now the 
terminator, is relatively flat with a very rough 
texture - very irregular, lower, crackled hills. 

03 07 29 35 CC We copy, Dave. 

03 07 29 U7 CDR Jim's - Jim calls it a gun-metal gray, and that's 

a very good term, I think, for the color that we're 
seeing now. And as we approach the terminator, of 
course, the relief stands out even more. The 
shadows are getting much longer, and the peaks of 
the mountains, as they're silhouetted against the - 
the Crackled Hills, seem to have a - a diffuse 
shadow at the top. The - the shadow, as it goes 
from the base of the moimtain to its peak, is 
very sharp. And around the top of the mountain, 
it becomes more diffuse, not - not quite as sharp 
and begins to blend in with the - the surface on 
which it's being cast. 

03 07 30 hi CC Roger, Dave. Sounds very interesting. 

03 07 32 31+ CDR Houston, we're trying to get oriented here so we 

can perhaps pick out some of the features near 
the landing site. There's quite a bit of shadow 
now, but we have Aristillus and Autolycus very 
clearly. And with a low Sun angle, the surface 
between those two large craters and the rim of 
Imbrium - the eastern rim of Imbrium is very 
rooigh, quite a bit of debris, and it looks like 
it probably came out of the two craters. I be- 
lieve we can see Hadley C, Just barely on the 
shadows . 

03 07 33 21 CC Roger, 15. We copy that. Did I understand that 

the rim of Autolycus is standing up in the 
sunlight? 

03 07 33 31 CDR Yes, that's true. Aristillus and Autolycus both 

have their eastern rims exposed to the sunlight, 
and we get a pretty good look at the elevation on 



Tape 52/8 
Page 226 



the rim. And Autolycus , to its northeastern side, 
seems to have a - a saddle or somevhat depressed 
rim, and as you come aro\md to the west - the 
eastern side of Aristillus, it seems to be rela- 
tively level or horizontal, with a few subtle 
saddles and depressions. Autolycus appears to 
have a - a relatively horizontal or - or even rim 
all the way around, and we can see s\inlight on the 
northwestern side of Autolycus on the rim, Just 
barely a tick of it. 

03 07 3h 28 CC Roger. It sounds like a fantastic view. 

03 07 3h 35 CMP It really is. 

03 07 3h h2 MCC You guys have enough to keep you busy for a few 

days then? 

03 07 3h U8 CDR Hey, Dick, we got enoujgh to keep us busy for 

months and months and months, as you well know. 

03 07 35 05 CDR The outer rima of Aristillus and Autolycus seem 

to be quite heavily cratered and rough; and Aris- 
tillus, on its east -northeastern side, seems to 
have a couple of benches on the outer rim as it 
goes' down to the surface, and their - the shadows 
are - are exposed quite well. 

03 07 35 3h MCC Roger, Dave. 

03 07 36 11 CDR Houston, just north of Conon, there's a - a great 

depression in the mountains - a low part of the 
mountains. In the - The western side of the 
mountains is exposed to the sunlight, and this 
reflects back into the shadow part of the mountains 
which - the base - basin just north of Conon there 
is really shadowed by the eastern mountain range; 
but the reflectivity back from the - the mountains 
exposed to the sunlight illuminates the - the 
shadowed area to where we can pick out craters and 
ridges and various other topographic features. 
It's - it's really quite interesting. As a matter 
of fact. Just to the - the inner walls or the in- 
ner basin of Conon itself is illuminated by its 
own reflectivity on its western wall. 

03 07 37 1^ CC Roger. That sounds like a fascinating illumina- 

tion. Do - do you have any inclination that you're 



Tape 52/9 
Page 227 



going to be able to see the dark side of the Moon 
■with earthlight on it? 

03 OT 37 30 CDR Well, we can just barely see subtle features now, 

I think. We can see the horizon quite clearly, 

03 07 37 U3 CC Roger. When you get dark-adapted, it may be that 

things will come through pretty well. 



03 07 37 51 CDR Roger. 

03 07 ^+8 27 CC 15, this is Houston. 

03 07 UQ 32 LMP Roger. Houston, 15; go. 

03 07 U8 35 CC Jim, the people down here would appreciate It if 

you could give them something of a description of 
the operation of the PU VALVE during the LOT burn. 



03 07 1+8 51 LMP Roger, Karl. There was no operation of the - the 

PU VALVE at all until crossover. And then at 
crossover, it required a - a DECREASE, and then 
at about - about 5 minutes and a half into the 
burn, it started to increase, and I went to the - 
the INCREASE position at that time. All the 
operation of the PUGS manual operation occurred 
after crossover. 



03 07 kg 26 CC Okay; we copy. 

03 07 h9 ho LMP And, as I mentioned, about 5 and a half, I went 

to - 5 and a half minutes, I went - went to neutral 
and then the - it looked like the UNBALANCE was 
going to go - it was rapidly departing the zero 
region, and that was about the time we went 
through 6 minutes, and I put it into minimum at 
that time - into the DECREASE position. 

03 07 50 19 CC Okay, Jim. That answered our next question. 

03 07 50 58 CC And, 15, the people down here were very much 

tiarned on by your description of the swirls on 
the floor of Crisium. We trust you got some good 
photography of that; and, if you didn't, they'd 
very much appreciate having some next time 
aroiind. 



Tape 52/10 
Page 228 



03 07 51 l6 IHP Okay, We were discussing our photography, and 

we're going to try and stay as close to the pre- 
planned photos as we can and not overextend our- 
selves into what's already planned for the 6 days. 
But we will use our spare - spare film JMiciously 
for the kind of things you hear us talk about that 
you'd like pictvires of. 

03 07 51 37 CC Sounds very good. 

03 08 01 32 CC 15, this is Houston. Joe just came up from below 

to tell us that Farouk and company are ecstatic 
about what you've told them so far and that all 
of the SIM bay experiments are looking to be in 
excellent shape. 

03 08 01 50 CDR Okay. Thank you, Karl. That's good news. 

03 08 Olt 05 CC 15. We have your torquing angles. 

03 08 OU 12 CDR Roger. Torqued on the minute. 

03 08 l6 07 CC 15, this is Houston. 

03 08 l6 13 CDR Houston, Apollo 15; go. 

03 08 l6 17 CC Jiist to firm up our interest in those swirls on 

the floor of Crisium, the words we'd like to send 
up is that it'd be nice to get a three-photo 
convergent stereo sequence on it, and if you'd 
like settings, we recommend - - 

03 08 l6 33 CDR Okay; three photo ... 

03 08 l6 38 CC Roger. And if you'd like settings, we recommend 

f/8 at l/250th with a 250-millimeter lens. 

03 08 17 00 CDR Okay, Houston; vinderstand. Swirls on Crisium, 

three-photo convergent stereo, f/8, l/250th, with 
a 250. 

03 08 17 09 CC Roger. And now, you wanted us to remind you about 

your helmet and gloves when you take shots of 
Ingenuity this time ajroimd. 

03 08 17 2h CDR Okay; we'll tell him. 



03 08 17 31 CC 



03 08 17 h2 CDR 



And, otherwise, we have 
Everything's looking in 
fun on the back side. 

Okay. Thank you, Karl.

nothing more down here, 
great shape , and have

APOLLO 15 AIR-TO-GROUND VOICE TRAHSCRIPTION 

BEGIN LUNAR REV 2 
15, this is Houston. 

Roger, Houston. Looks like we're getting locked 
up now. 

Roger. That looks better now. 
Okay , Houston , 15 . 
Go ahead , 15 . 

Okay, Karl; while I got a minute here waiting on 
Crisium to show up, I'll give you a riondown on 
what we've done so far. 

Go ahead. 

Okay; we got the strips of photos of the Sea of 
Ingenuity - or Ingenii - and took a look at the 
light-colored swirls in the bottom of the mare. I 
coialdn't tell - No elevation associated with those 
light-colored swirls, and they're very distinct 
when you look at them at this angle. Also - looked 
at the - at the area Just adjacent to Ingenii; there 
is a very definite valley that cuts through the edge 
of the wall there , and with what looks like a rille 
in the bottom, what's been described as Vallis Alpha 
Reed [?] - I guess it is kind of -unique; it's the 
only one we've seen on the back side so far. We 
took some pictures of the rim deposits and then 
took a couple of shots going on out to Dumbbell. 
After that, we got set up for a Keyhole, took some 
convergent stereo on Keyhole , and got a couple of 
shots of The Bright One, along with some - some 
general- pictures to show the ejecta pattern, al- 
though I'm afraid that ejecta pattern on The Bright 
One is not going to show up too well. It's - it's 
very bright but it's - it's also such a large area 
that it's kind of indistinct as to definition. And 
then - took a couple of what I hope will be conver- 
gent stereos of the - of the rooster tail along by 
Saenger. And then got on to Ibn Yunus/Al-Biruni/ 
Goddard complex and took some convergent stereo of 



Tape 53/2 
Page 232 



the swirls to the - to the west of Ibn Yunus and 
to the north and west of Goddard. And now we're 
looking for the ones in Mare Crisium. 

03 09 17 32 CC Roger. Sounds like you did it up brown. 

03 09 1? 39 CDR Well, it does look - sometimes hrown, sometimes 

gray, Karl. But we'll see when we get back. 

03 09 IT ^7 CC Hey, let's keep those colors straight, fellows. 

03 09 19 18 CC 15, we can take HIGH GAIN to AUTO now. 

03 09 21 17 CC 15, we need to go back to REACQ - on the HIGH GAIN. 

03 09 21 28 CDR Roger. REACQ. 

03 09 22 1+6 CDR Houston, 15. 

03 09 22 kg CC 15, go ahead. 

03 09 22 5^ CDR Okay, Karl. Just a couple of general observations 

on Crisium while we're coming up on it. Proclus 
coming up from the east is really spectacular, you 
can very distinctly see the - the difference in 
the - in the color of the albedo in the excluded 
zone of Proclus, and as you're coming up across 
Crisium with Proclus aiiead, you can see the ray 
pattern very distinct - extending out across 
Crisium - and follow the ray patterns almost as 
far as you like. And the excluded zone in the - 
in the ray pattern is just very distinct at this 
point . 

03 09 23 31+ CC Excellent. 

03 09 2h 03 CDR And, Houston, from this angle looking at Proclus, 

about a crater diameter out to maybe a diameter 
and a half or so, you can see many small bright 
fresh craters, which appear to be in the general 
direction of a ray, like part of the ejecta blanket, 

03 09 2k 25 CC Roger. Dave, you mean to say that these small 

bright craters seem to be clearly related to the 
ejecta blanket. Is that correct? 



Tape 53/3 
Page 233 



03 09 2h 36 CDR That's the impression I get. They occur within a 

diameter to a diameter and a half of Proclus , and - 
they're about the same brightness as the inner walls 
of Proclus and they're small - Just small craters. 
I don't see any - Yes, I do see one which you might 
call a loop, which would suggest secondaries. They 
Just seem to lie in the general direction of the 
rays of the ejecta from Proclus. 

03 09 25 10 CC We copy. 

03 09 25 l6 LMP They're sort of localized to one area which is - 

probably - yes , on the - on the western side of 
Proclus, northwest side. 

03 09 25 32 CC We copy that. 

03 09 25 58 CC Do you - do these small, bright craters have more 

or less a unifonn size or do they come in varied 
sizes? 

03 09 26 10 LMP I'd say - Karl, this is Jim - I'd say they're 

various sizes. 

03 09 26 17 CC Okay. 

03 09 26 22 LMP It is - I - I guess it depends, Karl, on - what do 

you mean by sizes, there are various sizes within 
a certain sorting. They - they seem to be fairly 
well sorted within one range, but within that range, 
there is a distribution. And they're all much, 
much smaller than Proclus. 

03 09 26 kh CC Okay, we copy. 

03 09 28 03 CC 15, this is Houston. If you'll give us ACCEPT, 

we'll send up a - a state vector ajid a target load. 

03 09 28 15 CMP Roger. You have it. 

03 09 28 18 CC And, 15, we don't require a PIPA bias check at this 

time. And I have a terminator photo pad when you're 
ready to copy. 

03 09 28 29 CMP Okay, stand by 1. 

03 09 28 52 CMP And I'm ready for the terminator photo pad, Karl. 



Tape 53/1+ 
Page 231+ 

03 09 28 56 CC Roger. The T-start is 8l:UU:10, and there's a 

note here that the PCM cable may not reach to 
window 3. And if it doesn't, go ahead and run on 
the interva - intervalometer alone. And this per- 
tains to all future photography in window 3. 

03 09 29 21 CMP Roger. We understand. 

03 09 29 h3 CC 15, we'd like to go to AUTO again, and go directly 

from REACQ to AUTO without a pause. 

03 09 29 52 CDR You're in AUTO. 

03 09 30 07 CC The high gain looks good this time; thank you. 

03 09 30 13 CDR Roger. 

03 09 30 h6 CC 15, Houston. When you can copy, I have both a 

DOl pad and a TEI-5. 

03 09 30 59 CDR Stand by 1, Karl. 

03 09 31 08 CDR Okay, I'm ready to copy the pads.

03 09 37 23 CC 15, go ahead. 

03 09 37 29 CDR Okay, as a quick review here, DOI is a single-bank 

burn on B , with nominal procedures , with the excep- 
tion of having the A PILOT VALVE open. 

03 09 37 i+8 CC That's affirmative, and if we have no ignition, 

we'll postpone the burn a rev. 

03 09 37 55 CDR Roger; understand. 

03 09 1+1 00 CC 15, this is Houston. We're showing a low voltage 

on the battery relay bus down here. We think it's 
just a matter of instrumentation, but there's a 
couple of procedures we'd like to run through here 
to check it out. 

03 09 hi 27 CDR Go ahead, Karl. 

03 09 hi 29 CC Okay; first of all, we'd like to read - have an 

onboard read-out of the battery relay bus voltage, 
which is B-5 on the test meter. 

03 09 hi h3 LMP Okay. That's 5-B. 

03 09 I4I i+7 CC Roger. 

03 09 i+1 50 LMP It's reading 2.U - No, I'm sorry, l.h - 1.5- 

03 09 h2 08 CC Roger that reading. 



Tape 53/6 
Pajy;c 236 

03 09 l42 09 LMP Okay; Dave moved the - Stand by. Dave wiggled the 

selector to the ri^t - That's on B and the position 
that backs the B position and now we're reading 3.5. 

03 09 h2 29 CC Roger. And we just recovered our read-out of - 

We got a good voltage reading down here now. 

03 09 h2 37 LMP Good. 

03 09 h2 55 CC Okay; thank you. We'll think on that for a while 

and everything looks - everything looks fairly 
normal. 

03 09 h3 Ok LMP Roger. 

03 09 hk 3k CC 15, we have only one more question on that problem. 

And can you tell us what position you were in be- 
fore you went to 5-B on the test meter? 

03 09 hk »+5 LMP B was selected, Karl, but Dave moved the selector 

out of - just barely out of B and back into the 
B position to obtain the higher reading. 

03 09 kk 55 CC Roger. And what about the nimerical side; was it 

in 5? 

03 09 k3 01 LMP Yes, it was. 

03 09 i+5 06 CC We copy. Thank you. 

03 09 k'J 39 CC 15, this is Houston. And I have a map update 

for REV 3. 

03 09 hi 59 CDR Stand by 1, Karl. 

03 09 k8 23 CDR Okay; go with the map update for REV 3. 

03 09 k8 28 CC Roger. LOS: 82:28:16; l80 is 82:lt8:U2; AOS is 

83:ll^:5U. 

03 09 k8 56 CDR Okay, understand. LOS: 82:28:16; l80 degrees, 

82:li8:l+2; AOS, 83:lU:5l+. 

03 09 1+9 07 CC Roger. And while you're on that page, I have 

information for the landmark J-1 observation. 

03 09 k9 16 CDR Okay; go ahead.

03 09 kg k9 CC That's correct. 

03 09 55 20 CC 15, this is Houston. 

03 09 55 26 CMP Houston, 15- Go ahead. 

03 09 55 29 CC It's our understanding that we'd agreed that you'd 

send down magazine niombers and final frame numbers 
on each path on this photography, and if you're 
in agreement with that, we'd like to have the mag- 
azine and frame number on the orbiteil photography 
and also on the terminator photography. 

03 09 55 55 CMP That - that's all in an agreement that I've got 

with Spencer, Karl. I think right now, we're too 
busy to do that , and after we get the landing out 
of the way, we'll go back eind recap all the film 
and start from scratch. 

03 09 56 07 CC Very good.

03 10 07 53 CDR Houston, 15. 

03 10 07 55 CC One more comment on the hattery relay bus voltage. 

From all indications., it is indeed an instru- 
mentation problem, but we have one more question 
and that is to confirm that the MAIN A - MAIN 
BUS A and MAIN BUS B FUEL CELL talkbacks are normal 
and - and have been normal during this period. 

03 10 08 22 CDR Yes, that's affirmative, Karl. They have been 

normal. 

03 10 08 27 CC Thank you. And, at the present time, all the 

systems, otherwise, are looking fine, and you're 
GO for DOI. 

03 10 08 37 CDR Okay; understand. GO for DOI. 

03 10 l6 31 CC 15, this is Houston. We'd like to verify, over on

breakers, 1 MAIN B and 2 MAIN A are open. And, if 
they're not open, let's open them. 

03 10 l6 50 LMP Stand by. 

03 10 17 03 LMP Okay. The two circuit breakers that are open are 

0^ TANK HEATERS, 50 WATTS, 1 MAIN B, and 2 MAIN A. 

03 10 17 12 CC Roger. I understand they have been open. Is that 

correct? 

03 10 17 19 LMP That's correct. 

03 10 17 22 CC Okay. The reason we ask is that the temperatures 

weren't quite as we expected. Thank you.

perch. 

03 11 15 h6 CC Gtood to hear you coming around that corner. How 

do things look? 

03 11 15 53 CDR Okay. Burn status report. Burn was on time. Burn 

time was about 2h.O - about half a second shorter 
than predicted; there was no trim; residuals were 
plus .6, plus .0, minus .1; DELTA- V^, minus k.k; 

fuel 29 - 29.25; and the oxidizer was 29.55; 
Unbalance, 100 increase. 

03 11 16 3^ CC Thank you, Dave. We copy all that. 

03 11 16 hi CDR And I'll tell you, it's really spectacular, when 

you can see the central peak of Tsiolkovsl^ coming 
up over the horizon before you see the rim. 

03 11 16 51 CC Hey, that's an interesting astrophysical 

observation. 

03 11 17 59 CDR And, Houston, I5. The G&N had us in a 58. U by 10.0. 

03 11 18 08 CC We copy, I5. 

03 11 21 lU CDR Houston. 15. We're in an attitude now in which 

we cannot see the surface. But our initial 
impressions after the burn, when we could see the 
surface, is that we were rolling in on a high-

same as the mapping cameras times, and we wotild 
like to change a shutter speed at Bk:2k^ Instead 
of 125th, we want l/250th at 8k :2k. 

03 11 U8 LMP Okay. Understand 8U:2lt. We'll change it to f 250 

[sic] rather thsm 125; and on the map pad, it's 
81+: 1*2: 23 and &k:3k:lkf and the pan camera pad's 
the same. 

03 11 1+9 00 CC That's all correct.

03 12 15 32 LMP Houston, 15. 

03 12 15 35 CC Go ahead, 15. 

03 12 15 38 CMP Okay, Karl. Got a few numbers for you on the ex- 

tension times . We started the whole thing off 
at 8U:06:30. And got the covers open, the MAPPING 
CAMERA EXTENDED, and the extension was ahout 3 min- 
utes instead of 1+. Then we DEPLOYED the GAMMA RAY 
and the MASS SPEC BOONE for harber pole plus 2 sec- 
onds. The GAMMA RAY turned barber pole after 
6 seconds, and the MASS SPEC turned barber pole 
immediately. And I was svispicious of the MASS 
SPEC, so we tried them again and got the same 
results. Turned the X-RAY, ON at 8U:15:10 and 
LASER ALTIMETER, ON at 8U:15:30. 

03 12 16 25 CC Roger, Al. We copy. 

03 12 18 25 CC 15, this is Houston. Would you verify that the

need a DOI trim. I've got a couple of trajectory

03 13 ih 50 CDR Yes, it'd be interesting. Go ahead. 

03 13 lU 5^ CC Our tracking data tells us that your current orbit

out-of-plane of the cross track? 

03 13 15 21 CC Stand by. 

03 13 16 03 CC Dave, your out-of-plane data looks like about

noted the out-of-plane part of the DDI. They're 
telling me here that you burned, a perfect LOT, but 
the state vector they gave you was slightly in 
error. So they got rid of - they - they 
made corrections for that during DOI , so that we're 
standing pretty close to perfect now. 

03 13 18 13 CDR Okay. I got to admit we did have scane question 

about that but figured you all had it in hand, 
as you usually do.

03 13 20 kk CMP Okay, Karl. Guess I should bring you up to date 

on a couple of things here- Everything went as 
planned on the - on the terminator photos. The 
pan camera and the mapping camera pass started 
on time and stopped on time. Turn - Got the 
mass spec boom deployed and gamma ray boom 
deployed; the mass spec deployed in 2 minutes 
20 seconds , and the gamma ray deployed in 2 min-

the Tetons, or do they give you some other appear- 
ance? 

03 13 38 12 CDR No. As a matter of fact, frcaa this altitude, even 

though we're low, they appear to he smooth and 
rounded. There aren't any jagged peaks that we 
can see. And even though they're cratered and 
rough in texture on a small scale, they really 
don't look anything like the Alps or the San 
Juans or any of the other familiar ranges we know. 

03 13 38 38 CC Roger. Is there anything that looks like hare 

rock on them? 

03 13 38 hd CDR I think we can see seme boulders , but there are 

no apparent Jagged peaJts that we can tell or that 
we can see frcm this - this particular altitude 
yet, aJ.though some of the - the shadows look 
fairly sharp. 

03 13 39 02 CC Roger. 

03 13 39 05 CDR And, Karl, speaking of shadows, there seems to be 

enough light being reflected off the sides of the 
mountains around to supply some light dcwn on the 
landing site. And the rille is quite distinctive 
as we pass right over it. 

03 13 39 20 CC Beautiful. That must be an eerie sight in a half- 

light. 

03 13 39 27 IMP Well, it was, sort of.

03 13 hk 09 CC 15, this is Houston. How do you read? 

03 13 kk ih CMP Loud and clear, Houston. 

03 13 iC CC Roger. We've finished picking up data on the 

mass spectrometer. Leave the discriminator as It 
is, and we're ready to go to put the EXPERIMENT 
in STMDBY now. 

03 13 hk 38 CMP Understand; you're ready to put the MASS SPEC in 

STMDBY. 

03 13 hh hi CC Roger. And then you can start to put the blunt 

end forward, anytime you care to, 

03 13 hk kS CMP Roger; we're maneuvering now. 

03 13 k6 k2 CC 15, this is Houston. Dave, the Surgeon would like 

to have a special reading of the PDR from you 
tonight. Your reading last night was not in 
agreement with the other two crewmembers , and 
they'd like to get another data point on you. 

03 13 kj 05 CDR Okay. We copy, Karl. We'll give you all three 

readings . 

03 13 kf 09 CC Roger. They'll accept them gladly. 

03 13 ^8 28 CC 15, this is Houston. Whenever you can copy, I have 

the TEI-12 pad. 

03 13 k8 37 CMP Stand by, Karl. 

03 13 k9 Ok CMP Okay, Karl. I'm ready to copy TEI-12. 

03 13 kg 09 CC Roger. TEI-12, SPS/G&W; 38IIO; plus 0,58, plus 

1,00; 101:36:08.38; plus 28U5.0, minus 0380.2, 
minus OO63.8; 180 , 107, 35*+; the rest is NA; 
U-jet ullage for 12 seconds. And this assumes 
the burn undocked and no circular burn, and the 
GET of landing is 196 hours at MPL. 



Tape 56/6

03 13 50 22 CMP Okay. TEI-12 readback: SPS/G&N; 38IIO; plus O.58, 

plus 1.00; 101:36:08.38; plus 28U5.0, minus 0380.2,

Undocked, no circular burn. Assiames landing at 
196 GET at the MPL. 

03 13 50 58 CC That's all correct. 

03 13 51 31 CC 15, we need the mode switch in AUTO, please. 

03 13 51 ^8 CMP Houston, 15. What mode switch you talking about, 

Karl? 

03 13 51 57 CC That's the CMC MODE switch. I guess we need to get 

into AUTO before we can execute this maneuver. 

03 13 52 05 CDR That's affirmative. And I'll go into AUTO as soon 

as I coniplete the Uo degrees of roll. 

03 13 52 10 CC Roger. 

03 13 55 07 CC 15, Houston. On the MASS SPECTROMETER operations 

down there at 59 minutes, we'd like to have you 
keep the DISCRIMINATOR, LOW, as it is now. And, 
as the ION SOURCE goes ON , we would like to have 
you pause in the OFF position until you get our 
cue . 

03 13 55 30 CMP Roger; imderstand. You wanted the DISCRIMINATOR 

left in LOW, and you WEoated us to pause in the OFF 
on the ION SOURCE on your cue. 

03 13 55 37 CC Roger. And I - I - think you know that we'd 

probably - that we - we don't want to go into those 
operations until we have got into the correct 
attitude. 

03 13 58 09 CC 15, this is Houston. 

03 13 58 Ik CDR Houston, 15; go ahead. 

03 13 58 17 CC A couple of special notes on the hardware. First 

of all, on - on the SYSTEMS TEST meter - we don't 
fully understand why that switch did funny things 
for los, and we have some back in - the fairly ex- 
tensive tests going on down here still trying to 
understand it. And we suggest that you leave the 
meter in the 5-B position until we do get some 
handle on what happened there. 



Tape 56/7

03 13 58 1*6 C^4P Okay, Karl. We copy that. 



03 13 58 HQ CC Okay. And I Just heard the word that, if you 

really need it, go ahead and use it, but if don't 
have a strong reason for moving it, leave it as it 
is. And on - We - we're observing the radiator 
temperature - occasionally cycling above 80 degrees 
This is out of limits, and we don't really have a 
good solution for this at the present time. We 
could think about turning on the evaporator, but 
that would foul up the mass spectrometer, and we'd 
rather not do that. The only things that it's - 
that the high temperature would be bothering are 
the IMU PIPAs , and we have - we - Since the 
temperature is cycling up and down, cools off on 
the back side of the Moon, we - on the dark side 
of the Moon , we - we think there ' s no - no imminent 
danger to that system. So, our feeling on that is 
to leave the system as it is. 

03 13 58 52 CDR Okay. We understand. 

03 1^* 00 58 CMP Houston, this is 15 with some onboard read-outs 

for you and PRDs. 

03 Ih 01 Ok CC Go ahead, 15.

03 21 31 32 CC Apollo 15, Houston. 

03 21 32 06 LMP Houston, 15. 

03 21 32 07 CC Good morning, Jim. We're waJcing up you [sic] a 

little early to tell you a few things before you 
go aroomd the corner because you only have k min- 
utes in the old Flight Plan. So, if you guys are 
awaJce and ready to listen, I'll give you a few 
words . 

03 21 32 23 LMP Okay, Bob. Go ahead. 

03 21 32 25 CC Okay. At the moment - Okay, one short one. We'd 

like you to go HIGH GAIN antenna to AUTO so we 
don't lose you just before you go around the corner 
there. Okay - - 

03 21 32 kg LMP We're in AUTO. 

03 21 32 50 CC And at the moment, 15, you're sitting in a 

58.8 by 7.6 orbit; and, at PDI , we're extra- 
polating you to approximately 33,000 feet. This 
is with a plus or minus 9OOO feet on top of it , 
due primarily to the uncertainty of the RLS. 
Because of this, we're pretty well decided we're 
going to do DOI trim, but we're holding a decision 
on that until after we get the data for this pass , 
which we'll process, of course, while you're be- 
hind the Moon. We're talking about something like 
a 6-foot-per-second burn and probably targeting 
for 50,000 feet at PDI. As far as the rest of the 
spacecraft, all your systems look good. No prob- 
lems at all during the night. We do have a pan 
camera problem, which may or may not be serious. 
We're going to look at it later on today after 
CIRC, and we'll be coming up with a procedure for 
Al for that later on in the day, A short item. 
We'd like a - during your eat periods if you have 
the time, also would like you to give us a gain 
step — on the gamma ray — up to 1. And we'd 
like to get a medication report, too, this morning. 
We apparently missed that last night. Over. 



03 21 3h 28 LMP 



Okay. Copied all that. And no medication.

03 21 hh kl CC And, Apollo 15; Houston. You're looking good 

going around the horn. Systems all look good. 
At your convenience, while you're down the SIM

03 22 38 19 CC Apollo 15, Houston. Over. 

03 22 38 U8 CDR Houston, Apollo 15- You're 5 l^y. 

03 22 38 50 CC Roger. You're 5 "by also. And we got three more 

Plight Plan updates due you, if you're ready. 

03 22 39 ok CDR Okay. Go ahead. 

03 22 39 05 CC Okay. First one I'd like to mention is 95:02 - 

95:02. And it reads, in addition to those two lines 
on the Og HEATERS at the top of the page, we want 

to add a third line that fyJSI "CB 0^ TANK 100-WATT 

HEATERS, 3 MAIN B, open. Panel 226." Over. 

03 22 39 1+8 CDR Okay; understand. "CB 0^ TANK 100-WATT HEATERS, 

3 MAIN B, open." 

03 22 39 53 CC Roger. And after you guys give us the PRD read- 

outs, we'd like to exchange the CMP and CDR PRDs 
because, Dave, yours appears to be malfunctioning, 
and they ' d like to have two working ones on the 
surface. Do you copy? 

03 22 kO 16 CDR Okay; imderstand. Exchange CMP and CDR PRDs. 

03 22 1*0 21 CC Okay. And the next update 's for the IM Activation 

Checklist. And while you're going - getting that, 
I'll give you a little update on our expectations 
for the DOI burn. 

03 22 kO 38 CDR Okay. Stand by. 

03 22 Ul Oh CDR Okay. Go ahead. Bob. 

03 22 Ul 05 CC Okay. The update to the Activation Checklist is 

on page 2-6. 



Tape 62/2 
Page 260 

03 22 1+1 26 CDR Okay; 2-6. Go. 

03 22 hi 28 CC Okay. We'll delete the third line of step 2. And 

we'll add a step 5, which reads "(l) LMP's SUIT 
ISQL valve to SUIT FLOW; Commander's SUIT ISOL valve 
to SUIT FLOW, for 15 seconds. And then SUIT 
DISCONNECT, for both." And then (2) is "SUIT GAS 
DIVERTER, PUSH-CABIN." What we're doing here, Dave, 
is basically making sure that we're blowing any 
glass particles that might have settled in through 
the little holes into the inlet hoses . Going to 
blow those out. Over. 

03 22 k2 26 CDR Okay; understand. Step 2, scratch the third line. 

Step 5, "IMP and CDR SUIT ISOLATIOW to SUIT FLOW 
for 15 seconds. And then SUIT DISCONNECT, for 
both." And then "SUIT GAS DIVERTER, PUSH-CABIN." 
And that sotinds like a pretty good idea. 

03 22 1+2 1+1 CC Okay. And, I'll give you a few clues as to what's 

liable to be coming up for the DOI trim burn. Cur- 
rently, we're showing a 5.8T perilune on REV 1I+, 
which is 35,000 feet plus or minus 9000 with that 
RLS uncertainty. And, what's being proposed now 
is not an SPS b-urn, because it will be very short, 
but an RCS burn of 20 seconds which is 3.2 foot per 
second, which would raise us to 50,000 feet. Will 
cost us about 27 pounds of gas, and we're looking 
at a T. time of 95:56, which you will note is 

20 minutes early - earlier than in the Flight Plan, 
which means we're going to have to compress some 
of that stuff together. Over. 

03 22 1+3 35 CDR Okay. Understand 95:^6. And looking over the 

Flight Plan, it looks like, had we gone on the 
original DOI trim, we had about 1+0 minutes of SIM 
data there. Maybe we can just scratch that. 

03 22 1+1+ 06 CC Roger, Dave. We're Just going to have to trim that 

SIM stuff off a little bit early, because we don't 
have the time right here. 

03 22 1+1+ 15 CDR Okay. I guess what I'm thinking is, it takes us a 

lot of time to go through that. Turn it on and turn 
it off. And, of course, we could always use time, 
but we'll get it.

Dave, we don't show you turned anything on this 
morning; it's Just a long protracted business of 
turning it off. And I guess, that was - used 
to be starting after the TV pass. And I guess that- 
what we're saying right now is it looks like we're 
going to start turning that off during or before 
the TV pass. 

Okay. You're right. Bob. We'll do that; that 
looks good. 

Okay, and we'll be getting you a real pad coming 
up some time soon. 

Okay; we'll be standing by. 

And, Dave, If practicable, we'd prefer to have it 
turned off before or after the TV, because then we 
can watch it being turned off. Otherwise, we can't 
see it during the TV. But you can certainly turn 
part of it off before and part after. 

Okay; understand. We - we'll do it some time other 
than the during the TV. 

Correct. 

Okay, Dave. And we got a few updates here for the 
time after the TV pass, if you're ready to copy. 
Some other stuff that we are moving up because of 
this . 

Okay; ready to copy. Go ahead. 

Okay. At 95:28, we will schedule a "P52 option 3."

03 22 56 31 CMP Okay; Houston, 15 . If you want to orient yourself 

on the TV there. Bob, we just came over Macrobius-A, 
and the small crater that you just saw - we just 
went by, is Roraer-J. We're coming up on - on 
Romer-K here in a moment, which means that very 
shortly, we'll be coming up over the Littrow Rille 
- Rima Littrow. 

03 22 56 5T CC Roger. We've got our little charts out here. 

03 22 57 0^ CMP Okay. 

03 22 57 21 CMP Yes. It looks like Romer-J we're just coming up 

on now. In fact, we'll pan down into it, 

03 22 57 31 CC Beautiful shot. 

03 22 58 55 CMP Okay, Bob. You can see we're up over one of the 

Littrow rilles now. You can see the rille cutting 
diagonally there from about - 6 o'clock to 2 o'clock 
across the picture, and you can see seme of the 
wrinkled ridges. In fact, there's a beautiful 
wrinkled ridge right below us right now. 

03 22 59 12 CC Roger. I believe you. I see it. 

03 22 59 1^ CMP I'll pan up along the wrinkled ridges so you can 

see. And they're a very, very distinctive thing. 
Now we're out over Mare Serenitatis. You can see 
some of the Littrow rilles in the background there, 
some of the graben-type rilles, and some of the 
wrinkled ridges down on the - on the far - or on 
the - on the close corner here. 



03 22 59 50 CMP 



Yes , we should be ccming up on the inner ridge 
system here in a moment, and we - we'll try and pan 
down along the - the inner ridge. 



Tape 62/6 
Page 26h 

03 23 00 12 CMP Yes. That looks like the inner ridge system there, 

and if your picture's like mine, you should be 
picking it up pretty well. 

03 23 00 35 CMP Those ridges in places look like they could be 

nothing more than a - than a - than a flow that 
stopped there - flow front. In other places, they 
look like - like a - like it's buckled material 
underneath, folded to - to give it some elevation. 

03 23 00 51 CC Roger. 

03 23 01 23 CC And that was a good one, Al. And if someone who's 

not just looking out the window^ will give us POO 
and ACCEPT, we'll send you up a - not POO, just 
ACCEPT. Pardon me. We'll give you state vectors 
and a target, while we're taking a view. 

03 23 02 08 CMP Bob, I'm going to pan forward a little bit, and 

you can see the beginnings of the Apennlne Front 
showing up on the far side of Serenitatis. 

03 23 02 15 CC Roger. We see that. 

03 23 02 2h CMP And off on the left there, that's the - the Haemus 

Mountains aroiind south of the Apennines. 

03 23 02 hi CMP See how - when you're coming up at low altitude on 

these mountains , how - how striking they are in the 
distance? It's really hard to miss any from such 
a long ways away, 

03 23 02 52 CC I hope you can miss them. 

03 23 03 02 CMP I guess that's up to you guys. 

03 23 03 OU CC Roger. Speaking of that, the bum attitude's going 

to be lOk degrees, so you might keep that in mind 
when you get down here. You're getting kind of 
close to it now, or - beginning to get close to it. 

03 23 03 18 CMP Okay. 

03 23 03 51 CMP There's a very interesting little fissure just 

below us here. Bob. It looks like there might be 
a little flow coming out of it, but it's - it's 
almost an arrowhead- shaped affair. And, it cer- 
tednly doesn't have any features like any - any

impact. It's very sharp and distinct and makes 
a very distinct arrowhead. And here we come up 
on the ridges on the west side of Serenitatis, 
Just at the foothills of the Hadley Apennines. 
And you can see, there is - there is some relief 
as we look hack to the south there , there is some 
very distinct relief in - in - in the shore of 
Serenitatis, with some wrinkle ridges that follow 
the contour. And some - what look like fairly 
distinct arcuate rilles that also follow the con- 
tour. I think that when we get up very close here, 
you can see - In - in the field of view there right 
now, is a lineament that looks like it might be 
some sort of a collapsed lava tube , and you can 
also see down in here the - the mare material looks 
like it's pooling in the - in the foothills of the 
mountains; and in some places, you can even see 
what appears to be a frozen shoreline, so to speak. 

03 23 05 07 CC Beautiful, beautiful. 

03 23 05 2k CC Roger. We can take black now, too. 

03 23 05 27 CMP Okay. Okay, Bob. I'm going to take the TV out 

of this window and get It located in window 3, 
so we can all have a good look at the landing site, 

03 23 05 ho CC Okay. 

03 23 06 01 CMP Sorry about that; we're Just a little bit late, 

but you can see the edge of the rille there as 
we go beyond it . And you C6Ui see the blocky 
features inside the rille. And now we're out 
across the plain on the other side. That was 
very fast . 

03 23 06 16 CC That was a q.uickie. 

03 23 06 kk CMP Okay. In the field of view right now, Bob, is 

beginnings of Bradley Rille , and you can see it 
cutting back off to the southwest there. 

03 23 06 53 CC Roger. Looks kind of like our rille. 

03 23 06 58 CMP Yes. It does, doesn't it? 

03 23 09 22 CMP Okay, Bob. I guess that about does it. We're at 

the terminator, and we'll pick up the attitude now.

have a burn report for you. 

Roger. Ready to copy. 

Okay; on time - burn time was about I8 or 19 
seconds. The residuals were minus .1, plus .2, 
plus .2, DELTA-V was plus .8, and the G&N has a 
59.it by 10.3. 

And copy, Dave. 

And, 15, I have a landing site observation pad for 
you when ready. 

Roger. Go ahead. 

T-horizon: 96:57:10. Stand by. 

Hey, 15, you still with us? 

Roger. We're there, and T-horizon: 96:57:10. 
Standing by for TCA minus 20.

OI+ 01 01 hQ CC Go ahead, 15 . 

oh 01 01 53 CDR Okay; looks like FAG owes us one, I had no trouble 

picking up Index Crater at all. The surface looks 
generally smooth. I saw no big boulders. I saw 
more craters than we're normally used to seeing, 
but I think that's because of the resolution of 
the photography. I can see a - a fair amount of 
boulders in the bottom of the rille. Most of the 
surface seems to be pretty subdued and rounded. 
I did see some debris around some of the fresher 
craters. And, of course, I don't know exactly 
what size, but if we're looking at 3-feet reso- 
lution on this, I'd - I'd say I didn't see any- 
thing larger than - I guess, at the most, maybe 
15 feet or so, but that's - that was a unique 
rock. The - the area, in general, looks pretty 
good. I don't think we'll have any problem pick- 
ing it up, and I don't think Al will have any 
problem at all identifying Index Crater.

Houston, Falcon. While that's running through there, 
we're going back through our notes, checking over 
the activation. And one thing we missed there was, 
just before mdocking, we ran the suit pressure in- 
tegrity check, and the first time aroiand, we got a 
greater than 3/lOths decrease in 1 minute. So we 
cycled through both regulators, did that test, and 
came back and ran the suit integrity check again, 
and it was Just fine. It was about 1/lOth in a 
minute . 

Okay, Falcon. We copy that. Thank you. 
Okay. 

Falcon, Houston. 
Houston, Falcon. Go. 

Roger, Dave. Talk about reviewing notes, we did 
so, also, and we found one we'd like to pass to you 
before LOS. 

Okay. 

Dave, we - we're working out a procedure down here 
that we SIMed, and it's in the event of a low 
thrusting DPS during PDI. We're prepared to call 
to you - an RCS thrust augmentation for 1 minute, 
at about 1 minute or a minute and a half into the 
burn. And recommending doing it on the LMPs TTCA, 
if we have to do it at all. What do you think? 

That's fine. We'll try that if we need it. 

Okay. The procedures are very simple. We'll call 
it to you as we've measured your thrust. 

Okay. And I guess you'll call "on" and call "off" 
with the TTCA, is that correct?

quick summary here before ve get on with it. The 
general terrain looks exactly like what you had 
on 11+ . And many of the craters that we use for ID 
were completely washed out with no shadows , and I - 
that's probably because the topo data - data just 
wasn't that good. And 1 think we're setting a 
little off in attitude, but we're in fairly good 
shape. And, when we get around to the SEVA, we'll 
try and pin down the location exactly. I had a 
little bit of dust at 150 and completely obscured 
at 50 feet. It was IFR from then on down. And 
the rest of it, you can probably see it as well as 
we could.

Ok 08 59 59 CDR-LM I think - as best I could find, I think we're 

fairly close to Salyut. But I guess the best thing 
to do is to press on and get to - the SEVA where we 
can take a look around. It's very hummocky, and, 
as you know, in this kind of terrain, you can hardly 
see over your eyebrows. There's very little to tell 
us exactly where we are in our local position.

Oh 11 00 03 CDR-SEVA Okay, Joe. We've got all the photos. Here you 

go, Jim. 

Oh 11 00 07 IMP-LM Okay. I got it. 

Olt 11 00 09 CDR-SEVA Okay. And let me start - "by 12:00 o'clock, 

Joe, and I'll go around real quick on the far 
distant horizon. Apparently, across the 
rille, I can see - just ahout our 1 o'clock, 
now - a very large mountain, which I'd have to 
call Hill 305. 

Oi+ 11 00 31 CO Roger. 

Oh 11 00 32 CDR-SEVA And - all of the - all of the features around here 

are very smooth. The tops of the mountains are 
rounded off. There are no sharp jagged peaks or no 
large boulders apparent anywhere. The whole 
surface of - the area appears to be smooth, with 
the largest fragments I can see are in the walls 
of Pluton. There are no boulders at all on St. 
George, Hill 305, Bennett, or, as far as I can tell, 
looking back up at Hadley. Hadley's sort of in 
the shadow. It's a gently rolling terrain 
completely around — 36C degrees — hunmocky, much 
like you saw on lit. The pitch line ac - across 
the rille, from Hill 305 around to 1 o'clock, 
seems to be - slightly lighter in albedo, with some 
white marks from craters, recent craters, apparently. 
Bennett Hill also has - a lighter-colored albedo. 
One face of it, that facing the Sun, now is almost 
completely white. As I come around to my 2 o'clock, 
the horizon is really the Northern Complex. I 
can see, as I mentioned before. Chain, Icarus, and 
Pluton are very roiinded, subdued craters. It looks 
like the southern rim of Pluton is on the same 
level as our location here. The northern rim is 



Tape 70/3 
Page 3h9 



somewhat higher. I'd say — dist - distances are 
difficult — but maybe 50 meters higher. I can 
see the scarp on the other side of the north 
rim of Pluton. All of It very flat, smooth, 
and gently rolling. Inside walls of Pluton 
are - fairly well covered with debris, fragments 
up to, I'd estimate, maybe, oh, 2 to 3 meters, 
irregular, no layering. Just sort of scattered 
around, and maybe the walls have 5 percent 
fragments . As I look on around - to the north , 
Moimt Hadley itself is in the shadow, although 
I can see that the ridge line on the top of Mount 
Hadley - it too is smooth. I see no Jagged peaks 
of any sort. The hill I would call number 22 on 
your map - far distance - also looks smooth and 
roxmded; no prominent features. I'll skip the 
distant field around to my 6 o'clock, because it's 
all in the shadow. And looking into the Sun, of 
course, obliterates almost everything. As I look 
on down to my - 7 o' clock > I guess I see Index 
Crater here, the near field. But, back up on 
Hadley to the east of Hadley Delta, why, again I 
can see a smooth siirface. However, I can see 
lineaments. I'll take a pictiore for you. There's 
some very interesting - take - Silver Pass [sic] and 
look at 13 on your map. I can't tell whether it's 
13 or l6, right now, because of the Sun. But 
there appear to be lineaments or lineations running 
dipping through the northeast, parallel. And they 
appear to be, maybe, 3 percent to h percent of 
the total elevation of the mountain, almost 
uniform. I can't tell whether it's structure or 
internal stratigraphy or what. But there are 
definite linear feattires there, dipping to 
the - to the northeast, at about - oh, I'd say 
30 degrees. And, as I look up to Hadley Delta 
itself, I can see what appears to be a sweep of 
linear features that curve around from the western 
side of Hadley Delta on down to the Spur down 
there. And they seem to be dipping to the - to 
the east at about 20 degrees. These are much 
thinner - lineations on the mountain than I 
saw before. These probably are less than 1 percent 
of the total elevation of the mountain. The craters 
on the side of Hadley Delta are rather few. Around 
Window and Spur, those that you see on your maps 
are the only ones I can see, and there appear 



Tape TO/U 
Page 350 



to be, oh, about a dozen of them in that particular 
area. I might associate those with a secondary 
cluster, if I took a guess at it. I see nothing 
that indicates any flow down - or a lajidslide 
down Hadley Delta, only some subtle changes in 
topography. There's one bright fresh crater 
right next to St. George on the eastern side with 
almost white albedo, and it's got an ejecta blanket 
about a crater diameter away. How are you copying 
so far? 

Oh 11 05 5I+ CC Superb description, Dave. Got every single word. 

Beautiful. And we'll ask you to hustle on aro\md 
and give us something on the near field, plus 
a comment on ALSEP deplojrment possibilities . 
Superb communication, though. Beautiful. 

oh 11 06 11 CDR-SEVA Okay. Coming on around to St. George, it again is 

a very subtle old crater, but in this case, I can 
see some lineaments running - dipping to the west 
at about 20 degrees, parallel to the rim of the 
crater. These two are very small, less than a 
percent, and continuous ... *** parallel. The 
rim of the crater is very subdued and smooth. 
Coming around - I'll Just take a q^uick look at 
the near field for you here. It's about generally 
the same. The crater density is, I'd say, quite 
higher - somewhat higher than I expected. Sizes 
are mostly less than about 15 meters. The only 
large crater that I see is what I believe to be 
Index back here, about the 8 o'clock, and it 
has a very subtle rim, almost no shadow in the 
bottom of it. I think that's one of the things 
that was deceiving on the descent. There are 
very few deep dark craters in the area. The 
distribution of fragments appears to be less than 
***2 percent. On the surface, they vary from 
a *** centimeter in size up to, maybe, 3 or H 
inches. Most of them appear to be angular. I 
see some white ones. I can give you some more 
of that out of the - out of the window. 
Traff icability looks pretty good. It's humraocky; 
I think we'll have to keep track of our position, 
but I think we can manipulate the Rover fairly 
well in a straight line. And I - I can see the 
base of the front. As near as I can tell - as 
a matter- of fact, I think I see where the front 



Tape TO/ 5 
Page 351 



runs into the level ground, where we get that 
5-degree inflection. I see no boulders over there 
whatsoever. Looks like we'll be able to get around 
pretty good. 

oh 11 08 00 CC Roger, Dave. We copy. 

OU 11 08 05 CDR-SEVA And as far as ALSEP deployment (laughing), 

unfortunately, looking straight ahead in zero 
phase - it's blocked out somewhat, but if there's 
continuity of the surface that I see in our general 
position, I don't think we'll have any trouble 
taking the ALSEP out 300 or so and placing it. 
I just noticed a couple of items on the far side 
of the rille on the - on the flat horizon . . . west 
there. Looks like a couple of very large boulders 
on the horizon; just unique, two of them. They're 
quite bright and - and quite sharp. I cannot see 
Hadley Sea at all, as we thought we might be able 
to. Bennett peak is about all I can see in 
inspection of Head Valley. 

ok 11 08 51 CC Roger, Dave. Is that down towards Head Valley? 

oh 11 08 53 CDR-SEVA Traf f icability up - right. Down - yes, that's 

correct. And the traf f icability up to the Northern 
Complex looks the same. I see no large boulders. 
The slopes go up maybe 5 *** 10 degrees at the most. 
And beyond that, all the terrain looks pretty - pretty 
smooth. I can see some young, fresh craters in 
our vicinity, which are sort of interesting in 
that there's some very small debris - in the 
crater itself and on the rim, and it's somewhat 
lighter gray than the general surface, the debris 
being on the order of, oh, centimeters or so, 
but quite young and fresh. And I see a - at 8 or 
9 - or 3 o'clock, a very deep crater, old crater, 
smooth. But I can't even see the bottom, and it 
can't be more than, oh, 60, TO meters away. 
I think that ' s one of them 1 was avoiding on the 
way in. That very mel - well may be November. 

Oh 11 10 05 CC Roger, Dave. And how far away do you think that 

might be. It sounds very exciting. 

0l+ 11 10 15 CDR-SEVA Joe, distances are very deceiving. I'd guess maybe 

60, TO meters. There's another somewhat deeper 



Tape 70/6 
Page 352 



one just to the north of that. It - it looks 
to me, and Jim has the same impression looking 
out the window, that we're much closer to Pluton 
and - and St. George, and all that stuff, than 
we expected to he. 

Roger, Dave. We think it just may look closer 
to you. Sounds like we're in tusiness, old 
friend. 

Yes, it - it just looks closer, I'm sure, hut 
we are indeed in business. And I think, once 
we get through here and I hop back down, why, 
we can talk over more of what I've been seeing up 
there . 

Roger, Dave.. You're coming up on 30 minutes into 
this SEVA, and we don't have any more questions. 
You've answered everyone beautifully. Outstanding. 

0I4 11 11 17 CDR-SEVA Okay, Joe. I'll take another quick look around. 

See if anything - looks unique. There's Just 
so much out there, I could talk to you for hours. 
Do you have any specific questions before we 
clo - call it quits? 

Oh 11 11 3li CC Dave, we're - we're hoping you will be talking to 

us for hours about it. We don't have any specific 
questions right now. We'll think about it and 
talk to you again, once you button up. Maybe one 
last look for an ALSEP deployment position. And 
we've copied that you've gotten both sets of 
pictures for us. 

Ok 11 11 55 CDR-SEVA That's correct, Joe. I - I limited myself somewhat 

on the - the 500s, becaiise I think we'll get a chance 
to take a lot more of those. But I did get the pans 
for you. 

Roger, Dave, We're quite - -

of - of the South secondary Cluster? 

Oh 11 12 32 CDR-SEVA There's a gentle rise, just to o\ir south and - I 

don't see anything that's really prominent, as 
far as elevation, I think the elevations on 
the - the models we've been working with were 
somewhat exaggerated, because I just don't see

Stand by, Dave. 

Okay. 

Hadley Base, Houston. 

Go ahead, Houston. Hadley here. 

Roger, troops. While you're getting squared 
away there, regarding your question, Dave, on 
the SEP 1 unit , we think that you had some residual 
condensation in your hoses. And when you stood up, 
it ran down into the separator and water-logged it, 
causing it to go off the line. It'll drain - be 
draining, and we think the next time we try it 
out, it'll be okay. Over. 

OU 11 22 51 CDR-m Okay. I understand. But, we haven't seen any 

water around lately, but there has been quite 
a bit of moisture on the windows . There was 
when we powered up; we had to bring the heaters 
on for a while to get the windows cleared. 

Roger, Dave. Understand. We think the water was 
condensed in the suit hoses. 

Okay. I understand. 

I think I know where we are too. If I can just 
look at that map. 

Be sure I get that all the way up. 
Yes. 
Okay.

Roger, Jim. We have a question that may bear on 



this minor water problem. We're wondering if you 



Tape 70/11 
Page 35T 



can tell, or have a feel, for whether you're 
in a crater, or the slope of the spacecraft is, 
perhaps, caused by just a gentle slope of the 
lurain there. Any feel for that? 



Ok 11 28 58 LMP-LM 
Ok 11 29 27 CDR-LM 
Ok 11 29 29 CC 



I'll have to ask Dave. 
Houston, Hadley. 
Go ahead. 



Ok 11 29 35 CDR-LM I guess to answer your question, we're not really 

in a big crater anjrwhere. I - I think there 
are possibly - one gear may be in one of 
these small craters. And as you might have heard 
Jim and I discussing, there's a rather high crater 
density and I guess my references to traffic - 
traf f icability were really to boialders , because 
that's what I was really most concerned with on 
driving the Ro - Rover. There is a fairly high 
crater density around. And, as I mentioned, they 
range up to probably 10-8, 10 meters or so. 
And in our local area - Let me give you a - a 
rough count of the, oh, 8- to 10-meter ones. I 
guess one every 15 to 20 meters. So there's 
a - a fair number of medixm craters . Nothing 
sharp, no boulders, and it may be that one footpad 
is in one of these craters that range on down to 
maybe 2 meters or 1 meter. And then there's 
a sharp break in craters down to probably a foot 
or so. But it - it's almost like 1^, as I 
remember their pictixres , quite a variety of crater 
sizes, up to some certain limits. I don't see 
anything on the 2 5 -meter scale that we hoped to 
expose the bedrock in our immediate vicinity, 
although I can see some fresh ones - maybe some 
rims out through the window here at 10 or 11 o'clock. 
But I can't really account for our attitude right 
now. We'll just have to get out and take a look. 

Ok 11 31 19 CC Roger, Dave. Copied all that loud and clear. I 

phrased my other question po - poorly. Apparently, 
the thermal people were worried that if you were 
sitting in - right in the bowl of a - of a fairly 
deep crater, there would be a certain focusing effect 
of the sunlight, and it may require more water to 
keep the spacecraft cool later on. That's a good 



Tape 70/12 
Page 358 



answer we have from you. Will have some more 
questions for you later on when you're comfortable 
and into your eat period, if you're in - interested 
in - in talking at that time. And we'll "be standing 

Oh 11 31 57 CDR-LM Okay, Joe. I - there's so much hfere , I could talk 

to you forever. But, there - there's a large - I 
can see now, we were in zero phase — and without 
taking a close look out the front window, I 
couldn't tell you — "but, as I was coming down 
trying to select a spot to land, I was trying to 
avoid these 8- to 10-meter craters. And we have 
one out of our k o'clock - I guess about 3 or 
k o'clock that I discussed before. There is one 
directly in front of us almost - the rim is 
almost on the shadow of the radar antenna right 
now, and it appears to be an 8- to 10-meter 
one. And there's one over to our 10 o'clock. 
They're just all over, and it was sort of hard 
to find a spot that was reaJLly level. 

oh 11 32 hi CC Roger. We copy. And, Dave. Earlier you talked 

about, specifically, a very bright crater, I 
think, fairly near by. Could you estimate for 
us the size, distance, and azimuth of that bright 
crater? 

Ol^ 11 33 03 CDR-LM Stand by. I can tell you're still looking for 

our position. 

0I4 11 33 ih CC No, that's not necessarily true. We think we're 

pretty wer - well squared away on your position. 
This probably would cinch it down, though. 

oh 11 33 25 CDR-m Okay. As we're unsuiting here, let me think that 

one over. I think we can cinch it down too. 

Oh 11 33 32 CC Roger. 

OI+ 11 33 36 CDR-LM But, before we go, I got to tell you about a - a 

rock that's right out at 12 o'clock, right - almost 
at the radar antenna shadow, and it's going to be 
gone pretty soon. There's a - a dark, black, 
angular fragment which is on the order of 
probably - I'd say 6 to 8 inches across. It's 
got some light-colored apparent dust on it . It's 



Tape 70/13

imiq.ue on the surface. All the other fragments 
appear to be white. And this one really looks like 
a Jewel. You can think about that for awhile. 

Ol+ 11 3h 12 CC Roger. We copy. And it wouldn't surprise me at 

all if there wasn't some thought given to that rock. 
And, Dave and Jim, when you're comfortable, we'll 
call up our best guess as to your position and let 
you think about that for awhile. 

Ok 11 3h 36 CDR-LM Okay. 

OU 11 3h 39 CC And you'll be very pleased to hear that your landing 

was not recorded on either of our seismometers on 
the Moon. 

oh 11 3h kg CDR-LM Well, that's nice to know. You can tell the Pro- 
gram Manager that we certainly didn't buckle his 
engine bell for him. 

Oli 11 3i* 57 CC Roger. 

ok 11 35 07 CC And, Jim, I just have to ask you, did you notice 

if the contact light came on or not? 

Ok 11 35 19 LMP-LM You didn't hear me. 

ok 11 35 28 CDR-LM Joe, I think Jim might simply qualify what he thought 

was - what our landing velocity might have been. 

ok 11 35 36 CC Roger. I'd say he was dividing everything by 10. 

And, Dave, be advised the program - - 

ok 11 35 kk LMP-IiM Ho, I don't think so. I think we're 

ok 11 35 kB CC Okay, Dave. Be advised the Program Manager says 

he'll wait until tomorrow until he decides about

it wasn't running when we touched down.

Hello, Falcon. This is Houston. Just for your 
own information, the water separator numher 1 looks 
good. But we'll he keeping a further eye on it here 
A little later on , Gordo ' s going to read up a pro- 
cedure that involves the VHF communications check. 

Okay. I understand. Thank you. 

And, Dave and Jim, we've got some positions, when 
you get in a comfortable position, maybe have some- 
thing to eat, but have your maps out. I'll read 
them up to you. 

Okay. Give us about 5 minutes. 
Roger, Dave. No hurry at all. 

Falcon, Houston. If you're not busy, I'll give 
you some switch positions to get set up for the 
VHF comm check. 

How much time do we have , Gordo? 

Plenty of time. Probably - about 15 minutes before 
he comes over the horizon. 

Okay. Give us about 5 to finish fixing dinner here. 
It takes a while. 

Okay. 

Okay, Houston. Hadley Base here. Go ahead with 
yo\ir switch settings. 

Okay, Falcon. This is Houston. You can go ahead 
and throw these switches as I call them. We'd like 
the VHF A TRAIISMITTER to VOICE, and the VHF A 
RECEIVER ON. That's a verify. Over. 



Ok 12 17 16 CDR-LM Roger. That's a verify on both. 



Tape T0/X6 
Page 362 

0I+ 12 IT 19 CC Okay. And the VHF A SQUELCH, we'd like you to ad- 

just it. Suggest so you can hear a little noise. 
And VHF ANTENNA, AFT. Over. 

Ok 12 17 32 CDR-LM SQUELCH with a little noise, and an - ANTENNA, AFT, 

Ok 12 17 35 CC Okay, the IMP. ¥e suggest he makes a check. Put 

his AUDIO panel, VHF A T/R to T/R. And we're going 
to have Al initiate the check. He - He's kind of 
"busy as he passes over, so he's going to initiate 
the check at a slack moment, and that'll be some- 
time between 108:32 and 108:l|lt. 

oh 12 18 03 CDR-LM Okay. A couple of points. We don't have any mis- 
sion timer, and we'll be standing by. And I'll have 
to do it, because we have one lightweight headset 
that - that would - that failed right when we picked 
it up after lift-off when we first unstowed it. We 
brought it down so Al could have a good one. 

Qlt 12 18 22 CC Oh, okay. Fine. We think we know what the problem 

was. We think it's Just an error in procedures at - 
back before PDI. And before the comm check you were 
in VOICE/RANGE, according to the Timeline Book, and 
that would block your transmitter . And that ' s 
probably what's wrong. We really don't suspect any 
hardware problem. 

OI+ 12 19 03 CDR-LM Okay. We Just talked it over, Gordo. After the 

radar check, we went from VOICE/RANGE back to VOICE 
on the VHF A. 

ok 12 19 17 CC Yes, we realize that. But we think that the comm 

check was before that - that you got back and that 
you just never did have another call after you got 
back to VOICE. The blocking - that was my mistake 
a minute ago - the block was due to the blocking 
of your receiver while in ranging. Over. 

Ok 12 19 k2 CDR-LM Okay. Well, we're set up now, and Jim's got his 

camn helmet on. So we'll be standing by for Al's 
call. 

Ok 12 19 kQ CC Okay. Good enough. 

0^* 12 19 56 CDR-LM And, Houston. Hadley Base, here. Anytime you want 

to discuss the landing and our position, why, I 
guess we've got supper cooked, and we're ready. 



Tape 70/17 
Page 363 



oh 12 20 06 CC Roger. Under - understaiid that supper is cooked or 

"being eaten? 

oh 12 20 15 CDR-LM Yes, if you like cold tomato soup. 



oh 12 20 23 CC Oh, mercy, yes. Delicious. Dave, I guess the 

first thing that we might start with, is our esti- 
mated position of your landing sight. And we've 
got two inputs on that. Al, when he passed over, 
got what seemed like a pretty accurate hack on 
where you've landed, and he calls it out as Bravo, 
Romeo 2 - Correction. Disregard. Bravo Romeo 5 
75 5. And In the back room, the "best guess from 
the back room is Bravo Romeo 2 75 2. In both cases, 
it's very near November Crater. It's just a q.ues- 
tion of on which side of November are you now sit- 
ting. So a tally ho on November Crater will tell 
us, I guess, exactly. As it is, we think we know 
where you are to within about 100 - 100 yards. Over. 

OU 12 21 28 CDR-LM Okay. I tried to find November Crater out there, 

Joe. And, 1 could see a fresh one to the north of 
. . . rim, but no bright ejecta, as you see on the map 
there. But I guess I probably agree with you, and 
I might run through what I saw from pitchover, on 
down, and that might help you out a little bit. It 
was quite a surprise. 

oh 12 21 52 CC Roger, Dave. We're standing by. And - and by the 

way, your coram is absolutely crystal clear. It's 
Just beautiful. 



ok 12 22 Oit CDR-LM Great. So is yours. Well, anyway, I got the 3000- 

south call, -which was a good call. And as we cant? 
down prior to P6U, I could see the rille to the 
south, and I couldn't see it up over the nose. And 
I got the distinct im - impression, as I looked at 
Hadley Delta, coming into P6it, that we were going 
to be way long. And, I guess - you know, I've never 
shot one of these landings before , and I got fooled 
a little bit there. And at pitchover, we were def- 
initely quite a ways south, and I never saw Index 
Crater all the way down. I saw what I thought was 
Salyut, and the one north of Salyut , which I sort of 
picked as a landmark to zero in on. I gave about 
fovr clicks right and then about two more right , as 
I remember, to get us back up to the north. And be- 
cause we were south, I lost the - the four craters in 
a row that lead into Index. But I believe the topo 



Tape 70/18 
Page 36 14 



relief is somewhat exaggerated in that our - our maps 
and models show good shadow at Index. And, as good 
a crater as that is from orbit — it was very easy 
to pick, up in orbit — I never did locate it on the 
descent during the visibility phase. But I - I was 
able to see earthlight, and that substantiated your 
call of being 3000 short. Now, after I got over a - 
a roll to come back up north with the LPDs, and 
Salyut — what I thought was Salyut — I redesignated 
short to bring us back to what looked like a reason- 
ably smooth area. And then I just picked out a spot 
in between the holes down here, and I - put it down. 
And I guess I - I sort of have to agree with you 
that we're probably somewhere around November. And - 
let me think a little bit and see if I can remember 
seeing something that looked like November. 

oil 12 2h k2 CC Roger, Dave. We copy that. 

oh 12 2k 1+6 CC Dave. While you're thinking there, let me repeat a 

question I asked earlier. You described a bright - 
a very bright crater in one of your first descrip- 
tions. And we were - we're still looking for the 
azimuth, approximate distance, and size of that 
bright crater. 

OI+ 12 25 09 GDR-IAl Well, the brightest crater I've seen is the one 

that was right on the rim, halfway up St. George, 
and it's almost white. And - is that the one you're 
thinking about? 

OU 12 25 25 CC Stand by, Dave. I think there - I think there was 

another one. I'll - I'll get back with you on that 
in a minute. It was one that was a lot closer to 
you. And I've got another question now on the board 
in ftont of me here. We - we think you're near the 
edge of Aristillus - Aristarchus ray. And, I wonder 
if you can recall anything about the local albedo 
changes . Over . 

Ok 12 26 02 CDR-UVI No, Joe, I didn't see a thing. And, it's just all 

the same (laughing), north and south, east or west 
in our current position. 

Ok 12 26 23 CC Roger, Dave. Copy that. And sorry on that crater 

call. That was fault - Arist - the Aristillus - 
Autolycus ray.

Dave, while you're sipping your - cold tomato soup 
there, was the black rock that you called out to us 
on a crater rim? 

Yes, it is, Joe. It sure is. And it's a typical 
crater to see. It's quite a suhtle crater, but it's 
out - well, LM shadow being like 30, maybe 28 meters 
now. It's probably about 1+0 meters away, the rim 
of the crater. And that black rock is sitting right 
on the rim. 

Roger. 

Hey, Joe. Jim's just pointed out another black one 
now that must be 300 meters out . And it ' s so dark 
that it looks like a shadow. It's just coai black, 
and it looks like it might be about the same size. 

Roger, Dave. Incredible. While you're peeking out 
there, do you have any further observations on the 
aboindance, size, and distribution of the frags in 
the nearby field of view? 

Yes, That's what we found here. Yes, I'd say 
that, in the - in the near field, the surface is 
covered by - probably less than 1 percent of frag- 
mental debris. And, of that debris, I'd say 70 per- 
cent of it is on the order of an inch to 2 inches , 
or less. And maybe the other 30 percent seems to 
be in a range of maybe 1+ or 5 inches , something like 
that; no large frags anywhere. They mostly - - 

Dave. Let me interrupt a second. Verify - - 

- - colors.

That's verify. 

Thank you. Continue. 

Okay. Most the fragments are light colored, except 
for the two that we - we mentioned to you. In fact,

that are Just stark white and some that are a lighter 
gray.

run the comm check coining up here, hut we'd like to 
go ahead and get the - the procedures here in the 
Flight Plan as we go, and I'll give you a hack be- 
fore the pan camera start time. The pan camera

we're going to use nominal procedures. Over.

and the VHF ANTENNA to RIGHT. Over. 

oh 12 10 05 CMP Okay. Understand VHF A, SIMPLEX, and ANTENNA, RIGHT. 

oh 12 10 09 CC Okay. And then check on whatever audio panel you're 

using, probably 9, that VHP AM T/R is at T/R. 

oh 12 10 21 CMP Roger. That's verified. 

oh 12 10 23 CC Okay. That's all there is imtil about 108:32, which 

time I'll call you. And then any time in about a 
12-minute band there, you can initiate a VHF comm 
check when it doesn't interfere with the photo tar- 
get there.

I'll give you a hack when you're within range of

Roger , 

Endeavour, Houston. Reminder: about - slightly 
less than k minutes now to T-start for the pan 
camera. 

Roger , Houst on . 

Hoiist on , Ende avour . 

Endeavour, Houston. Did you call? 

Roger, Houston. Just reporting that the GAMMA RAY 
BOOM RETRACT time was 3 plus 07. 

Roger; 3 plus 07- 

Endeavour, Houston. Don't bother to acknowledge; 
15 seconds to pan camera T-start. 

Endeavoiir, Houston. Would you verify that the 
MAPPING CAMERA IMAGE MOTION switch was to INCREASE? 
Over. 

Hotiston, Endeavour. That's verified. 

Okay. You got it a couple of minutes ago, is that 
right? 

Yes, that's right, Gordo. At 21. 

Okay, fine. It looked funny on the data here. I'll 
check. 

Houst on , Ende avour . 

Endeavour, Houston. Go ahead. 

Okay, Houston. Gordo, I'm Just coming up over 
Le Monnier now. Heading towsirds Serenitatis , and 
finished that photo strip from Peirce to Le Monnier. 
You might tell the king that the strip looks pretty 
good. I got some convergent stereo on Romer on the 
way over. And right now, I'm directly above one of 
the Llttrow ridges, and it's - it - it has quite 



Tape 70/2lt 
Page 370 



distinct relief. I'm really surprised at the amount 
of relief that the ridge has from here, and I won't 
take a picture of it, because we got a couple yes- 
terday. But it's really quite distinct. And I can 
look out to the north and look at Posidonius . And 
there's a very - along the - the narrow portion of 
what looks like the - the lakebed part of the fill 
in the mare floor, it looks very similar to what 
you'd see on a lakeshore. Very distinctive color, 
light color on the "bank , and a darker color in the 
mare floor, and what looks like some very positive 
relief, almost as if there was a lava flow that 
came out around the edge of the slab that was tilted 
and flowed down into the low spot of the floor.

APOLLO 15 AIR-TO-GROUND VOICE TRAHSCRIPTION 



Ok 12 30 36 CDR-LM Okay, we heard that. Gee, I'm Just looking down 

right in front of the LM here to try and get your 
relative abundajice, and I was about ready to say 
that maybe, of these inch frags, there might be 
five or six in a square meter. And I see what 
appears to be a roimd glassy ball. It's shiny, 
it casts a rounded shadow, and it looks about the 
size - oh, maybe an - an inch or so. 

oh 12 31 08 CC Roger. 

ok 12 31 11 CDR-LM I can see some lineaments on the surface which 

appear to be from the descent engine. They radiate 
away from our position here. We'll take a closer 
look at those later. 

0*+ 12 31 22 CC Roger, Dave. And, for the benefit of our fine 

Flight Director, maybe the name of that should be 
called an Aggie. 

ok 12 31 k2 CDR-LM Okay, Joe. We'll call that one our first Aggie. 

ok 12 31 k6 CC And, Dave, the question on the bright crater, you 

described it as the one near the LM with lighter 
gray debris in it. And I'm - I'm sitting here 
wondering if maybe that was No - - 

Oi+ 12 32 01 CDR-LM Roger. 

Ok 12 32 02 CC November Crater itself. 

O^t 12 32 06 CDR-LM Okay; there was one in that fresh debris. Light 

colored around the rim. Although it was - did 
not have a particularly raised rim. It was a - a 
level rim, but there was a - a fair amount of debris 
around the rim. And that was out about, my 2 o'clock, 
I guess. Maybe you'd call that November. I guess 
what I was looking for, relative to November, was 
the bright ejecta blanket, which I don't really see. 

ok 12 32 3U CC Roger. We agree. It does look bright on our map 

here. Stand by for a call from Al if you could, 
guys .

Ol; 12 32 U5 CDR-LM Roger. 

'ih 12 33 07 CC Falcon, would you give Endeavour a call? He's 

been calling you. Evidently you don't read. Tiy 
it in the reverse. 

Ol* 12 33 15 CDR-LM Hello, Endeavour. This is the Falcon. How do you 

read? 

ok 12 33 28 CC Falcon and Endeavour, this is Houston. Evidently 

neither of you are reading each other. We'll stand 
by until you get overhead and give it another try. 
I'll give you a cue. Over. 

Ok 12 33 h3 CDR-LM Falcon. Roger. 

oh 12 33 h9 CC And, Falcon; this is Houston. We're suggesting 

that you proceed on with the PLSS charge, and we'll 
be saying goodnight to you shortly. You're 
coming up on yoior sleep period shortly. 

Oh 12 31+ Ok CDR-LM Okay. And did that Sun compass do you any good, 

Joe? 

Ok 12 3^+ 12 CC Dave, those - those readings converge pretty well. 

They just don't decide between the about 100-meter 
error we think we have in the two possible landing 
sites. But you're veiy close to being exactly right 
on. 

Ok 12 3k 30 CDR-LM Okay, fine. 

ok 12 35 ok CDR-LM Hello, Endeavour; this is Falcon. You're loud and 

clear. How us? - Hey, it was super, just super. 
And we got the greatest place on the Moon down 
here. Yes, that's what they tell me. Say, can you 
see Index, very well up there? 

OI+ 12 36 1I+ CC And, Falcon, this is Houston. In a few minutes, 

while you're stowing the ETB, we'd like for you to 
pick up the magazine and frame counts on the magazine 
from your two cameras, please. 



Ok 12 38 Ik CDR-LM 



Well, we'll do the little things and you do the 
big things. 



Tape Tl/3

OU 12 38 18 CMP Yes, sirree. Maybe we cein get together and 

compare notes . 

oil 12 38 25 CDR-LM Okay, we're about ready to power down for the 

night, and everything's in good shape down here. 
Everything is running well. And all we got to do 
is get a little sleep and get out after it. 

Oh 12 38 36 CMP Okay, David. See you in the morning. 

oh 12 38 38 CDR-LM Okay. Have a nice night . 

Ql; 12 38 h2 LMP-LM Good night, Al.

WELrm for you, Jim.

oh 12 hi 11 CC Thank you, Dave. We're hearing him. 

Qlt 12 Ul 20 CMP What is it? Shift change, Joe? 

oh 12 Ul 22 CC Al, no, it's not. I think maybe - we may be on 

split S-band, and you're transmitting to me instead 
of Gordo. What can I do for you? 

Oh 12 Ul 37 CMP Well, I didn't - I didn't change my frequency, Joe. 

Say listen, I had a photo pass - - 

Oh 12 hi 51 CC Alfredo, are you still reading me? 

Oh 12 h2 09 CDR-LM Say, Houston; Falcon. By the way, the VHP is 

crystal clear up here. Our comm is working great. 
Soon as you guys get it squared away on the ground, 
I guess we'll all be tied together.

Ok 12 k2 19 CC Roger, Dave. We - we read the conversation. We'll 

be standing by for a report of a successful PLSS 
charge and interested in getting you g^ys in the 
sack as quickly as possible. Also, when you load 
up the ETB, we'll be standing by for frame coimts 
from your cameras . 

Olt 12 k2 ho CDR-LM Wilco.

for you.

beautiful shots already. 

Ok 12 1+5 07 LMP-LM Beautiful scenery. 

Ok 12 U5 11 CC It sounds it. 

Ok 12 52 37 CC Hello, Hadley Base; this is Houston. Regarding the 

water separator number 1: Jxist to give you a warm 
feeling, it's - it's working perfectly now. It 

looks as though we just had a temporary - temporarily 
there, some water run down from the hoses and 
waterlogged it, but it's working perfectly now. 
Over. 

Ok 12 53 02 CDR-LM Okay, Houston. Thank you for passing it on. 
Ok 12 59 36 CDR-LM Houston, Hadley. 
Qlt 12 59 39 CC Go ahead, Dave. 

Ok 12 59 1+5 CDR-LM I'd like to confirm that, on the LMP camera for EVA- 

1, we use MAG Lima. Is that correct? 

Ok 12 59 53 CC That's correct, Dave. MAG Lima on the LMP camera. 

And we copied all the frame counts. 



Ok 13 00 02 CDR-LM 



Okay; thank you. 



Tape Tl/5

OU 13 00 33 CC And, Dave, this is Houston. Did you copy from 

me that yoiir water separator number 1 looks good 
again? 

OU 13 00 U3 CDR-LM Roger; I thought we called you "back on that, Joe. 

We got it. Thank you. 

Ol+ 13 08 08 CDR-LM Okay, Houston. Hadley Base has two charged PLSSs . 

Ok 13 08 l6 CC Go ahead, Dave. 

Ok 13 08 20 CDR-LM Roger. We have two charged PLSSs. 
0i+ 13 08 23 CC Roger; that sounds good. 

0l+ 13 08 52 CC And, Dave and Jim; this is Houston. If you two are 

interested, I could probably arrange for a geology 
lecture here to put you asleep - to put you to sleep. 

OU 13 09 10 CDR-LM Perhaps, Joe - I'm afraid that might - that'd 

keep us awake. 

ok 13 09 ik CC Roger. I agree. That was an outstanding job of 

describing your surroundings. By the way, guys, 
I'm really - all of us are looking forward to 
tomorrow. 

Ok 13 09 27 CDR-LM Well, thank you, Joe. I hope we get wound up and 

get out there smd get close to some of this. It's 
really fascinating. 

OU 13 13 Ik CC Hadley Base, this is Houston. Requesting telementry 

switch. LO bit - bit rate. Please. 

Ol* 13 13 26 CDR-LM Roger. LO bit rate. 

OU 13 19 37 CC Hello, Hadley Base. This is Houston. 

ok 13 19 k3 CDR-LM Go ahead, Hoxaston. 

ok 13 19 kj CC Roger, Dave. We're not going to ask exactly for a 

mark when you ingress the hajumocks. And, by the 
way, I think the space program is the any - only 
place where a person can ingress a hammock, but 
we would like a status report on the two of you 



Tape 71/6 
Page 376 



when you get comfortable. And, a final thing, you 
might be interested, the score of the All Star 
game at about halftime is the Baltimore Colts ihj 
College All Stars 7. And we'll be standing by for 
your status report. Over. 

Oi+ 13 20 27 CDR-LM Okay. That sounds like a pretty good game. 

Ql* 13 28 10 CC Hadley Base, this is Houston. 

Oi+ 13 28 17 CDR-LM Gk), Houston. 

Oil 13 28 18 CC Dave, before you get too well settled there, I 

forgot to indicate that the Surgeon is requesting 
a - a radiation device read-out to be included in 
your crew status report there. 

Ok 13 28 3k CDR-LM All right. We'll look into that, Joe. We'll get 

it. 

oil 13 28 38 CC Okay. Fine, Dave. I was afraid you would get in 

a position where you couldn't reach those devices. 

Ok 13 28 k8 CDR-LM Oh, no, we weren't thinking of passing the Surgeon. 

We just have a - a number of unscheduled housekeeping 
chores that we've got to get squared away here, if 
we are going to settle down for 3 days. 

Ol* 13 29 00 CC Roger. Understand. And we're in no hurry. I do 

want you to get a good night's rest though. 

Oil 13 29 10 CDR-LM Roger. 

Oil 13 29 3I1 CC And, Dave, this is Houston. It sounds like you'll 

be able to carry out a very good experiment with 
your portable Leaning Tower of Pisa there. 

01+ 13 29 50 CDR-LM Well, I'll tell you. It really doesn't seem to 

be leaning that much. We haven't noticed any 
- well, we can see it's still a little tilted here, 
but it's no real problem. 

Oil 13 29 59 CC Roger. 

Oh 13 30 06 CDR-LM In fact, what, about 10 degrees at the most? 



Tape Tl/T

Oh 13 30 20 CDR-LM Okay. On the PRD, if you're ready to copy. 
Oi+ 13 30 25 CC Roger; go ahead. 

Ok 13 30 30 CDR-LM Okay; CDR is 25011. The IMP, 08020. 
0l+ 13 30 39 CC Roger, Dave. Thank you. 

oh 13 36 l6 CC Dave, this is Houston. 

OU 13 36 23 CDR-LM Go ahead. 

oh 13 36 25 CC Roger. Apologize for the q.uestion. But are your 

radiation meters tucked away yet? 

oh 13 36 35 CDR-LM They sure are. 

OU 13 36 37 CC Okay, thank you. 

Oil 13 36 hi CDR-LM Roger. 

ok 13 1+3 39 CC Hello, Hadley Base; this is Houston. Over. 

OI+ 13 h3 h6 CDR-LM Go ahead, Joe. 

ok 13 h3 50 CC Roger - - 

Oh 13 1+3 51 CDR-LM What can I do for you? 

oh 13 1+3 52 CC Roger, Dave. We've got two goodnight questions for 

you here. The first, we're trying to unravel some 
water-press lore data, and we just needed to know if 
you charged the PLSSs, using your checklist or using 
the decal instructions on the PLSSs. Over. 

ok 13 hh 16 CDR-LM No, we used the checklist. We used the checklist 

for the water . . . 

q]^ 13 kh 22 CC Roger; understand you used the checklist and charged 

it with water for the specified 5 minutes then. 
Over. 

Ok 13 hh 35 CDR-LM Yes, that's correct. 

oh 13 hh 37 CC Okay; copy that. And, Dave, we've got a major 

discrepancy in your radiation dosimeter reading. 
It's either gone belly-up on us or we miscopied 
the numher which you read. We'll have to ask you 
to read it again, please.

You know that we switched them? 
Say again. Falcon. 

You know that CDR and CMP's PRD's were interchanged. 

That's affirm, Dave; and the last reading we got 
from Al was considerably higher than the one we got 
from you. The device is either broken or you're 
being \m-irradlated, which seems unreasonable. 
Over. 

Well, all I can do is look in this very tiny window 
and look at these very tiny numbers and they say 
2501 - I guess I can give you a seven on that one. 

Roger. Everybody's happy. Thank you, Dave. And 
we have no questions from Houston. We'll say a 
pleasant good night to the two of you and look 
forward to tomorrow. Over. 

Okay, Joe. I guess we don't have any alarm clock, 
so if somebody' 11 give us the word, we'll be 
standing by. 

I wouldn't be at all surprised. You're liable to 
get the word from down here. And it's been an out- 
standing day. 

Yes , we ' ve en j oy ed it . 

Houston, Hadley Base. We're all tucked in. We'll 
see you in the morning. 

Falcon, Houston. Did you call? 

Roger. I just let you know that we're all tucked 

in - in the hammocks, and we'll see you in the morning. 

Roger, Dave. Good night and don't fall out. 

No way. Bob, no way. There's no place to go if I

Yes, we got the ones you passed to Houston, and we 
also got the ones in the back room, and I guess

to ask you for a crew status report. Over. 

oh 13 11 31 CMP Okay. The E-MOD 's coming your way, and stand by a 

minute and I'll give you all the status. 

Oh 13 11 37 CC Okay. 

OU 13 11 ^+7 CMP I guess just - if you want just crew status report 

- doing just fine. I don't know what else I can 
say. 

O^t 13 12 00 CC Can you give us how much sleep you got last night, 

and also your PRD read- out? 

oh 13 12 10 CMP Okay. I've got apparently a bad PRD, so I haven't 

been keeping track, but I will if you want. But I've 
got Dave's PRD. And, let's see, I guess you didn't 
get a status report this morning. I got - I think 
all three of us got 7 and a half hours of sleep 
last night , and I got mine all in one segment . And 
I've taken no medication today. 

oh 13 12 32 CC Okay, Al. Fine. That - that was the problem; we 

didn't get this morning's report. One other quicky. 
If you'll comment if we're throwing too many 
reminders up from the ground here or not enough. 
We're just trying to get a feel for whether we're 
harassing you or helping you - on the timing 
callouts . 

oh 13 12 53 CMP Gordo, I think - Yes, yes. I think if you don't 

expect me to answer, it's a great help to me, 
because I do find that I'm trying to be three 
places at once in here; and, if I'm doing a P52 , 
I can't be over working the - the SIM bay at the 
same time. So the reminder is good. I can always 
break into a P52 to go turn something off, but 
bearing in mind that I don't have a mission timer 
in - in the lower equipment bay, it's a little 
difficiilt for me to keep tract of the time sometimes, 
so 1 do appreciate it. 



Tape 71/16

Ok 13 13 27 CC Okay. We'll keep them coming. If they, at any 

time, become too much. Just shut us up.

they were all nominal, just say so, and we'll get 
them some time later. And that's about euLl we have 
for you until tomorrow morning. Over. 

oh 13 15 33 CMP Okay. Onboard read-outs: BAT C was 37; PYRO BAT A 

was 37; PYRO BAT B, 3T; RCS Alfa was 73; Bravo, 71; 
Charlie, 72; and Delta, 73.

running behind on his DSE rewind; if it's not 
rewoiind when you LOS, you'll have to do those - 
perform all those verifies yourself. Over.

Ol+ 19 30 39 CC Falcon, Houston. Over. 

OU 19 30 CDR-LM Hello, Houston. This is Falcon. Go. 

ok 19 31 01 CC Roger. Morning, Dave. WaJting you up an hour 

early because we've got a little problem on board 
we need addressed. When you get a moment to get 
something to write it down, let me talk to you 
about it in detail. The problem we're looking at 
is a leak in descent 0^, and we're trying to 

determine whether we got a small cabin leak or a 
leak in the oxygen system itself. Over. 

Oh 19 31 28 CDR-LM Okay. Understand, Bob. 

Ok 19 32 ~ BEGIN LUNAR REV 20 

0^4 19 35 53 CC Falcon, Houston. Are you ready to copy? 

OU 19 36 02 CDR-LM Stand by, Houston. 

Oh 19 36 h3 LMP-LM Houston, this is Hadley. We're ready to copy. 

Oh 19 36 U8 CC Okay, Hadley. First thing we'd like is HI bit 

rate. That will allow us to look at some extra 
parameters, particularly temperature, to see how 
much of this fall is due to temperature effects, 
which we haven't experienced before. So, if you're 
standing right there, why don't you flip that on 
while I read you the rest of the pad, Jim. 

Oh 19 37 09 LMP-LM Okay. We're HI bit rate. 

OU 19 37 11 CC Roger. Thank you. Next step is DESCENT 0^ to 

CLOSE. And why don't you do that now, because the 
step following that is for the ground to monitor 
the descent 0^ tank pressure and the cabin pressure, 

and we're going to look and see if the leak, which 
we've seen so far as a drop in the tank pressure, 
is due to a cabin leak or to a leak in the system 
itself. Copy? 

Ok 19 37 U5 LMP-LM Okay. I copy. DESCENT 0^ is CLOSED. 



Tape- V^I2 
Vaffe. 'i9h 



Oh 19 37 51 CC Roger. Stand by. 

Oh 19 38 10 GC Okay, Hadley. We'll be watching that. Then, you 

might copy down the following steps to be per- 
formed, depending upon our analysis of what we're 
watching right now. One, if leak stops, upper 
and forward hatch valves, close. And ensure that 
the urine QD is capped. Over. 

Oh 19 38 52 LMP-LM Stand by 1. 

oh 19 39 17 LMP-LM Houston, this is 15. We were just looking at the 

urine transfer device, and that valve was in the 
OPEN position, although the device wasn't capped. 

Oh 19 39 31 CC Roger. Copy and understand that the receptacle or 

transfer device was attached to the hose . . . all 
night . 

Oh 19 39 h2 LMP-LM That's affirm. 
Oh 19 39 h3 CC Roger. Stand by. 

Oh 19 ho 2h CC Okay, Jim. We'd like you to leave it in the con- 

figuration you found it in for a few minutes , 
because that will allow us to verify that that's 
where the leak was. Over. 

Oh 19 ho 37 LMP-LM Okay. I'm going to open the valve again. 

Oh 19 ho ho CC Roger. Thank you. I'll tell you, that's good 

news if that's what it is, man. 

Oh 19 ho k6 LMP-LM Understand on your first - Okay, on that first 

step that you read, it said, if leak stops, to 
close both dump valves. 

Oh 19 1*0 57 CC Roger. That's affirm. In other words, if we see 

that the lesik has stopped here on th& ground, we 
will then ask you to close both dump valves and 
also verifying the urine QD; and, if the leak in 
the cabin - now, if the cabin is completely 
isolated - continues to hold, we will then ask 
you to open the hatch valves one at a time to 
verify that the hatch valves are not going to 
leak or which hatch valve is leaking in the open 
position. Some of that will be - not indicated, if 
indeed it is the urine QD that's capped. Do you 
copy, Jim? 



Tape 75/3

Ok 19 Ul kk LMP-LM Okay. Yes. We understand. 

O^t 19 Ul k6 CC Roger. And we'd like to verify right now Just 

quickly that the DESCENT 0^ is CLOSED; that the 

urine receptacle is back in its original configu- 
ration, bver. 

Oh 19 1+2 02 LMP-LM That's verified. 

ok 19 k2 03 CC Roger. Let's just stand hy here for a couple of

tell us. 

Ok 19 k2 13 LMP-LM Roger. 

ok 19 k2 30 LMP-LM Bob, as long as we're talking about consumables, 

what are you showing down there for water? Because 
we are reading - oh, about 60 percent on descent 1 
and 2 now. 

Ok 19 k3 13 CC Stand by, Jim. We'd better read our decals down 

here, too. 

OU 19 k3 25 LMP-LM Bob, you did copy my question about the water 

quantity? 

Ok 19 U3 29 CC Roger, Jim. And we're having to read our decals 

down here, too. It will taJte us a minute. We'll 
be right back with you. 

Ok 19 k3 38 LMP-LM Understand. 

ok 19 k6 52 CC Jim, we have an answer for you on your water gu 

problem. The 60 that you're seeing indeed cor- 
responds to a true 70 percent which, indeed, is the 
number that we were expecting to see. Over. 

ok 19 1*7 09 LMP-LM Okay. Fine, Bob. Thank you.

Olt 19 1;9 02 CC Roger. It looks like your descent tanks are 

holding up very nicely; your cabin is falling 
slightly, as you may have noticed already on 
your - your meters. We would like you to take the 



Tape 75/^

urine receptacle off the hose and then put the 
QD cap on after you remove the urine receptacle. 
Over - And then we'll - After you have done this, 
we will watch the cabin for a little bit longer 
to see that it stops also. Over. 

Ok 19 kg 29 LMP-LM Okay. That's in work. 

Ok 19 k9 1*8 LMP-LM Okay. The urine receptacle is off, but the - 

the other QP is - installed.

down - down here on the ground. 

Ok 19 50 1+2 CC And, Jim, we'll be sitting here in this configura-

Olt 19 50 51 LMP-LM Roger.

there for a while, Jim.

good sleep there- 

Ok 19 51 11 LMP-LM Yes, sir. That's the best sleep I've had on the 

flight. 

Ok 19 51 13 CC Roger. How was Dave doing? 

Ok 19 51 2I+ CDR-LM Just fine. Bob. I was - way down in sleep when 

you gave us a call. 

Ok 19 51 29 CC Sorry about that, Dave. 

OI+ 19 51 3^ CDR-LM Oh, no. That's okay. Let's get the problem 

squared away. 

Ok 19 51 38 CC Yes, I figured we lost a little bit of sleep down 

here on the ground tonight, I couldn't even fall 
asleep at my console. 

ok 19 51 1+7 LMP-LM That is amazing.

12l+:25:21; 126:23:32; 128:21:1+1|; and 130:19:51+. 



Roger. Good readback, Jim. 

And, if you have the consumables update, I'll 
take that, too. 

Roger, Jim. We're ahead of ourselves there. 
Okay. Not - no rush. 

And, Falcon; Houston. Over. We believe that we 
are very strongly convinced, finally, down here, 
that that indeed solves the problem. You can go 
back to DESCENT 0^, OPEN. And we'd like to suggest 

that the procedure, when using that particular 
device from now on, will be to remove the 
resepricle [sic] when you're finished and cap it 
in - as we've just done. Over. 

That's good news. Bob. We'll do that. And, gee, 
the sleeping up here is really good up here; and. 
If y'all ever see another little problem like that, 
why, we'd be only to happy to roll over and take 
care of it. I think, as a matter of fact, we 'a 
even sleep better if we knew that you wouldn't 
mind waking us. 

Roger. You can sleep better because now you know 
I can wake you up anyway. The thing didn't drop 
out of your ear, apparently, Dave. 

Oh, no. I made sure of that. 

And you guys have about 22 minutes left , if you 
want to go back to sleep again. 

Well, I tell you, we probably could. We were just 
talking - talking it over, and both of us slept just 
as well here as we do at home. 



Tape 75/6 
Page 398 



OU 20 03 Ok CC Well, frankly, Dave, it's your guys option. If 

you want to lie down and take a little morning 
snooze while the rest of us keep working down 
here, that's your option. I'm not sure that we 
want to - we weren' t talking about starting the 
EVA early. I think that was kind of agreed upon 
■before - we start on time, wasn't it? 

Oh 20 03 23 CDR-LM Yes, that's right. We don't want to start the EVA 

early. We'll stick to the time line. But I think 
we'll take advantage of the extra little hit of 
time here to keep getting organized. It takes a 
little while to settle down and get a system here 
for living to he efficient, and I think we can 
make good use of the time. 

Ok 20 03 k± CC Okay; you're the "boss. 

Ok 20 03 50 CDR-LM Well, we both feel pretty well rested at this 

point. And we'll just mush along here at a nice 
easy pace and, hopefully, be all ready by the 
time it's time to go out. 

ok 20 ok 02 CC Okay; and when you're ready, you can give me call, 

when you're ready for some updates, particularly 
concerning EVA planning, and I'll have a few good 
words to pass you then, when you're con - when 
it ' s convenient . 

Ol; 20 Ok 18 CDR-LM Okay. We'll get breakfast cooking here, and give 

you a call. 

Ok 20 Oi* 22 CC Roger. 

ok 20 11 21 CDR-LM Houston; Hadley Base. We've got another little 

question here on your questioning last night during 
the PLSS recharge of the water. You seem to have 
had some question as to whether we ran 5 minutes 
or not, and I wonder if you had any indication we 
got less than a full charge on the PLSS. 

OI+ 20 11 39 CC Okay, Dave. Stand by. I'll check - 

Ok 20 13 32 CC And, Falcon; Houston. I guess last night the 

question came down to whether we could read it 
well enough down here on the ground. To the best 
of our ability down here to read this, you got a 



Tape 75/7 
Page 399 



full charge, "but apparently that's plus or minus 
alsout a pound. But our readings down here, for 
what they're worth, say you got a good charge. 
Over. 



ok 20 13 57 CDR-LM Okay. Understand. We felt like we did by looking 

at the sight gages, although on the first PLSS, 
there were still a few little "bubhles running 
through when we reached the MAX time, by looking 
at the sight gage. And on the second PLSS, it 
was clear, oh, within U or 5 seconds. 



Ok 20 ik 17 CC 



Copy. 



Ok 20 19 13 CC 



Hadley Base, Houston. Over, 



ok 20 19 19 CDR-LM Go ahead. 



Ok 20 19 20 CC 



Roger, Dave. It looks like we can tell you that, 
at the present time, our extrapolations indicate 
we'll have sufficient oxygen for a completely 
nominal mission, including the PLSS recharge on 
EVA-3. This PLSS recharge - having high enough 
pressure for the PLSS recheirge - was our hardest 
constraint, and it looks like we meet it, although 
rather closely. Over. 



ok 20 19 kg CDR-LM Okay. Well, we'll breathe slowly and save as 

much as we can. 

OU 20 19 5k CC Copy. 

Ok 20 21 23 CDR-LM Houston, Hadley. We've got another question f^ 

you, since we're sitting here eating and looking 
around. Did you all, by chance, get any figures 
on our descent rate at touchdown? We're Just 
taking a look out here, and it looks like we may 
have stroked a gear some; and, as near as we can 
recall, we were coming down about a foot per second 
when we got the contact, and we just wondered if 
you had any data on that yet. 

0^ 20 22 ik CC Stand by, Dave. We're getting that. 

Ok 20 22 20 CDR-LM Okay.

Okay, Dave. We have an answer for you; which is 
that we were allowing .7 feet per second up to 
touchdown. And then at touchdown, it appears 
that, at the same point we got the roll and pitch, 
that we picked up to something like 3-7 feet per 
second at that point. Over. 

So we went from .7 to 3.7 from contact to touch- 
down. Is that right? 

Dave, we're having to look at these based upon 
times - We don't see the contact light, and we 
don't really know when touchdown occurred, but 
we're looking at things like the times. You 
were coming down at .7 there, all the way to the 
very end; and, then, at the same that we see the 
pitchup and the rollover, we see an increase 
suddenly to 3.7. Over . 

Oh, I see. Think we might have stuck our rear 
paw [sic] in a crater back there somewhere, huh? 

What say again, Dave? 

Looks like we might have stuck the rear pad in a 
crater back there somewhere, huh? 

Either that, or you touched down on something and 
fell throiagh. 

That's an interesting thought. 

Well, that says the landing radar is pretty good 
data then. 



Oh 20 26 11 CDR-LM 



Oh 20 26 23 CC 



Okay, Houston. Hadley Base, here. We're ready 
to talk over the EVA plan with you, if you'd like. 

Roger, Dave. We're ready to. First of all, we'll 
talk about the changes in the traverse plan, which 
are very minimal . But for your planning , we ' re 
now showing a LM location on the grid map in the 
coordinates of Bravo Romeo 3 and 75.5. Over. 



Oh 20 26 5^ mP-LM 



Okay, Bob. We're going to have to get in the ETB 
and pull the maps out. Just a second. 



Tape T6/2 
Pa^e 1*02 



OU 20 26 59 CC Roger. I'll wait then. 

ok 20 27 52 LMP-LM Bob, will you give me the coordinates again? 

Ok 20 27 55 CC Roger. Bravo Romeo 3, 75-5. Over. 

Ok 20 28 07 IMP-IM Roger. Copy. Bravo Rcmeo 3, 75-5- 

Ol; 20 28 12 CC Roger. And that's over there near - near November. 

Okay. That's to write down. The rest of this, 
for a while anyway, is kind of just advisory. 
This new location adds approximately 0.6 kilometers 
to the EVA-1 traverse and, therefore, about 6 
minutes driving time. However, that's only 
provisionary, of course, and our indications of 
a beautiful flat plain out there may mean that 
we'll make up some of that time just in being 
able to drive faster than we were perhaps 
anticipating. If this is not the case - - 

ok 20 28 53 mP-LM There, you have it. 

Ok 20 29 00 CC Go ahead. 

ok 20 29 02 CDR-M Before you get too far into that broad, flat plain 

out there , I hope we made it clear that there is a 
fairly good population of craters, which we're going 
to probably have to drive around. Even though there 
are no boulders, we're still going to have somewhat 
of a wander factor in avoiding the 3- to i+-meter 
craxers . 

Ok 20 29 2k CC Okay. We realize that, Dave; and, in order to 

keep the EVA total time to the maximum of 7 hours , 
this 6 minutes of it has already been deleted 
from the activities of the LM at the end of the 
traverse. So that's where we've taken up the 
slack at the present time. And then beyond that, 
no further changes have been made to the EVA-1 
time line. Over. 



0I4 20 29 51 CDR-m Okay. Very good. 



Tape 76/3 
Page U03 



Qk 20 29 56 CC Okay, Extra activities we'd like for you to 

include. We'd like the big glass "ball that you 
saw in the vicinity of the IM ~ could he picked 
up, hopefully, with the contingency sample, if 
it's convenient; if not, it should be retrieved 
as part of the LRV preparation before the EVA 
traverse. The geology people, for obvious reasons, 
are rather interested in the large black rocks you 
described on the SEVA at UO meters and 300 meters. 
And we'd like to pick those up before you leave 
sometime. And I guess a little note here, which 
sounds like motherhood to me - "collected samples 
should be taken at the crew's convenience at the 
end of the EVA." As far as the Rover is concerned, 
in our new position - - 



Ok 20 30 h9 CDR-LM Okay. 

OU ?0 30 59 CDR-LM Bob, give us a couple of minutes here for each of 

those comments, so we can come back at you. 

OU 20 31 02 CC Roger. Waiting. 

OU 20 31 09 CDR-M Okay. We were just discussing the frags around 

the IM, and we can see a number of interesting 
rocks out here. And we thought it might be better 
to wait until we get back to the IM to pick them 
up and make sTore we didn't disturb the surface 
around it, although we can pick them up fairly 
quickly in the beginning. I guess it's your 
choice. If you want to spend the time in the 
beginning or wait until we get back. 

Ok 20 31 36 CC Roger, Dave. My first flip comment there was the 

comment before you leave the Moon. The second 
comment on the "selected samples should be tak^n 
at the crew's convenience at the end of the EVA" 
was apparently intended by the geologists to mean 
selected samples of these black rocks and other 
interesting frags. Over. 

oh 20 31 57 CDR-r24 Okay. Well, do you specifically want us to pick 

up the glass ball and the black rocks before we 
start the EVA-1? 

ok 20 32 07 CC Stand by, Dave. 



Tape T6/i4 
Page 1+OU 



oh 20 32 2k CC Okay, Dave. You will put the glass tall at a 

higher priority. Apparently, because they're 
worried if the glass ball might get lost once 
the area gets mussed up a little hit, whereas 
the black rocks will probably still be there. 
Over . 

Oh 20 32 h2 CDR-LM Okay. Understand. And I guess our understanding 

of the contingency sample is that it's supposed 
to be typical of the surface around, rather than 
an exotic. 

oh 20 33 12 CC I guess that's basically true. I guess that's 

basically true, Dave; however, they would like 
this little glass ball. You could also put it 
separately in a bag before you leave with the 
Rover, or I guess they really wouldn't mind, 
if they know particularly what it is, if it 
was pajrt of the sample - contingency sample. 

Ok 20 33 3k CDR-LM Okay. We'll take care of that. 

Ok 20 33 39 CC Okay. Let me talk to you about Rover status. 

The additional distance - this 0.6 - will - and 
your new position - will not affect the electrical 
power profile. It's really a very small and almost 
trivial distance. And, secondly, the LM slope, the 
9 degrees by 9 degrees, is within the angles for 
which the deployment is specified, which is 15 
degrees, and also within the angles for which it's 
been tested. And I guess a couple of days ago 
they did test 15 degrees of pitch and 5 degrees 
of roll at Marshall, and ik degrees of pitch and 
ik degrees of roll. And, right now, we will, in 
real time, have the mockup at Marshall positioned 
corresponding to our pitchup of 9 and roll of 6 
degrees. Over. 

Ol+ 20 31+ 37 CDR-LM Okay. That's nice to hear, and it sounds like 

those fellows are planning ahead as usual . 

ok 20 3^4 kk CC Hope so. And as far as checklist changes - we 

have none. As far as TV plan updates - we have 
none. 

0I4 20 3k 57 CDR-IW Okay. Understand. 

ok 20 35 03 CC And, sometime, Dave, the medics would like a 

status report, postsleep. 



Tape 76/5 
Page k03 



Oh 20 35 17 CDR-IM Okay. Stand by. 

Ok 20 35 hk CC And, when you're ready. Falcon, we've got some 

consmnatles for you. 

OU 20 35 51 CDR-LM Okay. On the crew status, I guess we "both got 

about 5 hours sleep, based on the time we went 
to bed and the time we got up; no medication; 
and we're in good shape. And I guess you can go 
ahead with the consumables. 

OU 20 36 11 CC Roger. And how about a PDR or PHD — or whatever 

they are — read-out. 

0I4 20 36 20 CDR-LM Okay. I'll tell you, it would help us out if we 

could do that once a day. You know they're 
stowed down in the suit pocket, and we've got to 
do some digging to get them. We'll give them to 
you twice a day if you really need them, but it 
takes a little time. 

Ok 20 36 36 CC Roger, Dave. I think they're only called out for 

once a day, we agree; and somehow, I guess, trans- 
earth - or translunar, we got in the habit of 
getting them from you at the time when we didn't 
really need them, like at sleep. We got them 
from you at sleep last night; it's just that the 
checklist calls out then - calls them out for 
right now; but you're right, it is only a require- 
ment once a day, and we did get them last night. 

ok 20 37 08 CDR-m Okay. Our crew status report has them in the 

evening before bed. Do you want them then, or 
do you want them in the morning? 

ok 20 37 15 CC Say again, Dave. When does your crew status 

report have them? 

Ok 20 37 23 CDR-LM Prior to the rest periods. 

Ok 20 3T 26 CC Okay; the Flight Plan shows it in the post sleep. 

0I+ 20 37 35 CC We'd like one this morning - - 

Oil 20 37 36 CDR-LM Well, make a decision. 

Ok 20 37 37 CC Roger. We'd like one this morning before the EVA, 

and the surgeons promise they'll look at it today. 



Tape 76/6 
Page 1+06 

Ok 20 37 kf CDR-LM That's encouraging. 

ok 20 3T 50 LMP-LM Okay, Bo"b, I'm ready to copy the consijmatles .

Oh 20 39 01 IMP-LM Okay; I copy. Boh. 

Ok 20 39 33 LMP-LM Bob, I've heen looking at the descent water. It 

looks like we're off about 12 percent. Is that 
any concern down there? 

Ok 20 39 k2 CC Roger, Jim. We didn't just suddenly lose that. 

That was TELMU's understanding of how we wanted 
the consumables updated. We're having a dis- 
cussion about that right now. That was meant to 
be what your reading on board should be. I 
guess, saying that if you're reading 58 percent, 
you're in good shape. Whereas, there's a sepa- 
rate figure, which is a figure down here, which 
I guess is something like the 70 percent that I 
gave you a few minutes ago. That seems to be a 

Ok 20 kO 18 LMP-LM Okay; understand 

ok 20 1+0 19 CC That seems to be a question of how TELMU 

interprets what the consumables update should be 
We may change that around and let you know later 

ok 20 Uo 35 IMP-LM Roger. We copy. 

ok 20 k2 08 CC Okay, Hadley; this is Houston. The actual on- 

board figures, not the gage figures that you'll 
read, but the actual onboard figures for water, 
are, descent 1, 70.7 and tank 2, 68.5. Over.

once we get the suits on. 

OI+ 21 37 28 CC Falcon, Houston. Apparently, Jim's data is not 

clean, and we're not getting your data at all, 
Dave. Other that that, it looks beautiful. 

ok 21 37 kl CDR-LM Well, I guess I don't mean right now, because you 

shouldn't be getting any data right now. What I 
mean, are the signals acceptable for computation 
of PLSS data or, perhaps, if they're not, you can 
give us a suggestion so, before we get going here, 
we - we're sure that you've got good data. 

Ok 21 38 09 CC Stand by.

Oh 22 55 29 CC Endeavour, this is Houston. The first thing we'd

photopads over on the next page at 119 : 30 . 

oh 22 55 h2 CMP Okay, Karl. Go ahead. 

Oh 22 55 hh CC "Start: 119:3^:33; stop: 121:33:02." And a note 

to that is that the - the - the extend/ 
retract times on the mapping camera seem to be 
getting longer with time, and, until further 
notice, we'd like for you to record and send down 
the DELTA-T on each extend and retract. 

oh 22 56 19 CMP Okay; understand. Yes, those times do seem to be 

getting longer, and I'll record the DELTA-T and 
tell you what they are . 

oh 22 56 27 CC Roger. And, over there at 119:20, on the mass 

spectrometer boom retract, it s£^s "record the 
retract time DELTA T." Instead of "in barber 
pole," we want all of these in the future "from 
switch on to gray." That corresponds to what we 
can monitor here on the ground, and we - we need 
to - we need to calibrate - comparison of your data 
and ours. I'm sorry; that's not what we monitor, 
but this is - this is - this is - - 

Oh 22 57 02 CMP Roger. Instead you want that "switch on to gray." 

oh 22 57 05 CC Right. That compares with our test calibration 

data, that's what I sould say. And while I'm 
reading up - - 

Oh 22 57 13 CMP Okay.

ok 22 57 ^3 CC Okay. And three circuit breakers over on panel 5, 

ECS RADIATORS, CONTROLLER, AC 1 and AC 2, should

ok 23 03 20 CC Al, if you can listen while you work, I got a 

couple of short goodies for you before you go round 
the comer. First of all, the experimenters on 
the SIM bay are as happy as can be. I think on the 
gatmna ray experiment, they say on that first-rev 
data, th^ have enough to justify the whole flight; 
they're so happy with it. I have a more complete 
science report for you, which I will send up on the 
next rev. And just bringing you up to date on the 
news, the egress down on the surface will be begin- 
ning on schedule in just about 1 hour. 

OU 23 Oit 00 CMP Hey, that all sounds real good, Karl. And, as you 

can see I 'm right in the middle of a P52 here .

You'll have to read them down to us, Al. 

Ok 23 05 08 CMP Okay, Karl. I'll read them to you. P52: the 

stars were 01 and 36; the torquing angles were 
minus three halls 28; minus three balls 58; plus 
three halls 12; and they were torqued out at 
119:05, on the minute.

(laughter) that's very Interesting. There's so 
man- - so much hummocky ground around here , we ' re 
on a slope of probably about 10 degrees. And the 
left-rear foot pad is probably about 2 feet lower 
than the right-rear foot pad. And the left-front's 
a little low too. But the LM looks like it's in 
good shape. Tell the Program Manager I guess I've 
got his engine bell. (Laughter) It's a little 
rise right under the center of the LM. The rear 
leg's in a crater and - and the rim of the crater 
is right underneath the engine bell.

about a meter in diameter. And then, there's a

exposed on them, where the - the larger crater 
does not have any glass exposed. Just the smaller

point it at you at 12 o'clock, it's going to be

gives good facial resolution. Real-time data shows 
a signature of magnesium, aluminum, and silicone, 
so far. And appear to be differences cropping up 
between the mare and the highlands. The mass 
spectrcaneter PI reports good operation with many 
peaks appearing, and so far they've clearly iden- 
tified neon and argon. Gamma ray is happy, with 
improved data since separation of the LM - and 
spectral features are appearing in the data. The 
alpha particle experiment reports seeing a radon 
peak over Procellarum - and possibility of some 
other peaks over other areas of the Moon. I'll 
let you know about - more about that later. The 
photo team tells us - the photo team tells us that 
the mapping camera is working well - and the laser 
is going great. The pan camera appears to be 
getting about 80 percent of its frames in good - 
in good quality despite the V over H sensor prob- 
lem. And in general, they say, "Keep up the good 
work . It ' s looking great . " 

05 00 00 55 CMP Okay. What's the matter with the V over H on 

the - on the pan camera? You indicated yesterday, 
I guess, that there was a problem with it, but 
nobody ever explained what the problem was. 

05 00 01 IT CC Roger, Al. I'm not sure that it's well under- 

stood - it - it's - all we can say is that its 
operation is erratic; sometimes it manages to 
get the - the motion compensation right, and 
sometimes it doesn't q^uite make it. That's the 
problem we ' re working on down here trying to 
understand - - 

05 00 01 36 CMP I understand. 

05 00 01 37 CC in greater detail. 

05 00 01 hi CMP Yes, ckay. 

05 00 02 2h CC Endeavour, let's have HIGH GAIN AKTENWA, AUTO, 

please . 



Page 1*62 

05 00 02 31 CMP A going AUTO. 

05 00 02 57 CMP Karl, if you'-we got a paper and pencil there while 

I'm - -while I'm finishing up breakfast here, let 
me run down some cameras - magazines with you. 
I Just - took inventory of all the MAGs last 
night. And, thought I might just read through 
the list for you, and - 

05 00 03 18 CC Okay. Hold on a second - 

05 00 03 21 CMP - You might see what is left on the MAG now. 

05 00 03 2k CC Hold on a second, and I'll copy those. But there's 

a Flight Plan change in just a few minutes I'd 
like to get to you. The mapping camera image 
motion, which is scheduled at 120:10, we'd like 
to have at 120 :l6. 

05 00 03 h3 CMP Okay, understand. You want to slip that down to 

120:16. 

05 00 03 k9 CC That's correct. 

05 00 03 51 CMP Mapping camera image motion increase. 

05 00 03 5h CC That's affirmative, Al. And go ahead with your 

re ad- down. 

05 00 oh 02 CMP Okay. As promised to Spencer, the MAGs are as 

follows. First, the l6-millimeter stuff; MAG A's 
been used 100 percent; MAG B's been used 100 per- 
cent; C and D haven't been used; E's been used 
about h percent; F is still full; G is full; H 
has been used 25 percent; I is full; J, K, and L 
are full. Okay, on the Hasselblad, I'll call out 
the number of frames used. Okay. MAG M, Metro 
100 - 1, 5> 3 are the frames used; and Nectar is 
1+2; 0 is 39; and P and Q are 0; R is 20, and F is 
1+0. And no 35 -millimeter film has been used. 

05 00 09 15 CC That came through loud and clear, Al. 

05 00 09 21 CMP Okay. 

05 00 11 05 CMP Houston, Endeavour. 



Tape 78/39 
Page 1+63 



05 00 11 08 CC Endeavour, this is Houston. Go ahead. 

05 00 11 Ik CMP Okay. Just thought I'd orient you a little "bit 

as to where I am, Karl. At the present time, I 
am directly over Plcard, and I'm coming up on 
Proclus, here, very shortly. And from this par- 
ticular angle, looking at Proclus, the fan pattern 
out of Proclus is really magnificent. It covers 
about, oh, I'd say, ahout 2h0 degrees of arc, and 
you can see the ray pattern way, way out into 
Crisium; way out Into - into the highlands, hoth 
north, east, and south of Proclus. And, the ex- 
cluded zone is very well defined. It's very clear 
where - where the exclusion is. And I'll give you 
a little better description when we get up closer 
to it . 

05 00 12 ok CC That sounds fantastic, Al. Do you think you're 

going to solve the secret of that excluded zone? 

05 00 12 13 CMP You never know. 

05 00 12 kO CC Al, could you please confirm that your H FANS 

are OFF? 

05 00 12 50 CMP Negative, Karl. They're ON. Sorry about that. 

05 00 12 55 CC Okay. We'd like to have them OFT, Al. 

05 00 13 00 CMP Okay, they're OFF. 

05 00 13 22 CC And, they've Just been deploying the TV camera 

on the lunar surface, snd we had some of our first 
looks at Hadley Delta and St. George, and what do 
you know, it looks Just like all the pictures 
they've been drawing for us. 

05 00 13 36 CMP Hey, super. It sure looks the same from up here. 

05 00 1^1^ 01 CC Endeavour, 15 . Could we please have OPTICS ZERO? 

05 00 lU 09 CMP Roger. OPTICS ZERO. 

05 00 ik 52 cc And we've got 10 seconds for changing image motion 

on the mapping camera, Al. 



05 00 15 00 CMP 



Roger. 



Tape 78/UO 
Page U6U 

05 00 16 30 CC Al, there's no rush on it, but I'm waiting for 

your cue before I send up Flight Plan update. 

05 00 16 kO CMP Okay» Karl. I'll be ready in a minute. 

05 00 20 21 CC Endeavour, this is Houston. Rover has Just hit 

the groimd. You don't see it down below you, do 
you? 

05 00 20 3h CMP I'm not quite there yet, Karl, but I'll look when 

I go over. 

05 00 20 37 CC Roger. 

05 00 21 50 CC Endeavour, we'd like to have PAN CAMERA POWER, 

OFF. 

05 00 22 02 CMP Okay, all turned off now. 

05 00 22 05 CC Thank you. 

05 00 28 26 CC Endeavoiir, the first part of that Flight Plan 

update is to delete the gamma - gamma ray boom 
deploy at 120:33- We want to be s\ire to get that 
one. Delete "gemma ray boom, deploy." 

05 00 28 k3 CMP Okay, Karl. I'll delete it, 

05 00 31 01 CMP Okay, Karl. Looks like I'm set for business for 

the day now. And, go ahead with your Flight Plan 
update . 

05 00 31 09 CC Okay, Al. First of all, on the gamma ray boom, 

the reason for that, is the fact that we're getting 
a little gain change every time that we deploy and 
retract it. It's not serious, but we'd like to 
sort of leave it as it is until we study the prob- 
lem a little longer. You've already deleted the 
extension at 120:33. We also, then, will delete 
the retraction at 121:27. 

05 00 31 hS CMP Okay. 121:27. Roger. 

05 00 31 51 CC And while you're on that page, the mapping camera 

photo - 

05 00 31 55 CMP 



Tape 'jQ/hl 
Page 1+65 



05 00 31 56 CC Roger. And while you're on that page the mapping 

camera photo pad is as follows. Start, 121'.39'3h', 
122:32:U3. WoTild you like to read that back? 

05 00 32 ih CMP Okay. 121:39:3^, and T-stop is 122:32:1+3. 

05 00 32 20 CC That's correct. And Just on the same page again. 

The attitude - the attitude there at 121:37, in- 
stead of reading a roll angle of "000," should he 
"IU2." That's for the P20 option 5. 

05 00 32 1*5 CMP Okay, understand. Roll angle of 1U2. 

05 00 32 1*9 CC That's correct. The next correction is all the 

way vcp at 125 hours and 1*1+ minutes. 

05 00 33 07 CMP Okay, go ahead. 

05 00 33 08 CC And, this is one of those general things. On re- 

porting the DELTA-P, it should be from switch ON 
to talkback gray. 

05 00 33 23 CMP Okay. 

05 00 33 25 CC And, we have exactly the same thing at 129 hours 

and 20 minutes. 

05 00 33 1+2 CMP What was that again? What time was that? 

05 00 33 1+5 CC At 129:20, the same thing, the switch - the 

DELTA-P that you read back to us is switch ON to 
talkback gray. And really, I suppose, we should 
make this a generality - that we don't have to 
put it in the Flight Plan every time. 

05 00 31+ Ol* CMP Roger. I'd agree to that. 

05 00 3I* 06 CC Incidentally, I have a question in that connection 

says verify that times previous to II8 hours were 
from switch ON, beginning time. Do you recollect 
that? 

05 00 3I+ 26 CMP Karl, the way we time it on board here, is you 

have to hit the switch, and then look at the 
mission timer. Now, the - the gamma ray is taking 
about 6 seconds to go from switch ON to barber 
pole, the mass spec was going on immediately to 



Tape T8/i;2 
Page k66 



bar"ber pole, so it didn't make any difference in 
the case of the mass spec. And in the gamma ray, 
the most it could "be off is 6 seconds. 

05 00 3^ 5^ CC Right. And, - I guess on the gamma ray when you 

reported the time - do you recall which it was that 
you were giving us , switch OH or talkhack barter 
pole? 

05 00 35 06 CMP Talkhack barber pole. 

05 00 35 08 CC Okay, fine. That's the way the instructions were, 

originaJ.ly . 

05 00 35 18 CC We have a comm change. It's simply an error in 

o\xc Flight Plan at 126:10. 

05 00 35.35 CC And, at 128 - 

05 00 35 36 CMP Okay, go ahead. 

05 00 35 37 CC - at 128:10, the first step in that configuration 

is "VHF AM A, SIMPLEX." The second step is to 
change "VHF AM B," delete "DUPLEX," and make that 
"OFF." 

05 00 36 06 CMP Okay. Understand you want SIMPLEX A in, B - and 

B, OFF. 

05 00 36 10 CC That's correct, and at ikg hours and 37 minutes, 

we do the same thing. 

Okay, gotcha. 

And at 11+9:37, we also want to add "mode VOX." 
Okay, Understand, "node VOX," 

Roger. And, I think the last item to come up is 
again the comm change at I69 hours and 20 minutes - 
that we put "A, SIMPLEX" and "B, OFF." 

Okay, Roger. Got those. 

Okay. That takes care of our current Flight Plan 
updates .

05 01 U6 l6 CC Roger. Our TV pan suggests, you can go straight 

for St. George Crater, and you'll find Elbow okay. 
And we're suggesting you omit Checkpoint 1 - 
Rhysling Crater should be a good landmark along 
the way, and head 208. Over. 

05 01 U6 36 CDR-EVA Okay. 208, Joe.

Jim? 

05 01 hj 21 LMP-EVA Probably is - this large depression off to our left?

Just like ik . Up and down we go. Oh, and this 
must be earthlight, hiih? Could that be? Boy, 
look at that; we're going to have to do some fancy 
maneuvering here. 

05 01 k'J 55 LMP-EVA There's an elongate depression here before you get 

to Rhysling. I don't think we're to Rhysling yet - 
Rhysling ought to be about l.U. We've only gone -

05 01 i+8 08 CC We think you're short of Rhysling now. 

05 01 1+8 13 LMP-EVA Do you think that's probably Rhysling out about 

11:00 o'clock to us, Dave? 

05 01 hQ 17 CDR-EVA Okay. 

05 01 hQ 18 LMP-EVA Out about - maybe 1 kilometer. 

05 01 hQ 21 CDR-EVA Yes. Okay, Joe, the Rover handles quite well. We're 

moving at , I guess, an average of about 8 kilometers 
an hour. It's got very low damping compared to the 
one-g Rover, but the stability is about the same. 
It negotiates small craters quite well, although 
there's a lot of roll. It feels like we need the 
seat belts, doesn't it, Jim? 



05 01 hQ h.9 LMP-EVA 



Yes, really do.

the rear steering. It does - does quite well. 
There doesn't seem to be too much slip. I can 
maneuver pretty well with the thing. If I need 
to make a turn sharply, why, it responds quite 
well. There's - there's no accumulation of dirt 
in the wire wheels .

05 01 52 00 CDR-EVA The zero-phase riding is pretty tough, Joe. We're 

going to have to make sure we keep at an angle. 
Once I look into zero-phase, it all looks flat. 
There's a nice little round 1-meter crater with 
very angular frags all over the bottom and the 
rims, and glass in the very center. About a meter 
across . 

05 01 52 27 CC Roger, Dave. And, Jim, as you come up on the rille, 

you may want to turn your l6-millimeter camera on. 

05 01 52 37 LMP-EVA Yes , when we get to the rille, we will, Joe. Can't 

see the rille at all from here. Still looking for 
Rhysling.

05 01 53 28 LMP-EVA Yes. We have a large subdued one on our right about 

60 meters wide with several small ones in the

05 01 58 15 CDR-EVA Yes, it - subtle though - subdued. 
05 01 58 17 LMP-EVA ... turn on the camera. 

05 01 58 18 CDR-EVA Hey, look there's a big block on the edge of the 

rille there that must be 10 meters. There are 
lots of outcrops. But, on the far side, I don't 
see anything that would suggest really layering. 
There's a lot of debris, big angular blocks all 
the way down, but nothing that you'd really call - 
exact layers . 

05 01 58 hi CC Roger. We copy. 

05 01 58 k3 CDR-EVA Let me get us back up on it - back up on the ridge 

it's smoother. 

05 01 58 U7 LMP-EVA Yes, I think that heading was - we were on a head- 
ing of a little too far west. We're getting back 
up on the higher part of the rille rim. At this 
point, I'd estimate the slope is probably - what? 
About 3 degrees? 

05 01 59 03 CDR-EVA Yes, there's a definite branch or rim that runs 

along the rille, maybe 70 - 80 meters from this - 
the inflection point that drops down into the 
rille, don't you think, Jim? 

05 01 59 15 LMP-EVA Yes. And, we might as well - we're heading right 

toward - we'll head toward the east side of - of 
Elbow. 

05 01 59 2k CDR-EVA Yes, we're in good shape. We can see Elbow, and 

we can see the front all the way down to the Spur. 
And, there's not a big block on it. 

05 01 59 37 CC Keep talking, keep talking. Beautiful description 

05 01 59 *+0 CDR-EVA Hang on.

05 02 00 10 mP-SVA Looking up at the - at the ft-ont now, Joe, I sxire 

see the linear patterns that Dave commented on 
before. With the dip and everything. 

05 02 00 18 CDR-EVA Whew, whoopee! 

05 02 00 19 LMP-EVA Boy, that was a - good stroke. 

05 02 00 21 CDR-EVA It's a good stroke, all right. 

05 02 00 2k LMP-EVA And, I sure get the impression that - Almost looks 

like a slump feature, but we'll take some good 
pictures of that , because you see the same lineal - 
linear-type pattern in the - the east side of the 
rille. And note the linear pattern there is par- 
allel. Almost like layering in the rille. And, 
then as you look upslope - up the front, that layer- 
ing takes thiat - that dip to the northeast that 
Dave had mentioned earlier. 

05 02 01 02 CC Roger, Jim. And can - can you actually see the 

east side of the rille, towards the south there? 

05 02 01 09 LMP-EVA Oh, yes. I can see, looking directly south - I can 

see that - that exposure - the exposure that faces 
northwest. I can look down and I can see - I think 
I can see Hadley C down there. 

05 02 01 23 CC Remarkable. 

05 02 01 2k LMP-EVA Yes, I think I can see the south rim of Hadley C. 

05 02 01 38 LMP-EVA Okay, let's see - Well, we can see Elbow. But 

anyway, when we get there - -

05 02 01 i+T CDR-EVA Oh, my. 

05 02 01 50 LMP-EVA It shoiild be 2.7, so we got another .7 to go. 

05 02 01 55 CDR-EVA Okay, we're doing all right. 

05 02 02 00 LMP-EVA Speed's heen generally about 10 clicks. 

05 02 02 02 CDR-EVA Yes - but it takes attention paying. 

05 02 02 11 LMP-EVA Yes. And again looking at the - looking to the 

south along that - the edge of the rille that faces 
to the northwest, I can see several large blocks 
that have rolled downslope. Very large blocks 
that are about three-quEirters of the way down 
the - slope - into the rille. That's just at the 
base of St. George. 

05 02 02 32 CC Roger, Jim. Copy. 

05 02 02 kO LMP-EVA And - we're heading - heading about 165 - right 

now. Tried to stay on the fairly level and smooth 
part of the Rille rim. But looking over to the - 
the edge of the rille at this point , I see a - a 
large concentration of large boulders - large rocks, 
And I'd estimate the size - They're angular, and - 
they're all of the same color and texture as - as 
far as I can tell from here. See that ...? Well, 
you'd better watch the road, Dave. 

05 02 03 22 CDR-EVA Yes. No , I see what you're seeing there, but - 

you - you keep talking; let me drive. 

05 02 03 26 LMP-EVA It's the first good concentration of large rocks 

that I've seen. Very similar to the large rocks 
that - that ih saw up at the top of Cone. 

05 02 03 1+2 CC Roger, Jim, we copy. And your range should be 

coming up on 3-1, at Station 1. 

05 02 03 51 CDR-EVA Okay, relative - Right now, Joe, our bearing is 

18 and range is 2.3. 

05 02 03 57 CC Roger. 



05 02 OI+ 08 LMP-EVA Okay; now, Joe, I can - see the - the bottom of 

the valley - Head Valley that leads down toward 



Tape 79/26 
Page I+9U 



Hadley C. I can see the - the hottom of the rille - 
it's very smooth. I see two very large boulders 
that are right on the surface - there, on the top 
of the very smooth portion, of the bottom of the 
rille. -And the one to the - the southeast, I cai: 
see the track, of where it's rolled downslope. 

05 02 ok 53 CC Roger, Jim. Copy. And is the bottom V-shaped or 

fairly flat? 

05 02 OI+ 59 LMP-EVA I'd say it's flat. I'd est - Well, it's hard to 

estimate. I'd - I'd estimate maybe - oh, 200 meters 
wide of the flat - flat area in the bottom. Oh , 
and I can see what we thought was Bridge Crater. 
And - it definitely would not have been a place to 
cross Hadley Rille. It's just a depression in the 
west wall of the rille. And I - Boy, at this van- 
tage point, there's sure a lot more blocks exposed 
on the - on the far side of the rille. I'm con- 
trasting now the rille to the southeast - - 

05 02 05 1+7 CDR-EVA Cop, hang on, Jim. 

05 02 05 hQ IMP-EVA Okay - and the rille to the - side of the rille to 

the northwest. 

05 02 05 52 CC Roger, Jim. Copy all that, loud and clear. And 

Dave, is the front wheels - are the front wheels 
wandering off of straight ahead as you drive along 
there? 



05 02 06 oh CDR-EVA No, they're okay, Joe, it's just - There are a 

lot of craters and it's just sporty driving; I've 
just got to keep my eye on the road every second. 

05 02 06 12 CC Roger. We understand that - - 

05 02 06 13 LMP-EVA By golly, it's a real test for the Rover. 

05 02 06 ik CC - - just want to get some info - engineering in- 

formation here. Apparently, your front wheels 
are tracking straight ahead, is that correct? 

05 02 06 23 CDR-EVA That's correct. And, of course, when we turn, 

they dig in, and it makes the rear end break out. 
But it ' s okay ; we can handle it . 



Tape T9/2T 
Page U95 



05 02 06 31 CC Knew you could. 

05 02 06 33 CDR-EVA I might add to Jim's comment, that the near - the 

near side of the rille wall is smooth without any 
outcrops, there by St. George, and the far side 
has got all sorts of debris. It almost looks like 
we could drive down in on this side, doesn't it? 

05 02 06 U8 CG Stand by on that, Dave. 

05 02 06 k9 LMP-EVA I'm sure we could drive down; I don't think we 

could drive back out. 

05 02 07 00 LMP-EVA Oh, now - I can turn around and look to the north- 
west - where the rille trends to the north. Now, 
let me concentrate on Elbow for the moment . 

05 02 07 11 CDR-EVA Yes, let's get to Elbow. 

05 02 07 20 CDR-EVA (Laughter) Hang on. 

05 02 07 26 LMP-EVA Okay, our range - the range estimate must have been 

off for Elbow. Our map says 2.7, Joe said 3.2, I 
guess. You confirm that, Joe? 

05 02 07 36 CC Our estimate, Jim, was 3.1 from your landing site. 

05 02 07 U3 LMP-EVA I see, that's right. 

05 02 07 kh CDR-EVA That's the difference, 

05 02 07 U5 LMP-EVA Yes. 

05 02 07 51 CDR-EVA (Laughter) Well, this is really a sporty driving 

course. Man, oh, man, what a Grand Prix this is! 

05 02 08 Oh CDR-EVA There's old Elbow. 

05 02 08 07 LMP-EVA Is it? 

05 02 08 08 CDR-EVA There's a real fresh one down here. 
05 02 08 10 LMP-EVA No, Elbow's larger than that. 

05 02 08 12 CDR-EVA Yes, but there's - Hey, there's a nice fresh one 

then.

05 02 21 53 CDR-EVA Okay, Joe. I've got a - another subangular frag- 
ment here. Rough surface texture. And, knock a 
little dust off of it, and it looks like a very 
fine-grained, gray - rather solid frag. I don't 
see any significant pits or any significant-size 
crystals in there. It might Just be "because the

Okay, here's another one that's got - Oh, on - on 
the imderneath side of that - I hope I don't lose 
these tongs - On the underneath side of this frag, 
Joe, I can see some soil that is caked on the bot- 
tom, about 1 millimeter thick, and maybe down in 
the place from which I got it, we could sample. 
Why don't we get it - I'll take a picture and you 
can scoop that. And there's another one that has

a lot of angular blocks on the rim of it .

over there at about - 11 o'clock. 

05 02 30 58 CDR-EVA Okay, it's about 20 - 25 meters across, and it 

looked like it excavated the bedrock; it had a 
very blocky ejecta blanket and blocky rims, and 
the ejecta blanket was about halfway out. 'eiocks 
on the order of about a foot and a half - at the 
largest. And some angialar, some quadangular.

05 02 02 25 CMP Roger, Houston. Stand by for 1 minute. 

05 02 05 55 CC Endeavour, this is Houston. The information we 

have on your attitude indicates that you're a 
little bit off for those forward obliques. And, 
we'd like to see your NOUN T&, if possible. 

05 02 06 09 CMP Okay. They were as per Flight Plan. In fact, 

Karl, I wanted to mention that to you. When I 
loaded NOUN 78 with plus 126.30 and plus 0^5. 77, 
the computer came up with an angle, or an attitude

has crossed quite a bit of territory, now. And, 
they're on the edge of the rille, having a good 
look into it.

05 02 10 15 MCC Hey, morning, Al. Hey, first of all, Isi said to 

tell you that your - - 

05 02 10 20 CMP Good morning, Vance. Hey, I'm - I'm looking at 

our favorite crater right now. 

05 02 10 2h MCC Is that right? It couldn't be King Crater? 

05 02 10 29 CMP Yes, sir. I'm right over Proclus , now. Proclus.

05 02 10 1+3 CMP Very good, how's Isi? 

05 02 10 kh MCC He's good. He says to tell you that you make a 

dandy spectrographer - for X-rays, that is. He's 
getting a lot of data in. I guess, actually, a 
little more activity than they expected, and they 
seemed real pleased about that . 

05 02 11 0I+ CMP That's good. That ought to keep Pete and Jack busy. 

05 02 11 07 MCC Getting into the pan camera. I don't know how much 

has been explained to you. It's - it's taking 
pictiires - about 80 percent of them are good. And, 
the problems in the V over H sensor, which I'll try 
to explain here, briefly. The V over H sensor is 
drifting, which means that, occasionally, it drifts 
down to the - to the place where it thinks that - 
you're out of the h5- to 80-mile limit. Whenever 
it does that, why, it - the camera is commanded 
back to a nominal 60 setting. As it tiorns out, it 
drifts enough that it - it's out of this band most 
of the time. And that's actually good because 
you're at 60 miles, so it's - it's going back to 
the 60-mile limit , probably to give you 8O percent 
of the time good pictures. The fault - We're not 
quite sure where it is - ; people are working on 
that. It's probably either in the sensor or up- 
stream just a little ways in the electronics. 



05 02 12 26 CMP

report . The data seems to be coming in on aJ.1 the 
experiments, ajid it's looking pretty good. 

05 02 12 kh CMP Yes, I noticed just - some - some problems vith 

getting the booms in and out, Vance; but, outside 
of that, everything seems to be okay. The mapping 
camera is taking about h and a half minutes to 
retract now. And, I had a little trouble getting 
the MASS SPEC in the last time, and I ran it out 
and in a couple of times, before it finally came 
all the way in. 

05 02 13 Oh MCC Roger. AUTO on HIGH GAIK. 

05 02 13 11 CMP Roger. AUTO. 

05 02 13 18 MCC And, Al. The next time you extend and retract the 

boom, they'd like a - a hack on it - and on the 
mapping camera, too, because, - Stand by. I'm 
sorry, they'd like hack - a time hack when you 
start extending the map - mapping camera and when 
it gets out, because they're looking at the cur- 
rent signatures and that sort of thing on it. 

05 02 13 50 CMP Okay. They want to help me keep time, do they? 

05 02 Ik Ok MCC We're Just looking at the real-time electrical, 

both signatures, when this - this thing is working - 
extending and retracting, Al. And, we'd like to 
have a hack so we will know when you - when we can 
start looking. 

05 02 Ik 21 CMP Okay, I understand, them then. You - you're watch- 

ing the - the voltage levels or power levels in the 
motor that drives the extend - release. 

05 02 Ik 31 MCC That's affirmative.

05 02 IT 58 CC Endeavour, go ahead. 



05 02 18 Oh CMP Okay, Karl. This may be the wrong attitude for 

what we WEUit , but it's such good viewing attitude 
that - let me make a couple observations while 
we ' re here . 

05 02 18 12 CC Great. We're listening. 

05 02 18 IT CMP Okay. I'm right directly over Littrow at the 

present time. And, I can see all the way around - 
to the Apennine Front - encompassing all of 
Serenitatis between here and there - except to 
the north over by Posidonius. So, I got a very 
good view of Sulpicius Callus - and that sort of 
extends off my 10 - 11, to 12 o'clock position. 
And the observation I wanted to make, in particiilar, 
was - the - the distinct way that the - that the 
rilles do follow the - the old mare basin. And, 
the fact that the second color band that we dis- 
cussed in Littrow - seems to be continuous right 
on across the - the basin into Tranquillitatis and 
on around - almost a shelf - a continental shelf - 
appearance - on into the Sulpicius Callus. And, 
that seems to be that second color band that we 
noticed in Littrow. There is a darker color - 
coloring - in the uplands in Littrow and closer to 
the - to the front or closer to the basin of - of 
Scarp. But the second band seems to go all the 
way around Sulpicius Callus. And, then - as you 
follow Siilpicius Callus on around a little bit 
more to the west, that color banding is still there. 
I can see a distinct boundary between it and the - 
and the Serenitatis Basin itself - inner basin - 
but it turned into little more brownish color from 
the gray color that we saw before. 

05 02 20 08 CC Roger, Al. You're coming through loud and clear. 

05 02 22 2T CMP Houston, Endeavour. Karl, I've got Hadley Rille 

in sight now in Front, Have a very commanding 
view of the whole countryside. 



05 02 22 39 CC 



Beautiful. Any chance of spotting Rover tracks 
down there , do you think? 



Tape T9/^5 
Page 513 



05 02 22 52 CMP Well, I got the binocular out and I'll let you 

know. 

05 02 26 37 CC Al, while you're getting a beautiful view from 

up above, we Just got a - some beautiful pan shots 
of Hadley's Rille and saw all sorts of blocks and 
bedrock sticking out of the rim of it. 

05 02 26 53 CMP Roger, Karl. I can vouch for the rocks and the 

blocks in the bedrock in the rille. I can see it 
from here with a binocular. I didn't have much 
luck picking up the Rover. I think I got a - I 
think I got a look at the - at the LM again 
through the binoculsir - but I wasn't real sure. 

05 02 27 10 CC Very good. 

05 02 27 25 CC You must be Just about over the area south of 

Archimedes , there , with all those sinuous and - 
and linear rilles . That's pretty choppy country, 
isn't it? 

05 02 27 39 CMP Yes, that's affirmative. And that's right where 

I'm at now. Just south of Archimedes and this - 
hummocky, hilly terrain south of Archimedes is, 
in fact, guite full of - of rilles, although 
they're very subdued rilles. They - they don't 
have much definition to them, even in this low 
Sun angle. But, they're combinations of linear 
rilles, which seem to run northwest, southeast and 
sinuous rilles, which have no partic-ular direction. 
And then, I noticed a couple of rilles have - in 
fact - I'm looking at one right now. In this, we 
see a small crater pair Just to the left of 
Archimedes and a real light feattire roanning to the 
east out of it. And that rille feature has a - a 
series - a whole succession of - of craters run - 
running right down the rille . 

05 02 28 38 CC Right down the rille. Any - any sort of blankets 

around these craters? Does it look like volcanic 
chain there coming out of the rille? 

05 02 28 5^ CMP Well, it certainly looks like a volcanic chain. 

Let me check and see if I can see any rims to them. 



Tape 79/1^6 
Page 51^ 



05 02 29 10 CMP No, I don't see any rim - rim deposits associated 

vith them. In fact, the - the craters that I'm 
looking at are irregular in shape, elongate in 
direction of the rille , and they look distinctly 
like collapsed featxures in a lava tube. 

05 02 29 30 CC Very interesting. 

□5 02 29 39 CMP They didn't seem to have any particular shape, 

except that they were elongate in the direction 
of the rille and I didn't notice any particular 
any - any buildup aromd the - the mountain. In 
fact, in this particular Sun angle, which is 
rather low, I didn't really see much elevation

There is one boulder I Very angular, very 


rough 



surface texture. Looks like it's partially - Well, 
it's got glass on one side of it with lots of bub- 
bles, and they're about a centimeter across. And 
one corner of it has got all this glass covering 
on it; seems like there's a linear fracture through 
one side . It almost looks like that might be a 
contact; it is, within the rock. It looks like we 
have a - maybe a breccia on top of a - a crystal- 
line rock. It's sort of covered with glass; I 
can't really tell, but I can see a - a definite 
linear feature through one side of it which is 
about a fifth, and the glass covers both sides of 
what I guess I'm calling a contact. And there's 
also, parallel to that contact, one surface, which 
is quite flat, only for about 8 inches or so. 
Looks like it's been chipped off. The boulder it- 
self is on the order of about a meter across and may- 
be a - Gee, it looks like a half meter thick or so. 
It's got a fillet up one side, and the Earth side is 
in a shadow. I can't really tell whether - It doesn't 
look like it's filled. It's got a fillet on the down- 
slope side, and - the upslope side is - is open and 
free . As a matter of fact , it looks like it ' s . almost 
excavated beneath it.

to be quite a bit of debris up there along where 
the Twins are, up on the rim.

05 03 05 02 LMP-EVA Yes. Okay; I'm going to go over and configure for 

it. 

05 03 05 06 CDR-EVA Okay. Hey, Joe, we've got a crater that looks 

sort of fresh up here, oh, a hundred meters or so, 
looks like, with a fairly fresh rim. Woiild you 
like a double core on the rim of that, or would 
you like us just to pull it right here? 

05 03 05 22 CC Stand by. 

05 03 05 28 CDR-EVA There's a change in albedo on the rim; it's much 

lighter. 

05 03 05 31 CC Roger, Dave. Drive the core right down through 

the rim. 

05 03 05 37 CDR-EVA I thought you might say that. Okay. Take some 

of this stuff back, and we'll have to walk up 
there. But that won't take too long. 

05 03 05 1+7 CC You were just checking up on us.

05 03 05 59 CDR-EVA Okay, Jim. You got everything you need? And I'll 

Just come up there with you. 

05 03 06 02 LMP-EVA Yes. Come on up here, and I'll get the cores up. 

05 03 06 03 CDR-EVA Okay. Here we go. Head up to the crater. Think 

we can get there without any trouhle? 

05 03 06 09 LMP-EVA This one right here, you mean? 

05 03 06 11 CDR-EVA No, I was thinking of Bright One. The - - 

05 03 06 Ik LMP-EVA That'll probably take a good 5 minutes to get up 

there . 

05 03 06 16 CDR-EVA Yes, you're right. I guess - Well, we'd be pushing 

it. 

05 03 06 22 LMP-EVA Yes. 

05 03 06 23 CDR-EVA Joe, I guess we'd take 5 minutes to get up there. 

What do you think? 

05 03 06 27 CC Negative. Drive the core where else you think 

might be convenient. 

05 03 06 3h CDR-EVA Oh. we've got a good place here. We've got a 

fairly deep crater; it must be about 10 meters 
across, and a meter and a half or so deep, and 
we'll pick the rim of that - There's a fresh im- 
pact crater in - in the rim anyway, which looks 
like it pulled out some - - 

05 03 06 5^+ LMP-EVA Let me get it. 

05 03 06 55 CDR-EVA Is that a good enough place for you, Jim, right 

here? 

05 03 06 56 LMP-EVA Sure is, Dave. 
05 03 06 58 CDR-EVA Okay. 

05 03 06 59 LMP-EVA I wouldn't want to go up much farther on this slope. 

It's too hard to get up. 

05 03 07 01 CDR-EVA It sure is, isn't it? 

05 03 07 02 LMP-EVA You're right ... kicking too much.

05 03 09 15 CC And, Dave and Jim, as you're getting a double core 

for us there, ve'll be wanting to leave the sta-

the big camera photograph following this . I think 
we're in good shape on everything else. 

05 03 09 32 CDR-EVA Okay, Joe. Is that as far as you can push it, Jim? 

05 03 09 35 LMP-EVA That's as far as I can push it. I got the picture;

and there's a nice, big, very interesting outcrop 
over there, which looks like vertical jointing in 
a big block, with a horizontal layer on the top; 
the block must be, oh, 2 percent of the rille 
height and it must be about the - oh, twice that 
across, with the layer maybe one-quarter of the 
height of the block, and I got a 500 of that. I'll 
also take you a 500 vertical in the same area. 

Roger, Dave. And we're interested in your climbing 
aboard now and start back towards the LM. We're

lot more definition than straight down -Sun. I 
don ' t think we ' 11 have any trouble driving up-Sun , 
because the craters seem to show up pretty well. 
Have you noticed here on Elhow, it seems like there' 
a very subtle bench on the southern side? 

05 03 31 03 LMP-EVA Yes , I kind of got the idea there were several. 

subtle benches in the downslope - a - particularly 
on that - on the eastern wall. 

05 03 31 13 CDR-EVA Yes. 

05 03 31 1*+ LMP-EVA On the wall.

Page 5^8 

05 03 31 53 CDR-EVA I'm going to do the NAV system here, once we get 

squared away and get out of the hole. Incidentally j 
Joe, I don't think we saw any indication of flows 
or a slide or anything coining off of Hadley Delta 
there. I - I didn't see anything that looked like 
a change in granularity or - any subtle - scarps 
of any sort. Did you notice any, Jim? 

05 03 32 19 IMP-EVA No. ... - - 

05 03 32 20 CC Roger. Dave, that's exactly the picture we "built 

from your verbal description there and that's the 
reason - one of the reasons we're going to omit 
station 3- We think that there probably is not 
at least a sharp debris flow down the side. 

05 03 32 37 CDR-EVA Yes, okay. I think that's a good decision. I 

don't think we're going to find much more over 
there than we've already found. 

05 03 32 k2 LMP-EVA You know, looking out to the east now, Dave, I 

see some little very subtle ridges. I think 
they're ridges rather than craters. And it's 
probably - Well, it's out toward the secondary 
crater cluster. 

05 03 32 56 CDR-EVA Yes. 

05 03 32 57 GC ... cluster, Jim, sounds reasonable. 

05 03 33 Oi+ CDR-EVA Okay, bearing 11 for a 3.3 kilometers. We'll see 

you on that - -

05 03 33 20 LMP-EVA Yes. ■ 

05 03 33 21 CDR-EVA Gosh, I sure wish we had more time to sample. 

05 03 33 25 LMP-EVA I think I see the - I see something reflecting 

over there . I think that ' s the LM .

05 03 33 36 LMP-EVA Yes, we see it, Joe. 

05 03 33 39 CDR-EVA Sure do. And we're heading right straight for it 

on a bearing of 11 degrees (laughter), except for 
the wanders through the craters . 

05 03 33 52 CDR-EVA Boy, I'll tell you, Joe, this is a super way to 

travel; nice and cool - uphill without any strain. 
This is great , 

05 03 3k 00 CC Yes, sir. 

05 03 3h 10 CDR-EVA And it's easy to drive; no problem at all. Just 

have to be careful because of the locked front 
wheels , but other than that , very responsive . I 
can put the throttle right up to the stop or at 
some intermediate position, and take my hand off - 
and rest hand; if I want to go left or right, 
I just put a little pressure until I get the angle 
I want and then let it off and we recenter on the 
steering. It's - really neat, even with the locked 
front wheels. 

05 03 34 hk CC Sounds mighty smooth, Dave, And we're still work- 

ing on your front wheel problem. We may have them 
back before you know it. 

05 03 3^+ 53 CDR-EVA Okay; I'd like to try it that way, too. 

05 03 3I+ 56 LMP-EVA Looking over to the east, Dave, I see a very 

large crater, and it could very well be - - 

05 03 35 01 CDR-EVA Could it be Dune? 

05 03 35 03 IMP -EVA No, it's probably too close to be Dune. 

05 03 35 05 CDR-EVA Yes. 

05 03 35 06 LMP-EVA Maybe it's Fifty- four.

No. 



05 03 35 28 CDR-EVA I'll bet you - I wouldn't be surprised if it didn't 

come from that crater. Too bad we can't stop. 
There's a rock that was sort of rounded, but 
had a rough surface texture to it, about a half 
a meter in size, and it was about 10 meters down- 
stream from a nice fresh crater that had a lot of 
angular debris in the bottom and the walls . 

05 03 35 5h CDR-EVA There are a lot of little craters around here - 

little being less than a meter - which are very 
rough, have a lot of debris - right up to the rim 
and over the top side of the rim, and no eject a 
blanket to speak of, but the whole inside of the 
wall - take a half a meter crater and it's filled 
with angular, gray, fragmental debris on the order 
of inch size - or less, very uniformly distributed, 
fairly well sorted. Like - maybe they came - 
maybe the debris is from one of our Aristillus or 
Autolycus friends. And there's a lot of it, so 
I think we'll have a chance to get it later on. 

05 03 36 53 CDR-EVA They're rather shallow craters, too. Let's say 

that they're only about - oh - 1 to 6 . Hang on, 
Jim. 

05 03 37 07 LMP-EVA Yes, look at - There's a large flat rock over at

Okay. 

We're not in bad shape at all. It's looking real 
fine . 

Okay. 

And we may be in better shape when you arrive 
there . 

Okay; we'll see how we do. Oops! Hang on, buddy. 
Yes. 

Every once in a while, when one of the steering 
wheels comes off the ground - due to bumping in a 
crater, and we get a side force, why, the rear end 
will break out, because we've lost our directional 
control. 

Dave, could you comment on the - the horizontal 
bedding in - in Hadley - looking out the foot of 
Hadley, that spur that comes out - - 

No, no.

that's - maybe only 10, 15 percent of that partic-

nitely linear pattern that looks like it dips 
30 degrees to the west. How come we stopped? 

05 03 39 32 CDR-EVA I got to put my seatbelt on.

Looks like about 10 meters across, and it's got 
up to 6-inch frags aro;md the rim - maybe 15, 
20 percent of the rims has frags in it but 
nothing - no significant ejecta blajiket, which I 
think is typical of all these around here. That 
one looks like it's maybe a meter and a half deep. 
Yea, we can't get in it, and I bet it has glass 
in it, too.

05 03 50 Ul LMP-EVA Yes. Occasionally as we drop dovn in these - You 

know, I kind of get the impression, Dave, we're 
go - it's almost like - Well, they're depressions 
and then there's the rises, and they're generally 
perpendicular to our direction of travel. 

05 03 50 57 CDR-EVA Yes? Now that you mention it, you're right. Sure 

does seem that way, doesn't it? We're Just going 
up and down the - Ha - Now watch your frequency. 
Whoop i watch out; hang on. On that one. Hang 
on the next one. Oh, ho. 

05 03 51 16 IMP-EVA Like Just small valleys that are trending upslope, 

Joe. And - we go down low enough so that we can't 
see the LM anymore. Won't see him until we get on 
top of the next rise. They're very gentle valleys. 
And they're about - wotald you say - 60 , 70 meters 
across? 

05 03 51 hi CDR-EVA Yes. 

05 03 51 5^ IMP-EVA And, you know, the terrain, looking from the east 

here - the - is Just a general rise to the east. 
It looks like, oh, 2 - 2 or 3 percent. Notice 
that, Dave? 

05 03 52 06 CDR-EVA Yes, up to 

05 03 52 07 LMP-EVA Right to the - - 

05 03 52 08 CDR-EVA . . . 

05 03 52 09 IMP-EVA - - the hase of the Apennines. 

05 03 52 10 CDR-EVA Yes. And it's - - 

05 03 52 11 LMP-EVA Right up to - the Swan Range there. 

05 03 52 Ik CDR-EVA Yes. 

05 03 52 18 IMP-EVA Now when we go out on EVA-2 , why, it'll be uphill 

going out, and prohably downhill all the way back. 



05 03 52 25 CDR-EVA 



That's nice. Whoop! There's a shocker. Boy, 
what a great suspension system this thing has 
( laughter ) . 



Tape 8O/U5 
Page 559 



05 03 52 33 IMP-EVA It'll be a tremendous view back to the LM when we 

get out to the last station on EVA-2. 

05 03 52 56 LMP-EVA And rather than this being the plains, as such, I 

get the idea it's the - kind of a base of a very- 
gentle talus slope . 

05 03 53 08 CDR-EVA Yes, that's - that's right. We're not on a flat 

plain; it looks like it slopes down from the - the 
Swan Range over there into the rille , and then 
when you get to the rille rim, there's another 
slight break-down to a sharp break. The slight 
break goes, maybe, 50, 60 meters, and then you drop 
off steep into the rille. It doesn't look like 
we're in a - a basin so much, although if I look 
to the left, Jim, I can see a rise - up to the - 
the rille. 

05 03 53 36 LMP-EVA Well, there might be a rise, you know, there at 

the - at the rille. 

05 03 53 39 CDR-EVA Yes. 

05 03 53 hi IMP-EVA Yes. Rise at the rille. But you're definitely- 
right, we're traveling on a slope to the left 
right now. 

05 03 53 U8 CDR-EVA And, boy, you really get that impression if you, 

you know, look east, look up-Sun. 

05 03 53 52 LMP-EVA Yes, you sure do. 

05 03 53 59 CDR-EVA I can't believe we came over those mountains. 

05 03 5k 05 LMP-EVA We did. 

05 03 5^ 07 CDR-EVA It's just a beautiful little valley. 

05 03 5^ 11 LMP-EVA Yes, those are pretty big mountains to fly over, 

aren't they? Here's a nice, subtle crater with a - 
with a - about 70 meters across, with a sharp, 
15-meter one on the rim, which scattered debris 
out. But no big ejecta blanket, no rays. 



05 03 5^ 33 CDR-EVA 



We can't see the LM now. And we're traveling at 
about 12 clicks.

next rise, we should see homeplate . 

05 03 55 3h CDR-EVA And I think I see, on the surface here, linea- 
ments that are trending about - northwest-southeast, 
Jim. Do you get that feeling? Morton's [?] little 
lineaments . Look - look as we go across here and 
if you think ahout them, if you look down there.

this right now, and we're watching it real close, 
and we'll advise you in real time. No problem 
otherwise. It - It is good to note, though, that 
if you can do as little unnecessary moving around 
as possible, we may be able to run the EVA - EVA 
out to the full T hours. Over.

Roger, Jim. While you're working there, it looks 
like that switch is still depressed. It doesn't 
really make any difference to us, but when it 
comes time to aline the antenna, you will have to 
be careful not to point the ajitenna at any of the 
experiment tables. Over.

release it vithout that vise.

I should not point it at any of the experiments .

steer clear of.

worry about this a little later. Could you deploy 
the LR cubed for us , please? 

05 05 22 k3 CDR-EVA Sure will, Joe. But let me put the second probe 

in. I got the - the vise off, and all I got to do 
is put the probe in. Okay?

05 06 h2 38 CDE-IM Hello > Houston; Hadley Base. 

05 06 k2 hi CC Hello, Hadley Base; this is Houston. 

05 06 h2 h6 CDR-LM Roger. How is everything down there? 

05 06 h2 51 CC Dave, the dust may have settled up there; I'm not 

sure if it's settled down here. We've got more 
data than xre know what to do with at the moment. 
What can we help you with? 

05 06 i+3 02 CDR-IM Oh, Just wanted to tell you, we've got two PLSSs 

charged with 0^, one at 95 and one at 93. 

05 06 ii3 09 CC Roger. We copy that. 

05 06 k3 Ih CC Real fine day's work up there, guys. ... 

05 06 h3 21 CDR-LM Okay. Thanks, boss. 

05 06 1*3 35 CC Dave, on that PLSS reading, could you tell us 

which number belongs to which PLSS, please? 

05 06 1+3 1+3 CDR-LM We should have done that. Jim's got a 95, and 

I've got a 93. 

05 06 1+3 1*9 CC Roger, Dave. Thank you. 

05 06 1+3 56 CDR-LM Give us about 30 minutes to get a bite eat - bite 

to eat, and we'll press on for the next one. Then 
we won't have to doff the PLSSs. 

05 06 1+1+ 08 CC Dave, Deke says okay, but I'm not sure if the 

question was understood. 

05 06 1+1+ 17 CDR-LM (Laughter) Okay.

05 07 06 OU CC Roger, Dave. Just wondered how you were getting 

along up there. And If you have an estimate of 
the possible de'oriefing time» we'll shoot for that 
down here. 

05 07 06 21 CDR-LM Well, Joe, I'd like to get everything cleaned up 

in here; we got an awful lot of dirt. How ahout 
giving us an hour? 

05 07 06 31 CC Sounds good, Dave. No hurry at all. And while 

you're working around there you might be interested 
in a little conversation from down here. The SIM 
bay's chewing up data like it's going out of style. 
We're working beautifully. And, as far as we can 
determine, the ALSEP is working as advertised; 
getting all kinds of data from it, and I'll get a 
good accurate reading for that - on that for you 
later on. And I think that your traverse goes 
without comment; it was beautiful, and we're just 
trying to digest some of the data from that right 
now. 

05 07 07 18 CDR-LM Okay, I'll tell you one thing, Joe. Time sure 

goes fast out there . 

05 07 07 2h CC Yes, sir. You're not telling us anything new, 

Dave. Thank you. 

05 07 07 31 CDR-LM I - I - feel like we spent only 5 minutes at the 

Front in the whole trip. 

05 07 07 36 CC You'll get some more time a little later. Don't - 

don't worry about that. It seemed like about k and 
a half minutes to us , I think. The - the scenery 
was spe ct acular .

05 05 51 30 CMP Okay, Houston. This is Endeavour. On WIDE BEAM, 

going back to NARROW. 

05 05 51 36 CC Roger. 

05 05 51 56 CC That's sounding better, Al. How are things going 

up there? 

05 05 52 03 CMP They're going okay, Karl. Looks like I've caught 

up a little hit . Got all the dumps out of the 
way, and got the libration photography. Looks like 
I'm going to be handicapped a little bit because 
of the mission timer, but we'll press on. 

05 05 52 IT CC All right. Our understanding on the mission timer 

is, that even though you tried to reset it, it 
still refused to count up. Is that correct? 

05 05 52 26 CMP That's correct. And I thought what I'd do now is 

reset to zero and start, 

05 05 52 33 CC Roger. And for future reference, we'd like 

05 05 52 38 CMP It coionts frcan zero, Kaxl. Right? 

05 05 52 hi CC Roger - You say it is counting, but It had - it 

had - to start from zero to start counting again? 

05 05 52 50 CMP Yes. Well, let me pick a random number and see if 

it will count from there. I Just tried to tell you 
the correct times - - 

05 05 53 37 CMP Okay, Houston; Endeavour. Looks like we must have 

just run across a little funny there, Karl, be- 
cause it started okay now and is running. 

05 05 53 ^5 CC Roger. Do you have a time source, or would you 

like a hack down here to get it started again, on 
the right number? 

05 05 53 5k CMP I used the CMC time. 

05 05 53 58 CC Roger. 

05 05 5^ 38 CC And now for a future reference, we'd like to know 

whether you found the quick disconnect?

05 05 55 hi CC We copy. Al, they -want me to ask you once more 

about - tell - tell you once more where - where 
the location was. The waste management "bag in A-8, 
but I think you know that already. Incidentally, 
it's a rather short thing, 2 or 3 inches long. 
It's got a thread on one end and a quick - quick 
disconnect on the other. 

05 05 56 ok CMP Yes Karl, that's exactly what I was looking for. 

And problem is , the waste - the small waste 
management bag is not in A-5 right now. I'm going 
to have to - have to look around. Maybe Dave or 
Jim got it out on the way out. I'll look around 
and see if I can find it . 

05 05 56 18 CC Okay, fine. 

05 05 56 21 CMP I Just haven't had - haven't had the free minutes 

since they came up to do that. 

05 05 56 28 CC Right. And there's no reason now to be troubled 

by it at all. We were just asking that for future 
reference. Sounds like it's only a matter of it 
being dis - misplaced somewhere, so let's forget 
it. 

05 05 57 13 CC Endeavour, we'd like to have HIGH GAIN AUTEMA, 

AUTO. 

05 05 51 2h CMP Okay, Houston; Endeavour. You've got HIGH GAIN, 

AUTO, and I've got the PAN CAMERA POWER, on. 

05 05 57 31 CC Very good. Any time - any time on this rev, we'd 

like to have an update on the magazines. And in 
the meantime, let me give you a few good words on 
the surface activity. The boys have spent the 
last hour deploying the AI£EP , and I think all of 
the experiments got out , except we had some 
trouble, as anticipated, with the - with the drill. 
Dick Gordon is down here saying I told you so. 
The - Dave was in the process of making - for the 
world discus record, when he just about fell flat 
on his face he threw it so hard. That was - that 
was the high spot of the whole ALSEP deployment 
procedure , 



Tape 82 /2U 
Page 618 

05 05 58 19 CMP How far did he get it? 

05 05 58 23 CC Oh, I suppose we'll claim something like 2 or 

3 kilometers. Who knows for sure, (laughter) 
But the gyrations he went through to keep his 
footing after that big heave - - 

05 05 58 31 CMP Better than golf halls, even. 

05 05 58 33 CC Yes, yes. It was really funny to see him scrambling 

to keep his footing though after he swung around. 

05 05 59 ^7 CC Okay, Al. We're ready to have the PAN CAMERA 

POWER, off. 

05 06 03 05 CC Endeavour, this is Houston. You can turn PAN 

CAMERA POWER, off now. 

05 06 03 17 CMP Roger, Houston. Got it off. 

05 06 06 00 CMP Houston, Endeavour. 

05 06 06 03 CC Go ahead. Endeavour. 

05 06 06 16 CC Endeavour, this is Houston. Go ahead. 

05 06 06 22 CMP Okay, Karl. Just for your information, I finally 

dug all the way through A-8 and got a hold of the 
quick disconnect. And it's - it's as I expected 
it. But, it was there, and we're sq.uared away 
now. 

05 06 06 3^ CC Very good. That makes people feel hetter down 

here. We did stow it, after all. 

05 06 06 1+1 CMP Yes, well, one of my - one of my problems is that 

I've got the center couch underneath the right-hand 
couch, and I've also got the L-shaped bag and a few 
other things stowed on top of A-8. So, it's not 
quite so easy to get to. 

05 06 06 53 CC Right-o. We understand. 

05 06 12 30 CC Al, the boys are in the IM, and they're repres- 

Burizing the cabin now. 



05 06 12 38 CMP 



Roger, Karl. Sounds like they had a pretty good 
day.

05 06 12 h2 CC Yea, sir. They had a terrific day. I think they're 

going to sleep well tonight. 

05 06 12 51 CMP Yes. I wouldn't he surprised. 

05 06 16 33 CC Endeavour, this is Houston. You getting a good 

look at Littrow up there? 

05 06 16 ko CMP Yes, sir, I Just went by Littrov. And right over 

Serenitatis now, coming up on the landing site. 

05 06 16 h8- CC Very good. Hey, you've heen looking at Littrow 

for a couple of days now. Are you forming any 
opinions whether that dark area is lava flow or 
ash flow? 

05 06 17 03 CMP Well, Karl, if I had to give you the opinion right 

now, I'd say it was all some - some kind of ash. 
I don't - I'm not sure it's flow. But it certainly 
is - it looks like a deposit over the entire sur- 
face . You can see it - mostly in the upland areas 
Eind down in the mare areas and mostly in - in 
valleys - in depressions, this stuff seems to have 
collected almost like it was - there was some mass 
wasting down the hills making the - making the 
valleys darker in color and maybe a little thicker 
with that kind of material. But there are - there 
are still at least three different distinctive 
colorations in the Littrow area, going from dark 
gray to a sort of brownish color. And it was the 
dark gray that looked like it was an ash fault to 
me, and I'm not sure about intermediate. It looks 
more like it could have been a flow, and I can see 
even through - through the binocular I can see the 
contact where it - there's a - It looks like a flow 
front between that and the mare - the normal* mare 
coloration, which is - which is a little lighter in 
color. 

05 06 18 23 CC Okay. I guess we'd better let you go back to work 

on Hadley, which is coming up any minute now. 

05 06 18 31 CMP Roger. 

05 06 23 Oh CMP Houston, Endeavour. 

05 06 23 07 CC Go ahead, Al. 



Tape 82/26 
Page 620 

05 06 23 12 CMP Okay, Karl. I'm over the Hadley area now. I've 

gone by it. And nothing more to report on the 
Hadley , except one observation that I meant to 
mafce the last pass and didn't. I'll make it now. 
And that is that the landmark 15 — Uo is readily 
visible, even with the naked eye. You don't, need 
a sextant to see it . 

05 06 23 35 CC Very good. 

05 06 23 ^6 CC Does that secondary crater complex stand out in 

any special way that gives you some idea as to 
its origin? 

05 06 23 58 CMP Well, I didn't look at it from that standpoint 

when I was going over it before, but - I guess 
I'll have to take a special look at that to answer 
youjr q.uestion. 

05 06 3*+ 05 CO Hey, Al, how's that sunset look down below you? 

05 06 3k 15 CMP Well, I can't see it from here Karl. 

05 06 3^ 20 CC Any chance - you have got light - in the Aristarchus 

area yet? Seeing anything down there? 

05 06 3h 27 CMP Negative, Karl. I'm beyond it, and it looks like - 

I'm looking in the wrong direction anyway. Will 
say this, though. There is - there - seems to be 
a cloud that seems to be moving along with me; 
I gusss from that last dump. And it - drifted 
out. Pretty well dispersed right now, but every 
little particle of that cloud reflects the sum- 
light like a mirror. 

05 06 3^ 55 CC That's a very interesting observation. You still 

see some of it out there now, do you? 

05 06 35 04 CMP Yes, that's affirmative. I do, and - Now, I dimmed 

the lights down; I have a pretty nice view of 
the Moon in earthshine. 

05 06 35 1^ CC Ah, hah. Any chance you see Aristarchus? Are 

you, - Maybe you're not looking that way, I guess. 
Are you looking down on Aristarchus by any chance? 

05 06 35 27 CMP Well, just a second, and I'll turn the lights down 

and let you know.

Good. - That Schroter's Valley, you know, and was 
once known to glow red. 

Hello, Houston; Endeavour. 

Did you call, Al? 

Roger, Karl. I've "been sitting here looking at 
Aristarchus , and I finally had to check the map to 
make sure; because it's - it's so bright in earth- 
shine, it's almost as bright, it seems like, as it 
is in sunshine. Very, very bright crater. It 
looks very much like Copernicus at night . 

05 06 38 25 CC I'll be darned. Sounds real interesting. 

05 06 38 29 CMP Yes. And I can quite clearly trace out Schroter's 

Valley going off toward the northwest. I can't 
see it. It's a little bit out of range; it's north 
of track , and so it ' s somewhat out of range for me 
to see. 

05 06 38 kk CC Very good. Hey. Spence is asking me to remind you 

about the film magazine update if you have any time 
yet this rev. 

05 06 39 00 CMP Okay. I'm going to have to go back through the 

Flight Plan and get the numbers out. But I will 
do that. 

05 06 39 10 CC Okay. I'm not sure we want you to do that at the 

expense of anything else here, like to P52. Hang 
on. 

05 06 39 22 CMP So, I'll go ahead and do the P52, Karl. 

05 06 39 23 CC Right. We'd rather have you do the P52 if there's 

any either/or there. 

We've got your torquing angles, Al. 

Okay , Karl . Get them out in a minute . 

Hey» Al, you've got a couple of people interested 
down here in particle clouds now. And, first of 
all, we'd like to have you verify that you saw 
particles all the way until you went into the

telling me about them just as you were in that 
position. And likewise, if you have a chance at 
sunrise tomorrow where you are in that same posi- 
tion with the Sun illuminating you, hut not the 
"background, could you see if you - there is any 
remaining signs of those particles? 

05 06 k5 38 CMP Okay, he glad to. N ow, as far as how long I saw 

them; I saw them as long as the spacecraft was 
still in sunlight. However, I was beyond the 
terminator - surface terminator. And, - right now, 
looking out the window I don't see any of them. 

05 06 i+5 55 CC Okay, fair enough. And I got some words for you 

on that bad attitude that we had on the oblique 
mapping camera photography this morning. If - - 

05 06 h6 09 CMP Okay. 

05 06 h6 10 CC Evidently, we - sent you up the right attitude 

angles, but some how or other we had a - slightly 
erroneous cmicron. And, the actual photograph - 
I think we were something like 10 or 15 degrees 
off attitude - were [sic] perfectly good. No 
problem there. But, we have gone to the Flight 
Plan and made sure in the future that we will have 
the proper cmicron and everything will be right 
on the nose. 

05 06 i+6 k2 CMP Okay. 

05 06 k6 k3 CC Just in case you were wondering what in the heck 

went wrong that time. And, I have a TEI-37 any 
time you have time to copy it. 

05 06 1+6 53 CMP Okay, just a minute.

and for the Hasselhlad, mag Metro is - I've used 
155 frames; November: used 56 frames; Romeo's 
used kO frames; Sugar used 80 frames, and Nikon, 
I've used. I6 frames. And let me reverse the first 
one just to make it consistent. I've used 35 per- 
cent out of magazine Hotel for the I6 millimeter. 
That makes it all consistent.

tion window with Endeavour will open up in ahout 30 
minutes - about half an hour, and you'll have 
around 10 minutes for conversation with Al, if 
you'd like that. Over. 

05 07 30 CDR-LM We'd like that. TharJc you. 

05 07 39 CC Very good. Falcon. And any time you're interested 

in any lunchtime conversation, we've got more than 
enough to fill the square down here. 

05 07 h3 52 CDR-M Okay, Joe. We'll be giving you a call. 

05 07 ^5 57 CC Roger. And we're in no hurry.

05 07 52 38 CDR-LM Hey, Houston, we got one comment on our water 

supply here. 

05 07 52 k3 CC Go ahead. 

05 07 52 h8 CDR-LM The bacteria filter that is on the water gun, at 

some stage in the process today, got broken. It 
only has a plastic connector on it, rather than 
a metal connector, and the - the plastic connector 
chipped, and it started leaking. And we don't 
know exactly when that happened. We found it 
when we were getting ready to unsuit - when we 
were unsuit ing to get a drink. And we're not 
sure whether it spilled a fair ajnount of water 
or just the little small puddle that we have here 
on the - on the floor of the LM. Have you noticed 
any significant decrease - decrease in water 
supply? 

05 07 53 26 CC Stand by, Dave. 

05 07 53 31 CDR-LM Okay.

05 07 53 hk CDR-LM And, of course, Joe, the "bacteria filter is no 

longer usable, if anybody is worried about that. 
We're - we're not peirticularly . 

05 07 53 51 CC Roger, Dave. _\' 

05 07 5^ 5^ CC Dave and Jim, this is Houston. Our data shows no 

leeikage of water at all. We suspect that the 
little puddle you see on the floor is about all 
the water that's dripped out there. 

05 07 55 08 CDR-LM Okay. Thank you. 

05 07 55 12 CC And we also don't expect any problem on that broken 

bacteria filter, unless maybe you discovered some 
spiders and worms under the big rock you tiirned 
over. 

05 07 55 26 CDR-LM No, we're saving those for a surprise when we get 

back. 

05 07 55 30 CC They will be.

just fine. How are you doing? 

05 08 17 Ih CDR-LM How things going up there, Al? 

05 08 17 29 CDR-LM Okay. You - you're all broken up. You must be 

Just coming over those mountains again. See if 
you can see any tracks down there. 

05 08 17 it8 CDR-LM Well, we got all the way up pretty close to - we 

got to St. George, got to Elbow, and got most of 
the things done. 

05 08 18 01 CDR-LM Yes, it's pretty nice. I understand that the old 

SIM bay's gobbling up the data faster that the 
Moon can produce it. Is everything nice and clean 
up there? Boy, is it dirty down here! But we're 
going to bring this up.

That's good. Maybe - maybe you can see the 
ALSEP. 

05 08 20 U9 CDR-LM Yes, it's west about 300 feet. 

05 08 21 OU CDR-LM No, it's not very good. You're looking at best 

at something that's 2 to 3 feet. Oh, well. 

05 08 21 30 CDR-LM Well, have a nice time. We're going to go back 

to work. We'll talk to you later. Okay. 

05 08 36 i+T CC Hello, Hadley Base. This is Houston. No need 

to acknowledge. I have a report from the back 
room for you. The ALSEP has been turned on. 
We're getting a very high signal strength from 
the central station, and every experiment seaas 
to be working normally. It's an outstandir^g 
job. I thoiight you'd be interested in the fruits 
of your labors there. Over. 

05 08 37 19 CDR-LM Well, thank you, Joe. We had a good time doing it 

We'll be back with you in about - probably 10 or 1 
minutes to talk over the rest of it. 

05 08 37 28 CC Roger, Dave. We're in no hurry.

05 08 03 ho CC Go ahead. Endeavour. 

05 08 03 ^5 CMP Okay, Bob. I'm just coming over - over Picard 

at the present time, and wanted to make a comment 
that it looks like there are - there are several 
ring structures inside the - the basin itself. 
They're all concentric, and I don't see a great 
deal of relief on those that look like they're 
in the bottom of the basin. But looking at the 
- looking at the - scarps around the - the - the 
outer ring, Picard looks - looks like it's just - 
almost a caldera-type . They look almost like - 
fault plains along - along the outside. And I 
can see in the - in the - in the outer wall very 
distinct layering. For instance - the top - 
right at - right at the top is a very thin dark 
.layer, and that runs all the way around. And 
there's a light-colored layer. And then there 
are alternating dark and light layers all in 
about the same - distance from the top of the 
crater - all the way around. 

05 08 05 11 CC Roger; copy, Al. That sounds like a pretty 

complete description. 



Tape 83/T 
Page 631 



05 08 05 25 CMP And, as a matter of fact. Bob, I can make that 

same olDservation about Peirce - especially 
Peirce Alpha. This - I - I notice the same kind 
of layering and the same kind of horizontal 
lineaments in the - in the wall of the crater. 

05 08 05 51 CC Beautiful. The king '11 be proud of you. 

05 08 07 12 CMP Houston, Endeavour. 

05 08 07 Ih CC Go. 

Oil 08 07 19 CMP Okay, Bob. I'm up over Proclus now and that's one 

of the visual targets. And a couple of comments 
about Proclus, which weren't too obvious from the 
pictures we've seen before. The - the edge or the 
segment of the crater, which is in the excluded 
zone of the ray pattern - which - the ray pattern, 
by the way, is very distinct even from directly - 
directly overhead. That little segment of the 
crater wall seems to be - discontinuous with the - 
with the rest of the crater. In other words - the 

- the crater , if you - if you made a circular 

ring - and you showed that as the cra;ter, then - 
then this little chunk in that - in that quarter 
where the excluded zone is, lies outside of what 
you would describe as a circle for the crater 
itself. It's - it's like a little dimple in the 
crater itself. And I can't see anything in partic- 
ular there close to the rim that would account for 
any shadowing - any physical shadowing of the ray 
pattern. But I - I can see a diagonal fault zone 
that runs down into that little dimple that I just 
described a minute ago, and runs into that dimple 
from the east side. I couldn't pick one out on 
the west side, but it's very distinct on the east 
side. 

05 08 08 56 CC Beautiful. 

05 08 08 57 CMP And, in addition to that, I didn't see - I didn't 

see a great deal of difference in the - in the 
terrain or in the structure of the terrain across 
the excluded zone. 

05 08 09 12 CC Got it. 

05 08 12 37 CMP Houston, Endeavour. 



05 08 12 1+1 CC Go ahead. 

05 08 12 k6 CMP Okay. I'm looking right down on Littrow now, 

and a very interesting thing. I see the whole 
area around Littrow, particularly - particularly 
in the area of Littrow where we've noticed the 
darker deposits, there are a whole series of small, 
almost irregular shaped cones , and they have a very 
distinct dark mantling just around - the - those 
cones. It looks like a whole field of small cinder 
cones down there. And they look - Well, I say - I 
say cinder cones, because they're somewhat irregular 
in shape. They're not all - they're not all round - 
they're positive features - and they have a very 
dark halo, which is mostly symmetric, hut not always, 
around them individually . 

05 08 13 hi CC Beautiful, Al. 

05 08 Ik 3h CC And, Al, you might want to be reminded at this

05 08 1+9 21 CC Go ahead, Hadley Base; this is Houston. 

05 08 k9 27 CDR-LM Okay, we're all settled down now with some good 

beefsteeik, and all cleaned up and ready to talk. 

05 08 h9 36 CC SoTinds very good, Dave. We've got a list of 

questions here; some fairly general geology ques- 
tions at the last, and, depending upon your an- 
swers, we'll huild a good part of EVA-2 on it. 
Stand by a second; I've lost a lockon. Okay, we'd 
like to begin, though, with some fairly simple 
mechanical questions that'll require a ja, nein 
answer to most of them, I think. And they involve 
ALSEP and - Rover. And I'll Just - start off at 
the top of the list here. Dave, which ALSEP 
photos did you get out of the way? 

05 08 50 2k CDR-LM I got them all but the heat flow, Joe. 

05 oB 50 2T CC Roger. Copy all but the heat flow. And, Jim, 

when the LSM sunshield was deployed, do you think 
the instrument stayed more or less steady? Or do 
you think it may have moved a little bit? 

05 08 50 1*6 LMP-LM It might have moved a little, Joe, 

05 08 50 52 CC Dave, say again. I didn't copy that. 

05 08 50 5U LMP-LM Is there a problem with the - Hey, Joe, this is 

Jim. It - it might very well have moved. In other 
words, it's not level any longer? 

05 08 51 05 CC Negative, Jim. We don't necessarily know that. 

As far as we know, the data looks pretty as a 
picture. We Just want your own feel for it. 

05 08 51 2k CC In other words , we have no reason to believe it 

moved. We Just wanted to get some words from you 
on that. 



05 08 51 k3 LMP-M 



I didn't notice any movement when I deployed the 
sunscreen, Joe. 



Tape 8U/2 
Page 636 



05 08 51 ^9 CC Okay, fine. When you took the double core, did 

you notice any soil falling out of the core tubes 
while you put the caps on? 

05 08 52 OU CDR-LM Yes, there was a slight amount of loss from the 

lower and a little hit from the upper, but very 
little. 

05 08 52 11 CC Okay, that sounds good. And regarding the question 

about the Rover track, Jim, you told us they were 
one- half inch deep or less, and we're wondering if 
that was a typical number over the - the course of 
the entire traverse, as far as you could notice? 

05 08 52 3h LMP-LM Well, that was my impression. Half an inch in - 

in general, but Dave probably has another comment. 

05 08 52 hi CDR-LM No, Joe, I'd say no more than a half an inch. It 

seems to ride very lightly; I think the - the 
bearing on the surface is - is very light, and the 
wire wheels seem to work very well. They've got 
good traction, and even though the rear end did 
break away several times, it was primarily because 
of the locked-up front wheels. And I was very 
pleased with the operation. I think the thing 
performs better than we'd expected. 

05 08 53 10 CC Okay, Dave, thank you. How a series of questions 

about the heat flow. We want you first to - to 
describe the drilling characteristics, and do you 
think you're drilling into a layer of rock? Over. 

05 08 53 28 CDR-LM I'd say yes, Joe. The drilling characteristics 

are - the gradually increasing requirement for 
force to get it in are more so than any force I 
experienced in the ones in training, even though 
they had the packed soil. One time we did have 
some that was packed so tightly I couldn't even 
get it in, but that was because of the weak battery 
on the training unit at the time. The drilling, - 
it requires more and more force the deeper you get. 
And, you could probably see the TV there at the end 
on the second one, I had the second probe about 
half way in, and I was putting almost my entire 
weight. Even though it's l/6th, there was quite 
a bit of force behind that drill, much more than 
I've ever experienced in any training. And I - 
I had the impression that, yes, we're drilling 
through rock. 



Tape 8k/3 
Page 637 



05 08 29 CC Roger, Dave. We hear you on that. A similar 

question, was the drill torque high while you were 
drilling? 

05 08 5I+ 1*3 CDR-LM Well, high is a relative term. I had to maintain 

quite a hit of pressure on it to keep from heinR 
turned, but I - I tried in the 1/6 g airplane 
several times to see if it was too high that - 
or that I could - if I couldn't hold it, and I 
could always hold it. And I can hold it here, 
even though the - the torque was fairly high. 

05 08 55 03 CC Okay, Dave, that's a clear description. We know 

that the stem is loose in the hole as far as the 
rotational motion goes. We're wondering if it's 
loose in the up and down direction. Do you think 
you could pull it out? 

05 08 55 23 CDR-LM I don't know, Joe. I - I don't really know. 

05 08 55 3^+ CC Okay, Dave, copy that. Is the drill thermal 

shroud off the drill unit? 

05 08 55 kh CDR-LM Yes. You mean the small aluminum colored shroud 

that goes over the battery? 

05 08 55 50 CC That's affirm. 

05 08 55 5^ CDR-LM Yes, that's off. 

05 08 55 56 CC Okay, and were the Boyd bolt guide cups removed 

from the heat flow experiment? 

05 08 56 11 CDR-LM Gee, I guess I have to think about what you mean. 

All the Boyd bolts are off of the - the box, as 
far as I know. 

05 08 56 25 CC Okay, Dave. Our question concerns the covers for 

the Boyd bolts. They're calling them the guide 
cups down here. 

05 Oc 56 ho CDR-LM Do you mean are they off now or were they off 

when we started? 

05 08 56 k6 CC Dave, we mean are they off now. Did they fall 

away from the unit when you picked the unit up. 
It's of - of relative unimportance, really, but it 
woiild be an interesting data point.

I didn't pay much attention, Joe, but I think all 
the Boyd holts came off the heat flow, finally, 
I think. 

Okay, Dave. Thank you. Jim, was the central 
station Sun compass on the orange mark when you 
last saw it? 

Yes, it was, Joe. 

Okay, SLnd I'm sorry I skipped over a question here. 
Dave, where is the drill vise and the drill treadle 
right now, as you remember. 

The drill vise is next to the second probe, which 
is the western probe, and the treadle is at the 
point at which we parked the Rover. 

Okay, that agrees with 



- - our guess on that. Jim, once again back to 
the central station. How accurately was the bubble 
level when you saw it? 

Oh, it was within - oh, l/8th to one-quarter of 
the center. 

Okay, that sounds good to us. Could you tell us 
whether the north-facing side of the central station 
can see any portion of the RTG? 

No, it definitely cannot. Because the RTG is 
perhaps a - a little south of and east, as far 
as the central station's concerned. 

Roger, we copy that. And, Dave, could you call 
out to us the problem with yoiir yo-yo. Do you - 
and do you think it can be fixed? 

No, we looked at it when we got back in, Joe. 

The string broke at its attach point on the inside 

of the yo-yo. 

Okay, Dave and Jim, you might want to consider 
switching out the yo-yos. Jim, you may want to 
pass yours over to Dave for the next EVA. 



Tape 8U/5 
Page 639 



05 08 59 26 LMP-LM We've already done that, Joe. 

05 08 59 30 CC You're always one step ahead of me. Some quick 

questions ahout the Rover now. Could you confirm 
that battery 2 amp-voltmeter always reads zero, 
please. 

05 08 59 53 LMP-LM I guess I can't answer that, Joe. I could never 

see the amperage on - on 2 when we were driving. 

05 09 00 01 CDR-LM Yes, my answer, Joe, would be yes. I never saw 

a motion of that needle. 

05 09 00 05 CC Okay, that's good - plenty good enough for us. 

As you know, we think that you've got two good 
batteries, but possibly a failed meter there. And 
the Rover power consumption looks like it ' s right 
on the money, and we've got a lot of gas for the 
next EVA. The amp-hour meter data which we have 
does have a couple of erratic points in it. We're 
wondering if you noticed any meter-movement 
anomalies. 

05 09 00 38 LMP-LM This is Jim. I didn't notice any meter motion 

or anomalies, Joe. 

05 09 00 kk CC Okay, Jim, thank you. And we're assuming that the 

Rover is now parked facing north. Is that correct? 

05 09 00 5h LMP-LM That's correct. 

05 09 00 56 CC I could have guessed as much. And a question about 

the suspension, which sounds kind of exciting. 
Did you ever notice it hitting bottom? 

05 09 01 09 CDR-LM Yes, we hit bottom a couple of times when we hit 

a rock, and it seemed to respond fairly well. I 
mean you could Just feel that it had bottomed out. 
1 might add something else, too, on your battery 
problem, Joe. I'm sure you're right about that 
because I noticed in backing up a couple of times 
that the front wheels did drive. 

05 09 01 3^ CC Okay, interesting comment, Dave. Thank you. Wow 

we're getting on to the toughies here, and coming 
up to a very interesting one. We'd like to know 
what your best estimation of the LMs position is. 
Over. 



Tape 8U/6 
Page 6kO 



05 09 01 55 CDR-LM Stand by. 

05 09 01 57 CC And, Dave and Jim, let me give you some background 

on that. We've got several points that are in 
a very tight cluster around the first location we 
gave you. We think, however, because of boot- 
strapping a location from Elbow Crater backwards 
using the Rover navigation system, we think that 
you may be mistaking Last Crater for Index Crater. 
And I want you to consider this as you look at 
your map and think about your present position. 
Over. 

05 09 02 3k CDR-LM Ifyl 

05 09 Ok 26 CDR-LM Joe, you've stimulated an Interesting discussion. 

Give us a couple of more minutes. 

05 09 ok 35 CC We thought we might, Dave. 

05 09 ok 45 CC And - Dave and Jim, as you well know, this question 

is pretty much academic because we're - we're doinj 
great guns, no matter where your exact location is, 
and it's something we'll construct later. But 
we're interested nonetheless. 

05 09 05 07 CDR-LM Roger. 

05 09 05 20 CDR-LM Okay, Joe. How about 733 Bravo Sierra 1+? And I 

guess that's because we are on the northeast side 
of a - double crater. 

05 09 05 37 CC Voila. We understand. 

05 09 05 k3 CDR-LM Sure nice that Rover will make 12, 13 clicks, 

isn't it? 

05 09 05 kj CC That sure is, Richard's studying the maps here 

momentarily. In the meantime, could you give us - 
Just a rough guess, a quick rundown as to where 
the samples at station 1 were taken with respect 
to the rim of Elbow, and we're interested in 
distance and direction from the rim. Just a rough 
guess. 

05 09 06 17 CDR-LM Stand by. 



Tape 8U/7 
Page 61+1 



05 09 06 38 CDR-LM Okay, Joe, 709, Bravo Echo 5, and we moved out 

about 200 feet to the east of that point in picking 
up the C radial sample. 

05 09 06 5^ CC Okay, Dave, copied that loud and clear. And, by the 

way. Rover nav system gave us exactly the same 
coordinates as you just called down for your LM 
location. Interesting coincidence, or perhaps 
not a coincidence. Moving on to the next ques- 
tion. Near Elbow Crater, Dave, you mentioned that 
your footprints exposed white soil. We wonder 
if this was a common occurrence. Did you observe 
similar white soil in footprints elsewhere? Over. 

05 09 07 27 CDR-M Joe, I sort of kicked through a rim of a small, 

1-meter subdued crater; and, as I did that, I 
kicked up the white soil. And so I kicked a 
couple of more times and it spread out; and whether 
I was - breaking up a very viable rock or not , I 
don't know. But there was a couple of kickfuls 
of dirt that was white, and as we came back past 
it on the - on the return trip to the LM, why, I 
pointed it out to Jim and he saw it too. And I'm 
not sure whether that was just at that one small 
crater, which was an old crater, or whether that 
was typical of that particular area. We just 
didn't have time to look at it. 

05 09 08 12 CC Roger, Dave. Copy that. And coming back to 

station 1, Elbow Crater, could you give us a 
quick rundown on the changes in rock distribution 
around Elbow Crater and, if possible, maybe even 
the changes in rock types there. Over. 

05 09 08 3h CDR-LM Stand by 1. 

05 09 09 00 LMP-m Joe, our clocks were running pretty fast when we 

were there, and I guess - we didn't get a chance 
to look at the distribution very well. As I 
remember it, there - there were more blocks - not 
really blocks , but large fragments , on the order 
of 6 inches to a foot, more on the southern rim, 
although it wasn't really heavily concentrated; 
I'd say 10 percent of the surface at most. There 
was more on the southern rim than on the northern 
rim. And the ones we sampled all looked pretty 
much the same. As I remember, the radial sample 



Tape 81^/8 
Page 6U2 



didn't show a great difference in rock type. 
Although, as you know, we Just didn't - a chapce 
to do much - looking and thinking then. 

05 09 09 55 CC Roger, Dave. We copy that, and answers that 

question very well. But, once again, regarding 
Elbow Crater, Jim, you called out to us a "bench 
around the east side of Elbow and you were looking 
down into Elbow from higher up on the front. We 
wonder if you could compare that bench with breaks 
in the slope of the rille wall. Over. 

05 09 10 31 LMP-LM Joe, when I commented on bench there, I woiad 

estimate two or three different levels that are 
very - were very subdued possible benches in Elbow, 
and I did not see any immediate relation between 
those subdued benches in Elbow and the - the rille. 

05 09 10 55 CC Okay, Jim, copy that. That sounds very reasonable. 

We'd like to move on down towards station 2 now, 
and - and have a series of questions about sta- 
tion 2. The first one, being, what rock samples 
did you get from Station 2, and we're more inter- 
ested in the samples that did not come from the 
large boulder, but rather what other samples did 
you get there? Over. 

05 09 11 2h CDR-LM Okay, stand by. 

05 09 11 51 LMP-LM Okay, Joe, our - our sum total at Station 2 was 

two chips off the large rock, soil from the fillet, 
soil adjacent about a couple of feet away from the 
rock, soil from beneath the rock, and the double 
core, and the comprehensive. 

05 09 12 11 CC Okay, Dave, you called it right on from memory. 

That's exactly the score sheet we had. Stand by 
a second. Let me - let me read over this second 
question. Okay - - 

05 09 12 26 CDR-LM Okay, Joe. ... 

05 09 12 27 CC regarding the boulder, do you think possibly 

that the black part of the boulder might be a big 
clast in a coarse breccia? Over. 



Tape 8U/9 
Page 6k3 



05 09 12 1*5 CDR-LM No, I'm not sure, Joe. The breccia that was in 

there was glass covered, and there was an exposure 
after I took a chip out of it that was a hreccia 
not unlike ih. As a matter of fact, I'd say it 
was almost typical of lUs, but maybe only second 
or third order. There definitely was a - a 
linear - I call it a contact. Whether it might 
have been a very large clast inside a very leirge 
rock, there's no telling. But there was a definite 
line there which differentiated two types of rock 

within that big boulder, and I - I really wouldn't 
want to guess whether that was a large clast or not. 

05 09 13 28 CC Okay, Dave, sounds good. Could you tell us where 

the samples which came off the boulder were taken 
in relation to this contact that you called out on 
the boulder? In other words, where did the chips 
come loose from? Over. 

05 09 13 U8 CDR-M Okay; if you consider the boulder being divided in 

fifths, l/5th of it was a different type, 
apparently, by this sort of topographic contact. 
We took one chip from that side and one chip from 
a corner on the other side. 

05 09 Ik 06 CC We copy that; thank you. We'd like for you to sum- 

marize the relationship of mare and Apennine Front 
in the Elbow-St. George area. And, we're looking 
for any evidence whatever of a contact, an albedo 
change, or a change in coarse- frag abundance. Over. 

05 09 ih 33 CDR-LM Joe, we looked, and we discussed it before we went 

out, and we've discussed it since we came back, 
and we - we honestly didn't see anything. 

05 09 ik kZ CC Roger, Dave; and you discussed it, then, about the 

same way during the traverse. So it sounds very 
consistent to us. Do you think that you can drive 
to either Spur or to Window Crater? 

05 09 lU 59 CDR-LM Let us take a look here, quick. 

05 09 15 53 CDR-LM Well, there are a number of craters down there in 

the area of Spur and Window, and those are the only 
craters up on the Apennine Front. And there are 
several the same size as Spur and Window, which I 
think were not evident on the photography because 



Tape 81^/10 
Page 6kk 



of the - the albedo and the Sun. I think we could 
get to some of those craters, yes. I - I'm not sure 
it would be Spur or Window, "but there are some 
craters up on the side of the Front I'm fairly sure 
we could get to. 

05 09 16 20 CC Roger, Dave. Copy that. And that is exactly the 

answer we were after; not necessarily those partic- 
ular craters, but craters similar to them; and we 
understand exactly what you're saying. We'd like 
to ask, was the abundance of white and light-gray 
rocks described in the vicinity of - of Falcon 
the same seen along the entire route to St. George, 
or did this abundance of white and light-gray rocks 
seen to vary? Over. 

05 09 17 06 CDR-LM Joe, I think we have a great variety of - of frag- 
ments out here. I - I wouldn't want to pin down 
any particular type in any area until we had more 
time to look. We've got a couple of siirprises for 
you. We have one fragment on the order of 6 inches 
which is a - a fairly well rounded, highly vesicula? 
basalt with vesicles on the order of 3 millimeters 
all over it, apparently q.uite old and rounded, and 
it's a - a brown - a brownish gray. We also have a 
- a large piece of glass. Just sheer glass, appar- 
ently, which is about a foot long and about 6 inches 
wide and very rough-textured surface; and that was 
the one that was right out the front window here 
that I described yesterday. And the basalt we 
picked up halfway back when I had to change my 
seatbelt; I saw it on the ground, and I just couldn't 
resist it. And it's unlike anything you've seen 
from the Moon before as is the large piece of glass. 
And I think those are indicators, to me, that we 
have a great variety of samples out there, and we 
really need to do some good careful looking as we 
head down towards the Front, 

05 09 l8 l8 CC Roger, Dave. Read you loud and clear on that, and 

that really brings us to our last question. We're 
in the process of starting to plan your traverse 
tomorrow. It's going to be a good one. We have no 
equipment problems that we're looking at right now 
and we'd like to ask you if there 're any particular 
inputs you would like to make into the planning team 
regarding tomorrow's traverse. Over. 



Tape 8U/11 
Page 6h3 



05 09 18 1+8 CDR-LM Okay, let us talk it over a minute, please. 

05 09 20 1+1 CDR-LM Joe, ve've talked it over, and we think the best 

thing to do is to stick exactly with the plan we 
have now. I think we understand what we're looking 
for, and even though we didn't find any - some of 
the things we were looking for today, that doesn't 
mean that we won't find them as we head down to 
Front Crater. And I - I guess about the only input 
we'd have would be that, if we can msike as good a 
time on the Rover tomorrow as we did today, perhaps 
we'd have more time to sample a - a variety of 
stations along the Front and on the way back. But, 
in general, I think we'd do better if we stuck with 
our pref light - pref light plan. 

05 09 21 25 CC Right on, Dave. We copy that, and I think we're 

going that direction. Sounds good. We got a - a 
couple more general questions and then a - a comment 
about the l6-millimeter camera, and after that we're 
going to be closing up shop down here. One more 
geology question. Do you have any feel for whether 
the frags around the small fresh craters that you've 
called out to us are, in general, pieces of the 
projectile or do you think they're ejecta frags? 
Over. 

05 09 22 06 CDR-LM Well, Joe, I - we're pretty sure they're projectile 

frags, and that's when we really need to stop and 
sample. 

05 09 22 12 CC Agreed, Dave. We think the same thing here. A 

quick comment on your l6-millimeter film. We think 
that that camera, the DAC, is still in good shape. 
That MAG Charlie was a bad magazine, and we think 
you can help us out on the other magazines left 
tomorrow by advancing the film with your finger 
Just to make sure it's moving freely in the maga- 
zine before you clip it onto the camera itself. 

05 09 22 U5 CDR-LM That's a grand analysis , Joe. We're ... 

05 09 22 1+6 CC And that's something you can do while you're packing 

the STB. Can do it tonight. Over. 

05 09 22 56 CDR-LM Roger, Joe. That's - that's a good analysis. We 

took MAG Charlie and tried to run it with our fin- 
gers and it won't run. It's absolutely jammed 
right in the beginning. And we'll run the others 
through tonight to make sure they'll work. 



Tape 84/12 
Page 6U6 



05 09 23 10 CC Sounds terrific. And, Dave and Jim, we'll be 

standing lay for a crew status report. No hurry on 
that; and, as I say, we're going to close up shop 
down here. We've got more data, really, than we 
know what to do with. But we'll work hard on it 
and be hack with you in the morning. I do have 
lift-off time pad to send to you, Jim, when you're 
ready to copy. 

05 09 23 38 CDR Okay, he's got his pencil out. Go ahead. 

05 09 23 h2 CC Roger. Lift-off times: T-28, 132:17:5^; T-29, 

13l^:l6:02; T-30, 136:lU:10; T-31, 138:12:19. Over. 

05 09 2k 19 LMP-LM Okay, Joe, beginning on 28: 132:17:5^^, 13U:l6:02, 

136:lU:10, and 138:12:19. 

05 09 2k 3k CC Readback correct. Jim. You've been doing good 

work all day. 

05 09 2k 1+3 LMP-m Well, we're trying. 

05 09 2k 55 CC Roger. And, Dave and Jim, one last comment which 

we're - we're pretty awce you're aware of. We - 
we think we're looking at an EVA tomorrow that'll 
run about 6 and a half hours , about the same thing 
we did today. And we do have a few miscellaneous 
items to clean up, either - most likely at the 
end of the traverse, so it's liable to be a little 
shorter distancewise , but otherwise , other than 
that, it'll be more or less unchanged. Over. 

05 09 25 26 CDR-LM Okay, very good, Joe. By the way, did you notice 

that I had a higher 0^ usage all the way through, 

and is that why . we 're looking at 6 and a half 
instead of 7 hours? 

05 09 25 37 CC That's correct, Dave. We've got very good data 

points on you. It's a steady curve, and the 0^ 

rate is just a little bit higher than we predicted 
and from the looks of it, you've really been doing 
some work tip there. 



05 09 25 5k CDR-UM 



Well, do you have any idea why there's a rate? 
Perhaps maybe a - a zipper could be lubricated 
or - or something like that? 



Tape 814/13 
Page 6UT 



05 09 26 03 CC Dave, this - this is a metaholic curve, plain and 

simple. It's not a leak rate at all. 

05 09 26 12 CDR-LM Okay, well, I'll breath a little less tomorrow. 

05 09 26 15 CC We don't recommend that, although the Surgeon's 

working on it right now. The ntimbers though, 
actually that we're coming up with, Dave, is 
about - The two nimbers are II50 Btu's per hour, 
working, and about TOO Btu's riding. Over. 

05 09 26 1*1 CDR-LM Okay; that's a little higher on the riding than I 

think we expected, but it's sort of a - a sporty 
Job to drive this thing to make sure we don't run 
into the craters ; and if you can get that front 
steering figured out, it'll sure help. 

05 09 26 59 CC Get 6 and a half hours like you did today, guys. 

Nobody's going to complain. 

05 09 27 06 CDR-m Okay. Roger. 

05 09 27 32 CC Dave and Jim, I'm going to sign off now, and I'm 

getting excited about tomorrow's traverse already. 
And Bob's coming on. Over. 

05 09 27 hi LMP-M , Okay, Joe. You did a superfine job today, and we 

sure appreciate you keeping track of us and keep 
us going in a straight - straight line. We'll 
be looking foirward to seeing you tomorrow. 

05 09 27 50 CC Yes, sir, wouldn't miss it for. the world. 

05 09 32 38 CC And, Falcon, we'd like biomed right, please. 

05 09 32 h6 CDR-LM Okay, biomed right. There's nothing there right 

now, but we'll give it to you. 

05 09 32 50 CC Roger. Yes. We understand. 

05 10 00 13 CC And, Hadley, this is Houston. Over. 

05 10 00 23 CDR-LM Go ahead, Houston. 

05 10 00 2h CC Roger. You got 5 minutes before you have to turn

CABIN, CABIN GAS RETURN to AUTO. And the doctors 
would like a crew status report , can you believe .

that number from "01571" to "OI605." Over. 

05 09 51 06 CMP Understand. That's column Delta and octal ID 05, 

change to "OI605."

05 09 51 39 CC Okay. At - These are changes to the bistatic 

radar at 130:52, "POO at PITCH ITT degrees." And 
we're deleting the "POO at PITCH ITl," at 130 : 5 U 
there . 

05 09 52 03 CMP Okay. And what time do you want that? At 130:52? 

05 09 52 06 CC That's affirm. 

05 09 52 13 CC And at 131 - 

05 09 52 16 CMP Okay. 

05 09 52 IT CC - at 131:10, we will chajnge the VERB 1+9 maneuver 

to bistatic attitude, from "06t, ITl, 00" to 
"06t, ITT, 00." So the PITCH changes to ITT- Over. 

05 09 52 1+0 CMP Roger. Understand. Change the PITCH to ITT- 

05 09 52 1+3 CC Okay. At 131:32, we're going to change the 

NOUN T8 values. We're going to change R to 
"plus O6T.OO," That's Rg. 

05 09 53 OT CMP Okay. Understand. Change R„ from "Ol+T.50" to 

"O6T.OO." ^ 

05 09 53 1I+ CC Roger. And at 131:39, the "start auto pitch rate" 

attitude there will be the same as the VERB 1+9 
inertial attitude updated at 131:10, which means 
we'll change that to - from "iTl" on the inertial

05 09 53 Hi CMP Roger. Understand.

Tape 8U/17 
Page 651 



05 09 54 1|5 CC Roger. Yes, there is a change. 

05 09 3h 50 CMP Okay, Go ahead. 

05 09 5^+ 52 CC Roger. It's TEI-37. SPS/G&N; 37350; plus O.60, 

plus 1.01; at NOUN 33, 150:59:30.08; NOUN 81, 
plus 2979.1, minus 07^8.6, minus 0219.6; 18O, 109, 
3^+9; and the rest of the pad is unchanged. Ulleige, 
two jets for 17 seconds; and other comments - longi- 
tude at T. will be minus 179.22. Over, 

05 09 56 08 CMP Roger. Understand TEI-37 pad, SPS/G&N; 37350;

jet, 17 seconds, and longitude T. is minus 179.22. 

05 09 56 k2 CC Roger. Readback correct; and that's the end of 

the updates for the moment. 

05 09 56 kQ CMP All righty. 

05 09 57 30 CC And, Endeavour; we'd like to get the callout which 

was at 129 : 50 for the gamma ray gainstep to shield 
off. Over. 

05 09 57 51 CMP Roger; understand. 

05 09 57 52 CC And, we, - you can get that most anytime soon. 

For 10 minutes; it is not critical yet, I guess, 
as far as the start time is concerned. 

05 09 58 5U * CMP Houston, Endeavour. 

05 09 58 56 CC Go ahead, Endeavour, 

05 09 59 01 CMP Okay, the DELTA-T on the gamma ray hoom retract 

was 3 plus 07. 

05 09 59 07 CC Copy. Thank you, 

05 10 01 02 CC And, Endeavour; Houston. When you have a moment, 

HIGH GAIN in AUTO now. 

05 10 01 09 CMP Okay. Going AUTO. And do you wajit the onboard 

re ad- outs now, Bob? 

05 10 01 22 CC Yes. We'll take them. 



Tape 8U/18

05 10 01 27 CMP Okay. Crew status. Better than most, I guess. 

PRD was 23135. Batteiy C, 37; pyro bat A, 37; 
pyro bat B, 37; RCS in order, 71, 69, 70, 71. 

05 10 01 58 CC Okay, We copy all those. 

05 10 02 02 CMP Okay; and cryo fans have been cycled. 

05 10 02 06 CC Copy. 

05 10 11 21 CC Endeavour, Houston. 

05 10 11 28 CMP Houston, Endeavour. Go ahead. 

05 10 11 30 CC Roger. And the people down here are suggesting 

that on your presleep checklist, we omit the 
direct 0^ to ON for the rest of your solo flight 

because you aren't just breathing down the cabin 
that much, and I guess it will save a little bit 
of oxygen and eliminate the possibility of crack- 
ing a relief valve there . So we ' 11 delete that 
section from your - 

05 10 11 50 CMP Okay, Bob, that sounds good. I didn't notice. 

Yes, okay, I noticed last night I set it at 5.T, 
or it was very close to 6, and it didn't drop a 
bit during the day today. 

05 10 12 07 CC Roger. I guess that's what we're noticing too. 

05 10 12 ik CMP Incidentally, just going over the Littrow area 

again. I described the - what looked some - 
some, at least, fumarolic vents. They look like 
small cinder cones to me . And every time I look 
at them, they - that firms up my impression more 
and more that they're vol - volcanic cinder cones. 
Also, I noticed one rille , and I'd like to try 
and get some pictures of it here before we get too 
far away from Littrow on the next - maybe tomorrow. 
Looks very distinctly like the roof, or the - the 
top of the rille is collapsed in some places , and 
the rille is exposed in other places . 



05 10 12 59 CC 



Roger. It'll make a few theorists pretty happy 
about that . 



Tape 8U/19 
Page 653 



05 10 13 05 CMP Yes, Yes; it might - it might confirm some things 

about rilles. It's - its a little difficult to 
see whether it is in fact a collapsed feature In 
some of the - in those parts of the rille , or 
whether it's something else that I'm seeing. But 
it looks very much like portions of - the - the 
rille have a collapsed roof. And, in fact, the 
one I was looking at , works it ' s way into what 
looks like one of the - one of the ridges . It was 
very ridgy to the - to the north and then turned 
into a - a rille as it went south. 



05 10 13 U7 CC Roger. Copy. Keep talking like that, and we 

might end up going to Littrow sometime. 

05 10 13 5*+ CMP (Laughter) Yes. 

05 10 li+ 26 CC And, Al, already you've generated enough interest 

for people to ask if it's underneath you, so that 
the mapping camera might be getting it now. 

05 10 Ik 37 CMP Yes. The mapping camera should be getting it. 

05 10 II+ 1+0 CC Beautiful. 

05 10 Ik k3 CMP I suspect the - the mapping camera might not have 

enough detail to - to pick it up as well as we'd 
like. Although, I don't know, I can see it with 
the - with the 10-power binocular without any 
trouble . 



05 10 15 01 CC Copy. And, just so we don't forget it, we got 

about 3 minutes to T-start for the pan camera. 

05 10 15 13 CMP Roger. Right with you. Countdown 2:^0 now. 

05 10 15 IT CC Right on. 

05 10 19 25 CMP Okay, Houston. That - that does the pan camera 

pass over Hadley Rille, and you can let me know 
when the lens is tucked in.

And, Hadleyi this is Houston. Over. 
Go ahead, Houston . 

Roger. We noticed over the last half hour or so, 
a 25-pound drop in the water quantity. We're 
wondering if you guys have been doing something. 
Know anything about that you could clue us in on? 

Roger. We Just recharged both PLSSs. 

Roger. Was that in the last hour and a half? 

Roger. This was in about the last, oh, 30, 
UO minutes. 

Okay. Copy. 

Does that fill the gap for you? 
Houston, Hadley Base. 
Go ahead, Hadley. 

Okay. We've got a crew status report for you. 
Go ahead. 

Okay. No medication, and the PRDs on CDR is 
5019, and the LMP, 8023. Both PLES - PLSSs took 
their recharge well, and I think they're ready to 
go for tomorrow. And I guess we're done for the 
day, so we're going to roll up the shade. 

05 10 5^ ^2 CC Roger, Dave. And one last comment to give you a 

good night's sleep. That little water leak you 
guys saw when you came in the cabin this afternoon. 
Right now, our plots are showing that as 25 pounds. 
Do you guys care to make any comments about the 
size of the leak, or anything more about that? 

05 10 55 OU CDR-LM Fine. No, except that, when we got in, that 

little plastic connector on the - yes on the 
bacteria filter was broken and there was water 
]running out of it.

05 18 03 h3 CC Good morning, Falcon. This is Houston. Over. 

05 18 03 56 CDR-LM Morning, Houston. This is Falcon. 

05 18 0^4 00 CC Roger, Falcon; Houston. Loud and clear. And 

when you're up and ready to converse, let me 
know. 

05 18 OU 11 CDR-LM Okay, Gordo. Will do. 

05 18 OU 15 CC ... First thing we've "been concerned ahout - I 

guess we'll start off with this is, according to 
our data, you lost about 25 pounds of water during 
the post- EVA yesterday, and, we - it - it appears 
that it leaked out during that problan you had 
with the broken bacteria filter. What we're 
wondering is if you've looked around carefully 
in the cabin, and noticed any sign of that 25 
pounds of water. We suggest looking back behind 
the ascent engine cover, because it possibly 
would have run back there and not have been 
obvious to you. Over. 

05 18 05 08 CDR-LM Okay. There was some on the floor in the . . . 

deck, and we just never took the time to take a 
look in the back, but we will. 

05 18 05 16 CC Okay. If you find - any water back there, we 

have some suggestive procedures to clean it up, 
and we'd like to do that before depressurization. 

05 18 05 33 CDR-LM Roger. Will do. 

05 18 10 56 CDR-LM Oh, Houston, Falcon. Yes, we do have a little 

puddle of water back in the - behind the ascent - 
behind the engine cover.

05 18 11 l8 CC Okay, Dave. Oirr suggested procedure for collecting 

that will be to remove the netting and whatever is 
required to get down to it. Use a used food bag 
as a scoop if it's a deep enough puddle to scoop 
it up and take one of the used LiOH containers 
that contains a used cartridge that's in the buddy 
SLSS bag now that's scheduled for the upcoming 
jettison. Take the LiOH cartridge out of the con- 
tainer, then use the container itself to hold the 
water as you scoop it up with the food bag. And 
then when you get down to the point where you can 
no longer get any more water, use utility towels 
to mop up the rest. Over. 

05 18 12 01 CDR-LM Okay. We'll do our best. 

05 l8 12 05 CC And if one of you is not - busy,
