NASA is working on the building blocks to return humans to the Moon by 2020 and then send them onto Mars. It is part of the national Vision for Space Exploration established five years ago. Just what is America's plan and is it the right one? Four international experts addressed those questions and others in a special Moon-Mars Forum, March 17, from 7-9 p.m. at the Virginia Air & Space Center in downtown Hampton, Va. The National Institute of Aerospace (NIA) and NASA Langley Research Center's Systems Analysis and Concepts Directorate hosted the panel discussion that featured Dr. Scott Pace and Dr. Paul D. Spudis, leading authorities on lunar science, engineering and space policy; and Dr. G. Scott Hubbbard and Dr. Joel S. Levine, experts on Mars science, engineering and policy. Dr. Douglas Stanley, visiting professor from Georgia Tech at NIA, moderated the forum.
