Four Antarctic explorers (Charles Bentley, Richard Cameron, Mario Giovinetto, and Charles Swithinbank) were invited to a workshop at Johnson Space Center (JSC) to provide expert assessments of NASA's current understanding of future human exploration missions beyond low Earth orbit.

This report records their observations about these facilities and plans in answers to a series of questions provided to them before the workshop.
