Guests: Wil Simon and Matt Everingham were the guests for this Space Show program in order to discuss the upcoming NASA 2008 Regolith Excavation Challenge from August 2-3, 2008 in San Luis Obispo, CA on the campus of Cal Poli. Wil and Matt explained the competition, some of the rules, and fielded lots of listener questions ranging from He3 to telling us about the judges for the contest.
