Digging for Dollars on the Moon: The Lunar Regolith Challenge

Join the fun as we provide special coverage of the NASA Centennial Challenge that brought robot excavators to central California in mid-May. They competed for a $250,000 prize. All they had to do was move a lot of simulated lunar soil in a half-hour without human guidance, with very little power, and with several other limitations. Then find out what's in the current night sky from Bruce Betts, and learn how to win a Planetary Radio t-shirt from Bruce and Mat.
