The third prototype for Astrobotic Technology’s lunar robot has innovations that will enable it to survive the blistering heat at the Moon’s equator, which is the robot’s destination in May 2011 when it will visit the Apollo 11 site.

Noon at the equator is hotter than boiling water: 270 degrees F. The robot beats the heat by keeping a cool side aimed away from the Sun to radiate heat off to the black sky. It travels toward or away from the sun (generally east or west) without turning its radiator into the light. Only the solar cells on the hot side ever face the sun. The robot can travel north and south by tacking like a sailboat.
