This week the Astrobotic team deployed Red Rover's third prototype in a Pittsburgh-area slag heap to begin evaluating its ability to handle outdoor terrain with loose rocks and challenging slopes. (Slag heaps are fields of waste rock left over from the refining of iron ore at steel mills.) This lunar-like terrain enabled a great photo and video shoot. In this photo, the five-foot tall robot is sidelighted as it will be upon landing shortly after dawn on the Moon. The solar cells will be generating 120 watts to power Red Rover's two driving/steering motors, its computers, three cameras and radio transceiver.
