Engineer Checking Robotic Arm of Phoenix Lander
NASA's Phoenix Mars Lander has a scoop on the end of its Robotic Arm. A motor-driven rasp can be lowered at an angle through a small opening in the bottom of the scoop to aid in gathering shavings of hard-frozen material. In this image, Lori Shiraishi, an engineer at NASA's Jet Propulsion Laboratory, inspects the scoop while the spacecraft was being assembled and tested before its Aug. 4, 2007, launch.
