JPL engineers examine the robotic arm of Mars Exploration Rover 1. The arm
is modeled after a human arm, complete with joints, and holds four devices on
its end, the Rock Abrasion Tool which can grind into Martian rocks, a microscopic
imager, and two spectrometers for elemental and iron-mineral identification.
