Robotic Arm Camera (RAC)

NSSDCA ID: 2007-034A-02

Mission Name: Phoenix Mars Lander


The Robotic Arm Camera (RAC) is designed to provide close-up images of the martian surface in the vicinity of the lander, prospective samples in the trench dug by the robotic arm, the robotic arm scoop to verify the samples have been collected for MECA and TEGA anlysis, and the edges and bottom of the trench. The RAC is a box-shaped device mounted on the robotic arm just above the scoop. It is a CCD system with a double Gauss lens system protected by a movable transparent lens cover and two illumination assemblies. The focus can be adjusted from 11 mm to infinity with resolution up to 23 microns per pixel.
