This color-coded elevation map of the local terrain on the north side of NASA's Phoenix Mars Lander shows the contours of polygons and relationship of polygon boundaries to trenches and other features in the workspace of the lander's Robotic Arm.
The map covers an area about 4 meters (13 feet) across. Areas coded red, yellow and green are higher than areas coded blue and purple.
The Phoenix Mission is led by the University of Arizona, Tucson, on behalf of NASA. Project management of the mission is by NASA's Jet Propulsion Laboratory, Pasadena, Calif. Spacecraft development is by Lockheed Martin Space Systems, Denver.
