'Dodo-Goldilocks' Trench Elevation Map
Date: 13 Jun 2008

This color-coded elevation map shows the "Dodo-Goldilocks" trench dug by the Robotic Arm on NASA's Phoenix Mars Lander. The trench, originally two separate trenches nicknamed "Dodo" (left) and "Goldilocks" (right), became one after further digging on the 18th Martian day, or Sol 18, of the mission (12 June 2008). The trench is 7 to 8 cm (2.7 to 3 inches) at its deepest (blue). Because the terrain itself is inclined at a 14-degree angle, the highest areas (pink) are about 20 cm (7.8 inches) above the lowest areas.


The trench is 22 cm (8.7 inches) wide and 35 cm (13.8 inches) long. Its deepest portion is closest to the lander.


This picture was taken by Phoenix's Surface Stereo Imager on Sol 19 (13 June 2008).


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.
