This color image was acquired by the Surface Stereo Imager on NASA's Phoenix Mars Lander on the 25th day of the mission, or Sol 24 (June 19, 2008).

It shows lumps of ice in the lower left corner of a trench nicknamed "Dodo-Goldilocks." These lumps later sublimated, a process similar to evaporation, over the course of four days.

Figures 1 and 2 show sublimation of ice in the trench informally called "Dodo-Goldilocks" over the course of four days.

In the lower left corner of the left image of figures 1 and 2, a group of lumps is visible. In the right image, the lumps have disappeared, similar to the process of evaporation.

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.
