The Surface Stereo Imager (SSI) on NASA's Phoenix Mars Lander took this
shadow-enhanced false color image of the "Snow White" trench, on the
eastern end of Phoenix's digging area. The image was taken on Sol 144, or
the 144th day of the mission, Oct. 20, 2008. Temperatures measured on Sol
151, the last day weather data were received, showed overnight lows of
minus128 Fahrenheit (minus 89 Celsius) and day time highs in the minus 50
F (minus 46 C) range. The last communication from the spacecraft came on
Nov. 2, 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.
