Lights OFF - Sol 116 (approximate colors; credits: NASA)

CAption NASA:"This approximate color image is a view of NASA's Phoenix Mars Lander's Robotic Arm Camera (RAC) as seen by the Lander's Surface Stereo Imager (SSI). This image was taken on the afternoon of the 116th Martian day, or Sol, of the mission (such as September 22, 2008). The RAC is about 8 cm (3" - inches) tall.

The SSI took images of the RAC to test both the light-emitting diodes (LEDs) and cover function. Individual images were taken in three SSI filters that correspond to the red, green, and blue LEDs one at a time.
This yields proper coloring when imaging Phoenix's surrounding Martian Environment".
