Saltland, in natural colors (2) - Sol 788

Caption NASA originale:"Spirit's PanCam and Miniature Thermal Emission Spectrometer examined this most recent discovery, and researchers will compare its properties with the properties of those other deposits.
These discoveries indicate that salty, light-toned soil deposits might be widely distributed on the flanks and valley floors of the Columbia Hills Region in Gusev Crater.
The salts, which are easily mobilized and concentrated in liquid solution, may record the past presence of water. So far, these enigmatic materials have generated more questions than answers, however, and as Spirit continues to drive across this Region in search of a safe Winter haven, the team continues to formulate and test hypotheses to explain the Rover's most fascinating recent discovery.

This view is an approximately true-color rendering that combines separate images taken through the PanCam's 753-, 535- and 432-nanometer filters".
