The bright rocks in this image have minerals that contain water. These water-bearing minerals are found using the companion instrument on the MRO spacecraft called CRISM. By combining the spectral data from the CRISM instrument with the high resolution visible images taken by HiRISE, scientists are able to speculate how water deposited and/or altered these rocks… [More at link]
