\nNASA\u2019s Mars Reconnaissance Orbiter used its Context Camera to capture this image of Bosporos Planum, a location on Mars. The white specks are salt deposits found within a dry channel. The largest impact crater in the scene is nearly 1 mile (1.5 kilometers) across.

Caltech researchers used the Mars Reconnaissance Orbiter to determine that surface water left salt minerals behind as recently as 2 billion years ago.<\/p>\n
Mars once rippled with rivers and ponds billions of years ago, providing a potential habitat for microbial life. As the planet\u2019s atmosphere thinned over time, that water evaporated, leaving the frozen desert world that NASA\u2019s Mars Reconnaissance Orbiter (MRO) studies today.<\/p>\n
MRO has two cameras that are perfect for this purpose. The Context Camera, with its black-and-white wide-angle lens, helps scientists map the extent of the chlorides. To zoom in, scientists turn to the High-Resolution Imaging Science Experiment (HiRISE) color camera, allowing them to see details as small as a Mars rover from space.<\/p>\n

JPL, a division of Caltech in Pasadena, California, manages the MRO mission for NASA\u2019s Science Mission Directorate in Washington. The University of Arizona, in Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., in Boulder, Colorado. MARCI and the Context Camera were both built and are operated by Malin Space Science Systems in San Diego.<\/p>\n
