The first color image to come from a camera aboard the ExoMars Trace Gas Orbiter in its Mars-mapping orbit shows the ice-coated rim of Korolev Crater in sharply shadowed detail.

“We were really pleased to see how good this picture was, given the lighting conditions,” Antoine Pommerol, a member of the science team for the Color and Stereo Surface Imaging System, said today in a news release. “It shows that CaSSIS can make a major contribution to studies of the carbon dioxide and water cycles on Mars.”

The ExoMars Trace Gas Orbiter, a mission jointly supported by the European and Russian space agencies, is built to measure the composition of Mars’ thin atmosphere with unprecedented accuracy. Its top task is to look for methane and other trace gases that could hint at biological or geological activity.
