Scientists scouting potential landing sites for NASA's next Mars rover mission are using new data from a powerful mineral-mapping camera to narrow the site selection.

Less than a year since beginning the prime science phase of its mission, NASA's Mars Reconnaissance Orbiter has passed a mission-success milestone for the amount of data returned.
