Early in the Mars Global Surveyor mission, the MOC saw gullies (like the thin white streak at center) that seemed to be geologically young -- young enough that some might even be active today. The scientists at Malin Space Science Systems (MSSS) monitored hundreds of these gullies to see if any changed over time. Two of them did, including this one, which appeared different in photos taken in December 2001 and April 2005. Some Mars scientists suspect that liquid water may have flowed in this gully very recently -- within a decade.
