Filed under pretty pictures, amateur image processing, Mars, Mars Reconnaissance Orbiter
Another gem discovered in the latest release of images from the Mars Reconnaissance Orbiter. At 3:49 pm local time on Halloween of last year, the clouds parted just enough for the HiRISE camera to glimpse these gullies in the wall of an unnamed crater in the southern highlands.

Gullies like these fascinate Mars explorers because some of them are thought to seep with liquid water from underground aquifers.
