Did you catch this HiRISE image from the Mars Reconnaissance Orbiter last week? As the spring thaw at the north polar cap destabilized some soil on a half-mile cliff face, MRO took in the action.
This is the featured image today at the Astronomy Picture of the Day site. Even if you’re not an astronomy buff, the site is well worth bookmarking for the beauty of the images. The science is good, too.
