Phobos up close and very personal

Mars has two dinky moons, Phobos and Deimos. That’s the creepily good HiRISE camera from the Mars Reconnaissance Orbiter, of course, that took the image. Click it to embiggen and get much higher-res versions: the raw data has a resolution of 7 meters per pixel. There have been more detailed images taken in the past, but these collected more light from the tiny moon and so have better quality. The crater Stickney on the right is huge compared to the moon; if the impactor had been any bigger or moving faster it would have shattered the moon.
