Like a Rolling Stone

A boulder leaves a bounding trail in the lunar dust

Here’s a neat image for today: a detail of the central peak of Eratosthenes Crater, taken by the Lunar Reconnaissance Orbiter Camera (LROC), shows a trail a rolling boulder has left in the regolith (the fancy word for Moon dirt.) The boulder, located in the central part of the top half of this image, came loose at some point in the past, leaving regularly-spaced depressions behind it as it tumbled and bounced downhill in the low lunar gravity.

This image spans a distance of about 600 meters (just under 2000 feet).

See this image and more on NASA’s LRO mission site here, or on the University of Arizona’s LROC imaging site here.
