Fresh, But Not So Clean

LROC NAC image M131515002R showing two similarly sized craters, ~500 m in diameter, but one is littered with boulders and the other is not.  This boulder discrepency is most likely due to age differences between the two craters....

Rough Around the Edges

With peppered flanks, Rima Suess wanders over 150 km through Oceanus Procellarum. The rocks that rest on the walls of this lunar rille are perhaps remnants of much larger boulders that have eroded down to meter sized rocks due to micro...
