Rembrandt Revisited


This limb image shows Rembrandt, the second largest impact basin on Mercury after Caloris. Discovered during the second MESSENGER flyby, Rembrandt is one of the youngest impact basins on Mercury, as indicated by the relatively low density of impact craters on its rim. A large lobate scarp trending from the southwest to the north crosscuts Rembrandt and several of the smaller craters that have impacted the smooth interior plains.
