Caption:
12 June 2006
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a group of impact craters in Aonia Planum, Mars. Remarkably, two of the craters are approximately equal in size, however, they clearly differ in age. The left (west) crater has a well-defined rim and its ejecta blanket overlies part of the less pronounced crater to its immediate east. The one with the ejecta blanket is younger. Other circular depressions in this bouldery scene are also old, eroded impact craters.
