Fresh Crater with Gullies
Date: 8 Jun 2007
This observation from Mars Reconnaissance Orbiter's High Resolution Imaging Science Experiment (HiRISE) instrument shows a fresh, approximately 7.5 km diameter crater that resides in a larger crater in the southern hemisphere.
This crater has few craters superposed on it, which attests to its youth. It also has very steep slopes and a sharp rim; more evidence of its young age. Young, fresh craters are of interest on Mars because they help place constraints on the rate at which new impact craters and other young features have formed in recent times.
