A New Impact Marking Fades Away
A New Impact Marking Fades Away
ESP_062948_2175  Science Theme: Impact Processes
A HiRISE observation in 2010 covered a new impact crater that formed after December 2007 and before August 2010, based on Context Camera images. HiRISE has been re-imaging these sites to see how rapidly the dark ejecta and blast zone markings disappear as dust is deposited or redistributed.

An animation compares the two images and shows that the dark material has faded into the background, while the new 6.3-meter diameter crater persists.
