New Impact Crater (ESP_019195_2175)

The MRO Context camera team noticed a dark spot in an image taken in
August 2010 that was not present in a Mars Odyssey THEMIS image taken
in December 2007.
The team therefore requested a full-resolution HiRISE image of the dark
spot to determine whether it was caused by an impact. Indeed, the HiRISE
image shows an approximately 7 meter-diameter fresh crater and dark
ejecta blanket at this location. These small impact craters continue to
form on Mars, and are most easily recognized in areas covered by bright
dust.
