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.
