A New Crater on a Dusty Slope
NASA - Mars Reconnaissance Orbiter (MRO) patch.
Feb. 21, 2017
This image shows a new impact site originally detected by the Context Camera onboard MRO. The crater is on a dusty slope, which also has several dark slope streaks due to dust avalanches.
A previous impact at another place on Mars triggered a major dust avalanche, but this one did not. This tells us that the dust here is more stable (stronger and/or on a lower slope).
The map is projected here at a scale of 25 centimeters (9.8 inches) per pixel. [The original image scale is 27.1 centimeters (9.8 inches) per pixel (with 1 x 1 binning); objects on the order of 81 centimeters (30 inches) across are resolved.] North is up.
