HiRISE has been imaging new dark features discovered by MRO's Context Camera, which are mostly new impact sites. In this scene we see what appears to be a new impact cluster and, extending downhill from the craters, new dark slope streaks .
These slope streaks are formed by dry dust avalanches. We've also seen large new dust avalanches associated with new impacts at previous locations .
The map is projected here at a scale of 25 centimeters (9.8 inches) per pixel. (The original image scale is 28.9 centimeters [11.4 inches] per pixel [with 1 x 1 binning]; objects on the order of 87 centimeters [34.3 inches] across are resolved.) North is up.
Background Info:
The University of Arizona, in Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., in Boulder, Colorado. NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Mars Reconnaissance Orbiter Project for NASA's Science Mission Directorate, Washington.
