HiRISE Views a Cluster of Impacts on Mars

New Image Shows a Recent Cluster of Impacts on Mars

This new HiRISE picture shows a new cluster of impacts on Mars.

The dim spots in this enhanced-color infrared picture are a new impact craters that occurred in a Tharsis segment between 2008 and 2014. These impact craters were initial detected by a Mars Context Camera (or CTX, also onboard a Mars Reconnaissance Orbiter) as a cluster of dim spots. The meteoroid that shaped these craters contingency have damaged adult on windy entrance and fragmented into dual incomparable masses along with several smaller fragments, spawning during slightest twenty or so smaller impact craters.

The dim halos around a ensuing impact craters are a multiple of a light-toned dirt being privileged from a impact eventuality and a deposition of a underlying dim toned materials as void ejecta. The placement and a settlement of a rayed ejecta suggests that a meteoroid most-likely struck from a south (which is adult in a cutout).

HiRISE frequently monitors new impact craters identical to this one; however, this is a initial picture of this sold impact taken by HiRISE, interjection to a ask by a CTX team. Subsequent images will expected follow to guard if there are any changes to a site from wind-blown activity or dust-deposition over time.
