HiRISE: Bang and whoosh!

This HiRISE image captures a new, dated (within about a decade) impact crater that triggered a slope streak. When the meteoroid hit the surface and exploded to make the crater, it also destabilized the slope and initiated this avalanche. The … Continue reading

HiRISE: New impact site in southern mid-latitudes

Over 500 new impact events have been detected from before-and-after images, mostly from MRO’s Context Camera, with a HiRISE followup. Those new craters that expose shallow ice are of special interest, especially at latitudes where not previously detected, to better … Continue reading

HiRISE: New crater on a dusty slope

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 … Continue reading

HiRISE: Cluster of recent impacts

The dark spots in this enhanced-color infrared image are the recent impact craters that occurred in the Tharsis region between 2008 and 2014. These impact craters were first discovered by the Mars Context Camera (or CTX, also onboard the Mars … Continue reading

HiRISE: Looking for ice

One of MRO’s ongoing campaigns is a search for new impact craters. At high latitudes, such craters often expose ice, which appears bright in HiRISE enhanced-color images. This image was targeted to look at a candidate new crater on a … Continue reading
