Seeing through the Dusty Air
ESP_056190_2235  Science Theme: Impact Processes
Mars has recently been enveloped in dusty haze, but the sensitivity of HiRISE enabled imaging of surface features through a moderate level of haze.

This image shows a fresh impact crater in the northern middle latitudes. A technique called “pixel binning” was needed to improve the signal, but it is still the highest-resolution image ever acquired at this location.

*Pixel binning combines information of adjacent detectors in a CCD camera sensor to create one single pixel in the recorded image.
