NASA Mars Reconnaissance Orbiter HiRISE Images – May 9, 2012

– Naar Crater http://hirise.lpl.arizona.edu/ESP_025691_2030

This impressive crater, that stretches well across the width of the HiRISE camera’s footprint, is notable for its sharp rim and steep walls.

– A Youthful Crater and Its Ejecta http://hirise.lpl.arizona.edu/ESP_026099_2320

Given the latitude and proximity to gullies on mesas and massifs in this region, there could also be mid-latitude-type gullies in this crater.

– Sculpting Dunes in Ganges Chasma http://hirise.lpl.arizona.edu/ESP_026100_1725

When dunes are located in a complex topographical area such a canyon, they become ideal candidates for detecting changes to their shapes and sizes over time.

Mars is very different from Earth in that its main atmospheric component can condense onto the surface.
