NASA Mars Reconnaissance Orbiter HiRISE Images: January 22, 2014

– Light-Toned Deposits along Coprates Chasma Slopes http://hirise.lpl.arizona.edu/ESP_034329_1670

This region of Mars contains kilometers-thick light-toned layered sedimentary deposits along many of its floors.

– Shapes and Spots on a Polar Sand Dune http://hirise.lpl.arizona.edu/ESP_034441_2565

This observation shows numerous dark shapes and bright spots on a sand dune in the Northern polar regions of Mars.

– Oxus Patera Collapse Feature http://hirise.lpl.arizona.edu/ESP_034656_2195

It’s unknown how Oxus Patera formed, although some suggest it represents an ancient caldera formed by collapse and explosive volcanism.

– Giant Gullies North of the Argyre Impact Basin http://hirise.lpl.arizona.edu/ESP_034829_1325

Even by Martian standards, the gullies in this observation are quite large.
