NASA Mars Reconnaissance Orbiter HiRISE Images – August 15, 2012

– Bright and Dark Slope Streaks in Arabia Terra http://hirise.lpl.arizona.edu/ESP_022405_1910

While HiRISE has imaged slope streaks before, bright strikes are not as common as dark ones, so they’re of high interest.

– A Pedestal Crater in Malea Planum http://hirise.lpl.arizona.edu/ESP_022787_1085

Pedestal craters are the remnants of geologic units that have been heavily eroded from the surface of Mars.

– On the Hunt for New Impact Craters http://hirise.lpl.arizona.edu/ESP_027077_1785

In this observation, we see a dark spot with a larger, rayed “blast zone” that was also apparent in a Context Camera image taken in 2011, but not in 2009.

– Dune Migration http://hirise.lpl.arizona.edu/ESP_028020_2560

In addition to migration of the dune, we will also use these repeat images to look for changes in the dune shape and avalanches down the slip face.
