NASA Mars Reconnaissance Orbiter HiRISE Images: March 26, 2014

– A Dark-Toned, Pitted Mound in a Crater in Northeast Arabia Terra http://hirise.lpl.arizona.edu/ESP_034970_2040

This fascinating observation shows us a dark-toned mound with pits inside an impact crater. Are these pits the result of sublimation?

– A Large, Banded Angular Fragment in Nili Fossae http://hirise.lpl.arizona.edu/ESP_035062_1995

HiRISE images of similar fragments nearby also show this banding, and the resolution of our camera may help determine what these layers are.

– An Unusual Mound http://hirise.lpl.arizona.edu/ESP_035078_2185

With its cracked, blistery appearance, this mound near the center of a very large crater poses an interesting question: how did this form?

– Bedrock in a Trough in Asimov Crater http://hirise.lpl.arizona.edu/ESP_035777_1320

The crater appears to have been completely filled by a thick sequence of materials, perhaps including sediments and lava flows.
