NASA Mars Reconnaissance Orbiter HiRISE Images – May 29, 2013

– Endeavour Crater Western Rim http://hirise.lpl.arizona.edu/dtm/dtm.php?ID=ESP_018701_1775

This digital terrain model covers the western rim of Endeavour Crater where the Mars Exploration Rover Opportunity has been investigating since 2011.

– Active Slope Flows on the Central Hills of Hale Crater http://hirise.lpl.arizona.edu/ESP_031203_1440

In some cases, there are many seasonal flows on warm slopes, suggesting some role for water in their activity.

– Crater with Debris Aprons in Tyrrhena Terra http://hirise.lpl.arizona.edu/ESP_031805_1545

The interior rims of this crater are lined with debris aprons consisting of material eroded from the alcoves at the top of the crater walls.

– Valleys in Tyrrhena Terra http://hirise.lpl.arizona.edu/ESP_031817_1410

These valleys are very different in appearance compared to the very old, large, and well-developed valley networks on Mars.
