NASA Mars Reconnaissance Orbiter HiRISE Images: August 13, 2014

– Glaciation at the Eastern Hellas Margin http://hirise.lpl.arizona.edu/ESP_036947_1390

 

Hellas Crater in the ancient highlands contains some of the clearest evidence on Mars for glacial processes.

 

– The Side of Chasma Boreale http://hirise.lpl.arizona.edu/ESP_037056_2650

 

Comparing images like this to those taken in previous years and in different seasons allows a more accurate understanding of current surface processes on the Red Planet.

 

– An Irregular, Upright Boulder http://hirise.lpl.arizona.edu/ESP_037190_1765

 

The trail has a odd repeating pattern, as if the boulder couldn’t roll straight due to its shape.

 

– Strange Cones and Flows http://hirise.lpl.arizona.edu/ESP_037222_1820

 

The shapes of these regions are unusual, and the association with cones suggest that the cones were source vents for local lava flows.
