NASA Mars Reconnaissance Orbiter HiRISE Images: July 2, 2014

– A Giant Cave on a Giant Volcano http://hirise.lpl.arizona.edu/ESP_023531_1840

From this digital terrain model, we can measure how much material drained out of the conical pit and so estimate how tall the debris pile is.

– Feathery Ridges http://hirise.lpl.arizona.edu/ESP_036485_1765

It is common for sand dunes to be covered in small ripples, often with different orientations that may be shaped by wind.

– A Revealing Landslide in Hebes Chasma http://hirise.lpl.arizona.edu/ESP_036927_1790

Exposures of layered rock like these are helpful in determining the types of geologic processes that have occurred at an area over time.

– An Impact Crater in Isidis Planitia http://hirise.lpl.arizona.edu/ESP_036934_1915

This location is also the site of an early candidate for location of the Beagle 2 lander based on an image from the Mars Global Surveyor.
