NASA Mars Reconnaissance Orbiter HiRISE Images – June 20, 2012

– Rough Surfaces in Deuteronilus Mensae http://hirise.lpl.arizona.edu/ESP_025174_2245

The objective of this observation is to examine what may be formerly ice-rich terrain that has just lost ice to the atmosphere.

– Exploring Antoniadi Crater http://hirise.lpl.arizona.edu/ESP_025331_2005

Antoniadi Crater was identified, even prior to the MRO mission, as a likely ancient lake (now dry) that was supplied by both surface water and ground water.

– Ridges in Meridiani Planum http://hirise.lpl.arizona.edu/ESP_025386_1800

When terrain gets squeezed by geologic forces deep rocks sometimes break and get pushed upwards forming raised wrinkles on the surface.

– Colorful Layers in Nili Fossae http://hirise.lpl.arizona.edu/ESP_026992_2025

This enhanced-color version of the central part of the HiRISE image shows colorful layers that may contain carbonate minerals.
