NASA Mars Reconnaissance Orbiter HiRISE Images - December 5, 2012


- Impacts from MSL Tungsten Blocks and Cruise Stage http://hirise.lpl.arizona.edu/ESP_029245_1755

MSL (Curiosity) in cruise configuration jettisoned two 75-kilogram tungsten blocks just before atmospheric entry, used as cruise balance masses.

- Columnar Jointing on Mars and Earth http://hirise.lpl.arizona.edu/ESP_029286_1885

Finding evidence for large amounts of liquid water on Mars is important for understanding the planet's climate history and habitability.

- Colorful Fractured Bedrock in Ritchey Crater http://hirise.lpl.arizona.edu/ESP_029542_1510

The dark, ridgelike lines that cut across the colorful blocks may be dikes, formed when molten rock forced its way into pre-existing linear fractures in the surrounding rock.

- Apostrophe Dunes http://hirise.lpl.arizona.edu/ESP_029660_1350

The lack of symmetry within these dunes tells us that there is more than one wind direction acting here.
