NASA Mars Reconnaissance Orbiter Images: November 6, 2013

– Hints of an Ancient Shoreline in Southern Isidis Planitia http://hirise.lpl.arizona.edu/ESP_033242_1845

 

This area–known as the Deuteronilus contact of the Isidis Basin– has been interpreted as a possible ancient shoreline.

 

– Breached Rim of a Circular Depression http://hirise.lpl.arizona.edu/ESP_033243_2165

 

This observation shows a partially-filled impact crater with sediment flow that has breached the south rim.

 

– Cratered Cones in Tartarus Montes http://hirise.lpl.arizona.edu/ESP_033252_2070

 

While most craters on Mars are generated by impacts of asteroids and comets, another process might have been at play here.

 

– Dust Covered Channels on Tharsis Tholus http://hirise.lpl.arizona.edu/ESP_033565_1945

 

The flanks of Tharsis Tholus are cut by large channels, similar to those visible on other Martian shield volcanos like Arsia Mons and Elysium Mons.
