NASA Mars Reconnaissance Orbiter HIRISE Images January 18, 2012
– Many Fantastically Colorful Gullies in a Fresh Impact Crater http://hirise.lpl.arizona.edu/ESP_024927_1445
This is an especially pristine crater so the slopes may be particularly steep and unstable.
– Gullies in Bamberg Crater http://hirise.lpl.arizona.edu/ESP_024951_2200
These gullies are of particular interest since there appears to be very little material accumulated on the floor here, unlike other craters with gullies.
– Tongue-Shaped Flow Below a Scarp in Phlegra Montes http://hirise.lpl.arizona.edu/ESP_024958_2150
The source of the material and how it was deposited here remains unclear: debris flow, landslides, or a flow of ice-rich material?
– The Floor of Beer Crater http://hirise.lpl.arizona.edu/ESP_025136_1650
This crater was named after German astronomer Wilhelm Beer. It is an ancient crater more than 100 kilometers across, located south of Meridiani Planum.
