NASA Mars Reconnaissance Orbiter HiRISE Images - September 19, 2012

Status Report From: Jet Propulsion Laboratory
Posted: Friday, September 21, 2012

- Unusual Crater with Lava Flows Near Arsia Mons http://hirise.lpl.arizona.edu/ESP_017347_1585

The origin of this structure is unclear but may be related to the breach in the crater rim to the left.

- A Small, Double-Ringed Crater http://hirise.lpl.arizona.edu/ESP_028162_2310

The impact penetrated through the material and into the substrate and formed this "double crater" as it excavated material from these two layers of different strengths.

- Clay Color Inspiration http://hirise.lpl.arizona.edu/ESP_028367_2085

The relatively bright areas reveal a complex terrain with a range of textures and enhanced colors.

- Cratered Cones in Grojta Valles http://hirise.lpl.arizona.edu/ESP_028466_1955

These cones are interpreted to be the product of explosive lava-water interactions, indicating that the region is covered by lava.
