NASA Mars Reconnaissance Orbiter HiRISE Images - May 15, 2013

Status Report From: Jet Propulsion Laboratory
Posted: Wednesday, May 15, 2013

- Seasonal Flows in Palikir Crater

Palikir Crater, which sits inside the much large Newton crater, contains thousands of individual flows called "Recurring Slope Linea", or RSL.

- Polygonal Dunes

Polygons are of great interest because they often indicate the presence of shallow ice or of desiccation such as in a mud flat.

- Dust Devil Tracks and Slope Streaks on Martian Sand Dunes

This observation shows a sand dune field in the Nili Fossae region of Mars. The dark lines swirling over the surface of the dunes are the tracks of dust devils.

-A Possible Landing Site for NASA

HiRISE has become an invaluable tool for other Mars missions to help select landing sites that are safe and scientifically compelling.
