Barchan Pac-Man

Here is something interesting: a barchan dune filling the upwind portion of a small impact crater in a Pac-Man-like shape. This “dune-in-a-crater” is nearly at the highest extent of the field. It’s also probably a rare configuration, and over the next few tens of thousands of years the sand will be blown out of the crater. Enjoy it while it lasts!

HiRISE 10K: Lava Flows in Daedalia Planum

To the southwest of Arsia Mons in Daedalia Planum, wide lava flow units emanating from the volcano coalesce to form a vast volcanic plain.

A Layered Mound in Claritas Rupes

Also available in Context Camera data, the objective of this observation is to examine a layered mound near a curved valley. Claritas Rupes is a 924-kilometer long scarp to the southwest of Solis Planum, and part of the Claritas Fossae unit. The term “rupes” is used in planetary geology to refer to escarpments and is the Latin word for “cliffs.”

HiRISE 8K: Layers Exposed in the Walls of an Impact Crater

Partway down from the crater rim is a prominent bright layer of bedrock. These layers must correspond to different types of rock that were deposited as nearly flat-lying sheets.
