Light-Toned Material in East Coprates Chasma
HiRISE PICTURE OF THE DAY: 6 DECEMBER 2022

Exploring Coprates Chasma

Light toned material has been observed by the Context Camera and potentially reflects low-calcium pyroxene that indicates pristine crustal material exposed in this location. This is an area of interest for a potential future rotorcraft mission traverse (Mars Science Helicopter) that would explore this and other terrains in situ.



Ridges in Cydonia Mensae
The ridge is made of material more resistant to erosion and, considering the craters on its flanks, was formed long ago.

Boundary Condition Controls on the High-Sand-Flux Regions of Mars
It is often unclear where and why sediment is mobile on today’s Mars. A new paper takes a deeper look.
