Status Report From: Jet Propulsion Laboratory
Posted: Thursday, April 24, 2014

- Two-Color Dunes in Meridiani Terra

Why are these dunes different colors? Sand on Mars is typically dark in tone, as it commonly derived from volcanic rocks like lava flows.

- Slumping Terraces on a Crater Wall

This slumped terrace, a result of the crater formation process, gives the crater a concentric ringed appearance.

- A Heart in Ascraeus Mons

What is this strange-looking feature? HiRISE scientists first noticed it in images from the Context Camera and acquired this picture to investigate more closely.

- Opportunity Rover's Winter Work at Murray Ridge

This new image of Opportunity was acquired as a "ride-along" with the CRISM instrument also onboard MRO, to help give better details of the topography here.
