Mars: December 2021



This enhanced-color image of Mars' Jezero Crater was taken by the Mastcam-Z instrument aboard NASA's Perseverance rover on April 18, 2021.


Based on a Context Camera image, the rationale for this observation is to get a closer look at this layered butte.


Sometimes, we acquire an image for the simple reason of getting either more coverage of an area, and/or to complete a mosaic of a particular spot.


These lovely linear dunes at Meroe Patera identified in Context Camera images that have developed in a sand starved region of the dune field, elongating from behind a cliff.


The distinctively fluted surface and elongated hills in this image in Medusae Fossae are caused by wind erosion of a soft fine-grained rock.


Earth and Mars were formed from material that largely originated in the inner Solar System; only a few percent of the building blocks of these two planets originated beyond Jupiter's orbit.


Cross Crater, about 65 kilometers in diameter, is located in the highlands of the Terra Sirenum region of Mars.


North of Ganges Chasma lies Orson Welles Crater, whose floor contains broken up blocks we call chaotic terrain and which is the source for the major outflow channel Shalbatana Vallis.


The 17th flight of NASA's Ingenuity Mars Helicopter on Dec. 5 pushed the total flight time past the 30-minute mark.


We've come to understand in recent years that about a third of Mars has ice just below the surface.


Scientists with NASA's Perseverance Mars rover mission have discovered that the bedrock their six-wheeled explorer has been driving on since landing in February likely formed from red-hot magma.


This image shows the edge of the Martian South Polar layered deposit. The stack of fine layering is highlighted by the rays of the polar sun.


This observation show us chaotic terrain in Aromatum Chaos, with collapse features and potential dikes.


Curiosity is preparing to "shoot the gap"and dash through the Maria Gordon notch (the cliff-lined valley seen in the image above) in the sols ahead.


Context Camera imagery reveals dark streaks extending east of minor crater rims within and around Holmes Crater.
