Curiosity Blog | Sols 3044-3046: Lots of dark sand

The Sol 3044 drive brought MSL to an area (pictured below) mostly covered by dark sand, with very few exposed rocks in the arm workspace.  So, one of the first things I did this morning as MAHLI/MARDI uplink lead was to search for good locations for contact science.

Airborne dust plumes lofted by dislodged ice blocks at Russell Crater, Mars

Linear dune gullies on poleward‐facing Martian slopes are enigmatic. Formation by CO2‐ice block or snow cornice falls has been proposed based on optical imagery of bright, high‐albedo features inside gully channels. Because these features often resemble patchy frost residue rather than three‐dimensional blocks, more evidence is needed to support...

Exposure of an early to middle Noachian valley network in three dimensions on Mars

We document a set of channels in a section of the Martian cratered highlands located between crustal massifs northeast of Hellas Planitia that are visible in cross section and planview >200 m below the surface. The morphometry and spatial distribution of the outcrops provide concrete geological evidence of a dynamic aqueous system in a...

Geologic map of Jezero crater and the Nili Planum region, Mars

The cratered highlands located northwest of Isidis Planitia have been recognized as one of the best preserved Noachian landscapes currently exposed on Mars; the area hosts a record of diverse surface processes, diagenesis, and aqueous alteration. This region has consistently been considered a high priority for landed-mission exploration and...
