NASA’s Curiosity Mars rover is now performing Sol 2634 tasks.

Lucy Thompson, a planetary geologist at Canada’s University of New Brunswick, reports that two recent Mars Reconnaissance Orbiter (MRO) passes that should have downlinked the data from Curiosity’s New Year activities, to enable planning, were delayed during processing on the ground.

“We did not get the images of our workspace until just prior to when we were supposed to deliver our plan,” Thompson added. The Tactical Uplink Lead for the day gave permission to delay delivery, and the team efficiently managed to add two targeted Chemistry and Camera (ChemCam) analyses of bedrock (“Ben Eighe” and “Braid Hills”), with accompanying Mastcam documentation imaging.

Environmental observations

The rest of the plan was filled with untargeted environmental observations, Thompson explains, including ChemCam passive sky, a Navcam dust devil survey and cloud movie observations, as well as the standard Rover Environmental Monitoring Station (REMS), Dynamic Albedo of Neutrons (DAN) and Radiation Assessment Detector (RAD) activities.

A Sample Analysis at Mars (SAM) Instrument Suite scrubber clean and transfer data were also included, following on from SAM atmospheric measurements over the holiday period.

Thompson reports that a Navcam 3×1 mosaic was planned, which should facilitate targeting with Mastcam and the ChemCam Remote Micro-imager in upcoming plans.

Stunning view

“The planned drive from the previous sol executed flawlessly, resulting in a stunning view of the top of Western Butte, and a workspace strewn with dark angular float rocks (not in place), on top of the paler, in-place bedrock,” Thompson points out.

“The previous workspace had also included intact bedrock with dark, angular float rocks. We received closer up images and compositional data for some of these float rocks over the holidays, revealing some interesting similarities to rocks

encountered a lot earlier in the mission,” Thompson adds.

“The geologists are trying to figure out the relationship of the dark, angular blocks to the in-place bedrock, and intact darker, resistant, capping rock observed at the top of slopes immediately behind Western Butte,” Thompson concludes. “Everyone is excited to be able to continue to investigate the bedrock and float rock at this location, as well as to document the view afforded to Curiosity from this vantage point near the top of Western Butte.”
