The Curiosity rover is winding between the spectacular Gould mesa and Texoli butte through beautifully layered terrain. The end-of-drive target from last week’s plan was a rock with a knobby/bumpy texture that appears quite different from the typical surrounding bedrock. While this interesting rock was in our workspace today, we ended up being just a touch too close to do contact science. As a result, the science team decided to “bump back” (e.g., drive backwards) to get the rover in an ideal position to analyze and characterize this rock on Wednesday.
In the middle of the rover’s workspace today there was a large patch of soil and sand that MAHLI and APXS teamed up to analyze at a target named “Angeles Crest.” Nearby, Mastcam imaged troughs (depressions) along the axis of the sand ridge to understand how they formed. Mastcam had several other targets in the plan that imaged the workspace and surroundings including “Potrero John,” the knobby rock in the workspace, a rock with similar nodular textures in the distance named “Modjeska Peak,” and a light tan rock with a dome-like structure in the vicinity of “Humber Park.”
ChemCam selected a slab of bedrock and loose (“float”) rock in the workspace to characterize their geochemistry with the LIBS instrument at “Millard Canyon” and “Cajon Pass,” respectively. Off in the distance, the science team selected the face of Gould mesa and upper Texoli butte for ChemCam long distance RMI imaging to get a closer look at the rocks, fractures, and layering.
The environmental theme group scheduled several activities to look at clouds, document the atmospheric opacity, and measure the optical depth of the atmosphere and constrain aerosol scattering properties. We have lots of exciting data in hand and more on the road ahead!
