Curiosity is currently preparing to bump to her next drill site in the Pettegrove Point member, but not before gathering many observations at our current location. There are interesting color variations in today's workspace, with grey, tan, and red gradients across the outcrop that can be seen in the above image. Curiosity will document these color variations in detail with images from Mastcam and the Mars Hand Lens Imager (MAHLI) and chemical measurements from the ChemCam and Alpha Particle X-Ray Spectrometer (APXS) instruments. This is a lot of data to relay, but we expect downlinks from both the Mars Odyssey and the ExoMars Trace Gas Orbiter spacecrafts over the weekend.
On Sol 2131, the geology theme group planned ChemCam measurements of the targets "Shiant Isles" and "Inchnadamph," which are grey-toned rocks. The observation on Inchnadamph is especially interesting because ChemCam will shoot two sets of 150 laser shots into the rock to see if there are chemical variations with depth. The APXS instrument will also make chemical measurements on a darker grey target "Mount Battock" and a lighter grey target "Scourie More," in addition to a red target "Dobbs Linn" which will be brushed beforehand with the Dust Removal Tool (DRT). All of these targets will be documented with high-resolution Mastcam and MAHLI images.
On Sol 2132, Curiosity will acquire a Mastcam multispectral observation of all these targets to enable a detailed assessment of these color variations. Mastcam will also image the "Bullers of Buchan" target, which is an outcrop that may expose layering and nodules. Curiosity will then drive a few meters to our drill site.
Sol 2133 is packed with three science blocks filled with activities from the environmental theme group: Mastcam tau and crater rim extinction observations, Navcam zenith, suprahorizon, and dust devil movies, and Navcam line of sight observations. Curiosity will also make ChemCam passive measurements and an APXS atmospheric measurement. All of these observations will help with our ongoing monitoring of the atmosphere as the dust storm settles. After all of this, we look forward to seeing our drill workspace on Monday!

Tools on the Curiosity Rover
The Curiosity rover has tools to study clues about past and present environmental conditions on Mars, including whether conditions have ever been favorable for microbial life. The rover carries:
Today was a very busy planning day for the Curiosity operations team. We planned a 3-sol plan, with contact science, imaging, environmental monitoring and a drive.
Similar to its namesake in Scotland, the Glen Torridon area on Mars affords us stunning vistas, but in our case, of the relatively low-lying clay bearing (from orbit) unit flanked to the north by the higher ground of the Vera Rubin Ridge and to the south, by Mount Sharp.
The accompanying image shows the target "Brent" in the lower right corner; it was analyzed with ChemCam and APXS, and imaged with MAHLI over the weekend.
Curiosity successfully completed her drive yesterday and is currently parked on top of one of the ridges ("Knockfarril Hill") in the clay-bearing unit.
This weekend's plan started off on Sol 2301 with some Mastcam atmospheric observations, followed by ChemCam analysis of "Loch Ness" and "Loch Skeen," examples of brown and gray bedrock.
Curiosity is continuing the first phase of its journey to the "clay-bearing unit," the low elevation portion in the middle distance of this Navcam image with a series of "touch-and-go" driving sols.
Curiosity has moved for the first time since December 13, 2018. More importantly, Curiosity is moving to a new geological unit that we have so far called the "Clay-Bearing Unit".
Sometimes the best laid plans of rovers go astray. After wrapping up at the Rock Hall drill site yesterday, the plan was for Curiosity to start driving towards the clay-bearing unit, starting with a series of small bumps so that MAHLI could take images of the full outer circumference of the wheels.
Today was our last day at "Rock Hall," so it was our final chance to get every last bit of science at this location. We had a 2.5 hour science block filled with Mastcam change detection imaging of the Rock Hall drill fines and alternating ChemCam RMI and LIBS observations of the Rock Hall dump pile, drill tailings, and target "St.Cyrus 2."
Today we planned a single sol of activities, Sol 2291. As we begin to wrap up our activities at the Rock Hall drill site, Sol 2291 is chock full of science observations. We'll begin the sol with an hour-long science block.
We will soon be leaving the Rock Hall area, thus this one last look at the drill site from a hazard camera perspective. Seeing those holes always is special, even for #19!
Our onboard instruments SAM (Sample Analysis at Mars) and CheMin (Chemistry and Mineralogy) have come to the end of their investigation of the Rock Hall target, likely to be our last drill location on the Vera Rubin Ridge, so this 2-sol plan is the beginning of the drill operation wrap up.
Today was a very smooth planning day on Mars, with the first scheduled science block in the plan being entirely filled by various spectroscopic ChemCam observations. The ChemCam instrument has the capabilities to be used in both passive and active modes, both of which were included in today's plan.
Today we are continuing the drill campaign at our red Jura target "Rock Hall." The focus of this weekend's plan is the dropoff of the Rock Hall sample to the SAM instrument, which will occur on Sol 2281.
The holiday planning completed successfully and included 10 sols of five-hour-long morning meteorological observations by REMS, during the period when more complex activities were precluded.
