Sols 1980: Back to science

Posted by Ryan Anderson

Today, Sol 1980, we’re taking a break from drilling activities to continue with our remote science campaign at our current location. We have three science blocks in today’s plan, which we’ve filled to the brim with a variety of observations. In the early afternoon, we’ll use Mastcam to make a multispectral observation on ‘Lake Orcadie 2,’ the location of our second intended drill target (which is just to the right of Lake Orcadie, pictured in the Navcam image above). We’ll then take a Navcam movie to look for dust devils. Next up is a series of ChemCam LIBS observations to target Lake Orcadie 2, ‘Black Cuillin,’ and ‘St Kilda.’ Black Cuillin and St Kilda are repeat observations to take a closer look at small-scale features in our workspace. All ChemCam targets will also be documented with Mastcam images. We’ll take an additional Mastcam mosaic of the ‘Dunbar’ target to better characterize the stratigraphic stacking of rocks around the rover.

Later in the afternoon we have another science block, during which we’ll use ChemCam to take a series of long-distance images of the Peace Vallis fan. After that, we’ll take a set of Navcam movies to help us measure the velocity and height of clouds above us.

Our final science block will be first thing in the morning on Sol 1981, which we’ll use to carry out some standard ENV observations, including a Mastcam tau, crater rim extinction, and a few Navcam movies.
