Whew! It’s going to be a busy weekend on Mars! The Sol 1157 plan starts off with an activity to test out AEGIS, a software tool that will help with choosing targets for ChemCam and Mastcam. The AEGIS activity will take ChemCam images of two targets: “Ashley Lakes” and “Amsden”. That is followed by a ChemCam observation of the target “Augusta”. Mastcam will take supporting images of Ashley Lakes and Amsden, plus an image of “Dodd Ranch” and two mosaics: a 3×2 and a 9×2.

Once the remote sensing is done, the arm will get a workout. MAHLI and Mastcam have some images of the sky to help with calibration, and then MAHLI will take some images of its own calibration target and the APXS calibration target. After that, MAHLI will take some images of the wheels, and then APXS will measure its calibration target. Once that is finished, we will brush the dust off of the target Augusta, take some Mastcam and MAHLI images of it, and then place APXS on it to make some measurements on and off the brushed spot.

On Sol 1158 the rover will drive to a location that looks to be a nice viewpoint, and that will be followed by standard post-drive images, including a 27×2 360 degree panorama with Mastcam. On Sol 1159, Mastcam has a tau observation to measure the amount of dust in the atmosphere, and Navcam has a couple of movies to watch for clouds and dust devils. Later in the day, Mastcam will do another tau, and ChemCam will make a measurement of its titanium calibration target.
