On the preceding sol, the rover completed its third round of using vibration of scooped Martian soil to scrub the interior surfaces of the sample-processing mechanisms on the rover's arm. Also on Sol 81, the rover's Sample Analysis at Mars (SAM) instrument completed an analysis of a sample of Martian atmosphere.
The rover continues regular monitoring of the surrounding environment using the other instruments of its science payload.
