We acquired this image to obtain more data points needed for a comparison of activity pre- and post a planet encircling dust event that occurred in 2018. We imaged Russell Crater many times before to track changes of gully activity that we see on the extensive dunes here. Russell Crater is located in Noachis Terra, with some of the oldest terrain on Mars.
