Abstract
The Colour and Stereo Surface Imaging System (CaSSIS) is the main camera on board the ExoMars Trace Gas Orbiter (TGO). Following launch of TGO on 14 March 2016, CaSSIS began nominal science operations in April 2018. At the time of writing CaSSIS has acquired an average of 21 observations per day, totaling 20.5 Tbits of downlinked telemetry, and has observed approximately 6% of the Martian surface.
