The ExoMars Trace Gas Orbiter is now at Mars, preparing its orbit for science operations late next year. On board is a wonderful camera called the Colour and Stereo Surface Imaging System (CaSSIS) that will take amazing 3D images of the surface as the TGO hunts down methane sources. Nicolas Thomas of the University of Bern, Principal Investigator for the instrument, tells us how it all works and what we can expect from this fascinating device.

The ExoMars Trace Gas Orbiter's primary mission is to hunt down sources of trace gasses in the orbiter and characterize them. Chief among these chemicals is Methane, and when it is isolated on the surface, we're going to want to know what that place looks like. Enter the Colour and Stereo Surface Imagine System, a state of the art instrument that can take stereo images of the surface, allowing us to see Mars in 3D. Nicolas Thomas, Principal Investigator of the instrument, joins us to tell us all about this fascinating device, including its operations, how it targets science and why finding methane is so important.
