A showcase of some of the first and highest resolution images acquired by the Colour and Stereo Surface Imaging System (CaSSIS) on the ExoMars Trace Gas Orbiter on 22 November 2016.
The first image sequence shown was taken at a distance of 5300 km with a resolution of 60 m/pixel, about 44 minutes before closest approach. It illustrates how CaSSIS acquires data by taking images in colour simultaneously: at panchromatic, red, near-infrared and blue wavelengths.
A 3D reconstruction of a small area in Noctis Labyrinthus is also presented, based on a stereo pair of images taken, and presented with an altitude map with a resolution of less than 20 m.
Next, a spectacular high-resolution image sequence acquired during closest approach of 235 km altitude is presented. At this time, the spacecraft was flying over the Hebes Chasma region. The highest resolution data acquired is at 2.8 m/pixel. The flyover is shown at half the speed at which the data were acquired.
Then, an image swath about 25 km wide is shown of Arisa Chasmata, which is located on the flanks of a large volcano on Mars named Arsia Mons.
Finally, a close up of a 1.4 km-diameter crater sitting in the rim of a much larger crater near the Mars equator is presented. This image was acquired at 7.2 m/pixel.
This video was produced by the CaSSIS camera team and the University of Bern.
