Figure showing the observations being made by the ExoMars Trace Gas Orbiter during the 7–8 March orbit of the Red Planet. The neutron detector FREND collects data during the entire period. The Atmospheric Chemistry Suite (ACS), the Colour and Stereo Surface Imaging System (CaSSIS), and the Nadir and Occultation for Mars Discovery (NOMAD) have the opportunity to collect data along the portions of the orbits indicated.
The current 24 hour orbit takes the Trace Gas Orbiter from 37 150 km at its farthest and to within about 200 km of the planet’s surface at its closest approach.
