The ExoMars Trace Gas Orbiter’s neutron detector FREND was switched on between 24 February and 2 March, and 5–7 March 2017 and collected data during eight orbits of the planet, with three of its detectors. The data complement those obtained during the first test campaign, and will be used to estimate the spacecraft internal background radiation and the level of neutron signal from Mars.
