Two titanium plaques etched with thousands of miniaturised drawings made by children have been fixed to the CHaracterizing ExOPlanets Satellite, Cheops. Each plaque measures nearly 18 cm across and 24 cm high.
The plaques, prepared by a team at the Bern University of Applied Sciences in Burgdorf, Switzerland, were unveiled in a dedicated ceremony at RUAG on 27 August 2018.
