CHEOPS in the clean room

CHEOPS in the clean room

The copper-coloured baffle cover of our Characterising Exoplanet Satellite, CHEOPS, in the clean room at Airbus Defence and Space Spain, Madrid.

After completing spacecraft testing, the satellite has passed a very important review that determined it is ready to fly. CHEOPS will be stored in Madrid for a few months before being shipped to the launch site in Kourou, French Guiana; launch is scheduled in the time slot between 15 October and 14 November.

The baffle cover pictured in this image is designed to protect the satellite's scientific instrument – a powerful camera, or photometer – during assembly and launch. Once in space, the cover will open, allowing light from stars to enter the telescope.

CHEOPS will make observations of exoplanet-hosting stars to measure small changes in their brightness due to the transit of a planet across the star's disc, targeting in particular stars hosting planets in the Earth-to-Neptune size range. The information will enable precise measurements of the sizes of the orbiting planets to be made: combined with measurements of the planet masses, this will provide an estimate of their mean density – a first step to characterising planets outside our Solar System. 

CHEOPS paves the way for the next generation of ESA's exoplanet satellites, with two further missions – PLATO and ARIEL – planned for the next decade to tackle different aspects of the evolving field of exoplanet science.
