ESA’s Characterising Exoplanet Satellite, Cheops, inside the transport module during transfer to the final integration building on 29 November at Europe’s Spaceport in Kourou, French Guiana.
Cheops is ESA’s first mission dedicated to the study of extrasolar planets, or exoplanets. It will observe bright stars that are already known to host planets, measuring minuscule brightness changes due to the planet’s transit across the star’s disc.
