CHEOPS is being prepared for launch

CHEOPS is being prepared for launch Today’s Video of the Day from the European Space Agency describes the CHaracterising ExOPlanet Satellite (CHEOPS) mission, which is aimed at measuring many of the known exoplanets with ultrahigh precision. 

CHEOPS data will be combined with existing data to determine the density of these planets and to provide some indication of their structure and composition.

Exoplanets range from rocky and hot to gassy, and the scientists are particularly interested in those planets that are in the super-Earth to Neptune size range. CHEOPS is a European space telescope. Its objective is to determine the size of known extrasolar planets, which will allow the estimation of their mass, density, composition. 

Scientists at the Geneva Observatory in Switzerland will be processing the data from CHEOPS, which is being prepared for launch later this year. CHEOPS(CHaracterising ExOPlanets Satellite) is a European space telescopeto determine the size of known extrasolar planets, which will allow the estimation of their mass, density, composition and their formation. Launched on 18 December 2019, it is the first Small-class mission in ESA’s Cosmic Visionscience programme. CHEOPS launched on board of a Soyuz-Fregat rocket on December 18, 2019. 

The bus of the CHEOPS spacecraft is based on the SEOSAT platform. A sunshield mounted on the platform protects the radiator and detector housing against the Sun, and it also features solar panels for the electrical power subsystem. CHEOPS measures photometric signals with a precision limited by stellar photon noise of 150 ppm /min for a 9th magnitude star. mission in ESA’s science programme, and the first of three dedicated exoplanet missions being prepared by ESA.  CHEOPS is being prepared for launch as seen above in video showing the launch and explaining the mission.
