An Arianespace Soyuz rocket will carry the first COSMO-SkyMed Second Generation (CSG 1) radar surveillance satellite for ASI, the Italian space agency. The European Space Agency’s Characterizing Exoplanet Satellite, or CHEOPS, will fly as a secondary payload on the mission. Built by Airbus Defense and Space in Spain with a Swiss-developed science instrument, CHEOPS will observe transits of planets around other stars to measure their radii.
