A thousand days of CHEOPS

The Swiss space telescope CHEOPS will celebrate its 1000th day in orbit around the Earth on Tuesday 13 September. Its excellent condition will allow it to remain active for several more years.

Under these conditions, it could continue to reveal the fascinating details of many exoplanets for many years to come. CHEOPS is a joint mission of the European Space Agency (ESA) and Switzerland, led by the University of Bern (UNIBE) in collaboration with the University of Geneva. Since its launch at the Guiana Space Centre on 18 December 2019, the telescope has demonstrated its functionality and accuracy beyond expectations.
