CHEOPS launch slot announced

The CHaracterising ExOPlanet Satellite, CHEOPS, will target 15 October to 14 November 2019 for launch as the European Space Agency ESA announced on 23 November 2018. CHEOPS will lift off on a Soyuz rocket operated by Arianespace from Europe’s spaceport in Kourou, sharing the ride into space with a satellite that is part of the [...]

Verbunden mit dem All

Nach einer langen Europa-Tour ist der CHEOPS-Satellit nach Madrid zu Airbus Defence and Space zurückgekehrt. Auf seiner Reise musste er verschiedene Prüfungen bestehen: thermische Tests im Vakuum bei Airbus in Toulouse, mechanische Vibrationstests bei RUAG Space in Zürich sowie Akustik- und elektromagnetische Verträglichkeits-Tests im ESA-Technikzentrum in den Niederlanden. "Alle Tests wurden ohne grössere Zwischenfälle abgeschlossen", [...]

CHEOPS – withstanding the sound of launch and avoiding radio interference

For the CHEOPS mission, September was a busy month of acoustic noise testing and Electromagnetic Compatibility (EMC) testing at ESA's technical centre in the Netherlands. The successful tests have shown that the satellite can withstand the high sound pressures of launch and is compatible with its electromagnetic environment at launch and in orbit.

The Cheops spacecraft in the LEAF test chamber

The Cheops (CHaracterising ExOPlanet) spacecraft in the Large European Acoustic Facility (LEAF) test chamber at ESA's European Space Research and Technology Centre (ESTEC) in Noordwijk, the Netherlands, on 7 September, 2018. The Cheops spacecraft has undergone acoustic testing earlier this month. Cheops will observe bright stars known to host exoplanets, in particular Earth-to-Neptune-sized planets, anywhere [...]
