CHEOPS children drawings engraved

Our campaign to collect CHEOPS children drawings is completing a major milestone as the first plaques have been engraved. The article tells the story of their production and illustrates the beautiful results. First CHEOPS Plaque with engraved children's drawings Between March and October 2015, children between the age of 8 and 14 were [...]

Successful vibration test runs

During ten days in August 2017, the CHEOPS telescope had to withstand various tests on the shaker at the University of Bern simulating the conditions during the launch with a Soyuz rocket. The experiments were successful – a big step towards the completion of the flight model. Engineers Daniel Schaedeli and Martin-Diego Busch transport [...]

Preparing the CHEOPS spacecraft platform and simulating mission operations

In our previous update, we reported on the delivery of the CHEOPS telescope from Florence to Bern. While the scientific payload is being assembled in Switzerland, work in Spain has focused on preparing the spacecraft platform that will carry the payload and provide power, propulsion, communications, and thermal control.

Assembling the flight model

After the engineers at the University of Bern integrated and tested models of the CHEOPS space telescope, they are now working on the hardware that will actually be sent into space. In the clean room especially built for CHEOPS they are assembling the flight model of the instrument. http://www.youtube.com/embed/X4ba2M_YtVc «We are proceeding well,» says [...]

Telescope mirror safely delivered to Bern

At the end of April 2017, an eagerly-awaited cargo from Italy arrived at the University of Bern: the telescope flight model of CHEOPS. The incoming inspection carried out on 3 May 2017 showed that the entire hardware had arrived intact. Checking the CHEOPS telescope tube with its 32-cm primary mirror after the journey from [...]

CHEOPS will ride on a Soyuz rocket

Cheops will be launched on a Soyuz from Europe’s Spaceport in Kourou, French Guiana. The image shows the first Soyuz launch from Kourou, in 2011. (Credit: ESA/CNES/ARIANESPACE/Optique Video Du CSG) Now it is clear: the space telescope CHEOPS - CHaracterising ExOPlanet Satellite - will be launched with a Soyuz rocket from Europe’s spaceport [...]

How to build a space telescope

In the next months, engineers at the University of Bern will assemble the CHEOPS space telescope integrating parts arriving from all over Europe. CHEOPS, the CHaracterising ExOPlanet Satellite, is dedicated to study planets orbiting stars outside of our Solar System. Before building the flight model, the team used a structural model for testing which had [...]

Ready for testing electromagnetic compatibility

At the University of Bern, the CHEOPS team integrated all electrical and electronic parts into a model of the space telescope to test whether the different units and wires operate correctly and don’t interfere with each other. The electromagnetic compatibility test will take place in the second half of February in a special chamber at [...]

CHEOPS solar arrays tested and built

Over the last 10 months, the CHEOPS solar cell assemblies have been put through their paces in the test facilities at industry and in the Solar Generator Laboratory of the Power Systems Division (TEC-EP) at the European Space Research and Technology Centre (ESTEC) as part of the qualification campaign. In parallel, the flight solar arrays [...]

Planetarium show about exoplanets

From the beginning of December the topic of exoplanets will inspire the audience of the planetarium of the Swiss Museum of Transport in Lucerne. The new show titled "Out There" was written by the curator Marc Horat and was developed in close collaboration with the NCCR PlanetS. Recently, Marc Horat visited the University of Bern [...]
