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.

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 [...]

Test of the CHEOPS CCD

This interactive page describes the different elements of the optical bench to test and calibrate the entire optics of the CHEOPS space telescope including the CCD detector. The photo was taken in the clean room of the Physics Institute of the University of Bern and the diagram shows the optical path of the installation. To [...]

Steady progress for CHEOPS

The CHEOPS mission continues to make steady progress with a number of milestones being successfully met. In the past few months these have included the completion of the System Critical Design Review, the first EMC testing of the instrument, and the first release of the mission operations system.

Swiss government visits CHEOPS

All seven members of the Swiss Federal Council paid the Center for Space and Habitability of the University of Bern a visit. They were informed about the important role the university plays in space projects such as CHEOPS. To kick off its annual “school trip” on July 7th, 2016, the Swiss Federal Council visited the [...]

The Universe from a Child’s Perspective

“The Universe provides ample scope to use one’s own imagination,” says Anna Lehninger.   The art historian investigates children’s drawings as a cultural asset and has had a look at the pictures resulting from the drawing campaign carried out in association with the CHEOPS mission. In early 2018, 3000 drawings will be sent with the CHEOPS [...]
