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 [...]

Vibration Test at RUAG Space

When CHEOPS will be launched in 2018 it will be subjected to very high vibration loads. The vibration test of the structural model at RUAG Space in Zurich in October 2015 simulated the launch of the satellite into the earth orbit as Willem Coppoolse, Senior Project Manager at RUAG Space explains in the video.

Successful CHEOPS test

The video shows the successful baffle cover opening test performed at Airbus Defence and Space (ADS) – Spain after the spacecraft mechanical environmental campaign. The cover, which is used to protect the telescope against environmental influences during ground operations and launch, opened as planned roughly 50 seconds after the system has been switched on. The [...]
