It’s getting real: testing flight hardware with mission control code

With the flight models of the CHEOPS spacecraft and telescope maturing, crucial tests can now be run with real hardware in place of simulations. The latest such tests involved operating the payload with the Mission Control System to test and validate real operational command sequences.

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 [...]
