CHEOPS fairing sticker winning design

This colourful design capturing the scientific essence of ESA's upcoming CHEOPS exoplanet mission – characterising planets as they transit in front of their host star – has been selected as the winning design that will be featured on the rocket that will launch the satellite into space.

The design was one of over 300 submitted to the competition that offered graphic designers and artists the unique opportunity to feature their work on the rocket that will launch CHEOPS – the CHaracterising ExOplanets Satellite – to Earth orbit.

The design was created by Denis Vrenko of Celje, Slovenia, a 25 year-old graphic designer and final-year architecture student at the University of Ljubljana.

#11: PUTTING THINGS TOGETHER: THE CHEOPS SCIENCE INSTRUMENT ARRIVES IN MADRID

03 May 2018 14:00

Members of the CHEOPS consortium could be proud of their achievement as the science instrument of the upcoming exoplanet mission left Bern on its journey to Madrid last month.

The science instrument and its tailor-made handling equipment left Switzerland by truck in six containers, designed to provide protection from shock, moisture and dust, on 10 April 2018. Its safe arrival in Spain the following day marked a key milestone for the CHEOPS project and enabled Airbus Defence and Space Spain, the prime contractor that has designed the spacecraft, to integrate the science instrument and the spacecraft platform and begin test activities.

N° 9–2018: CALL FOR MEDIA: MEET EUROPE’S EXOPLANET SATELLITE CHEOPS

13 May 2018

Media are invited to join experts of the Characterising Exoplanets Satellite, Cheops, at Airbus Defence and Space in Madrid, Spain, for a unique opportunity to visit the spacecraft in the clean room on 22 May.

Cheops will make observations of exoplanet-hosting stars to measure small changes in their brightness due to the transit of a planet across the star disc. The information will help to reveal the size of planets circling other stars, especially those in the Earth-to-Neptune mass range – a first step to characterising planets outside our Solar System.

The science instrument that will make these measurements recently arrived at Airbus in Madrid, following testing at the University of Bern in Switzerland, for integration with the spacecraft platform. This includes being combined with the solar panels, thrusters, radio transmitters and reaction wheels needed for power, propulsion, communications and attitude control, respectively.

The completed satellite is currently undergoing essential tests and checks at Airbus as part of launch preparations. It will only be there for a few weeks before moving on for final thermal, vibration and acoustic testing in various locations across Europe. Final checks will be conducted when it returns in October, and then it will be packed and prepared for shipment to Europe’s Spaceport in Kourou, French Guiana.

Cheops, which is implemented as a partnership between ESA and Switzerland, is on track to be ready for launch by the end of the year.

This event offers one of the first – and last – opportunities for media to view the complete satellite before its launch.

About the European Space Agency

The European Space Agency (ESA) provides Europe’s gateway to space.

ESA is an intergovernmental organisation, created in 1975, with the mission to shape the development of Europe’s space capability and ensure that investment in space delivers benefits to the citizens of Europe and the world.

ESA has 22 Member States: Austria, Belgium, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Luxembourg, the Netherlands, Norway, Poland, Portugal, Romania, Spain, Sweden, Switzerland and the United Kingdom. Slovenia is an Associate Member.

ESA has established formal cooperation with six Member States of the EU. Canada takes part in some ESA programmes under a Cooperation Agreement.

By coordinating the financial and intellectual resources of its members, ESA can undertake programmes and activities far beyond the scope of any single European country. It is working in particular with the EU on implementing the Galileo and Copernicus programmes as well as with Eumetsat for the development of meteorological missions.

ESA develops the launchers, spacecraft and ground facilities needed to keep Europe at the forefront of global space activities.

Today, it develops and launches satellites for Earth observation, navigation, telecommunications and astronomy, sends probes to the far reaches of the Solar System and cooperates in the human exploration of space. ESA also has a strong applications programme developing services in Earth observation, navigation and telecommunications.

The integrated CHEOP satellite

The integrated CHEOPS satellite in the cleanroom of Airbus Defence and Space Spain in Madrid, before the installation of the solar arrays.

The spacecraft will be shipped in July to Airbus EVT in Toulouse, France, to undergo thermal tests. It will then travel on to RUAG in Zurich, Switzerland, for vibration tests, and further to ESA's technical centre in The Netherlands, for acoustic and electromagnetic compatibility tests. Finally, it will come back to Airbus Defence and Space Spain in Madrid, where the last system validation test will be performed to check readiness for the launch and early operations phase of the mission.

Cheops plaques

Two titanium plaques etched with thousands of miniaturised drawings made by children have been fixed to the CHaracterizing ExOPlanets Satellite, Cheops. Each plaque measures nearly 18 cm across and 24 cm high.

The plaques, prepared by a team at the Bern University of Applied Sciences in Burgdorf, Switzerland, were unveiled in a dedicated ceremony at RUAG on 27 August 2018.

#13: CHEOPS – CHILLED AND CHECKED, SHAKEN AND NOT STIRRED

31 August 2018 10:00

This summer, the CHEOPS satellite breezed through thermal tests in France and vibration tests in Switzerland, demonstrating that it is ready to operate in the extreme cold of space and also fit to withstand the mechanical stresses of launch.

Cheops inside LEAF chamber

ESA’s exoplanet-surveying Cheops satellite, with its distinctive main telescope instrument, seen being prepared for testing within ESA’s Large European Acoustic Facility (LEAF) at the Agency’s ESTEC Test Centre in Noordwijk, the Netherlands this month.

LEAF can subject satellites to the same volume of noise a launcher produces as it takes off and flies through the atmosphere. One wall of the chamber – which stands 11 m wide by 9 m deep and 16.4 m high – incorporates a set of enormous sound horns. Nitrogen shot through the horns can produce a range of noise up to more than 154 decibels, like standing close to multiple jets taking off.

ESA’s Cheops satellite will measure the sizes of known exoplanets by detecting tiny fluctuations in the light of their parent stars. Cheops, or ‘CHaracterising ExOPlanet Satellite’, combines a state-of-the-art scientific performance with a compact design – 1.5 m by 1.4 m by 1.5 m in size, it weighs in at about 300 kg fully fuelled – allowing it to be flown as a secondary passenger on a Soyuz launcher inside its ASAP-S adapter.
 
A test version of Cheops – its ‘structural qualification model’ plus ‘instrument structural and thermal model’ – underwent previous LEAF testing back in November 2015. Once its acoustic testing was complete this final Cheops ‘flight model’ went on to electromagnetic compatibility testing in ESA’s Maxwell facility.

Once its test campaign is complete, the satellite is scheduled for launch readiness at Europe’s Spaceport in French Guiana early next year.
