ESA - CHEOPS updates
« on: 09/24/2013 08:38 PM »
CHEOPS - CHaracterizing ExOPlanet Satellite

CHEOPS - CHaracterizing ExOPlanet Satellite - will be the first mission dedicated to searching for exoplanetary transits by performing ultrahigh precision photometry on bright stars already known to host planets. It will provide the unique capability of determining accurate radii for a subset of those planets, in the super-Earth to Neptune mass range, for which the mass has already been estimated using ground-based spectroscopic surveys. CHEOPS will also provide precision radii for new planets of Neptune-size and smaller that are discovered by the next generation of ground-based transit surveys.

On 19 October 2012 CHEOPS was selected for study as the first S-class mission in Cosmic Vision 2015-2025. Formal adoption of the mission is expected in late 2013, with launch planned for 2017.

ESA selects SSTL to design Exoplanet misión

11 Sep 2013

Surrey Satellite Technology Ltd (SSTL) has been selected by the European Space Agency (ESA) for the competitive design phase of CHEOPS - a satellite that will improve mankind’s understanding of exoplanets (planets orbiting distant stars outside our solar system). The contractor selection for the implementation phase is planned by mid-2014 and the launch is scheduled late 2017.

CHEOPS exoplanet mission meets key milestones en route to 2017 launch

11 July 2014

http://sci.esa.int/cheops/54321-cheops-exoplanet-mission-meets-key-milestones-en-route-to-2017-launch/

Quote
ESA’s first small Science Programme mission is ready for construction. The implementation phase has started, meaning that the spacecraft has gone from selection to implementation in less than 18 months.

Quote
CHEOPS was selected by ESA in October 2012 from 26 proposals that were submitted in response to the announcement of the small mission programme. It was officially adopted into the Science Programme in February this year. Capped to an ESA cost of €50 million, it is being developed in collaboration with the Swiss Space Office (SSO), a division of the Swiss State Secretariat for Education, Research and Innovation (SERI), and the University of Bern, Switzerland. The Swiss organisations lead the consortium of 11 ESA Member States contributing to the mission and represented in the CHEOPS Science Team. The spacecraft will be built by Airbus Defence and Space, Spain.

Quote
CHEOPS will most likely be launched as a passenger on a Soyuz or Vega launcher from Kourou at the end of 2017.

#1: CHEOPS spacecraft hardware delivery

http://sci.esa.int/cheops/56102-1-cheops-spacecraft-hardware-delivery/

Quote
CHEOPS is now moving steadily from a paper design to the hardware phase. Over the last couple of months the Instrument Consortium, led by the University of Bern, has taken delivery of the first hardware from Airbus Defence and Space (ADS)–Spain, the prime contractor for the CHEOPS platform. These deliveries included the Platform Simulator, as well as the platform panels for instrument assembly and handling, the Star Tracker Optical Head Assemblies with their associated multi-layer insulation (MLI), and the support structure for the Baffle Cover Assembly.

Cheops entering acoustic chamber
 
A test model of ESA’s exoplanet-watching Cheops satellite being placed in an acoustic chamber in Europe’s largest spacecraft testing centre, helping to ensure the flight version can endure the extreme conditions of a rocket launch.
 
The Characterising ExOPlanet Satellite is ESA’s first small science mission. Selected in October 2012, it will track the crossings of known planets across the face of their parent stars, to make detailed deductions of their size and composition. The telescope will detect tiny shifts in stellar brightness with ultra-high precision.
 
Once the tests are completed, this ‘structural qualification model’ will be reconfigured as the actual satellite, helping to meet a tight development schedule that is aiming for launch readiness at the end of 2017 and a shared launch opportunity in the first half of 2018.
 
Cheops is seen here being moved into ESA’s Large European Acoustic Facility, capable of subjecting satellites to the same noise as a rocket produces as it takes off and flies through the atmosphere.
 
The chamber is an integral part of ESA’s ESTEC test centre in Noordwijk, the Netherlands, a collection of spaceflight simulation facilities under a single roof.
 
One wall of the chamber is embedded with 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.

#6: CHEOPS SOLAR ARRAYS TESTED AND BUILT

16 December 2016 11:26

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 have been manufactured and delivered.

#8: PREPARING THE CHEOPS SPACECRAFT PLATFORM AND SIMULATING MISSION OPERATIONS

12 July 2017 11:54

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.

Launch your design with Cheops

2 November 2017

ESA is offering graphic designers and artists a unique opportunity to feature their work on the rocket carrying the Cheops satellite.

The design will be placed on the Soyuz rocket’s fairing, the tough outer shell that protects the satellite during launch and as it passes through the atmosphere into space.

#10: IT'S GETTING REAL: TESTING FLIGHT HARDWARE WITH MISSION CONTROL CODE

18 December 2017 10:08

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.

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.
