11 November 2015The CHEOPS spacecraft continues its fast-track implementation with a whistle-stop tour of test centres in Europe. Having completed acoustic tests at the European Space Research and Technology Centre in Noordwijk, the Netherlands, CHEOPS is on the road again. Next stop: Madrid.
28 September 2015CHEOPS is progressing steadily through the hardware manufacturing and related testing phase.
25 February 2015The past two months have seen a team of engineers engaged in the intricate activity of replacing key components of the Near InfraRed Spectrograph (NIRSpec) on the James Webb Space Telescope. The instrument is now ready for the next series of extensive environmental tests devised to ensure that JWST's instruments can withstand the stresses and...
24 February 2015A major milestone was reached for the James Webb Space Telescope (JWST) in the summer of 2014 when all four instruments, installed on the Integrated Science Instrument Module, completed cryogenic testing at NASA's Goddard Space Flight Center (GSFC).
5 February 2014The Near InfraRed Spectrograph (NIRSpec) on the James Webb Space Telescope (JWST) is being installed on the Integrated Science Instrument Module (ISIM) at Goddard in preparation for an extensive series of tests with the full instrument complement. In addition, new detectors have been selected for NIRSpec, to be installed later this year.
3 February 2014The Mid-Infrared Instrument (MIRI) on JWST has performed beautifully during its first cryo-vacuum test campaign carried out at NASA's Goddard Space Flight Center towards the end of last year. An examination of data recorded during those tests confirms that the instrument is in good health and performing well.
8 July 2013This is the first entry of the JWST MIRI and NIRSpec integration and test journal. This series of articles will provide a behind-the-scenes look at how the Mid-Infrared Instrument (MIRI; provided by a European Consortium) and the Near-Infrared Spectrograph (NIRSpec; provided by ESA), are being prepared for launch and operation in space.
23 May 2013The Gaia Flight Model Payload Data Handling Unit has been delivered and integrated into the Gaia Service Module. Its arrival allowed extensive end-to-end testing of the spacecraft systems to be performed.
20 February 2013Thermal testing of the Gaia flight model payload module was completed at Centre Spatial de Liège. The payload module was then returned to Astrium Toulouse for integration with the service module.
29 October 2012Testing of the separation of the Gaia Service Module from its Launch Vehicle Adapter has been completed, as have the acceptance vibration tests on the Payload Module.
10 September 2012The Protoflight Model of the Gaia Service Module has successfully completed thermal balance and thermal vacuum testing in the SIMLES chamber at Intespace Toulouse.
