#09: JWST instruments are coming in from the cold
2 February 2016After being tested at extremely low temperatures for more than two months, the four instruments of the James Webb Space Telescope are preparing to come in from the cold.
#3: Simulated sound of launch for CHEOPS
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.
#2: CHEOPS prepares for first spacecraft test campaign
28 September 2015CHEOPS is progressing steadily through the hardware manufacturing and related testing phase.
#1: CHEOPS spacecraft hardware delivery
1 July 2015This is the first entry in the CHEOPS Journal, a series of articles documenting milestones in the first small (S-class) mission of ESA's Science Programme.
#08: New detectors and microshutters for NIRSpec
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...
#07: Summer 2014 - first combined test of all four instruments
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).
#06: NIRSpec dances into place
4 April 2014An important milestone for the James Webb Space Telescope (JWST) was passed on 25 March with the installation of the Near InfraRed Spectrograph (NIRSpec) on the Integrated Science Instrument Module (ISIM) at NASA's Goddard Space Flight Centre.
#05: NIRSpec prepared for integration in ISIM
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.
#04: MIRI keeps cool under low pressure
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.
#03: NIRSpec arrives at NASA Goddard
30 September 2013The Near-Infrared Spectrograph (NIRSpec), contributed by ESA to the James Webb Space Telescope (JWST), has arrived at NASA's Goddard Space Flight Center.
#02: NIRSpec's European adventure
7 August 2013In this second entry of the JWST MIRI and NIRSpec integration and test journal, we catch up with NIRSpec - the Near InfraRed Spectrograph, before it departs Europe for NASA's Goddard Space Flight Center (GSFC).
#01: MIRI integrated into the James Webb Space Telescope (JWST)
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.
#12: Gaia Flight Model Testing Completed
25 June 2013The final test campaigns for the Gaia Flight Model spacecraft have been completed, paving the way for shipment to the launch site.
#11: Gaia Flight Model Mass Properties Testing
17 June 2013The Gaia Spacecraft Flight Model has successfully completed its mass properties test campaign.
#10: Gaia Electromagnetic Compatibility Testing
31 May 2013The Gaia Spacecraft Flight Model has successfully completed the electromagnetic compatibility test campaigns at the facilities of Intespace in Toulouse, France.
#09: Gaia Flight Model Payload Data Handling Unit Delivered and Integrated
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.
#08: Gaia Flight Model Payload Module thermal testing completed
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.
#07: Gaia launcher separation test and Payload Module acceptance vibration tests completed
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.
#06: Gaia Payload Module integration completed
17 September 2012Integration of the Flight Model of the Gaia Payload Module has been completed. It has undergone acceptance vibration testing; thermal balance and thermal vacuum testing will be carried out towards the end of this year.
#05: Gaia Service Module Thermal Balance/Thermal Vacuum testing completed
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.
