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).
21 July 2014Integration and functional testing activities for the protoflight models of the BepiColombo Mercury Planetary Orbiter, Mercury Transfer Module, and Magnetospheric Orbiter Sunshield and Interface Structure have now been completed at the Thales Alenia Space facility in Turin, Italy.
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.
12 December 2013The Engineering Qualification Model of the Inertial Sensor Head (ISH) for LISA Pathfinder has passed a significant milestone. The integration of all the components of the ISH with perfect alignment, and the successful completion of qualification tests mark the first time that a heavy test mass inertial sensor has been assembled and successfully...
19 August 2013Tests are being carried out under a technology development programme for planetary penetrators to assess the feasibility of delivering instrument packages to the subsurface of a planet or icy satellite at high speed.
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.
24 June 2013A team of scientists from the University of Glasgow has successfully delivered a significant milestone for LISA Pathfinder - the flight optical bench. Following formal delivery to Astrium GmbH, on 21 June, the optical bench is ready for integration onto the LISA Technology Package (LTP).
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.
#12: BepiColombo Mercury Planetary Orbiter Proto-Flight Mechanical and Propulsion Bus undergoes bake-out
5 February 2013The BepiColombo MPO has been baked out in the Phenix thermal vacuum facility at ESTEC, in Noordwijk, the Netherlands.
#11: BepiColombo Mercury Planetary Orbiter Proto-Flight Mechanical and Propulsion Bus Arrives at ESTEC
18 January 2013The BepiColombo MPO Mechanical and Propulsion Bus Proto-Flight Model has arrived at ESTEC for its bake-out operation.
17 December 2012The mass properties of the BepiColombo Mercury Transfer Module Structural and Thermal Model have been measured at the ESTEC test facilities.
