Inspired by the success of the Hubble Space Telescope, NASA, ESA and the Canadian Space Agency have collaborated since 1996 on the design and construction of a scientifically worthy successor. Due to be launched in 2018, the James Webb Space Telescope is expected to have as profound and far-reaching an impact on astrophysics as did its famous predecessor.
#07: Summer 2014 - first combined test of all four instruments 24 February 2015 A 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).

#05: NIRSpec prepared for integration in ISIM 05 February 2014 The 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. Read more
#04: MIRI keeps cool under low pressure 03 February 2014 The 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. Read more
