Satellite equipment developed with the help of space engineers and technicians at the University of Leicester is about to receive its first taste of the harsh conditions of space -without even leaving the UK.
The sophisticated instrument - designed to examine the first light in the Universe and the formation of planets around other stars – will shortly be put through its paces in the space test chamber at the Science and Technology Facilities Council’s Rutherford Appleton Laboratory (RAL). The tests include ensuring it can survive the vibrations of a rocket launch and operate successfully in the cold vacuum of space.
The University of Leicester has played a pivotal role developing the mechanical engineering know-how behind one of four instruments to be placed on board the James Webb Space Telescope (JWST) to be launched in 2014 in order to succeed the current Hubble telescope.
The JWST telescope will produce the sharpest images yet of the farthest depths of the cosmos – thanks, in part, to the work of engineers and scientists at the University of Leicester Space Research Centre.
Space Research Centre Manager, John Pye said: “JWST will have four scientific instruments. One of these instruments – the Mid-Infrared Instrument (MIRI) is being designed and built by a European Consortium of scientific institutions and industry, including the University of Leicester.”
Dr Pye, who is also the University’s lead staff member for MIRI, added: “We provide the structural and mechanical engineering lead for the design and development of MIRI, and with colleagues at the Danish National Space Centre (DNSC) are responsible for the MIRI ‘Primary Structure’ that ensures that all the critical components of the instrument are held in close alignment even through the large vibrations and shock of launch (on a European Space Agency Ariane-V rocket) and during cool-down to the operational temperature of -266 C (just 7 degrees above ‘absolute zero’).”
The journey to space began a few months ago when the flight model of MIRI was integrated at RAL, from key parts that have been developed at institutes across Europe. Each of these parts of MIRI have already, separately, undergone exhaustive mechanical and thermal testing to make sure they can not only survive the rigours of a journey into space, but also remain operational for the life of the mission. Now the whole instrument will be tested using specially designed facilities developed at RAL to simulate the environment that the instrument will experience once in space.
"Bringing the Flight Model MIRI to readiness for the testing is the culmination of several years’ hard work and dedication from the teams all around Europe along with the efforts from our US colleagues. The fact that we are now at that point is testament to the tremendous team spirit in the MIRI Consortium and there will be many people waiting to hear the test results" said John Thatcher, the MIRI European project manager from Astrium Ltd.
Jon Sykes, of the University’s Space Research Centre, who is the mechanical engineering lead for the whole MIRI Consortium, added: “As a ground-breaking astronomical instrument, MIRI has presented many engineering challenges, which the multi-national design team have worked together to meet and produce a world-class facility.”
Dr Pye added: “The project has now successfully built and tested two full-size test models of MIRI. The international MIRI team has recently completed the assembly of the final – the Flight – model at the Rutherford Appleton Laboratory (RAL) in Oxfordshire. Now comes the “crunch time” when we have to “shake” the whole 100-kg instrument on a large vibration facility at RAL to ensure that it will withstand the rigours of the rocket launch and that all the high-precision optical components will not distort.”
Piyal Samara-Ratna, another of the Space Research Centre’s engineers deeply involved in the project said: “The Space Research Centre is leading these vibration tests, and carries a heavy responsibility to ensure that all goes well. This has involved many months of careful planning in preparation and has included extensive use of state-of-the-art Computed Aided Design (CAD) software to predict the behaviour of our instrument.”

The UK and MIRI
The UK’s lead role in the instrument involves taking responsibility for the overall science performance, the mechanical, thermal and optical design, along with the assembly, integration, testing and calibration. These roles are shared between the UK institutions in the partnership as follows:
• UK Astronomy Technology Centre (UKATC), Edinburgh – European science lead for the instrument; responsible for the overall instrument optical design and analyses, developing the overall calibration, and providing the spectrometer pre-optic subsystem.
• Rutherford Appleton Laboratory (RAL), Oxfordshire – responsible for overall instrument thermal design and analysis and production of all thermal hardware; assembly, integration, testing & verification of instrument including provision of bespoke test facilities; instrument ground calibration.
• University of Leicester – responsible for instrument overall mechanical design and analysis; provision of instrument primary structure (in partnership with Danish National Space Centre); provision of mechanical ground support equipment.
• EADS Astrium – overall project management and engineering leadership role; systems engineering; overall instrument product assurance leadership.
The James Webb Space Telescope
The James Webb Space Telescope is a joint project of NASA, ESA and the Canadian Space Agency. It is scheduled to launch in 2014 and will carry four scientific instruments: MIRI (mid-infrared camera and spectrograph), NIRSpec (near-infrared spectrograph), NIRCam (near-infrared camera), and TFI (tunable filter imager).
MIRI, the mid-infrared instrument, provides imaging, coronagraphy and integral field spectroscopy over the 5-28 micron wavelength range. It is being developed as a partnership between Europe and the USA - the main partners are ESA, a consortium of nationally funded European institutes, the Jet Propulsion Laboratory (JPL), and NASA's Goddard Space Flight Center (GSFC). The European consortium includes: Astronomy Technology Centre, UK; Astron, Netherlands Foundation for Research in Astronomy, Netherlands; CCLRC, Rutherford Appleton Laboratory (RAL), UK; CEA Service d'Astrophysique, Saclay, France; Centre Spatial de Liège, Belgium; Consejo Superior de Investigaciones Científicas (CSIC), Spain; Danish Space Research Institute (DSRI), Denmark; Dublin Institute for Advanced Studies, Ireland;
EADS Astrium Ltd, UK; Institut d'Astrophysique Spatiale (IAS), Orsay, France; Instituto Nacional de Técnica Aeroespacial (INTA), Spain; Laboratoire d'Astrophysique de Marseille
