glimpse of the early universe. The stunning first image is the result of some equally stunning engineering achievements. Orbiting the sun around 1 million miles away from earth, the JWST is in an environment that would be hard to imagine being more hostile. Bombarded by the sun’s unfiltered radiation in the cold vacuum of space, it still is not cold enough for it to function correctly without its “Cryocooler”. The MIRI (Mid- Infra-red instrument) device on board the telescope creates the images produced from the infrared radiation of the distant celes- tial bodies. Any heat generated by the instrument itself would spoil its readings so it must operate at a temperature below 7K. Key to achieving this was the Science and Technology Facilities


J


Council’s (STFC) RAL Space in the UK, which was responsible for the thermal engineering of the instrument. Reaching the point where MIRI could be used in space took years of designing and test- ing. The telescope launched in December last year and it has taken until the summer to reach the point where the instrument could be cooled to its operating temperature and the telescope could trans- mit its images to earth. Environmental testing is key to the success of this and other


space missions. Surviving the rigours of launch, operating correctly in zero gravity with no atmospheric pressure under a constant stream of ionising radiation for the lifetime of the mission requires the confidence gained in test laboratories throughout the world. Space development and testing organisations in the UK such as


the STFC’s RAL Space facility are providing the means to achieve such landmark scientific achievements as the images of distant galaxies, images that will provide astronomers with the data they need to continue in their quest to understand the cosmos. C&VT
