The MIRI engineering model, ready for testing
Today, and for the rest of this week, I’m in the city of Leuven, Belgium. Together with some colleagues from the Catholic University of Leuven and various other institutes in Europe I’m spending a few days working on some aspects of calibration and testing for MIRI, the mid-infrared instrument for the James Webb Space Telescope. The JWST, although offcially its “successor”, will differ from Hubble in that it will be optimised for observations in the infrared, rather than the optical or ultraviolet. Although great science can be done at the shorter wavelengths, achieving top notch image quality is more demanding at shorter wavelengths – with the costs for JWST far exceeding initial estimates as it is, who knows what the budget would have had to be for an optical JWST?
