JWST MIRI (2004 – 2010)


The James Webb Space Telescope (JWST) is a  very large, infrared space telescope that will be launched in 2018. It results from a collaboration NASA-ESA With its very large mirror of 6.5m in diameter it will be the successor of the Hubble Space Telescope. Working essentially in the infrared it will observe the early phases of the formation of galaxies and stars.

MIRI is one of three instruments on this space telescope and will provide imaging, spectroscopy and coronagraphy at wavelengths between 5 and 28 μm. The project is an international partnership (50 / 50) between JPL and a nationally funded consortium of European institutes, working with ESA and NASA. MIRI is designed to meet the science requirements of JWST for mid‐IR capabilities. The European Consortium will design, build, integrate, and test the instrument "optical bench assembly" (consisting of an imager and two spectrometer modules, together with the focal planes and the associated electronics provided to us by JPL). It is led by Gillian Wright (UK), along with France, Germany, The Netherlands, Sweden, Ireland, Switzerland, Denmark, Spain and Belgium. The project is managed by EADS‐Astrium, Ltd.

The contributions of the CSL to MIRI are the Input Optics and Calibration Unit (IOC), the Instrument Control Electronics (ICE) and various optics (mirrors and prisms) for the French Imager (MIRIM).
