The Mid-Infrared Instrument (MIRI) on JWST provides imaging and spectroscopic
measurements over the wavelength range 5-27 µm. It is a multi-purpose instrument that significantly
extends the wavelength coverage of JWST.
MIRI is jointly developed by the US and a nationally funded European Consortium under the
auspices of the European Space Agency. George Rieke (UoA) and Gillian Wright (Royal
Observatory Edinburgh) are the MIRI Science Leads. JPL chairs joint overall
management and system engineering teams.
