The Mid-InfraRed Instrument (MIRI) on the James Webb Space Telescope (JWST) provides measurements over the wavelength range 5 to 28.5 microns. MIRI has, within a single 'package', four key scientific functions: photometric imaging, coronagraphy, single-source low-spectral resolving power (R ~ 100) spectroscopy, and medium-resolving power (R ~ 1500 to 3500) integral field spectroscopy. An associated cooler system maintains MIRI at its operating temperature of < 6.7 K. This paper describes the driving principles behind the design of MIRI, the primary design parameters, and their realization in terms of the 'as-built' instrument. It also describes the test program that led to delivery of the tested and calibrated Flight Model to NASA in 2012, and the confirmation after delivery of the key interface requirements.

  1. From Young to Older Disks: JWST/MIRI Evidence for Fading Molecular Emission and Hints for Elevated C/O in Upper Scorpius

    astro-ph.EP 2026-06 unverdicted novelty 7.0 of 10

    Older Upper Scorpius disks show reduced molecular emission and hints of higher inner-gas C/O ratios than young disks, indicating chemical evolution consistent with pebble drift.

  2. IPA: Morphology and Kinematics of Molecular Hydrogen Winds in Five Young Protostars across the Mass Spectrum Observed with JWST

    astro-ph.SR 2026-08 conditional novelty 6.0 of 10

    Five protostars from 0.16 to 10,000 solar luminosities show nested, onion-like H2 outflows, with higher-excitation gas more collimated and faster, consistent with MHD disk wind launching.

  3. Dust production in the harsh environment of Sgr A* - MIRI/JWST observation of the O-rich asymptotic giant branch star IRS~3

    astro-ph.GA 2026-08 conditional novelty 6.0 of 10

    IRS 3 is an oxygen-rich AGB star with a multi-shell dusty envelope containing silicates, alumina, and water, at 0.17 pc from Sgr A*.
