arXiv:2608.13873v1 Announce Type: new Abstract: MIRI, the Mid-Infrared Instrument on the James Webb Space Telescope, is the only instrument sensitive to wavelengths longward of 5 um on the observatory. In this regime, MIRI brings order-of-magnitude improvements over past instruments and missions in a wavelength range that is challenging or impossible to access from the ground. As such, MIRI occupies a unique parameter space, offering unparalleled capabilities in all areas of astrophysics, from the Solar System to the most distant galaxies in the Universe. We continue to make operational improvements to MIRI, four years into its operational lifetime, to create new observing opportunities, improve performance, and enhance its scientific return. In this paper we will describe several such improvements, and their anticipated impact on MIRI and JWST science.
