The Midcourse Space Experiment (MSX), a Ballistic Missile Defense Organization satellite, was launched in April 1996. The first ten months of the mission were devoted to mid-infrared observations with a solid hydrogen-cooled telescope. This instrument had five line-scanned focal plane arrays that spanned the spectral region from 4.2 to 26 microns. For more info, see MSX mission background information.

If you are looking for the original IRSA MSX Image Server and Catalog Overlays, it can be found here.

Also available are MSX image "cutouts" using IRSA's Cutouts Service, which is a general tool to create single or multiple small FITS (and JPEGs) image cutouts of datasets archived at IRSA.

MSX images are available for the regions shown above (an IRAS 100 micron ISSA image with a J2000 Equatorial grid is shown as background). In the Galactic plane, some areas are available both as standard mosaics and from higher sensitivity images (shown in yellow). Images of galaxies, star-forming regions out of the Galactic plane are indicated in yellow and IRAS Gap regions in red. Either type in a coordinate or click on a region to get a close up of the MSX region; the size of the search is adjustable.
