Wide-field Infrared Explorer
WIRE was a solid-hydrogen cooled imaging telescope designed for studying starburst galaxy evolution. As the fifth mission in the Small Explorer (SMEX) program, WIRE was launched in March 1999 from Vandenberg Air Force Base via an Orbital Sciences Pegasus XL.
Under contract to JPL, SDL designed, assembled and tested the telescope, including the mirrors, filters, and mechanical structure. SDL worked with Boeing to define the FPA mount assemblies and integrated these into the completed telescope.
SDL provided all management and instrument engineering for WIRE, including management of Boeing North America for production of the focal plane arrays and Lockheed Martin Missiles and Space for production of the solid hydrogen cryostat.
