The Mid-Infrared Instrument, a component of NASA's James Webb Space Telescope, underwent alignment testing at the Science and Technology Facilities Council's Rutherford Appleton Laboratory Space in Oxfordshire, England.

NASA's Goddard Space Flight Center in Greenbelt, Md. is managing the overall development effort for the Webb telescope. The Mid-Infrared Instrument is an international collaboration between NASA and the European Space Agency. Its focal plane modules, related electronics and software were built at JPL. The instrument's cooler is being built by Northrop Grumman Space Technologies in Redondo Beach, Calif., and managed by JPL. The instrument's optics are being built by an international consortium of European astronomical institutes.
