Inspecting the MIRI Cryocooler

Technicians inspect a component of the cryocooler for the Mid-Infrared Instrument, or MIRI, part of NASA's James Webb Space Telescope. This photo was taken after the cooler had completed testing, and was taken out of the test chamber in preparation for being placed into its shipping container.

The cooler was shipped to the Northrop Grumman Aerospace Systems facility in Redondo Beach, California, on May 26, 2016. There, the cooler will be attached to the body of the Webb telescope.
