The Secondary Mirror of the JWST Pathfinder (test) Telescope is stowed in the large cleanroom at Goddard Space Flight Center. Instrumentation will be added to the telescope arms to monitor temperatures during cryogenic testing in the Chamber A thermal vacuum facility at Johnson Space Center in 2015.
