Ball Aerospace, Boulder, Colo., under contract to Northrop Grumman, is responsible for the Webb’s optical technology and lightweight mirror system. On September 17, 2012, Ball Aerospace shipped the first two mirrors in custom containers designed specifically for the multiple trips the mirrors made through eight U.S. states while completing their manufacturing. The remaining 16 mirrors will make their way from Ball Aerospace to Goddard over the next 12 months as they await telescope integration in 2015.
