The James Webb Space Telescope marked another year of
significant progress in 2012 as flight instrumentation was
completed and delivered to NASA. The year brought forth the
delivery of two types of flight mirrors, the Mid-Infrared
Instrument (MIRI), the Fine Guidance Sensor and Near-Infrared
Imager and Slitless Spectrograph (FGS/NIRISS), and the
completion of the center section of the primary mirror
backplane. The Webb project modified the historic Chamber A at
NASA's Johnson Space Center, Houston, Texas, to enable the Webb
telescope's optics and instrument systems to be tested. In
addition to the telescope and test chambers coming together,
spinoff technology from the Webb has already been used in
industries to improve people's lives. On Sept. 17, 2012, two
primary mirror segments that will fly aboard NASA's James Webb
Space Telescope arrived at NASA's Goddard Space Flight Center in
Greenbelt, Md. The flight secondary mirror and a third primary
mirror segment arrived at NASA Goddard on Nov. 5, 2012, and are
