<p>NASA's Fine Guidance Sensor/Near InfraRed Imager and Slitless Spectrograph (FGS/NIRISS) is getting a lift in the giant clean room at NASA Goddard Space Flight Center in Greenbelt, M
d. In this photo, the FGS/NIRISS was being lifted for placement on a master tool for key measurements prior to installation onto its flight structure later.
</p><p>The Canadian Space Agency's contribution to the Webb mission, the FGS/NIRISS arrived at NASA Goddard on July 30, 2012. The FGS/NIRISS is the second instrument to arrive at NASA Goddard that will fly aboard the James Webb Space Telescope. The Fine Guidance Sensor will enable the telescope to accurately and precisely point at the correct, intended objects for it to observe.
