NIRISS and the FGS became the first flight instruments to be attached to the Integrated Science Instrument Module (ISIM), which is currently located in the large clean room at NASA's Goddard Space Flight Center.
NIRISS and the Fine Guidance Sensor successfully completed room-temperature functional tests at NASA's Goddard Space Flight Center.2012 November 15
NIRISS and FGS became the first JWST instruments to be accepted formally by NASA during the Delivery Review Board meeting at the Goddard Space Flight Center.
2012 July 30
The Canadian Space Agency delivered NIRISS and the Fine Guidance Sensor to NASA's Goddard Space Flight Center on July 30, 2012. There the instruments will be inspected, tested, and incorporated into Webb's Integrated Science Instrument Module (ISIM).
The successful completion of the Test Review Board marked the formal conclusion of the FGS/NIRISS cryovac performance test campaign.
The FGS and the TFI hardware that will become NIRISS began its final cryogenic performance test campaign at the Canadian Space Agency's David Florida Laboratory in Kanata, Ontario. The tests are scheduled to be completed in early January, 2012.
