Preparations for the third cryo-vacuum test (CV3) of the Integrated Science Instrument Module (ISIM) at NASA’s Goddard Space Flight Center continued throughout the summer. For the first time, the flight configuration of the ISIM was vigorously shaken – not stirred! – and bombarded by intense acoustical waves to simulate the harsh conditions of launch. Both NIRISS and FGS sailed through their “system functional tests” before and after these perturbations with no issues. Additional tests to confirm the electromagnetic compatibility of the subsystems of ISIM under conditions that simulate normal operations were also completed successfully. Now that the robustness of the ISIM has been demonstrated, it’s “full speed ahead” for the beginning of CV3 in late October!

FGS/NIRISS became the first instrument to be reinstalled in the Integrated Science Instrument Module (ISIM) following the "Half-Time Show." All the planned hardware changes were successfully completed and both instruments passed their electronic check-outs at room temperature with flying colors. FGS/NIRISS is ready for the final series of tests at NASA's Goddard Space Flight Center!

“Half-Time Show” activities for FGS/NIRISS began with the removal of the flight hardware from the Integrated Science Instrument Module (ISIM) in the large cleanroom at NASA’s Goddard Space Flight Center. The picture shows the moment of extraction, as captured by the ISIM WebbCam. The “Half-Time Show” is a busy time for the COM DEV team, since it represents the final opportunity to replace inferior hardware. For FGS, the priority is to replace both detectors and some of the read-out circuitry. Although it was the last package to be removed from ISIM, FGS/NIRISS will be the first to be reinstalled later in January.

FGS, along with the four science instruments, began the second intensive cryogenic test campaign in the large vacuum chamber at NASA's Goddard Space Flight Center. The campaign will last for about 3 .5 months, and will exercise the capabilities of all the instruments.
2013 March 1
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.
2011 April 6
The FGS and TFI underwent an alignment and risk mitigation campaign in a cryogenic environment at the David Florida Laboratory (DFL) in Kanata, Ontario (Canada) in Dec 2010 and Jan 2011. Preparations are currently underway for the final test activities in the summer and fall of 2011.
2010 September 8
The Canadian Space Agency has delivered engineering test unit (ETU) of the Fine Guidance Sensor to NASA's Goddard Space Flight Center. The ETU will be used to test interfaces between the FGS instrument and the Webb Observatory. For more information read CSA New Release or NASA Feature.
