2014 August 7 – 8
Members of the NIRISS Science Team met with representatives from the science teams for the other JWST instruments at STScI to exchange perspectives on the use of their respective "guaranteed" observing time and to explore synergies between different approaches to achieving JWST's scientific goals.

2014 June 22-27
NIRISS was well represented at the SPIE "Astronomical Telescopes and Instrumentation" meeting in Montréal. Five papers describing the instrument and its capabilities were presented by members of the NIRISS Instrument Development Team.

2014 June 16
NIRISS, along with the FGS and the other three 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. Performance verification of the NIRISS observing modes is scheduled for early September.

2014 June 2 – 3
The NIRISS Science Team met at the Université de Montréal to discuss the current status of the instrument, and to explore innovative ways to use the observing time that has been allocated to the team.

NIRISS completed its first suite of tests under cryogenic conditions in the large vacuum chamber at NASA's Goddard Space Flight Center. The tests featured "first light" observations for all the observing modes of NIRISS. Although a few glitches occurred, initial analysis of the test data show that NIRISS is performing marvelously.

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 Canadian Space Agency (CSA) reluctantly discontinued work on the Tunable Filter Imager (TFI) when it became clear that issues associated with the cryogenic operation of its Fabry-Perot etalon were unlikely to be resolved in time to meet the instrument's delivery schedule. Instead, CSA will provide a reconfigured instrument - the Near InfraRed Imager and Slitless Spectrograph (NIRISS) - that enhances the capabilities of the JWST Observatory while being simpler to fabricate and operate.
