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.

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.
