The Canadian Space Agency (CSA) has provided the Webb Telescope with the Near-Infrared Imager and Slitless Spectrograph (NIRISS) scientific instrument and the Fine Guidance Sensor (FGS).

Thanks to the CSA's contribution, Canadian scientists are guaranteed observation time on the Webb Telescope and will be among the first to benefit from Webb's powerful instruments.
