BREAKING! NASA's JWST NIRISS has completed its post-launch preparations & now is ready for science

The Near-Infrared Imager and Slitless Spectrograph instrument (NIRISS), one of the James Webb Space Telescope's four primary scientific instruments, has completed its post-launch preparations and is now ready for science. The Single Object Slitless Spectroscopy (SOSS) capability was the last NIRISS mode to be checked off before the instrument was declared ready to begin scientific operations. A specialised prism assembly at the heart of the SOSS mode disperses the light of a cosmic source to create three distinct spectra (rainbows), revealing the hues of over 2,000 infrared colours collected simultaneously in a single observation. This mode will be used to investigate the atmospheres of transiting exoplanets, which are planets that periodically eclipse their star, temporarily dimming its brightness. By precisely comparing the spectra collected during and before or after a transit event, one can determine not only whether or not the exoplanet has an atmosphere, but also what atoms and molecules are present. René Doyon, principal investigator for NIRISS Siad in a statement: “I’m so excited and thrilled to think that we’ve finally reached the end of this two-decade-long journey of Canada’s contribution to the mission.", “All four NIRISS modes are not only ready, but the instrument as a whole is performing significantly better than we predicted. I am pinching myself at the thought that we are just days away from the start of science operations, and in particular from NIRISS probing its first exoplanet atmospheres. " After completing NIRISS post-launch commissioning activities, the Webb team will concentrate on testing the remaining five modes on its other instruments. On July 12, 2022, NASA's James Webb Space Telescope, a collaboration with ESA and CSA, will release its first full-colour images and spectroscopic data.
