The NIRISS instrument on the James Webb Space Telescope has malfunctioned.

A new problem has arisen for the James Webb Space Telescope. The NIRISS instrument has failed. NIRISS (Near-Infrared Imager and Slitless Spectrograph) consists of a camera and a slitless spectrograph that operates in the near and mid-infrared ranges. NIRISS also spectroscopically analyzes exoplanet atmospheres. It has been shut down since January 15th due to a communications error. An internal communication error led to a software time-out. There are no signs that the instrument has been damaged in any way. The other instruments are working normally, according to AstroNews.
