NASA’s highly effective $10 billion area telescope is firing on all cylinders once more.
The James Webb House Telescope (JWST or Webb) returned to full science operations on Monday (Jan. 30), recovering from a glitch that affected certainly one of its devices.
The Webb workforce carried out days of testing and analysis after a “communications delay” on Jan. 15 brought on points with the telescope’s Close to Infrared Imager and Slitless Spectrograph (NIRISS) instrument, in accordance with a Tuesday (Jan. 31) assertion (opens in new tab) from NASA.
“Observations that had been impacted by the pause in NIRISS operations will probably be rescheduled,” stated the company in its transient assertion, noting the instrument was recovered efficiently on Friday (Jan. 27).

NIRISS was supplied by the Canadian House Company (CSA), so personnel from NASA and the CSA labored alongside each other for troubleshooting. The preliminary problem was a “communications delay inside the instrument, inflicting its flight software program to outing,” in accordance with a Jan. 24 assertion (opens in new tab) from NASA.
NIRISS can usually work in 4 totally different modes (opens in new tab), in accordance with NASA. The instrument could also be tasked with working as a digicam when different JWST devices are busy. Alternatively, NIRISS can have a look at mild signatures of small exoplanet atmospheres, do high-contrast imaging or look at distant galaxies.
Previous to the NIRISS glitch, a difficulty arose on one other Webb instrument in August 2022: a grating wheel contained in the observatory’s Mid-Infrared Instrument (MIRI). The wheel is required for only one of MIRI’s 4 observing modes, nonetheless, so the instrument continued observing throughout restoration operations. Work on recovering the affected mode, referred to as the Medium Decision Spectrometer, was accomplished in November.
In December, the JWST workforce additionally spent two weeks coping with a glitch that saved placing the telescope into protected mode, making science observations tough. A software program glitch within the observatory’s angle management system was pinpointed as the problem, affecting the route by which the telescope factors. The observatory bounced again comparatively rapidly from that drawback, resuming full science operations on Dec. 20.
