The James Webb Space Telescope is experiencing an issue with one of its instruments, the Near Infrared Imager and Slitless Spectrograph, or NIRISS. The instrument is currently offline with no indication of when it will be back online, but engineers are working to address the issue and the telescope hardware remains safe.
In the case of James Webb, the problem with the NIRISS instrument was due to a communication delay. “On Sunday, Jan. 15, the James Webb Space Telescope’s Near Infrared Imager and Slitless Spectrograph experienced a communications delay within the instrument, causing its flight software to time out,” NASA wrote in a statement.
The planned scientific observations which were scheduled to use NIRISS will now be rescheduled, according to NASA.
