This isn't the first time a glitch negatively impacted Webb's science operations.
on January 24, Webb's Near Infrared Imager and Slitless Spectrograph instrument "experienced a communications delay within the instrument, causing its flight software to time out."NASA's post confirms that the NIRISS instruments are not currently used for scientific operations. "There is no indication of any danger to the hardware, and the observatory and other instruments are all in good health," the statement reads.
NIRISS was developed by the Canadian Space Agency , and NASA points out that it is working with the agency to resolve the issue. NIRISS can operate as a camera when Webb's other cameras are in use, though it can also be used to analyze light signatures to study exoplanets. It is also capable of conducting high-contrast imaging, and it can detect distant galaxies.
Webb's two most important instruments, the Near-Infrared Camera and Mid-Infrared Instrument , were not affected by the glitch.This isn't the first time the space observatory has suffered a glitch. In August, NASA officials noticed a wheel inside MIRI was showing signs of friction. This wheel is used to cycle the instrument into one of its four modes, sousing that specific mode while continuing MIRI observations in its three other modes. By November, NASA had found a workaround for the issue, and MIRI can now function using all four modes.
In December, Webb was repeatedly sent into safe mode — meaning its scientific instruments were automatically powered down — due to a software glitch in the observatory's attitude control system, which controls Webb's orientation. NASA reported in a December 20 statement that the issue had been resolved.On this day last year, Webb successfully completed the million-mile journey to its current home base.
