JWST's MIRI instrument experiences recurring issues.

NASA has detected a sensor glitch associated with the James Webb Space Telescope's Mid-Infrared Instrument (MIRI) during regular calibration and monitoring. The glitch is related to MIRI's Medium Resolution Spectroscopy (MRS) mode, which is receiving less light than expected at the longest wavelengths. MIRI observations will continue as planned, and engineers are investigating the cause and exploring mitigations to improve performance. One possible work-around strategy includes taking slightly longer exposures when observing at the longer wavelengths to increase the signal to noise.

Mysterious Glitch Detected in James Webb Space Telescope by NASA

NASA's James Webb Space Telescope has encountered a sensor glitch in its Mid-Infrared Instrument (MIRI) during a routine performance monitoring and calibration procedure. MIRI is one of the two most important components of the telescope and plays an important role in the images it captures. The glitch is specifically more visible while capturing lights in longer wavelengths. NASA will be taking a systematic approach to solve the problem and continue MIRI observations as planned.

James Webb Space Telescope encounters sensor problems in space

The James Webb Space Telescope's Mid-Infrared Instrument (MIRI) is experiencing less sensor "throughput" at the longest wavelengths, but NASA officials say there is no risk to the instrument and all other observation modes remain unaffected. The agency is investigating the cause of the issue and developing a plan to address it. MIRI has a camera and a spectrograph to detect light from distant objects and can also image faint objects in our solar system. The $10 billion telescope has been operating well since its launch on Dec. 25, 2021, and could operate for at least 20 years in space.
