The Webb Space Telescope has been dutifully beaming again unbelievable photos of the cosmos since its “perfect” alignment earlier this 12 months—but nothing is solely good, even a $10 billion telescope. One of Webb’s observing mechanisms has apparently run right into a little bit of hassle, and mission engineers are working to determine an answer.
On August 24, a mechanism used to assist Webb’s medium-resolution spectroscopy (MRS) skilled “increased friction” whereas being arrange for a science remark, NASA said in a weblog submit on Tuesday. The house company referred to as for a gathering of an anomaly overview board on September 6 to “assess the best path forward.” As the board works to investigate the difficulty and develop methods to resolve it, NASA has paused observations utilizing this specific mode.
The MRS observing mode is a part of Webb’s Mid-Infrared Instrument (MIRI), which makes use of a digicam and a spectrograph to see gentle within the mid-infrared a part of the spectrum (wavelengths which might be longer than what human eyes can see). MIRI has 4 observing modes: imaging, coronagraphic imaging, low-resolution spectroscopy, and medium-resolution spectroscopy. MRS is beneficial for observing indicators from the interplay of sunshine and matter, just like the emissions coming from molecules and mud in planet-forming disks.
The glitch in query affected a mechanism that capabilities like a “grating wheel” for the MRS observing mode, permitting scientists to pick between quick, medium, and longer wavelengths when making observations utilizing that individual mode, in response to NASA.
For now, that mode is on maintain whereas NASA tries to repair the difficulty. “The observatory is in good health, and MIRI’s other three observing modes – imaging, low-resolution spectroscopy, and coronagraphy – are operating normally and remain available for science observations,” the house company wrote.

Webb has recently wowed us with images of neighboring planets Mars and Jupiter, but the telescope is also gearing up to bring us unprecedented views of the distant universe from its perch in space 1 million miles away from Earth. Webb is expected to operate for about 20 years or longer, so hopefully it can overcome a few technical glitches along its journey.
