NASA investigating glitch on James Webb Space Telescope camera

James Webb Space Telescope’s ultracold camera has experienced a technical glitch that is forcing the ground team to postpone some observations. 

The problem affected the James Webb Space Telescope‘s Mid-Infrared Instrument’s (MIRI) grating wheel, which allows scientists to choose the wavelength of light they want to focus on. The wheel is used in only one of MIRI‘s four observation modes, the medium-resolution spectroscopy (MRS) mode, in which the camera takes not images but light spectra (fingerprints of light absorption of the various chemical elements in the observed objects).
