NASA has paused some of the James Webb Space Telescope’s operations after discovering a glitch with one of the craft’s integral imaging instruments. One of the instrument’s mechanisms, described as “a grating wheel that allows scientists to select between short, medium, and longer wavelengths,” seemed to exhibit “increased friction” during setup. This mode is integral to the Webb being able to capture imagery of stars and exoplanets that our eyes alone would be unable to see because their wavelengths are simply too long for our feeble peeps.Read Long Article
