Nasa james webb telescope completely aligned12/23/2023 The telescope is designed to peer back so far that scientists will get a glimpse of the dawn of the universe about 13.7 billion years ago and zoom in on closer cosmic objects, even our own solar system, with sharper focus. FILE – In this Apphoto provided by NASA, technicians lift the mirror of the James Webb Space Telescope using a crane at the Goddard Space Flight Center in Greenbelt, Md.This image released by NASA on Tuesday, July 12, 2022, shows the bright star at the center of NGC 3132, the Southern Ring Nebula, for the first time in near-infrared light.The telescope is designed to peer back so far that scientists can get a glimpse of the dawn of the universe about 13.7 billion years ago and zoom in on closer cosmic objects, even our own solar system, with sharper focus. This image provided by NASA on Monday, July 11, 2022, shows galaxy cluster SMACS 0723, captured by the James Webb Space Telescope.This mosaic was constructed from almost 1,000 separate image files, according to NASA. This image provided by NASA on Tuesday, July 12, 2022, shows Stephan’s Quintet, a visual grouping of five galaxies captured by the Webb Telescope’s Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI).It is a hot, dense white dwarf star, according to NASA. This image released by NASA on Tuesday, July 12, 2022, shows the Southern Ring Nebula for the first time in mid-infrared light.Then the lengthy process began to align the mirrors, get the infrared detectors cold enough to operate and calibrate the science instruments, all protected by a sunshade the size of a tennis court that keeps the telescope cool. It launched into space in December from French Guiana in South America and reached its lookout point 1 million miles from Earth in January. They are now working to determine how other micrometeoroids could impact Webb’s mirrors, how many of these asteroid fragments there are, and whether the telescope should be adjusted to spend less time pointing toward orbital motion, where it may be at greater risk of being struck by a micrometeoroid.ĭepending on its fuel usage, and expected degradation to the telescope, Webb could survive for more than 20 years, according to engineers. The damage to C3, however, has engineers investigating whether the impact was rare, meaning it could happen once every few years, or if Webb is “more susceptible to damage by micrometeoroids than pre-launch modeling predicted.” Webb has been hit by at least six micrometeoroids since its December launch, equal to roughly one impact per month, matching expectations, according to their report.
