SPACE reports that the James Webb Space Telescope (JWST) mission team members “have begun the three-month process of aligning the $10 billion Webb.” For the first time, “photons from distant stars traveled through the entire telescope and were detected by Webb’s Near Infrared Camera (NIRCam) instrument.” NASA officials wrote Thursday, “This milestone marks the first of many steps to capture images that are at first unfocused and use them to slowly fine-tune the telescope. This is the very beginning of the process, but so far the initial results match expectations and simulations.” The alignment process involves seven phases, “which will key on imagery Webb captures of the bright star HD 84406.”
