The James Webb Space Telescope is fully aligned. After a full review, NASA has announced that the JWST team has completed the seventh and final stage of telescope alignment. Following completion, the team held a series of key decision meetings and unanimously agreed that Webb’s ready to enter the final series of preparations, science instrument commissioning, ahead of full scientific operations.
The image below shows the alignment of the JWST across all of Webb’s instruments, including NIRSPEC, NIRCAM, MIRI, the Fine Guidance Sensor and NIRISS. The images show a marked change from when Webb detected its first photons in February. At that time, only the onboard NIRCAM, one of four cameras on Webb, was switched on and its image was unfocused. The team has made significant strides in just over two months.
