Webb Telescope in full focus, ready for instrument commissioning
Alignment of the James Webb Space Telescope is now complete. After full review, the observatory has been confirmed to be capable of capturing crisp, well-focused images with each of its four powerful onboard science instruments, including the Canadian Space Agency's NIRISS. Webb is ready to move forward into its next and final series of preparations, known as science instrument commissioning. This process of setting up and testing the instruments will take about two months before scientific operations begin in the summer.
The alignment of the telescope across all of Webb's instruments can be seen in a series of images that captures the observatory's full field of view.
Webb's mirrors are now directing fully focused light collected from space down into each instrument, and each instrument is successfully capturing images with the light being delivered to them. The image quality delivered to all instruments is as good as physically possible, given the size of the telescope.
