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 optical performance of the telescope continues to be better than the engineering team’s most optimistic predictions. “These remarkable test images from a successfully aligned telescope demonstrate what people across countries and continents can achieve when there is a bold scientific vision to explore the universe,” said Lee Feinberg, Webb optical telescope element manager at NASA’s Goddard Space Flight Center. 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. This process will take about two months before scientific operations begin in the summer. Upon completing the seventh and final stage of telescope alignment, the team held a set of key decision meetings and unanimously agreed that Webb is ready to move forward into its next and final series of preparations, known as science instrument commissioning. ![]() 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. Alignment of NASA’s James Webb Space Telescope is now complete. ![]()
