Yesterday, NASA confirmed the successful completion of the deployment of all components of the James Webb Space Telescope. Launched on December 25, 2021, this next-generation space telescope required several days of complex operations to deploy the various structures that make it up to reach its final configuration. This was a crucial phase that also included risks in the event that one of the systems didn’t work properly. Now the new phase opens with the calibration of the instruments, task-intensive to the point that it will take months before the James Webb can finally begin its scientific mission.
