  • Media: Interview Requests etc
  • Where Is Webb? Follow the schedule and current status of Webb on its journey to L2 orbit, its deployment, its commissioning and finally the release of its first images and the start of science operations. See Webb in 3d in a 3d solar system ( and compare it to Hubble and other spacecraft in 3d). The page constantly updates as Webb travels, deploys, cools to operating temperature and moves through its commissioning phases ultimately leading to the release of its first images.
  • Explore Webb's Deployment and Commissioning Sequence - Webb is the largest telescope ever launched into space. In the ~2 weeks after launch, Webb unfolds from its compact launch configuration into its operational configuration which is nearly the size of a tennis court. From that point, Webb moves through its commissioning phases leading up to the release of it's first images. Explore the entire process interactively and explore status updates, videos, blogs and more as it goes through each step.
