How does the James Webb Space Telescope get ready for space while it’s still on the ground? Practice makes perfect. Different components of the telescope were first tested on their own, but now a fully-assembled Webb is putting all of its "training" for space together. This Tumblr will take you through all the testing that Webb has undergone, all to ensure that it will survive everything from the sound and vibration of launch, to operating correctly at cryogenic temperatures in space. https://na

Every time we build a better one, we see something we never imagined was out there." - Dr. John Mather Learn more about the science goals of the James Webb Space Telescope with Dr. Amber Straughn and Dr
