The James Webb Space Telescope, or the JWST, is a successor to 2 of NASA’s great observatories, the Hubble Space Telescope and the Spitzer Space Telescope. It’s on the pad ready to launch hours from now and it’s famous for being the most expensive scientific spacecraft ever built thanks in large part of the contractors taking decades longer than expected to get the vehicle ready for flight.
And I hope that 6 months from now it’ll be famous for being one of the most important scientific instruments built by humanity, looking back closer to the start of the universe to help us understand how we got to where we are now.
