Experience the closest thing to standing next to the actual JWST

Joining other historic NASA missions like Apollo, Voyager, and the Discovery Space Shuttle, Webb’s Optical Telescope Element Pathfinder has made its way to the Steven F. Udvar-Hazy Smithsonian museum for permanent display. The Pathfinder is the largest intact mirror support structure of its kind, comprised of exotic lightweight materials invented for the purpose of seeing near to the very limits of the observable universe. This unique piece of hardware served a critical role in ensuring mission success by enabling engineers to build a comprehensive testing program to validate and ensure the most complicated optical system ever built would work flawlessly after launch.
