James Webb Space Telescope tower test
Once in space, NASA’s James Webb Space Telescope (JWST) must extend the spacecraft’s warm electronics away from its ultra-sensitive gold mirror and scientific instruments. JWST is designed to pick up faint heat signatures from faraway astronomical objects—including exoplanets—and must be kept extremely cold to work.
