James Webb Space Telescope environmental testing
Fully assembled James Webb Space Telescope (JWST) at the completion of environmental testing at Northrop Grummans Space Park in Redondo Beach, California, USA. The test simulated the harsh conditions associated with a rocket launch to space, including noise, shakes, rattles and vibrations. It will be positioned near the Earth-Sun L2 Lagrangian point. By using infrared wavelengths, the JWST will be able to see through much of the dust that obscures visible light. It will also study dark matter, which is thought to form the majority of the matter in the universe.
