NASA Referees Test of Footballs vs. Webb Telescope

The video discusses the construction and testing of the James Webb Space Telescope, highlighting its advanced capabilities and the rigorous testing it undergoes to withstand launch conditions. The telescope's instruments are designed to detect infrared light and must operate at extremely low temperatures. Various tests, including vibration, centrifuge, and acoustic tests, ensure the telescope's durability. The video also explains the importance of testing materials at cryogenic temperatures and outlines the final preparations before the telescope's launch.
