The success and longevity of the Hubble Space Telescope would not have been possible without the service of the 32 astronauts who flew across six missions to launch and repair the telescope. The results of their dedication and expertise helped to double Hubble’s lifespan and subsequently led to countless significant discoveries, furthering our knowledge of the universe.
Hubble astronauts come from a diverse range of professions: fighter pilots, oceanographers, veterinarians and more. They have advanced countless frontiers – professionally, physically, and even culturally – and have broken records both in space and on Earth.
