The 21-foot-wide primary mirror of the Webb Telescope is so large that it will have to fold up to fit into a rocket and be launched to space. Join host Mary Estacion as she travels to ATK in Magna, Utah, where the mirror’s foldable backplane “wings” have been constructed.
“Behind the Webb” is an ongoing series that follows the construction of the Webb Space Telescope, Hubble’s successor. Find more episodes at Hubblesite.org.
