   How much does a SOFIA telescope weigh?

   • The telescope weighs 19 tons (38,000 pounds) and is mounted in the rear fuselage of a highly modified Boeing 747SP aircraft. Flying at altitudes of between 39,000 to 45,000 feet (12 – 14 kilometers) and above 99 percent of the water vapor in the atmosphere, SOFIA facilitates observations that are unobtainable from telescopes on the ground.

   When was the first light collected by the SOFIA telescope?

   • "First light," the first time the telescope collected astronomical data, was achieved on May 25, 2010. Infrared light from the red supergiant star Antares, emitted more than 550 years ago, was observed by SOFIA using a camera called the Faint Object Infra-Red Camera for the SOFIA Telescope, or FORCAST, developed by Cornell University.

   What happened to the SOFIA observatory?

   • The observatory, fitted with an 8.9-foot-wide (2.7 meters) telescope with a nearly 20-ton mirror, used a door in the side of the aircraft to peer at the sky. A collaboration between NASA and the German Aerospace Center (known by its German acronym DLR), the SOFIA project was prematurely ended in 2022 after operating for 12 years.
