The 20-year lease requires NASA to pay more than $1.4 million annually to rent Hangar 703, a 422,000-square-foot building that once served as a home to Rockwell International and the B-1 bomber aircraft, according to a report submitted by Los Angeles World Airports, the agency that operates the airport. From staff reports The nation’s largest flying observatory and other aircraft used by NASA for scientific experiments will soon be housed at LA/Palmdale Airport under a proposal approved Monday by the Los Angeles airport commission. NASA’s Dryden Flight Research Center will move some of its operations to the Antelope Valley airport, which will eventually be home to the Stratospheric Observatory for Infrared Astronomy, a 747 jetliner armed with a giant telescope that gazes at the solar system. Modified versions of the ER-2, Gulfstream III and DC-8 jetliners will also be housed at the airport to conduct Earth and environmental studies, according to NASA officials. 160Want local news?Sign up for the Localist and stay informed Something went wrong.
