NASA astronauts Robert Behnken (left) and Douglas Hurley depart the Neil A. Armstrong Operations and Checkout Building at the agency’s Kennedy Space Center in Florida on May 30, 2020, in preparation for transport to Launch Complex 39A ahead of NASA’s SpaceX Demo-2 mission. Liftoff of the SpaceX Falcon 9 rocket and Crew Dragon spacecraft occurred at 3:22 p.m. EDT. Behnken and Hurley are the first astronauts to launch to the International Space Station from U.S. soil since the end of the Space Shuttle Program in 2011. Part of NASA’s Commercial Crew Program, this will be SpaceX’s final flight test, paving the way for the agency to certify the crew transportation system for regular, crewed flights to the orbiting laboratory.
