NASA astronauts Douglas Hurley (left) and Robert Behnken depart the Neil A. Armstrong Operations and Checkout Building at the agency’s Kennedy Space Center in Florida on May 27, 2020, in preparation for transport to Launch Complex 39A ahead of NASA’s SpaceX Demo-2 mission. The launch was scrubbed due to unfavorable weather conditions around Launch Complex 39A, and the next launch attempt will be Saturday, May 30. Liftoff of the SpaceX Falcon 9 rocket and Crew Dragon spacecraft is scheduled for 3:22 p.m. EDT from historic Launch Complex 39A. Behnken and Hurley will be 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.
