Air Force One, with President Donald Trump aboard, flies over NASA’s Kennedy Space Center in Florida on May 27, 2020, ahead of the agency’s SpaceX Demo-2 launch. 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 Kennedy’s historic Launch Complex 39A. NASA astronauts Robert Behnken and Douglas 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.
