A SpaceX Falcon 9 rocket and Crew Dragon spacecraft stand poised for launch at historic Launch Complex 39A at NASA’s Kennedy Space Center in Florida on May 30, 2020, ahead of the agency’s SpaceX Demo-2 mission to the International Space Station. Liftoff occurred at 3:22 p.m. EDT. NASA astronauts Robert Behnken and Douglas Hurley are the first astronauts to launch from U.S. soil to the space station 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.
