Countdown clocks are ticking toward the launch of a new era in human spaceflight. With today's scheduled launch of NASA's SpaceX Demo-2 mission at the agency's Kennedy Space Center in Florida, American astronauts will once again launch on American spacecraft from American soil to the
International Space Station. Liftoff of the SpaceX Falcon 9 rocket and Crew Dragon spacecraft carrying NASA astronauts
Robert Behnken and
Douglas Hurley is targeted for
4:33 p.m. EDT from Kennedy's historic Launch Complex 39A.
