NASA launched a SpaceX rocket carrying astronauts to the International Space Station. The flight includes astronauts reassigned from Boeing’s delayed Starliner mission and may extend beyond six months in space.

NASA’s SpaceX Crew-11 will launch from the Kennedy Space Center in Florida on Thursday. Liftoff is expected for 12:09 p.m. The four astronauts, NASA’s Zena Cardman and Mike Fincke, Japan Aerospace Exploration Agency astronaut Kimiya Yui, and Roscosmos cosmonaut Oleg Platonov, will fly aboard the “Endeavor,” a SpaceX Dragon spacecraft.
