An international crew of four astronauts launched toward the International Space Station from Florida on Friday aboard a SpaceX rocket, embarking on a routine NASA mission that could be the first of many to last a couple months longer than usual.

SpaceX launched the Crew-11 on Aug. 1, sending four astronauts to the International Space Station on the record-breaking sixth flight of its Crew Dragon Endeavour spacecraft.

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.
