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.

Every mission to space is a milestone. But for the astronauts of Crew-11, their time at the International Space Station will be historic.
