NASA and SpaceX's Crew-11 mission is made up of two U.S. astronauts, one from Japan and a Russian cosmonaut. They'll be aboard the International Space Station for six months conducting research.

The four U.S., Russian and Japanese astronauts pulled up in their SpaceX capsule after launching from NASA’s Kennedy Space Center. They will spend at least six months at the orbiting lab, swapping places with colleagues up there since March. SpaceX will bring those four back as early as Wednesday.
