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.

The fresh crew includes NASA astronauts Zena Cardman and Mike Fincke, Kimiya Yui of the Japan Aerospace Exploration Agency (JAXA), and Oleg Platonov of Roscosmos.

The four astronauts of SpaceX's Crew-11 mission are scheduled to launch toward the International Space Station today (July 31), and you can watch the action live.
