SpaceX delivered a new crew to the International Space Station on Saturday in a 15-hour trip from NASA's Kennedy Space Center. 

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

The astronauts will be in space for at least six months. The current crew is expected to return to Earth by Wednesday, according to the Associated Press.
