SpaceX delivers four astronauts to the ISS

SpaceX delivered a fresh crew to the International Space Station (ISS) on Saturday, making the trip in a quick 15 hours.

The four US, Russian and Japanese astronauts pulled up in their SpaceX capsule after launching from Nasa's Kennedy Space Centre. 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.

Moving in are Nasa's Zena Cardman and Mike Fincke, Japan's Kimiya Yui and Russia's Oleg Platonov - each of whom had been originally assigned to other missions.

"Hello, space station!" Fincke radioed as soon as the capsule docked high above the South Pacific.
