A Russian rocket carrying a three-man crew has docked with the International Space Station.

The team of Russian, Japanese and American astronauts have joined colleagues already on board the ISS.

They are there to complete a $100bn research complex orbiting around 385km (240m) above Earth.

The astronauts are expecting an unprecedented level of traffic with nine spacecraft due over the coming weeks.
