Watch the Soyuz spaceship dock at the International Space Station

A Russian Soyuz spacecraft, with three astronauts on board, has docked at the International Space Station (ISS).

After a two day journey in one American astronaut and two Russian cosmonauts arrived and they'll work on board the station until September.

The ISS is a floating research lab in space and it orbits about 240 miles away from Earth.

As well as a safe arrival there was another reason to celebrate - it was the American astronaut, Joseph Acaba's, birthday too!
