Astronauts on the Soyuz spacecraft have arrived at the International Space Station (ISS) after a two-day journey from Earth.
The new crew will take over the ISS so that the current team can go home.
The Soyuz craft has been going back and forth to the ISS since the Columbia shuttle disaster in 2003.
It will take the spacecraft 10 days to return to Earth. Salizham Sharipov and Leroy Chiao have been on the ISS since October 2004.
