Ground control is calling it a “bulls eye landing”.
A Russian Soyuz space capsule has landed safely in Kazakhstan with three astronauts on board.
The American and two Russians are back on earth after 164 days in space.
Since April they had been manning the International Space Station.
One team of astronauts remains on the station and another is due to replace them in November.
The arrival of the new team was delayed while investigations are carried out into a Russian launch accident involving an unmanned cargo ship bound for the station.
Sixteen nations are involved in the recently completed International Space Station, which has cost tens of billions of euros.
With the retirement of the US space shuttles this summer, crews can reach the station only aboard Russian rockets.
