A computer games millionaire has blasted into space and is heading for a 10 day holiday on the International Space Station (ISS).
Richard Garriott paid a whopping £20 million for the trip aboard the Russian Soyuz TMA-13 spacecraft.
The American is following in the footsteps of his dad, Owen Garriott, who spent two months taking photos of Earth from the ISS in 1973.
Owen will support his son from mission control in Moscow.
Mr Garriot launched into space with US astronaut Mike Fincke and Russian flight engineer Yuri Lonchakov.
Mr Fincke and Mr Lonchakov will replace the station's current crew - commander Sergei Volkov and flight engineer Oleg Kononenko who have spent six months in space.
They'll fly home with the tourist on 23 October.
While Mr Garriot's up there he plans to do some experiments and take photos to record how the Earth's surface has changed in the 35 years since his father went into space.
