British astronaut Tim Peake started his journey into space, and his rendezvous with the International Space station, with a flight from Terminal 5 on Sunday, November 8.
His British Airways flight to Moscow allowed him to complete his final training before flying on to the Baikonur Cosmodrome in Kazakhstan for the launch.
His Soyuz rocket is scheduled to lift off at 11:02 GMT on December 15 and by 18:30 he should be floating through the hatch into the International Space Station to start his six-month stint.
