British astronaut Tim Peake and two colleagues have been welcomed aboard the International Space Station after a six-hour journey from Kazakhstan.
No Brit has undertaken such a mission - or even left Earth - in more than two decades.
Mr Peake will be onboard the ISS for six months.
British astronaut Tim Peake has tweeted the Queen from space to thank her for her message of support as he blasted into orbit on board the Soyuz rocket on Tuesday.
Earlier Major Peake tweeted Sir Elton John from space, quoting his hit song Rocket Man apologising for his late response after spending his first full day on the International Space Station (ISS).
He quoted "Zero hour 9am", a lyric from Sir Elton's popular song Rocket Man, which tells the story of a lonely astronaut in space who is thinking about his family.
Major Peake will be separated from his wife Rebecca and sons Thomas, six, and Oliver, four, for nearly six months during the Principia mission.
The parents of British astronaut Tim Peake missed a phone call from their son made from the deck of the International Space Station.
British astronaut Tim Peake has tweeted his first picture of his view from the International Space Station (ISS).
British astronaut Tim Peake may have only been in space for three days, but he has already been busy.
