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.
The parents of British astronaut Tim Peake have joked they wished he had chosen to be a banker instead, as he prepares for a six-month mission aboard the International Space Station.
Speaking ahead of the launch in Kazakhstan, Angela Peake said: "I'm just glad that we're almost there now - Tim has worked very hard for this and it has been a long haul."
"We used to joke when this first started - I said: 'I wish you could be a banker."
Major Peake's father Nigel added that he was "enormously proud" of his son and thanked the British public for the "stupendous" support that he had been shown in the lead-up to the launch.
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.
