Tim Peake made history on Tuesday when he became the first British astronaut to board the International Space Station.
The former military pilot will be spending six months on the ISS where he, alongside other crew, will be conducting a series of scientific experiments.
Fortunately, while there, Major Peake is able to communicate with Earth using data connections set up on the station.
After spending six hours on the Soyuz spacecraft, following the launch in Kazakhstan, Major Peake logged onto Twitter to let his followers know he had arrived safely.
Then, in the most British thing that's probably ever happened in space, Major Peake thanked the Queen for her well wishes and apologised to Elton John for not replying to his tweet particularly promptly.
