Wiltshire astronaut Tim Peake has been told he can stay in space for an extra couple of weeks.
Major Peake travelled to the International Space Station (ISS) in December, with American Tim Kopra and Russian commander Yuri Malenchenko.
The trio were due to return to Earth on June 5 but will now come back on June 18, almost two weeks later than originally planned.
Mission controllers are keeping them aboard the space station to keep it fully manned with six astronauts for as long as possible during the changeover of its crews.
Another three-strong crew will take off from Earth on June 21, three days after Major Peake's return.
Although I am looking forward to being back on Earth and seeing friends and family again, each day spent living in space is a huge privilege and there is much work to do on the station.
The 44-year-old father-of-two tweeted his excitement from space.
