Pictures: How do you train for a mission into space?
See how British astronaut Tim Peake is getting ready for his mission to the International Space Station.
Former helicopter pilot Major Tim Peake, will live and work on the space station for six months. In preparation for his launch in November 2015, he is being put through intensive training by the European Space Agency (ESA).
Whilst in space Major Peake will be living in zero gravity. To get used to the feeling of weightlessness astronauts are trained aboard planes like the Airbus A300 Zero-G. This plane can freefall through the air with no force other than gravity pulling on it to generate 20 seconds of weightlessness at a time.
Astronauts also use pools to try and experience what it's like to walk and work in zero gravity.
During this 12-day mission Major Peake and six crewmates lived in cramped conditions, performed ‘waterwalks’ and had to solve problems as a team. The mission also tested equipment and techniques for future space exploration.
Orlan suits allow astronauts to venture outside the ISS for up to seven hours to install new equipment or carry out maintenance and repair. Here Major Peake is learning how to inspect a Russian Orlan space suit during training at the Gagarin Cosmonaut Training Centre in Russia.
The Soyuz spacecraft is the the main vehicle for transporting crew to and from the ISS. Astronauts must learn how to control and doc the Soyuz in this simulator. Major Peake will travel to the ISS on a Soyuz rocket for real from Baikonur Cosmodrome next year.
Cave training prepares astronauts to work as an international team in real exploration conditions. On this training exercise astronauts were sent underground to survive and explore caves in Italy for almost a week. Astronauts need to get used to small spaces, little privacy, technical challenges as well as limited equipment and supplies – just like it will be in space.
What do you need to do to board the International Space Station (ISS) and see a view like this? Tim Peake, the UK's first official astronaut, has been finding out!
They learn basic skills such as how to attach themselves to the ISS on space walks, the use of special tools, communicating with crewmates and with the control room and how to keep full awareness in a challenging environment like space.
