Yuri Gagarin, Neil Armstrong and Buzz Aldrin are just a few of the famous names that have been sewn onto astronauts' uniforms.
Gagarin was the first person in space and is referred to as a cosmonaut (as are all Russian space explorers). With China now sending taikonauts into space, it seems more and more countries will be taking up the challenge of manned spaceflight programmes.
