For centuries, humans have dreamed of travelling into space. The dream only became a reality in 1961 when a Russian astronaut called Yuri Gagarin rocketed into space
and orbited around the Earth. Today, many men and women have travelled into space; most only go for a couple of days, but others go for months at a time. Even so, space remains a hostile environment for humans.Spacesuits are worn for protection and to provide air because there is no oxygen in space.
 

SPACE WEAR

The first astronauts had just one spacesuit per journey but today astronauts have different colour suits for the different jobs they do. One suit is for travelling to and from space. Then, in orbit, they wear specially designed casual clothes. When they are working outside there spacecraft they wear a suit called an extravehicular mobility unit (EMU). On top of this a strap-on motor called a manned manoeuvring unit (MMU) that can fly astronaut around.
