In outer space there is no air to breathe and the temperature can quickly change from being very hot to very cold. To survive astronauts must wear spacesuits. They are like an astronaut’s personal spacecraft, allowing them to do important jobs – such as repairing the space station.
Helmet
Astronauts see out of a clear plastic bubble, and also have a visor to protect them from the Sun’s harmful rays.
Lots of layers
Spacesuits have 14 layers of material to help keep astronauts safe. Some of these layers protect them from dangerous objects that fly through space.
Life support system
Worn like a backpack, the life support system contains oxygen for the astronaut to breathe, and a battery for electrical power.
Display unit
Astronauts operate their life support system using controls on their display unit.
Gloves
Spacesuit gloves have heaters in he fingertips to stop an astronaut’s fingers from getting cold!
Boots
Astronauts can attach their boots to special foot restraints on the space station to make working in space easier.
Flying free
Manned Maneuvering Unit was used by astronauts in the 1980s to travel in space without being tied to their spacecraft. Today, astronauts have smaller versions in case of emergencies.
