Astronauts
It takes several years to train to become an astronaut.
In this time, astronauts have to learn about science, space technology and how the International Space Station (ISS) works. They also have to be trained in basic medical care, learn how to scuba dive and also how to speak Russian!

Where Do Astronauts Live in Space?
Astronauts live on the International Space Station (ISS).
It is a large spacecraft and laboratory that orbits the Earth.
It is used for carrying out research on the effect of living and working in space.
The ISS is made up of different parts called modules. These are where the astronauts sleep, live and carry out experiments.
The ISS travels around the Earth at 27,700 km/hr.
It completes 16 orbits of the Earth a day.
It travels 350km above the Earth.
It is big enough to cover a football playing field!

What Do Astronauts Wear?
Click the question mark for an interesting fact!
When astronauts go on a spacewalk, they need to wear a protective spacesuit.

Helmet – the visor protects the astronaut’s eyes from the strong rays of the Sun.

Camera (on helmet) – used to send pictures back to Earth.

Radio – used to talk to other astronauts and Mission Control.
Spacesuit – keeps the astronaut’s body at the right temperature; it can get very cold and very hot in space.
Gloves – have a good grip. Astronauts need to train to carry out tricky tasks in these thick gloves
Display and Control Module (on the front of the suit) – the astronaut can control the spacesuit using these switches.
Primary Life Support System (on the back of the suit) – carries oxygen so that the astronaut can breathe. Water is also carried in this pack.

How Do Astronauts Sleep in Space?
Sleeping on board the ISS is a bit different for astronauts than it is for you at home.
Zero gravity means that the astronauts float around so they need to sleep in sleeping bags that they attach to the walls, ceiling or floor.
This means that they will not bump into anything as they sleep! Crew members also have their own cabins to sleep in.

What Do Astronauts Eat and Drink?
Astronauts can eat many of the same foods that you
eat at home but the way they are packaged has to
be different because food and crumbs will fly around
in zero gravity!
Food and drink may be packaged in aluminium foil or canned. Astronauts may need to add water to food if it is freeze-dried or they may need to heat it up before they eat it.
