The International Space Station is the biggest object ever made orbiting the Earth. It’s been up there 20 years!

In one day, it goes round our planet 16 times.

The station is as big as a football stadium and weighs 400 t; that’s the weight of 25 buses.

In this giant laboratory, there are 6 people permanently working on science experiments and the station’s maintenance.

They especially test living conditions in space to prepare for future trips.

So what’s it like to live in this incredible space station?

Orbiting the Earth, in weightlessness, everything floats.

Muscles have to be reinforced so they don’t go soft. That takes 2 hours of sport every day.

For meals, the astronauts eat food in a thick sauce that sticks to the fork. They drink using straws. Like that, food and drink stays put.
