What Is It?

The International Space Station is a home and science lab in space. It orbits low Earth orbit, about 400 kilometres above our planet. Scientists go there to do experiments in microgravity.

It is a research station that is also the biggest spacecraft people have ever built. Its inside is about the size of a Boeing 747 airplane.

Who Helps Run It?

Five space agencies work together to run the station. They are NASA from the United States, Roscosmos from Russia, ESA from Europe, JAXA from Japan, and CSA from Canada. Fifteen countries take part in the program.

It was the first space station built, cared for, and visited by many countries working together.

A Home in Space

The station circles Earth about 15.5 times every day. Its body and solar panels together are about the size of a football or soccer field.

The first parts, Zarya and Unity, were sent up in 1998. Since 2 November 2000, people have lived on the station without a break. This is the longest time people have lived in space. More than 290 visitors from 26 countries have come to stay for a while.

The station is planned to keep working until the end of 2030. Visitors still arrive on spacecraft such as Crew Dragon.
