On 16 March, Channel 4 will host a live broadcast from the International Space Station (ISS) as part of their Live from Space season. Viewers will be able to interact with the astronauts as they travel through one 90 minute orbit of the Earth.
The first component of the station was launched into space on 20 November 1998, over 15 years ago. Since then, the space lab has undergone numerous facelifts and grown considerably to become the largest manmade body in orbit.
Take a look at how the International Space Station has evolved over time in the gallery below.
