Friday November 3 marks 17 years of continuous human habitation on the International Space Station (ISS). Astronauts from many nations have called the ISS home over the years as they undertook missions of maintenance and discovery.

The first components of what would become the constantly-manned ISS were first launched into space in the late 1990s, with the first astronauts making it their home in November 2000.

It was only after 12 years that the final parts were added. The ISS now weighs (or it would on Earth) 419,600kg (almost 1 million lbs), is roughly the width of a football field and cost roughly $100 billion to construct.
