Big, Bigger, Biggest Season 2 Episode 6

Space Station

Explore the giant technological leaps forward that have enabled the world's biggest space station to be built. The International Space Station orbits 350 kilometres above our heads, hurtling around the Earth at almost 30,000 kilometres an hour. It is one of the greatest engineering feats of all time. Its crew performs vital experiments that will one day allow humans to live permanently in space. A test bed for future missions deeper into space, the space station could enable future generations to journey throughout the Solar System or even live on Mars. Five landmark space stations contributed innovations to allow engineers to build bigger, making it possible to explore the wonders of space travel and push the boundaries of science ever farther.
