Once you’ve been in space, you appreciate how small and fragile the Earth is. Over 20 years ago, rival nations put aside political and cultural differences to come together in a demonstration of international co-operation to create something unique – the International Space Station.

Drawing together personal stories from men and women from around the world who have been a part of this extraordinary endeavour, the film provides a fascinating insight into human nature and our relationship with planet Earth and space – the great unknown.
