United in space: How we built the ISS

Celebrating 25 unbroken years of humans living in space, former international director of the UK Space Agency Dr Alice Bunn charts how nations put aside differences to create the ultimate symbol of human ingenuity and collaboration – a space station orbiting our planet that has been home to more than 300 people from 24 different nations.

Using mission control audio, news archive and personal stories, Alice illuminates acts of epic survival, humour and selflessness that made the station a reality. She investigates why a near fatal disaster on the Russian Mir space station spurred nations to commit to the ISS, and reveals how a Moscow basement and Hollywood royalty sparked bonding between Russians and Americans. She also discovers how quick thinking and plastic tape saved the station, allowing it to grow to the size of a football pitch, and how one astronaut came within seconds of drowning in space.

Looking into the future, Alice explores how the legacy of the ISS will be carried on by a new generation of private space stations, which have the power to push back the boundaries of science for the good of all humanity. The reduced gravity offers enormous possibilities, including creating materials impossible to create on Earth.
