Colonel Chris Hadfield is a former fighter pilot who became an astronaut and served as a commander of the International Space Station (ISS).

While in orbit he became a social media star, posting breath-taking pictures of earth, as well as videos demonstrating practical science and playing his guitar. These days, the Canadian invests in businesses and has written several best-selling fiction and non-fiction books.

In this programme, Chris Hadfield tells Russell Padmore how he was influenced by Star Trek, and the Apollo missions to the moon, as a child. He outlines why he welcomes private investment in space and he explains how he has become known for being the musical star in orbit.
