Are we alone in the universe? How did our solar system evolve? These are the kind of questions that inspire John Zarnecki, Professor of Space Science in the Department of Physics and Astronomy at The Open University. In the course of his 30 year career, Zarnecki has taken part in several high profile space probe missions. In this album, he recalls the landing of the Huygens probe on Titan, explains why space has become essential for communication and navigation today and describes technology developed by the space programme that's set to improve our lives on Earth.
