What's it like living underwater for two weeks? What's the trickiest part of training to be an astronaut? What are the most memorable sights you see from space?

After a childhood packed with outdoor adventures, via the Cub Scouts and school Cadet Force, Tim joined the British Army Air Corps and became a military flying instructor then a test pilot; before eventually being selected as a European Space Agency (ESA) astronaut.

In 2015, Tim became the first British ESA astronaut to visit the International Space Station. Over the course of a six-month mission, he took part in more than 250 scientific experiments and worked with more than two million schoolchildren across Europe.

In a special New Year’s episode recorded in front of an audience at London’s Royal Society, Professor Jim Al-Khalili talks to Tim about his lifelong passion for adventure, the thrill of flight and why scientific experiments in space are so important.
