Join us for an audience with Tim Peake in the UK’s largest planetarium. He will share insights from his Principia mission and reflect on life and work in the decade since returning to Earth.

Tim Peake
In May 2009 Tim Peake was selected as an ESA astronaut and after arduous training he was assigned to a mission to the International Space Station in May 2013. After many months spent in Russia learning how to operate the Soyuz spacecraft, he launched to space on 15 December 2015.
During his Principia mission Tim took part in over 250 scientific experiments. He conducted a spacewalk to repair the Station’s power supply, drove a rover across a simulated Mars terrain and helped dock two spacecraft. He was also actively connected with the public back on Earth – his mission focused on educational outreach, engaging more than 2 million schoolchildren across Europe in over 30 projects during his time in space.
