Following a rare screening of Out of the Present, Andrei Ujica's remarkable feature documenting life on the Mir space station, cosmonaut Sergei Krikalev joins Helen Sharman (the first Briton in space) to discuss the film.
As well as describing his experiences of space travel - while Krikalev was in orbit, the events of 1991 transformed Russia’s political landscape forever - he and Sharman field questions from the public. Would they be willing to be the first people on Mars if it meant they could never come back? Their answers may surprise you.
This Q&A took place as part of Red Space, the centrepiece event of our Kosmos: A Soviet Space Odyssey season.
