| 7/29/25 | Astronauts. Do we need them? | It’s a brave question to put to three astronauts live on stage but it’s a risk we are prepared to take. Recorded in front of a live audience at the UK Space Conference in Manchester, European Space Agency astronauts Tim Peake, Meganne Christian and John McFall discuss the future of human space exploration. Could robots or AI take their place? Will a trip to the Moon be as common as flying across the Atlantic? And can humans be trusted to not mess with Mars? Host Izzie Clarke asks the big questions, producer Richard Hollingham threatens the audience, and (soft sceptic) Dr Robert Massey is prepared to be unpopular as they contemplate the role of astronauts in the 21st century.
