Astronauts. Do we need them?

Astronauts. Do we need them?

Author: The Royal Astronomical Society July 30, 2025 Duration: 50:04

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.

Hosted by science journalist Izzie Clarke and astrophysicist Dr. Becky Smethurst, The Supermassive Podcast is a journey through the cosmos produced by The Royal Astronomical Society. Each episode blends cutting-edge science with historical context, creating a rich narrative that connects past discoveries to present-day mysteries. You’ll hear conversations with leading researchers breaking down complex ideas, from gravitational slingshots to the nature of time itself, alongside deep dives into archival material that reveals how our understanding of the universe has evolved. The tone is both curious and conversational, making even the most profound concepts in physics and astronomy feel accessible and exciting. Regular contributions from Dr. Robert Massey offer practical guidance for observing the night sky, grounding the theoretical in the tangible. This isn't just a series of interviews; it's an exploration driven by listener questions, which range from the wonderfully weird to the fundamentally profound, ensuring every topic has a direct link to shared human curiosity. Tuning into this podcast feels like having a front-row seat to the latest scientific discussions while being reminded of the long, fascinating history that got us here. It’s where the biggest questions about black holes, multiverses, and our place in the cosmos are met with genuine enthusiasm and expert insight, all delivered with a distinctly engaging energy.
