Into the Space Debris Swamp
30/04/2026 | 49 mins.
Izzie & Dr Becky think that space needs a spring clean, so this episode is all about space debris. What is it? How big of a problem is it? And what is being done to remove it?

With thanks to PhD student Megan Perks from the University of Southampton, who studies how safe all these new satellite constellations are, and photographer Max Alexander, who has created an exhibition all about space debris. It’s called Our Fragile Space and it’s on for free outside of the Royal Astronomical Society until 10th May 2026.
