    Two Engineers Debate Who Should Clean Up Space Debris. They Didn't Get to Pick Their Sides

    Should governments pay to clean up the junk already in orbit?We argue it over three points:1. Who made the mess?2. Who's paying for it now?3. Is this the industrial revolution again?Which side won? Tell us in the comments, and tell us if you changed your mind by the end. Gigi argued governments should pay, then dropped the act and said what he really thinks.Gigi: space systems engineerSam: space missions, operations and FDIR engineerCORRECTIONS1. 07:45 - Kosmos 954 crashed in Canada in January 1978. Canada filed its claim against the USSR in January 1979, not 1978.2. 29:17 - Context: small debris is the bigger collision risk, but removal missions target large objects, because those break up into more small debris.3. 34:36 - €86m was ESA's price to remove one object (ClearSpace-1), not 86 billion. Clearing the 2,000–3,000 worst objects is estimated at tens of billions.4. 35:59 - It wasn't "99% government launches" before 2010. Commercial TV satellites flew for decades, and Iridium and Globalstar launched in the late 1990s.CHAPTERS00:00 Cold open00:36 355,000 dodges, and no law to clean it up01:19 Spinning the wheel01:53 Who we are, and which side we wanted03:31 The facts: what's up there, and who put it there05:48 The facts: what it costs, and who's liable09:05 The three Points09:34 Point 1: Who made the mess?11:40 Sam: it's about who's able to clean it up14:48 Gigi's concession: the CMOS sensor16:47 Point 2: Who's paying for it now?20:04 The car park analogy21:31 "The company pays taxes"25:30 Point 3: Is this the industrial revolution again?28:42 Sam: "subsidise" is the key word32:20 Towards a hybrid model33:10 Dropping the act: what we actually thinkDISCLAIMERThe views and opinions expressed in this video are those of the hosts and guests, speaking in a personal capacity.

    Do We Need Humans on the Moon? Neither of Us Picked a Side

    Multiple nations are heading for the same few square kilometres of the lunar south pole. The US is proposing to cancel a third of NASA's future science missions to help pay for a base on the Moon, and one of us has to defend that decision. Every episode, we take randomly assigned opposite sides of a motion, debate it, and then drop the act and say what we actually think. Today's motion: should we build a permanent human base on the Moon, and should we do it now? Gigi argues AGAINST building a Moon base and Sam drew FOR. Neither of us picked. We argue it over three points: 1. Whoever gets there writes the rules 2. The whole case rests on water ice nobody has touched 3. This is the same space race we ran 50 years ago, and it may end the same way Listening without the video? Watch the full debate, with the on-screen figures, on YouTube: https://www.youtube.com/watch?v=gSBO6xDjiY0 Which side did you land on? Tell us in the comments on Spotify or YouTube. CORRECTIONS 1. At 05:45: Russia's failed lunar lander was Luna 25, which crashed in August 2023. "Luna 3" was the 1959 far-side photographic mission. 2. At 12:20: The vehicle that exploded on the pad at Launch Complex 36 in May 2026 was a New Glenn rocket during a static fire test, not the Blue Moon Mk1 lander. The Mk1 has not flown yet. 3. At 23:50: NASA revived VIPER with a Blue Origin CLPS task order in September 2025, not May. In May 2025, NASA had announced it would not pursue a commercial partnership for VIPER.

    Two Engineers Debate Starship. Neither Picked Their Side

    SpaceX's Starship is either the most important vehicle in spaceflight history or an expensive detour. We didn't get to choose which side we argued. Recorded before Starship flight 14. Every episode we're assigned FOR or AGAINST at random, argue it as hard as we can, then drop the assignment and say what we actually think. This one covers payload economics, the refuelling architecture, the HLS timeline, and whether full reusability changes the maths or just moves the cost around. Listening without the video? Watch the full debate, with the on-screen figures, on YouTube: https://www.youtube.com/watch?v=_ENywaUKrDA Which side did you land on? Tell us in the comments on Spotify or YouTube. Gigi and Sam are engineers working in the space industry.
