Engineers Debate

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

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.

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.
