  The Prison Planet Problem - Exiled to Space 24.09.2026 33min

  What happens when a prison planet ceases being a prison? We explore whether penal colonies could really work, and how exile, frontier justice, rebellion, and redemption might turn punishment into civilization.

  The First Space Elevator: Where Would We Build It? (Narration Oly) 10.09.2026 22min

  A space elevator could transform access to orbit, but where should humanity build the first one? Earth, the Moon, Mars, or somewhere else entirely? We explore the physics, engineering, and best locations.
