7am Why Elon’s million satellites could spell disaster
Feb 22, 2026
Samantha Lawler, Associate Professor of Astronomy who studies orbital dynamics and space debris. She discusses SpaceX’s plan for up to a million satellites and whether orbiting data centres are viable. She talks about falling debris hitting her hometown, the visual impact on night skies, collision cascade risks like Kessler syndrome, and gaps in current space regulation.

Episode notes
Starlink Scale Is Already Massive
- Starlink already has nearly 10,000 satellites in orbit and has launched over 11,000 so far.
- SpaceX plans up to one million satellites, which would be many orders of magnitude more than current constellations and radically change orbital density.
Space Data Centers Face Hard Cooling Challenges
- SpaceX pitches orbital data centers as greener because cooling is easier in space and solar power is abundant.
- Samantha Lawler warns dissipating heat in vacuum is actually hard and earlier darkened Starlink hardware overheated and fried when tested.
Burnup Pollution From Mass Satellite Deorbiting
- Satellites are large and burn up in Earth's atmosphere at end-of-life, depositing electronics and materials into upper atmosphere.
- Lawler compares Starlink satellites to 'a Ford Ranger with 30 meter solar panels' and warns a million burning up would be catastrophic.
