Episode notes
Satellite Numbers Exploding
- The number of satellites has grown tenfold in the last decade, with 11,000 operational today.
- Commercial enterprises, especially SpaceX, now dominate satellite deployment, not just superpowers.
Growing Space Collision Risks
- Space collision risks have increased, highlighted by a 2009 collision creating thousands of hazardous debris pieces.
- Satellites actively perform thousands of avoidance maneuvers to reduce risk among a crowded space environment.
Re-entry Rate Projection
- Estimated re-entry rate of satellites extrapolates to more than one falling back every hour by 2030.
- This projection depends heavily on whether 100,000 satellites actually launch and their lifespan.
