Episode 401 - Space Collisions and cleaning up debris

October 19, 2020

Dodging collisions faster than a speeding bullet. We look at cleaning up space debris. Explosions and collisions of spaceships is great in sci-fi but bad news for us on Earth. Space is rapidly filling with satellites. What happens to them at the end of their life? Collisions in space (or near misses) are becoming more and more common. How can we clean up space and keep the skies safe for important satellites.
