The number of satellites has grown dramatically and it will continue to grow. But where's the limit? How many satellites can we realistically launch? Most people think that it's the Kessler Syndrome. Saturating the orbit with space debris until a chain reaction erupts. But there might be other limiting factors. What are they? Finding out in this interview.
