Big Sky – How Safe is Space?

Sustainable Use of Space – On-Orbit Servicing and Orbital Debris Mitigation


  • The volume of space inside Geosynchronous Orbit is ~76 trillion cubic miles
  • 11 Countries have launch capability today:– China, France, India, Iran, Israel, Japan, North Korea, Russia, South Korea, Ukraine, United States–Over 100 nations have operating satellites
  • Inter-Agency Space Debris Coordination Committee (IADC), 50th Session of the Scientific and Technical Sub-Committee to the Committee on the Peaceful Uses of Outer Space (COPUOS)
  • –“The debris situation in low Earth orbit (LEO) may be reaching a catastrophic tipping point, known as the Kessler Effect, predicted by Donald Kessler from NASA in 1978.”–Collisions between objects will cause a cascade of collisions, increasing the likelihood of further collisions.–“Could render space activities in LEO impossible for several generations.”
