Highlights

  • Current policy does not reflect current trends in the space field, legally and economically.
  • Hazards to satellites arise from environmental and anthropogenic sources.
  • Without adequate preparation, these hazards threaten the sustainability of Low Earth Orbit.
  • Preventative policy can address these hazards before they become an issue as the Low Earth Orbit economy surges in the coming decade.

Article Summary

Satellites in the Low Earth Orbit (LEO) environment face various hazards which threaten the long-term sustainability of the space economy. This article describes the potential dangers to satellites in LEO beyond commonly referenced orbital debris and satellite collisions, including hazards that arise from the LEO environment itself and from other anthropogenic sources such as laser interference and orbital light pollution. As the LEO economy surges in the coming decade, preventative policy such as that proposed in this article could address these risks before they become an issue and ensure that the LEO environment continues to grow sustainably.
