Study: Rapid Development of Satellite Mega-Constellations Risks Tragedies of the Commons
A study reported in Nature, “Satellite mega-constellations create risks in Low Earth Orbit, the atmosphere and on Earth,” in Scientific Reports (May 2021) by Aaron C. Boley and Michael Byers, says the rapid development of mega-constellations risks multiple tragedies of the commons. That could include tragedies to ground-based astronomy, Earth orbit, and Earth’s upper atmosphere. The study asser...
