Blinded By The Light: Resolving The Conflict Between Satellite Megaconstellations And Astronomy, David A. Koplow

Georgetown Law Faculty Publications and Other Works

The sudden emergence of large constellations of small satellites in low altitude orbits represents one of the most dramatic contemporary innovations in outer space. Promising low-cost, low-latency global communications and spectacular capacities for remote sensing of the Earth, these satellites will soon number in the tens of thousands, sponsored by diverse corporations and countries around the world. But this proliferation of spacecraft comes at a steep cost in unavoidable interference with ground-based astronomy: as the satellites overfly the observatories, they block the views of remote objects and phenomena, leaving obliterating white streaks on the collected imagery, and obscuring access to …

Who Owns The Skies? Ad Coelum, Property Rights, And State Sovereignty, Laura K. Donohue

In light of the history of the doctrine of ad coelum, as well as the states’ preeminent role (secured by the Tenth Amendment) in regulating property and airspace up to the 500-foot level, it is remarkable that the federal government has begun to claim that it controls everything above the blades of grass. This chapter challenges those statements, demonstrating that history and law establish that property owners, and the states, control the airspace adjacent to the land.

Exoatmospheric Plowshares: Using A Nuclear Explosive Device For Planetary Defense Against An Incoming Asteroid, David A. Koplow

What should be done if we suddenly discover a large asteroid on a collision course with Earth? The consequences of an impact could be enormous—scientists believe that such a strike 60 million years ago led to the extinction of the dinosaurs, and something of similar magnitude could happen again. Although no such extraterrestrial threat now looms on the horizon, astronomers concede that they cannot detect all the potentially hazardous “near-Earth objects,” and even more striking, they acknowledge that if such a danger were discerned, there is currently no proven capability for diverting or destroying it.

One possible response to this …
