How bad are satellite megaconstellations for astronomy?


Over the last number of years, our planet has become encircled by Starlink, OneWeb, and other “megaconstellation” satellites. Yes, the emergence of those megaconstellations offers great benefit for humanity.

“Some astronomers see this as a true ‘hair on fire’ emergency, heralding irretrievable losses to space science; others present a more sanguine face, depicting this as yet another challenge to be surmounted in surveying a decreasingly pristine sky,” Koplow remarks. That said, the astronomical community has related that the time and the financial costs of conducting effective astronomy will rise considerably, Koplow says, “and that some important data will simply be irretrievable, with concomitant losses for science and the future exploration and use of space.” In his “Blinded by the Light” treatise, Koplow describes the incipient clash between satellite megaconstellations and astronomy, assesses the relevant international and domestic legal authorities, and proposes compromise solutions to mitigate the damage.
