Impact of Satellites on Radio Astronomy— Science News, October 5, 1974
Two major U.S. satellites launched in May have been causing disruptions in radio astronomy research. The presence of these satellites along the line of sight between an observer and their subject makes it challenging or even impossible to conduct studies. While a few interlopers may be manageable, a large number would spell disaster for radio astronomy.
The situation has worsened over time as private companies have flooded Earth’s orbit with thousands of new satellites since 2019, surpassing astronomers’ worst predictions from the ’70s. With over 10,000 active satellites currently in orbit and more being launched regularly, astronomers fear an impending catastrophe is on the horizon due to the increased radiation emissions from modern satellites (SN: 9/30/24). Not only are radio telescopes affected but optical telescopes as well, with bright streaks marring images of the night sky and hindering analysis efforts. Attempts to address this issue through satellite modifications or changes in orbits have yielded mixed results (SN: 10/9/21 & 10/23/21, p.14).
