On Tuesday, 25 August 2020, astronomers released the final report from the Satellite Constellations 1 (SATCON1) workshop during a virtual press conference hosted by the National Science Foundation’s NOIRLab and the American Astronomical Society (AAS).

When SpaceX began launching clusters of 60 Starlink satellites in May 2019, astronomers reacted with alarm. Not only are the Starlink satellites brighter than anyone expected, but there could be tens of thousands more like them as companies in the rapidly growing commercial space industry strive to provide satellite-based communication services to underserved and remote areas. Constellations of bright satellites in low Earth orbit will fundamentally change ground-based optical and infrared astronomy and could impact the appearance of the night sky for stargazers worldwide.

SATCON1 gathered more than 250 astronomers, satellite operators, dark-sky advocates, and other stakeholders to discuss, understand, and quantify the astronomical impacts of large satellite constellations. The workshop report features two findings, ten recommendations, and four technical summaries and was released to the public at the start of the briefing at aas.org/satellite-constellations-1-workshop-report.
