What Happened to the Night Sky?
SpaceX’s Starlink fleet and new commercial launches have pushed the number of satellites in low Earth orbit to 15,000, scientists and advocates say.
During a 20-minute walk in Denver two months ago, a resident observed seven satellites crossing the night sky, a dramatic shift from the 1990s when spotting even one satellite was rare.
Today, 15,000 satellites orbit Earth, up from fewer than 1,000 in the 1990s, with SpaceX owning 10,000 Starlink satellites—more than 60% of the total, according to Scientific American.
Mike Pach, secretary of DarkSky Colorado, expressed 'grave concerns' about the proposals, stressing the number of satellites being proposed will 'forever change humanity's relationship with the night sky.'
Amazon announced an $11 billion deal this month with Globalstar to launch thousands more satellites, while SpaceX has proposed to the FCC deploying one million additional satellites.
A 2021 study in The Astronomical Journal predicted 65,000 satellites would account for one in 15 visible light points in the sky, though no studies predict the visual impact of one million.
