SpaceX crosses 10,000-satellite threshold, owning two-thirds of all active satellites in orbit

SpaceX hit a landmark milestone in the early hours of Tuesday morning, pushing its Starlink internet constellation past 10,000 simultaneously active satellites, a figure that would have seemed fantastical just a decade ago.

The milestone was crossed at 1:19 a.m. EDT when a Falcon 9 rocket lifted off from Vandenberg Space Force Base in California, carrying 25 new Starlink satellites into orbit. The active constellation now stands at 10,020 satellites, according to tracking data compiled by astrophysicist Jonathan McDowell. SpaceX has launched 11,529 Starlink satellites since May 2019, with the remainder deorbited or replaced as older units wore out.

Two-thirds of the sky

Until the turn of the century, only a few hundred satellites operated in Earth’s orbit at any one time, growing to a few thousand by the 2010s. Starlink alone now accounts for roughly two-thirds of every active satellite circling the planet. The next largest constellation, Europe’s OneWeb, numbers just 654 satellites.

“Starlink has changed our relationship with space,” Hugh Lewis, a space debris expert at the University of Birmingham, told Scientific American. “The character of the night sky is no longer the same as it once was, and I’m not sure it will ever be again.”

SpaceX has been averaging a launch every 2.3 days in 2026, and, as of February, reported more than 10 million active customers across 160 countries — from rural American towns to Ukrainian battlefields. That reach grants CEO Elon Musk an unprecedented degree of geopolitical influence: the practical ability to switch internet connectivity on or off for entire regions.

Managing 10,000 objects at 17,000 mph

All those satellites orbit in a narrow band roughly 300 to 340 miles above Earth, moving at approximately 17,000 miles per hour. Keeping them from colliding requires autonomous traffic management on a scale never attempted before. SpaceX disclosed to federal regulators that its constellation performed roughly 300,000 collision avoidance maneuvers in 2025 alone, nearly 40 per satellite for the year. Before Starlink, a typical satellite might execute only a handful in its entire operational life.

The collision record so far is clean, but scientists are uneasy. If satellites did collide, the resulting debris could trigger a chain reaction that renders certain orbital altitudes unusable for years. “Our ability to keep using orbit depends on Starlink continuing to operate perfectly,” astronomer Samantha Lawler told Scientific American. “It makes me nervous, for sure.”

What comes next

Ten thousand is not the ceiling. SpaceX already has regulatory approval to expand Starlink to roughly 42,000 satellites, and this year, the company is expected to begin launching a more powerful generation of satellites aboard its massive Starship rocket. Mr. Musk has also announced plans to orbit up to one million additional satellites to serve as space-based computing centers for artificial intelligence.

Competitors remain far behind. Amazon’s Project Kuiper has launched roughly 200 of its planned 7,500 satellites, while China’s state-backed programs are targeting tens of thousands more. Five additional Starlink launches are already scheduled for next week. Earth’s orbit, empty of any human-made object as recently as 1957, is getting more crowded by the day.
