SpaceX recently submitted its semi-annual report to the Federal Communications Commission (FCC), revealing that the company deorbited 260 Starlink satellites between December 2025 and May 2026 — 176 first-generation units and 84 of its larger second-generation V2 Mini satellites. While that number might sound alarming, the company says this is well within normal operations for a constellation of its size.
A Routine Operation, Not a Cause for Alarm
According to the FCC filing, 260 deorbits over six months isn’t unusual for SpaceX. In fact, the company deorbited 406 satellites in 2024 after identifying a common failure-risk issue in a small population of version-one satellites, and followed that with nearly 500 satellites between December 2024 and May 2025.
“Controlled, propulsive deorbit is much shorter and safer than a comparable uncontrolled, ballistic deorbit from an equivalent altitude,” SpaceX explained in its filing. The approach allows all Starlink satellites to maintain maneuverability and collision avoidance capabilities throughout their descent.
Starlink satellites are designed to burn up upon re-entering Earth’s atmosphere, and SpaceX typically targets open ocean areas away from populated islands and heavy air or maritime traffic to prevent accidents. To ensure precision, the company maintains attitude control down to very low altitudes of around 125 km.
The Growing Mega-Constellation
According to satellite tracking platform Orbital Radar, there are currently more than 9,500 active Starlink satellites in orbit, providing internet coverage to remote locations worldwide. And that number is only going up.
SpaceX recently filed an application with the FCC to launch a million satellites to create an orbital data center for SpaceXAI, the company’s AI initiative.
Earlier this year, Michael Nicolls, VP for Starlink Engineering at SpaceX, announced that the company is lowering the orbit of all satellites currently flying at around 550 km to 480 km throughout 2026. This reduces the aggregate likelihood of collision and makes it faster to deorbit satellites when needed. Elon Musk added that the lower orbit will also allow Starlink to serve a higher density of customers.
The Environmental Question
While the deorbits themselves are routine, scientists are increasingly focused on what happens when thousands of satellites burn up in the atmosphere over time.
As the Harvard Climate Brief explains, when satellite materials like carbon-fiber composites burn up, they release black carbon particles, or soot. The aluminum used in satellite construction can also turn into aluminum oxide particles, which could convert ambient chlorine into its highly reactive form.
“Chlorine is one of the key actors in the ozone hole,” said John Dykema, an applied physicist at Harvard School of Engineering and Applied Sciences. He warned that if aluminum oxide continues to accumulate in the atmosphere due to more frequent satellite deorbits, it could slow our ozone layer’s recovery.
FCC Regulations and Industry Standards
It’s also worth noting that the FCC adopted a rule in 2022 requiring Low Earth Orbit satellite operators to deorbit their satellites within five years of mission completion to reduce orbital debris. SpaceX’s own Commitment to Space Sustainability notes that its satellites orbit below 600 km, where atmospheric drag naturally deorbits them within five years anyway.
As the satellite broadband industry grows — with competitors like Amazon’s Leo service also building mega-constellations — controlled deorbits will only become more common. For now, SpaceX maintains that its approach is safe, responsible, and well within regulatory requirements.
