SpaceX filed its semi-annual compliance report with the FCC earlier this month, and the numbers are worth paying attention to. Between December 1, 2025, and May 31, 2026, the company deliberately deorbited 260 Starlink satellites—steering them into the atmosphere where friction burns them up completely.
Of those, 176 were first-generation units; the rest came from the newer Gen2 fleet. Another 349 satellites were decommissioned during the same period and are now waiting in line for disposal.
To put that in perspective: at the current average deorbit rate of about 43 satellites per month, those 349 represent roughly eight months of "depletion inventory".
The Mass Retirement Is (Mostly) Over
This isn't panic territory—it's planned obsolescence. The big spike happened a year earlier, when SpaceX deorbited 472 satellites between December 2024 and May 2025. That was the peak of retiring the oldest first-generation hardware. By the following six months (June to November 2025), the number dropped to 218.
Astronomer and satellite tracker Jonathan McDowell put it simply: SpaceX has "largely completed the mass retirement of the older sats". The current 260 figure represents a slight uptick from the previous period, but nothing like the 472 peak.
The total count so far? According to McDowell's tracking data, 1,357 Starlink satellites have re-entered the atmosphere and burned up as of this writing. That's about 13% of everything SpaceX has launched.
Why So Many?
The rationale is straightforward. Each Starlink satellite is designed for about five years of service. Once the fuel runs low, the satellite uses whatever remains to perform a controlled descent. Atmospheric drag does the rest.
Retrieval isn't an option. First-generation units weigh 260 to 295 kg; second-generation satellites are 800 to 1,250 kg. Bringing them back intact is technically impractical and economically unfeasible.
SpaceX reports a disposal reliability rate above 99%, comfortably exceeding the FCC's 95% minimum standard.
The Commercial Reality Nobody's Talking About
Here's where it gets interesting. The FCC report contained another data point that Wall Street is starting to notice: V2 satellites performed 142,015 collision avoidance maneuvers within six months—more than double that of the V1 fleet.
Why does this matter? Because more maneuvers mean more fuel burn, which means shorter effective lifespans. The performance upgrades of Gen2 are being partially offset by higher operating costs. SpaceX is transitioning from infrastructure build-out to operations and maintenance—and in that phase, the core financial variable isn't new users anymore. It's depreciation and replacement costs.
The company admits that maintaining this "conservative disposal strategy"—actively deorbiting satellites ahead of schedule rather than waiting for failures—requires "significant investment".
What's Changing in 2026
A more significant shift is underway. SpaceX announced it will lower the operating altitude of about 4,400 satellites from 550 km to roughly 480 km throughout 2026. The move follows a near miss with a Chinese satellite last year.
The physics are clear: lower orbit means faster deorbit times when something goes wrong—cutting decay periods from over four years to just a few months. It also reduces collision risk, since "the number of debris objects and planned satellite constellations is significantly lower below 500km," according to Starlink's VP of Engineering.
The Unresolved Question
Not everyone is comfortable with this becoming routine. Researchers have raised concerns about what happens when thousands of satellites burn up in the atmosphere. The metals released could affect the ozone layer.
The FCC has proposed excluding space activities from National Environmental Policy Act review, arguing they're "extraterritorial activities" outside U.S. jurisdiction. That rule hasn't been finalized. If it eventually reverses, or if the international community starts attaching environmental costs to constellation deployments, that 5.7% replacement rate won't just be depreciation—it could become a hard expense.
Bottom Line
260 satellites in six months sounds dramatic. It's not. It's the cost of maintaining the largest satellite constellation ever built—over 10,000 satellites and counting. The mass retirement of first-generation hardware is largely complete. The real story isn't the burn rate. It's what comes next: lower orbits, faster deorbit times, and a growing tension between operational necessity and environmental accountability.
That's the part worth watching.
