SpaceX intentionally de-orbited 260 Starlink satellites between December 2025 and May 2026, according to a report submitted to the Federal Communications Commission (FCC). This figure marks an increase from the 218 satellites vaporized during the previous six-month period. In total, 1,344 Starlink satellites have undergone atmospheric re-entry, sparking debate over potential environmental impacts as the constellation expands.
Why Are Starlink Satellites Being Burned Up?
SpaceX systematically refreshes its constellation because Starlink satellites are designed to function for approximately five years. As older units reach the end of their operational lifespan, the company sends them into the atmosphere to burn up, preventing them from becoming long-term space debris.
According to the company’s recent filing with the FCC, the 260 satellites removed in the latest cycle included 176 first-generation models and 84 second-generation units. An additional 349 satellites were flagged for disposal during the same period, indicating that the pace of de-orbiting is likely to remain high as the constellation grows toward its 10,000-satellite scale.
At the peak of its de-orbiting activity between December 2024 and May 2025, SpaceX retired as many as four or five satellites per day, totaling 472 units in that six-month window.
What Are the Environmental Concerns?
The rapid disposal of thousands of satellites has prompted researchers to call for further investigation into the chemical byproducts of atmospheric re-entry. Astronomer Jonathan McDowell has tracked the disposal process, noting that the sheer volume of vaporized metal and equipment could potentially release ozone-depleting gases into the upper atmosphere.
While industry proponents argue the incineration process is clean and poses no direct threat to people on the ground, some scientific groups are urging the U.S. government to conduct a formal environmental review. Currently, the FCC has sought to exempt large satellite constellations from these specific assessments, framing the decision as a priority for maintaining U.S. dominance in the space sector.
How Does Disposal Volume Compare Over Time?
Data provided in recent FCC filings shows a fluctuating but generally upward trend in satellite turnover:
- December 2024 ā May 2025: 472 satellites de-orbited.
- June 2025 ā November 2025: 218 satellites de-orbited.
- December 2025 ā May 2026: 260 satellites de-orbited.
The disparity between the 2024ā2025 high and the subsequent periods suggests that SpaceX manages its de-orbiting schedule based on both satellite health and the deployment of newer, more capable hardware.

Frequently Asked Questions
Do falling satellites pose a danger to people on Earth?
No. SpaceX reports that its satellites are designed to incinerate completely during atmospheric re-entry, meaning they do not reach the surface.
How many Starlink satellites are currently in orbit?
The constellation has grown to include over 10,000 deployed satellites, according to industry data.
Why is the FCC considering an environmental exemption?
The regulator is prioritizing U.S. space dominance and the rapid expansion of satellite internet infrastructure, which influences how it evaluates the environmental impact of large-scale constellation management.
