SpaceX burned up 260 Starlink satellites in six months, with hundreds more waiting

SpaceX has confirmed that 260 Starlink satellites were deliberately de-orbited and burned up in Earth’s atmosphere between December 2025 and May 2026, according to a report submitted to the Federal Communications Commission (FCC).The satellites were guided back into the atmosphere through controlled manoeuvres using onboard propulsion systems. Once they reached denser layers of air, the spacecraft disintegrated under extreme heat and friction. SpaceX said the process ensured complete destruction, leaving no debris on the ground.Of the 260 satellites, 176 belonged to the first-generation Starlink network, with the remainder drawn from second-generation spacecraft.

A further 349 satellites were also taken out of service during the same six-month period and are expected to undergo disposal in the coming months.The latest figures show a slight increase from the previous reporting period, when 218 satellites were de-orbited between June and November 2025.

A fast-moving cycle inside a vast satellite network

Starlink has grown into one of the largest satellite constellations ever deployed, with more than 10,000 spacecraft currently in low Earth orbit.

The system is designed around rapid replacement, with each satellite expected to operate for about five years before being retired.As fuel runs low or systems age, satellites are programmed to lower their altitude and re-enter Earth’s atmosphere. The descent is controlled to ensure they burn up completely rather than remain as long-term space debris.SpaceX has described this approach as part of routine fleet management.

The company says retrieving satellites is not practical due to their altitude, cost, and the scale of the constellation.At present, the company is de-orbiting multiple satellites every day as part of ongoing maintenance of the network. According to astronomer Jonathan McDowell, at least 1,344 Starlink satellites have already re-entered the atmosphere since the system began scaling up in recent years.

Lifespan design and continuous replacement

The satellites are built with a limited operational lifespan.

Most Starlink units are expected to function for around five years before they are replaced with newer models offering improved bandwidth, power efficiency and communication capabilities.Once a satellite reaches the end of its mission, it uses remaining fuel to gradually drop out of orbit. This controlled descent is intended to prevent uncontrolled break-up and to reduce the risk of debris remaining in space.SpaceX’s filings suggest that the majority of retired satellites are de-orbited within months of receiving their final command, reflecting a tightly managed replacement system.The company is also expanding the constellation further, with approvals for thousands of additional second-generation satellites. Long-term plans envision up to 42,000 satellites in orbit to support global broadband coverage and emerging services such as direct-to-mobile connectivity.

Concerns over atmospheric effects

While SpaceX claims that its satellites completely burn up during re-entry, the scale of repeated atmospheric destruction has raised questions among researchers about what happens to the material that does not return to Earth, the material which is left behind.When satellites disintegrate, their metal components, particularly aluminium structures, are converted into fine particles such as aluminium oxide.

These particles are released into the upper atmosphere at high altitudes.The accumulation of these materials, especially if thousands of satellites are de-orbited over time, could alter the chemistry of the upper atmosphere. Potential risks discussed in academic circles include changes to how sunlight is absorbed and possible effects on the ozone layer, although long-term impacts remain uncertain.The rapid growth of satellite megaconstellations in the space has intensified calls for more detailed environmental assessments.

The cumulative effect of constant satellite burn-ups has not been fully studied at scale, particularly as multiple rival companies expand their fleets alongside Starlink.

Regulatory debate in Washington

The regulatory framework governing satellite launches and de-orbits in the United States is now under scrutiny.The FCC, which oversees licensing for satellite constellations, has historically excluded space-based operations from full environmental review requirements under the National Environmental Policy Act (NEPA).

The reasoning has been that orbital activities occur outside US territory.A new proposal under consideration would formally exclude space-based operations from NEPA environmental assessments, classifying them as extraterritorial activities with effects outside US jurisdiction.If adopted, the change would mean companies like SpaceX would not be required to conduct detailed environmental impact statements focused on upper-atmospheric effects before expanding large satellite fleets.Supporters of the proposal argue it would streamline approvals and support rapid technological development. Critics say it risks overlooking environmental impacts that occur beyond traditional national boundaries but still affect the planet.

Rapid expansion alongside disposal cycles

Despite the steady retirement of older satellites, Starlink continues to expand at speed. SpaceX has already secured approval for thousands of additional second-generation satellites and continues launching new batches regularly using Falcon 9 rockets.The company is also developing newer spacecraft designs that are larger and more capable than earlier versions. These updated satellites are intended to support higher data capacity and improved global coverage.SpaceX has also outlined future systems involving orbital computing infrastructure, where satellites would process data directly in space rather than relying solely on ground-based systems. These developments point towards a broader shift in how satellite networks are used, moving beyond internet connectivity into more complex data handling roles.At the same time, older satellites are being cycled out at a steady pace, creating a continuous loop of launch, operation and atmospheric disposal.

A growing presence in Earth’s upper atmosphere

With thousands of satellites already in orbit and tens of thousands more planned, controlled re-entry has become a routine part of Starlink operations.Each de-orbit event ends with a satellite burning up high above Earth, a process SpaceX says is safe and contained. But as the number of satellites increases, so does the total material entering the atmosphere through repeated burn-ups.Starlink is a satellite internet network developed by SpaceX, the private aerospace company founded by Elon Musk in 2002. Musk set up SpaceX with the goal of reducing the cost of space travel and building technologies that could support life beyond Earth. Starlink later emerged as one of the company’s major projects, designed to use large numbers of low Earth orbit satellites to deliver broadband internet coverage across the world, especially in remote and underserved regions like Alaska and even Antarctica.

The system began deployment in 2019 and has since expanded into one of the largest satellite constellations in operation.
