If you follow news about satellites, you have probably seen references to the FCC's "5-year rule." It sounds like fine print, and in a way it is. But it is also one of the first binding rules anywhere about what happens to a satellite after its working life is over, and it says a lot about how the thinking on orbital debris has changed.

This page is a plain-English explainer. It covers what the rule says, who it applies to, how it replaced the older 25-year guideline, and, just as important, what it does not cover. At the end there is a short, modest note on where a debris removal concept like The Incognito might fit. We have tried to stick closely to what the Federal Communications Commission actually wrote, and we link to the documents so you can check us.

What the rule says

On September 29, 2022, the FCC adopted a Second Report and Order in a proceeding titled "Space Innovation; Mitigation of Orbital Debris in the New Space Age" (FCC 22-74). The FCC's news release that day summed it up in one sentence: the new rules require satellite operators in low Earth orbit to dispose of their satellites within 5 years of completing their missions.

The order itself is more precise. It requires space stations ending their mission in, or passing through, the low Earth orbit region below 2,000 kilometers altitude, and planning disposal through uncontrolled atmospheric re-entry, to complete disposal "as soon as practicable" after the end of the mission, and no later than five years after it.

Two details in that wording are worth slowing down on.

  • "As soon as practicable" comes first. Five years is the outer limit, not the target. The wording asks operators to finish disposal sooner whenever that is practicable.
  • "End of mission" has a specific meaning. The order defines it as the time when the individual spacecraft is no longer capable of conducting collision avoidance maneuvers. For a spacecraft that never had that capability, end of mission is when it has completed its primary mission, such as providing communications or remote sensing.

The FCC also chose not to tell operators how to get rid of their satellites. The order says it declined to prescribe a specific method of post-mission disposal, keeping the rule performance-based so it can fit different technologies and mission profiles.

Who it applies to

The FCC licenses the radio communications that satellites depend on, and that is the hook for this rule. According to the order, the requirement applies to:

  • U.S.-licensed satellites ending their mission in, or passing through, low Earth orbit (including, per a footnote in the order, satellites in elliptical orbits whose lowest point dips into that region);
  • operators seeking access to the U.S. market with a satellite licensed by another country;
  • small satellites licensed under the FCC's streamlined small-satellite process;
  • experimental satellites licensed under Part 5 of the FCC's rules; and
  • amateur satellites authorized under Part 97.

The order also included a transition period. Satellites already in orbit were exempted from the new requirement. Satellites that were already authorized but not yet launched received a two-year grandfathering period beginning September 29, 2022. New licensees and existing applicants with authorized satellites launched after September 29, 2024, must comply with the five-year requirement, though the FCC said it would consider waivers in individual cases.

On waivers more generally, the FCC did not grant blanket exceptions. It said operators could seek a waiver for good cause if a satellite failure or anomaly led to non-compliance, but noted that "such waivers will not be liberally granted." It also said it would treat academic and scientific research missions as a special category when weighing waiver requests, without exempting them outright.

How it changed the old 25-year guideline

For decades, the common benchmark was 25 years. The order explains that the 25-year disposal guideline was first proposed by NASA in the 1990s, as a balance between limiting debris and limiting the fuel cost and complexity of lowering a satellite's orbit. It was later adopted by other nations' space agencies and the Inter-Agency Space Debris Coordination Committee, and written into U.S. government standard practices. But it was a guideline, not a law. The order notes that the existing orbital debris guidelines were not legally binding, and that the FCC had consistently applied the 25-year benchmark in licensing decisions even though it was not specifically written into the FCC's 2004 debris rules.

The FCC's reasoning for shortening it was direct. "We believe it is no longer sustainable to leave satellites in LEO to deorbit over decades," the order says. It observed that the 25-year benchmark was developed before large satellite constellations were proposed, and is "too long to adequately address the threat of long-term debris generation."

The FCC also recorded the other side of the debate. Some commenters argued the 25-year standard was still effective, and many of them pointed to a NASA Orbital Debris Program Office report finding that moving from 25 to five years would reduce debris by 10% over 200 years, which NASA described as "not a statistically significant benefit." Other commenters responded that the analysis did not fully capture the risk of leaving dead satellites in lower orbits for up to 25 years, including more collision-avoidance maneuvers for working satellites. The FCC found those arguments persuasive. One comment it repeated gives a feel for the scale: for typical low Earth orbit satellites, 25 years represents five generations of spacecraft and 135,000 uncontrolled orbits.

The FCC's news release called the result "the first concrete rule on this topic, replacing a long-standing guideline." The same idea has spread elsewhere. The European Space Agency, for example, reports that it adopted its own tightened standard of vacating orbits within five years for its own activities in 2023.

What the rule does not cover

This is the part that tends to get lost in headlines. The 5-year rule is about the future. It shapes how new satellites are planned and licensed. It does not clean up what is already up there.

  • Satellites already in orbit are exempt. The order says so plainly. A dead satellite that was launched before the rule took effect is not required to come down within five years.
  • It does not reach the old hardware already circling Earth. The rule is written for space stations, the FCC's term for radio stations on objects in space, that come before the FCC for authorization. Large derelicts launched years or decades ago, including the "discarded rocket cores" that the FCC itself listed alongside defunct satellites as debris now filling the space environment, are not covered by it.
  • It applies only to disposal by uncontrolled re-entry below 2,000 km. The text of the rule is limited to low Earth orbit space stations planning that kind of disposal.
  • It leaves some questions for later. The order says topics such as maneuverability, accidental explosion risk, and collision risks from large constellations would be addressed at a later date. It also said the FCC would keep assessing whether an even shorter period, such as one year, might be appropriate for large constellations.

In other words, the rule helps keep the problem from growing as fast. It does not shrink the problem. ESA's 2025 Space Environment Report makes the same broader point in its own words: "not adding new debris is no longer enough: the space debris environment has to be actively cleaned up." ESA also notes that satellites left in their operational orbit at the end of their mission are at risk of fragmenting into clouds of debris that linger for many years. Our guide to Kessler syndrome explains why that chain reaction matters.

Where a removal service like The Incognito might fit

The Incognito is John Arwood's idea for a garbage truck in the sky: a self-sustaining orbital spacecraft concept for collecting and disposing of debris. It is a concept, not a flying prototype, and the design is patent pending.

As described on The Concept, the craft would use ion thrusters for efficient in-space travel, with an onboard nuclear reactor as its main power source and solar cells around the exterior as backup. It is meant to haul large debris, including objects larger than its own body, with thrusters across its exterior for the agility to approach uncooperative objects and modular add-ons for different jobs. The proposed sequence is simple: launch on a conventional rocket, travel to a target, capture it, and lower its orbit so it burns up in the atmosphere, then move on to the next object.

That is a different job from the one the FCC rule addresses. The rule asks operators to plan their own satellites' exits. A removal service would go after the objects that nobody is required to bring down: the large, dead hardware already in orbit. We do not claim The Incognito is the answer, or the only answer. ESA describes active debris removal demonstrations in development, and others are working on this too. It is one proposal, from someone who has spent a working life hauling material away so places stay usable.

Frequently asked questions

Does the FCC 5-year rule require satellites already in orbit to come down?

No. The order says satellites already in orbit are exempt. The rule applies to satellites launched after the transition period, which ended September 29, 2024, with possible case-by-case waivers.

Does the rule apply to non-U.S. satellites?

It applies to operators seeking access to the U.S. market using a satellite licensed by another country, consistent with the FCC's other satellite rules.

Is five years the deadline or the goal?

The deadline. The rule requires disposal "as soon as practicable" after the end of the mission, and no later than five years.

Does the rule cover old rocket bodies?

No. The rule applies to space stations seeking FCC authorization, and nothing in it requires removal of spent rocket stages or other derelicts already in orbit. Dealing with those would take active removal of some kind.
