Space debris, also known as orbital debris or space junk, refers to any non-functional, human-made object orbiting Earth. This includes defunct satellites, spent rocket stages, fragments from past collisions, and even tiny particles like paint flecks. While many of these objects are small, they travel at speeds exceeding 17,000 mph, making even a millimeter-sized fragment capable of damaging or destroying active spacecraft. As the number of satellites in Low Earth Orbit (LEO) continues to grow, so does the volume of debris, posing serious risks to operational missions, future launches, and the long-term sustainability of space.
As the satellite industry accelerates, so does the urgency to address space debris. With the FCC’s updated orbital debris mitigation rules now in effect, satellite operators face new compliance challenges and potentially costly consequences for failing to comply.
At The Lee Company, we understand that mission success doesn’t end at launch. Our miniature, high-reliability fluid control components are engineered to support sustainable satellite design, helping customers meet regulatory requirements while optimizing performance in space’s most demanding environments.
In late 2022, the FCC introduced a pivotal change: satellites operating in or passing through Low Earth Orbit (LEO) must now deorbit within five years of mission completion, down from the previous 25-year guideline. This rule is part of a broader push to reduce collision risks and preserve orbital access for future missions.
To comply, satellite operators must submit a detailed Orbital Debris Mitigation (ODM) Plan, including:
While the FCC’s updated 5-year deorbit rule sets a new standard in the United States, Europe is also taking decisive action to safeguard Low Earth Orbit.
The European Space Agency (ESA) and national space agencies like the French CNES and Germany’s DLR are leading efforts to define and enforce space sustainability guidelines. While not regulatory bodies like the FCC, these agencies heavily influence policy across EU member states and collaborate closely with the United Nations’ Committee on the Peaceful Uses of Outer Space (COPUOS).
Key developments in Europe include:
ESA’s Zero Debris Charter (2023): A voluntary pledge for ESA missions to leave no long-term debris in orbit by 2030. Over 40 organizations have joined.
CNES Space Operations Act (2010): France’s law requires satellites to deorbit within 25 years and submit debris mitigation plans.
EU Space Law Framework (TBD): An upcoming EU law may establish binding orbital debris rules and enforcement across member states.
ClearSpace-1 Mission (Planned for 2026): ESA’s first debris removal mission will capture and deorbit a defunct object in LEO.
Low Earth Orbit (LEO) is a finite and increasingly fragile environment. With over 14,200 satellites, 11,700 of which are still operational, and 40,000 space objects regularly tracked by Space Surveillance Networks already in orbit, the risk of collisions is no longer hypothetical, it’s a daily operational concern.
And that’s just what we can track. Based on statistical models, the estimated number of space debris objects in orbit includes:
54,000 objects larger than 10 cm (including ~9,300 active payloads)
1.2 million objects between 1–10 cm
140 million objects between 1 mm–1 cm
