SUMMARY

Spaceo develops innovative solutions to accelerate the deorbiting of end-of-life satellites, ensuring a safer and more sustainable space environment. The technology includes a rigid inflatable device to generate drag and significantly accelerate satellite deorbiting, increasing orbital cleanup speed by up to ten times. Our expert team also offers comprehensive engineering services to meet the needs of the space industry. Spaceo is incubated by the European Space Agency (ESA) and backed by Portugal Ventures.

PROBLEM

The rapid expansion of commercial constellations is driving orbital congestion to a critical tipping point. Low Earth Orbit (LEO) is increasingly cluttered with defunct hardware, creating an escalating risk of catastrophic collisions that threaten active space missions and vital global infrastructure.

Current end-of-life disposal methods are too slow, often leaving satellites adrift for decades. Furthermore, traditional active debris removal solutions are economically unviable and technically complex to scale.

As regulatory bodies enforce stricter deorbiting timelines, the space industry urgently requires a fast, cost-effective, and reliable passive technology to clear orbital paths and safeguard the long-term sustainability of space operations.

SOLUTION

Spaceo provides a highly efficient, passive deorbiting system integrated directly into the satellite before launch.

• End-of-Life Activation: Once a satellite reaches its end-of-life or suffers a critical failure, the system is triggered via a simple, ultra-reliable mechanism (such as a restriction pin or fuse wire).
• Autonomous Deployment: Upon activation, the system deploys a rigid inflatable device without relying on complex, heavy on-board propulsion.
• Aerodynamic Drag Generation: This deployed structure significantly increases the satellite's surface area, utilizing the residual atmospheric density in Low Earth Orbit (LEO) to generate passive aerodynamic drag.
• Accelerated Re-entry: The drag forces act as a continuous brake, rapidly decaying the altitude and forcing the satellite into a controlled atmospheric re-entry where it safely burns up.
• 10x Faster Orbital Cleanup: By accelerating the natural decay process up to tenfold, we dramatically reduce the time a defunct satellite spends drifting as dangerous debris.
• Drastic Cost & Complexity Reduction: Replacing traditional, expensive Active Debris Removal (ADR) systems or heavy Hold-Down and Release Mechanisms (HDRMs) with our lightweight, spring-actuated architecture cuts both manufacturing costs and launch mass.
• Immediate Risk Mitigation: Swiftly clearing orbital slots slashes the probability of catastrophic "Kessler Syndrome" collisions, safeguarding active constellations and critical space infrastructure.
• Effortless Regulatory Compliance: Our solution empowers satellite operators to seamlessly comply with strict, evolving international space debris mitigation mandates without sacrificing their payload budget.
