The passive de‑orbiting solution for a sustainable LEO.
Ultra-light inflatable drag sails that clear satellites from orbit at end of mission — no fuel, no thrusters, no mass penalty.
Orbit is filling up faster than it can clear itself.
Space junk stays for decades
Defunct satellites and spent rocket stages linger in low Earth orbit long after their missions end, threatening every operational spacecraft.
Collisions breed collisions
Each impact multiplies the debris field — the Kessler cascade — driving mission risk and insurance premiums steadily upward.
Compliance is now mandatory, and expensive
Operators face a strict five-year post-mission disposal window, yet propulsion-based disposal devours mass that should be earning revenue.
Example of debris orbiting Earth that increases collision risk.
An inflatable drag sail that lets physics do the work.
Passive by design
At end of mission the sail deploys, multiplying the satellite's cross-section. Residual atmospheric drag does the rest — pulling it down to safe disintegration on re-entry.
Ultra-light, bolt-on module
Integrates on any LEO satellite. No propellant, no thrusters, no operations after activation — and a near-zero mass penalty.
Reliable and astronomy-friendly
Rigidized beams keep the sail stable after deployment, while a low-emissivity membrane keeps skies dark and radar-quiet for ground-based astronomy.
Fire and forget. Once activated, de-orbiting is automatic — no ground segment, no fuel budget, no ongoing cost.
One product, two routes to revenue.
The same flight-qualified module serves both markets — new satellites before launch, and the thousands of defunct ones already in orbit.
Direct integration
Hardware sold directly to OEMs and constellation builders — installed before launch as the standard end-of-life kit on every satellite.

The lowest-cost seat in a market that must buy.
Existing de-orbit options span a wide range of TRLs, cost and business models — none matches a passive sail on mass and price.
