Glasgow University has developed a system that would allow small satellites to slowdown. In partnership with nanosatellite manufacturer Clyde Space, the “aerobrake” is a foldable system that can be added to the structure of cube satellites before they go into LEO.

The objective of the “Aerodynamic End of Life Deorbit System” (AEOLDOS) or aerobreak is to generate aerodynamic drag against the thin upper atmosphere to accelerate its re-entry descent, during which the satellite burns up. The system offers a way to successfully deorbit a satellite and help reduce the amount of orbital debris.

The aerobreak is a lightweight mechanism made from a thin membrane supported by tape-measure-like bars. It can additionally help extend the scope of nanosatellites by allowing operators to place the spacecraft at higher altitudes knowing they will be able to produce the drag needed to dispose of it in time.
