ESA Developing Solar Sail to Safely Deorbit Satellites | Parabolic Arc | Wake up Rosetta | Scoop.it

PARIS (ESA PR) — When satellites reach the end of their working lives, they may pose a threat to other spacecraft as they continue to orbit in a dormant state for many decades. But now a new way to deorbit ageing satellites in a safe manner is nearing its first test in space.

 

In the future, satellites might carry a packaged ultra-lightweight ‘gossamer sail’ to open as they head towards retirement. The increased aerodynamic drag would pull the craft out of orbit to burn up in the high atmosphere, reducing the risk of catastrophic collisions and creating a sustainable space environment for future generations.
