A propellant-less device for deorbiting satellites and mitigating the space debris problem
Current in-space propulsion technologies work under the law of action-reaction. Consequently, the propellant determines the satellite payload mass and mission lifetime. The EU-funded E.T.PACK envisages a new era in which satellites could deorbit without using on-board power and fuel. The project will develop a propellant-free device based on a low work-function tether that operates under different principles. Instead of carrying propellant, it produces a drag force by taking advantage of the natural space environment, which includes the geomagnetic field, the ambient plasma and the solar radiation. The device can prevent proliferation of space debris, one of the most important challenges the aerospace industry.
