Propellantless Propulsion System

Jan-21-18 An innovative propellantless propulsion system could collect space debris and extend the orbit of the space station.

The propulsion system is based on the Lorentz drag principle, and would rely on a conducting tether extended from the satellite during orbit. The tether would passively generate power as the satellite’s orbit lowers into the Earth's magnetic field, or could use available onboard power to create a thrust to increase the craft’s orbit.

Although the technology is not new, previous tether examples were too expensive, complex or contamination-prone. In contrast, the new tether design is made up of a narrow aluminum tape coated with a “low work” material that demonstrates improved electron emission during exposure to sun or heat.
