Space Tether Systems

Momentum-exchange cables that fling payloads without expending fuel.
Space Tether Systems

Rotating tethers in orbit catch and release spacecraft, transferring momentum to change their trajectories. This enables propellant-free boosts from LEO to higher orbits or interplanetary trajectories. Electrodynamic tethers can also generate power or provide drag for orbital maneuvering.
