Moon & Mars Orbiting Spinning Tether Transport - Tethers Unlimited

Tether Facility Reboost• Use Electrodynamic Propulsion NearPerigee to Reboost Orbit– Collect electrons from ionosphere atone end of tether & emit electrons atother end of tether– Use power from batteries to push curentalong tether– Current interacts with geomagnetic fieldto give JxB force– Vary current to generate net thrust• To achieve Reboost in 30 days:– Solar Panel Power: 100 kW– Power To ED Tether: 300 kW– Currents: ~15 A• Issues:– High Power, High Voltage (20 kV)TUI/MMOSTT 22
