Abstract:
A transportation node that orbits a celestial body includes a truss having two ends with least at one end of the truss having at least one coupling tether cable with a tether tip at individual ends. The truss, while orbiting the celestial body, rotates around its center of mass in a direction to control the tether tip in relation to a surface of the celestial body and to cancel a relative velocity between the tether tip and the surface for transferring a payload attached to the tether tip to and from the surface. A method of transferring payload to and from a celestial body includes reeling in/out from an orbiting transportation node a coupling tether cable with a tether tip configured to attach to the payload.
