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.
