It is as if the cable were two spokes of a giant wheel that rolled along the ground (Figure 2). It involves a much smaller cable in low orbit which rolls in its orbital plane and whose ends brush the Earth with the rotational motion cancelling the orbital motion at ground level. The second kind is newer, but has also been the subject of rediscovery (2) (5). It has been rediscovered on at least three separate occasions (1) (4) (6) and is the central theme of two science fiction novels (3) (7). Anchored to the ground and kept taut by a ballast at the far end, this structure could be used as the backbone for an orbital elevator system (Figure 1). The simplest, but also largest, has a filament dropped to the surface from synchronous orbit, counterbalanced by one extending outwards. Two major types of Earth orbital cable (sometimes called skyhook) have been investigated in the literature. Although the concept promises to be one of the simplest and cheapest for massive orbital commuting in the long run - and could be used today for travel in space and on the Moon if there were call for it - present strength of materials limitations make the simplest variants of the idea infeasible for the most immediate need, namely transportation to and from Earth. Dream OnĪ relatively new class of proposals for travel to and through space involves the idea of very long, very strong, tapered cables, spinning so that their tips move at or near orbital velocity. Judicious use of a large satellite incorporating a high specific impulse engine and a long tapered Kevlar cable, itself transported to orbit in multiple shuttle flights, could cut the total number of launches, including the satellite construction phase, to about 300. The task of delivering 50 million kilograms of payload to low Earth orbit would require almost 1700 launches of the Space Shuttle if done in a straightforward manner.
