It shows how space tethers have already been used to stabilize spacecraft using tidal forces and to generate artificial gravity using a spinning system with a spacecraft connected to a counterweight via a cable. Tethers can also generate electricity by dragging spacecraft through the Earths magnetosphere, as was attempted with partial success during two Space Shuttle missions. Using electrodynamic forces, conductive tethers can also accelerate or brake a spacecraft.Probably the most exciting tether concept is the space elevator, consisting of an incredibly strong long cable that stretches from the Earths surface into space. Solar powered climber machines, which are already under development, could use such a cable to haul cargo into orbit. The author also describes how space tethers can change the orbit of satellites, by effectively moving their center of gravity through the deployment of long cables. Tethers rotating at high speed can be used to accelerate or slow down spacecraft that briefly latch to them. In principle, such momentum exchange tethers can be used to fly a space probe from low Earth orbit all the way into orbit around Mars, without the need for rocket propulsion. A tether can also provide scientific information on the magnetosphere of the planet its orbiting.Michel van Pelt explains the principle of space tethers: what they are and how they can be used in space. He introduces non-technical space enthusiasts to the various possibilities of space tethers, the technological challenges, the potential benefits and their feasibility. He illustrates how, because of their inherent simplicity, space tethers have the potential to make space travel much cheaper, while ongoing advances in tether material technology may make even seemingly far-fetched ideas a reality in the not too distant future.
