The Basics,of thin strands of high-strength fibers. If electricity has to flow through them, conducting wires are also incorporated. There are many types and applications of tether systems; as we will see, the possibilities for this novel technology are amazing. In this chapter the main types of space tethers

Objects with a low perigee altitude remain in orbit for years, but ultimately get sufficiently slowed down by the tiny aerodynamic drag to fall back to Earth and burn up in the atmosphere.
