摘要

Space tethers represent a new technology to increase the capabilities and versatility of Earth-orbiting spacecraft. However, tethers also present a new type of collision hazard for spacecraft. In addition, space tethers themselves are especially susceptible to severing by orbital debris collisions. Traditional mathematical models that are used to compute collision rates between orbiting objects are based on the assumption that the spacecraft themselves are much smaller in size than the scale of their orbits (i.e., the spacecraft are treated as mathematical points). This assumption begins to break down for tethers, which can be many kilometers in length. In this paper, a mathematical procedure is introduced that allows for collision rate calculations for extended structures such as tethers. These equations are then applied to several current and planned tether missions to determine their mean sever lifetime and their risk of collision with other orbiting bodies.
