Space debris consist a major challenge for future projects on the space elevator as on
regular space flight itself. The mechanics of large spaces (MLS) is here used to anticipate the
dynamics of membrane tethers, proposed as a genuine solution to be deployed in orbit for recovery
of these dangerous space debris. Made of super-strong, light materials like M5 or carbon nano-tube
ribbons, they are proposed to be extended at LEO altitudes with a span of up to 100 meters.
Numerical modeling show that membrane structures manifest usual libration motion around local
vertical and offer proper condition for collecting small orbital debris over long periods. The
dynamics of these tether systems, especially during collisions, is modeled by computer codes and
presented through graphical diagrams.
