Abstract

A gossamer structure for end-of-life disposal of spacecraft to mitigate space debris is considered in comparison with other end-of-life disposal concepts to determine when it would be preferable. A needs analysis, potential use cases, and concept of operations are developed. A survey of disposal strategies is presented for comparison before a downselection of viable competing techniques: solar sailing, high- and low-thrust propulsion, and electrodynamic tethers. A parametric comparison of the downselection competing techniques is presented. Exploiting solar radiation pressure on the structure is of limited value. Atmospheric drag augmentation was found to be of most benefit for end-of-life disposal when an entirely passive means is required, allowing the gossamer device to act as a “fail-safe”. This is applicable to only low- and medium-mass spacecraft or spacecraft that are unlikely to survive atmospheric reentry, hence minimizing risk to human life. It does not significantly alter the operating ceiling altitude but does alter the maximum allowable end-of-life mass. Peak mass benefit occurs in the altitude range 550–650 km and is largely independent of deorbit time.
