Description
Summary:A space-based laser ablation propulsion system has the potential to produce a paradigm shift in the management of space resources. This paper outlines practical considerations for in-space use of a laser ablation propulsion system for generating an attractive force between two space objects. Limitations of energy delivery to the target are determined, and mass removal and impulse generation are calculated as functions of range for a variety of laser wavelengths. A unique in-space application is proposed for a reversed-thrust system: emergency retrieval of astronauts and tools on-orbit. [PUBLISHER ABSTRACT]
