A Cost Analysis For A Nuclear Space Tug

Lynette F. Ortiz*

Abstract

This paper is an investigation of the cost effectiveness of using a nuclear thermal propulsion engine (NTPE) to transfer payload from a low Earth orbit (LEO) to a geosynchronous Earth orbit (GEO). Costs are calculated for single and multiple uses of NTPEs and are compared with using a chemical rocket engine to perform the same task. The reusability and high performance of the NTPE has the potential for significant cost reductions.
