Abstract
This study evaluated the relative benefits of proposed deep space propulsio n technology improvements in three areas: advanced chemical, solar electric , and solar sail. Within each area, specific states, representing current t echnology (present-1999), mid-term (2000-2004), and far term (2005+), were selected for evaluation. The figures of merit used were net spacecraft mass delivered, size of the launch vehicle needed, trip time, cost, and risk. B ased on the results, an investment strategy was recommended to NASA headqua rters, along with possible scenarios for its implementation. (C) 1999 Publi shed by Elsevier Science Ltd.
