Book Description
During 1988, the National Research Council's Space Science Board reorganized itself to more effectively address NASA's advisory needs. The Board's scope was broadened: it was renamed the Space Studies Board and, among other new initiatives, the Committee on Human Exploration was created. The new committee was intended to focus on the scientific aspects of human exploration programs, rather than engineering issues. Their research led to three reports: Scientific Prerequisites for the Human Exploration of Space published in 1993, Scientific Opportunities in the Human Exploration of Space published in 1994, and Science Management in the Human Exploration of Space published in 1997. These three reports are collected and reprinted in this volume in their entirety as originally published.

Book Description
The goal of this work is ultimately to assist in the achievement of space science and exploration missions and thus to assist in the implementation of the National Space Policy. This analysis commenced with a self initiated inquiry concerning the importance of and the need for more advanced forms of space mission energy conversion, thereby permitting the accomplishment of more ambitious space science objectives. As one set of questions led to another during the initial phase of the inquiry, a drive developed to conduct an independent investigative analysis on where the space program is headed with regard to energy conversion. It ultimately has culminated in this report, the scope of which increased substantially in response to interest shown and questions raised as the study progressed. It is intended to be a presentation of all key issues which need to be addressed as part of a comprehensive space strategy. These include mission objectives, the energy options available, the preferred approach-and why, the system requirements, status of the fusion program and probability of achieving results, confinement preferences, safety, reliability, maintainability, economics, operations, program options, and recommended strategy. Various levels of depth are selected with greater emphasis placed upon the more important topics for the purpose of this report. Emphasis is placed upon confinement options and more depth upon the preferred approach. Part of the depth also reflects the technology status in some situations.

Book Description
Future space missions were hypothesized and analyzed and the energy source for their accomplishment investigated. The mission included manned Mars, scientific outposts to and robotic sample return missions from the outer planets and asteroids, as well as fly-by and rendezvous mission with the Oort Cloud and the nearest star, Alpha Centauri. Space system parametric requirements and operational features were established. The energy means for accomplishing the High Energy Space Mission were investigated. Potential energy options which could provide the propulsion and electric power system and operational requirements were reviewed and evaluated. Fusion energy was considered to be the preferred option and was analyzed in depth. Candidate fusion fuels were evaluated based upon the energy output and neutron flux. Reactors exhibiting a highly efficient use of magnetic fields for space use while at the same time offering efficient coupling to an exhaust propellant or to a direct energy convertor for efficient electrical production were examined. Near term approaches were identified. Schulze, Norman R. Unspecified Center NASA-TM-4298, NAS 1.15:4298 ...
