Critical Environmental Interactions Documentation and Their Application to Future Air Force Mission Concepts

N. J. Stevens / M. E. Kirkpatrick / C. S. Underwood / R. P. Stillwell

This report covers the second phase of the Spacecraft Environmental Interaction Investigation. The objective of this phase of the contract was to identify and rank interaction technical issues affecting military space system development. The goal of this phase was to identify potential detrimental interactions, to review existing military standards for adequacy in aiding designers, and to recommend standard and handbook development. These objectives and goals were met by considering environmental interactions with five specific large space system designs: Space Station in Polar Orbit, Geostationary Space Platform, Nuclear Powered Satellite, Orbital Transfer Vehicle, and Astronaut Life Support/Maneuvering Systems. The designs were reviewed from an engineering point of view using the environmental interaction technology data obtained from the first phase of this contract. From this review, the interactions were synthesized into a comprehensive list. Available Military Standards and Handbooks for each interaction were surveyed and recommendations were made for the development of needed documents.
