Assembling the basic structure
Specific tasks to be undertaken by the NASA-Johnson, Phase B management of the manned Space Station are described. These tasks include the analysis, definition, and design of the following systems: assembly trusses and structures; interconnection modules; airlock system; heat rejection and transport; guidance, navigation and control systems; mechanical systems; resource integration; data management; communication and tracking; habitat for the crew; hardware need for cost-effective EVA; interface and berthing for compatible space-transportation system; and software development environment. The components, functions, and the key design goals of each of these systems are discussed.
