The International Space Station complex - Promise and problems

The current planning status of the International Space Station is reviewed from a NASA perspective, with a focus on aspects affecting the contributions of the international partners ESA, Japan, and Canada. The modifications implied by the shift from the previous double-keel configuration to the current phased-deployment (Block 1 - Block 2) approach are considered in detail and illustrated with drawings and a table listing the baseline assembly sequence. It is pointed out that the originally proposed non-NASA components can all be accommodated in the new configuration. The need for intermodule commonality of equipment form, fit, and function is discussed, and it is recommended that independent user boards be set up to select and coordinate experiments, and that the user boards of the partners open channels of cooperation and mutual support.

Space Station utilization

This paper focuses on the emphasis NASA has placed on Space Station utilization and the approach used to develop informed user communities in science, technology, and space commercialization. A major program objective continues to be the identification of potential Space Station users, assimilation of user requirements, and the use of those requirements both to drive the Station's design and to guide the Station's evolution. NASA's goal is the creation of a user friendly, multipurpose, multidiscipline research facility that will evolve on-orbit and maintain the position of a premiere space laboratory during its projected 30-year useful life.

Facilities and programs for research in a low-gravity environment

The history of NASA-supported microgravity material-processing research on Apollo, Skylab, and Apollo-Soyuz is reviewed; the currently available ground and Space Shuttle laboratory facilities are characterized and illustrated with drawings; and an overview of the Microgravity Science and Applications Program (MSAP) is given. The ground systems include drop tubes, drop towers, aircraft, and levitators; on the Space Shuttle, facilities are provided in the Orbiter middeck, in the payload bay, and in the Spacelab module. The aims of MSAP and the mechanisms for academic or industry participation are outlined, and typical results of MSAP-organized research in electronic materials, biotechnology, metals and alloys, glasses and ceramics, combustion, fluid dynamics, and transport phenomena are summarized.
