A Satellite-Service Approach for Long-Duration Space Platforms 820851

The Space Platform, a new space facility to be carried into orbit, maintained, and logistically supported using the Space Shuttle, would provide electrical power, active thermal control, communications, data management, and orbital attitude control for attached payloads. It also could be expanded in capability to support habitat modules for permanent manned space operations. The Space Platform design includes provisions for on-orbit service and maintenance to extend its operational life through resupply of consumables and changeout of failed items or limited-life components. This paper presents concepts for service and maintenance of Space Platform and reviews specific design considerations for serviceability. The satellite-service approach presented takes advantage of astronaut work and decision-making capabilities in both intravehicular and extravehicular (EVA) modes. Projected Space Platform EVA, together with required support equipment including service tools and work aids is described; specific techniques, procedures, timeline estimates, safety considerations, and training requirements are discussed.
