This paper presents the currently envisioned role of the Space Station relative to servicing both at and distant from the Station. Once operational (1990+), the Station will substantially benefit from the experience gained via the Orbiter’s servicing role, i.e., during the next 5 to 6 years. It is anticipated that there will be a complimentary role for both the Orbiter and the Station for varying servicing functions. Focus of this paper will be on the Station servicing activities and on orbital mechanics, which play a pivotal cornerstone in the accomplishment of the servicing mission. Both the Teleoperator Retrieval System and Orbital Maneuvering System are key elements to servicing functions, e.g., spacecraft retrieval, capture, and/or on-site servicing. Servicing technology is available today and spacecraft are already being designed for that purpose. Accordingly, an extension of the Orbiter’s servicing capability to the Station will be a natural and evolutionary process well within the present state-of-the-art.
