EVA Concept of Operations for International Space Station Maintenance 2000-01-2440

An overview of the proposed operational methods for performing Extravehicular Activity (EVA) maintenance for the International Space Station (ISS) is provided. External maintenance of ISS will be required during assembly and will continue for at least ten years after assembly is complete. It is likely that the operational methodology for performing maintenance will evolve as more on-orbit ISS EVA experience is gained. However, an initial operational plan is necessary for timeline and tool development. Initial operational concepts outlining assumptions regarding how EVA operations will be conducted during maintenance of ISS after assembly complete are provided. These maintenance scenarios are designed to reduce overhead wherever possible in order to make the EVA operations more efficient. Also presented is a summation of orbital replacement unit (ORU) information as it pertains to the operational concept.
