On-orbit assembly operations and in-space infrastructure

Abstract

The paper describes the development of a set of top-level system requirements for an in-space infrastructure which will accommodate the vehicles proposed for the Space Exploration Initiative (SEI). Issues considered include the current SEI mission strategy, the launch capability, the role of Space Station Freedom (SSF), the on-orbit assembly operations, and the manned tended versus robotic capability. Current SEI mission strategy coupled with SSF planning led to the conclusion that an independent assembly servicing facility (ASF) will best meet the requirements of the SEI program, and an analysis was performed to define the functions required at an ASF. It is shown that the ASF functions can be performed by telerobotic operations.
