Paper Abstract

On-orbit servicing can provide significant benefits for scientific space programs through maintenance and upgrades of scientific spacecraft. The Hubble Space Telescope (HST) captured these benefits throughout its life because it was designed to be serviceable. However, serviceability has often been excluded from other telescope programs since the cost of serviceability could not be quantitatively justified. This paper develops a framework to determine the value of including serviceability in a space telescope. The framework incorporates three main principles: separation of cost and benefits, calculation of value through comparison of servicing to replacement, and the use of Monte-Carlo simulation and decision rule analysis to account for programmatic uncertainty and management flexibility. To demonstrate how the framework can be used in practice, a case study was performed with representative data from HST.
