Commercial cargo transport service for ISS

This paper examines ISS cargo traffic requirements, provides an assessment of current and proposed cargo vehicles envisioned for ISS cargo transport, and examines major cost drivers associated with development of cargo transport systems. Consideration of these factors, coupled with SPACEHAB's extensive involvement in cargo transport to the Mir and ISS, has led to the development of a Commercial Payload Service (CPS). The CPS mission models, system description and performance, and structure of the commercial service model are presented.
