A Review of In-Space Propellant Transfer Capabilities and Challenges for Missions Involving Propellant Resupply

This paper captures and transfers knowledge of in-space propellant transfer accomplishments and communicate the remaining challenges to a new generation of NASA engineers as multiple NASA programs and centers have worked related and applicable efforts. The Propulsion Technical Discipline Team (TDT) established a plan to draft this paper as an effort to help engineers and decision makers recognize and access the various islands of experience that have formed within the agency as different NASA directorates and projects have embraced the challenges associated with propellant transfer.
