In-Space Storable Fluid Transfer for Prepared Spacecraft
This document defines best practices and requirements for the design, verification, and operation of prepared in-space storable fluid transfer systems and interfaces. The term “prepared” describes a spacecraft, spacecraft interfaces, and other accommodations intentionally designed to enable safe and efficient servicing. Modification of an existing spacecraft storable fluid transfer interface is outside the scope of this document. However, any spacecraft modified to meet the criteria stated herein may be considered “prepared.” The term “in-space” describes an environment outside a planetary atmosphere. This document includes requirements and recommendations for both servicer and client spacecraft. At present the recommendations’ scope is limited to storable (non-cryogenic) propellants and associated pressurants.
