Summary

Extended cryogenic propellant storage periods have become increasingly important within NASA. Furthermore, cryocooler and passive insulation technology advances have substantially improved the prospects for zero boiloff (ZBO) storage of cryogenics. Accordingly, a cooperative effort by NASA's Ames Research Center, Glenn Research Center, and Marshall Space Flight Center has been implemented to develop ZBO concepts for in-space storage of cryogenic propellants. Accomplishments include analytical modeling; an early subscale liquid hydrogen (LH2) demonstration; a flight-like 10 W, 95 K pulse tube cryocooler; and assembly of a large-scale test article for an LH2 system-level demonstration. Future testing with flight-like cryocoolers is planned.
