ECLS resupply for Space Station FreedomThe design of logistics carriers is presented emphasizing the use of cost-effective pressurized and nonpressurized versions to resupply consumable fluids and provide on-orbit support for the Space Station Freedom. The requirements for the Environmental Control and Life Support (ECLS) system include high-pressure oxygen and nitrogen as well as consumables that do not require pressurization. The nominal and contingency requirements are given for logistics carriers designed to support various mission scenarios by resupplying and servicing fluid systems on-orbit. The resulting design overview for the logistics carriers describes the cryogenic-nitrogen storage during launch and operation of the unpressurized version and the flexible payload-support capacity of the pressurized version. The carriers are characterized as lightweight and versatile, and the resupply of cryogenic nitrogen is a flight-proven capability.
