The progress of the Robotic Resupply Mission III (RRM III) Cryogen Demonstration System (CDS), an on-orbit experiment to store, transfer and solidify a cryogen, is described. This experiment would demonstrate techniques for resupplying science missions that use liquid or solid cryogens. RRM III has progressed through System Requirements Review, and is moving towards Preliminary Design Review. This paper describes the driving requirements, operations, and an overview of the design status of the RRM-III CDS. Since 2012, the cryogen has been changed from liquid argon to liquid methane, an additional robotic transfer operation has been added, and progress has been made on the design and selection of key components for transfer operations. This paper also provides an overview of critical subcomponents of the cryogen demonstration system.
