Magnetically Latching Cryogenic Fluid Coupler for Lunar Surface Operations

Abstract

Envisioning future lunar exploration and habitation necessitates addressing numerous needs related to sustaining human life and managing resources on the lunar surface. One of these needs is proficient cryogenic fluid management, which is particularly challenging in the dusty lunar environment. To address the need for a robust and environmentally tolerant cryogenic management solution, the CryoMag Coupler was developed as demonstrative solution. The CryoMag is a low-force cryogenic coupler that facilitates the mating, latching, and de-mating of cryogenic connections by way of a magnetic interface, providing a dust-tolerant solution to manage cryogenic fluids in the challenging lunar environment. This paper details the design and testing of this Coupler.
