MOCA Student Lead: Manan Patel Student Team Members: Keven Duong, Ben Grieger, Cordelia Kohuth, Daniel Mount, Ela Ozatay, Manan Patel, Abigail Storey Faculty: Dr. Kaela Martin and Dr. Dawn Armfield Manufacturing Of Cold-Welded Assemblies (MOCA) will join aluminum members using a cold-welding process with the goal of proving a new manufacturing technique for use in space. The welding process will be carried out inside a vacuum chamber and includes alignment of the metal members, removal the oxide layer from the metal surface, and pressing the two members together until they bond at the molecular level. MOCA is designed to integrate with Arkisys’ Bosuns Locker Max as part of the C3 COSMIC Capstone Challenge track 1 for in space manufacturing and assembly. The benefit of cold welding is the low energy requirement compared to fusion welding, the lack of added heat, and no need for additional materials. Once proven, MOCA’s joining process can be used to build structures in space whose size and shape are constrained only by the continued supply of raw material.
MOSS Student Lead: Bruce Noble Student Team Members: Paytn Barnette, Paul Brich, Connor Hall, Brendan King, Bruce Noble, Parker Scribner, Lawrence Tolentino Faculty: Dr. Siwei Fan and Dr. Matthew Haslam The Mission for Orbital Service and Support (MOSS) is designing an on-orbit propellant transfer mechanism for satellites in Geostationary Earth Orbit (GEO). Satellites require propellant to perform orbital corrections, orientation, and eventually disposal. When satellites in GEO run low on propellant, satellites must use the last of their propellant to be disposed of and deactivated in a special graveyard orbit. MOSS is working to extend the life of satellites in GEO by transferring propellant to the satellites, allowing them to continue making orbital corrections. MOSS will restore life to these satellites by flowing propellant backwards through the satellite’s engines.
