MOSS - MISSION FOR ORBITAL SERVICE & SUPPORT Paytn Barnette - Aerospace Engineering, Paul Brich - Aerospace Engineering, Chanel Davis - Aerospace Engineering, Connor Hall - Aerospace Engineering, Brendan King - Aerospace Engineering, Bruce Noble - Aerospace Engineering, Parker Scribner - Aerospace Engineering, Lawrence Tolentino - Aerospace Engineering MENTORS Siwei Fan , Aerospace Engineering Matthew Haslam , Humanities and Communication 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 eventual disposal. When satellites in GEO run low on propellant, they 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 backward through the satellites’ engines. This system will allow for refueling without the need to cause permanent damage or install a new interface.
