Title:  Architecture Study for a Fuel Depot Supplied from Lunar Resources

Abstract:  Heretofore, most treatments of space depots assumed the depots would be supplied and serviced from the Earth. However, the confirmation of large deposits of water ice at the lunar poles in 2009 suggests the possibility of supporting depots with propellants produced from the harvesting of lunar ice deposits.

This thesis effort seeks to identify an optimum architecture for a space depot supported from lunar resources. Three factors – the location of the depot, the location of the fuel processing (electrolysis/liquefaction), and the type of fuel container – are combined to identify 12 potential architectures.  Two design reference missions – a commercial mission to service satellites in geostationary orbit, and a Government cargo mission to Mars – are developed and used to create demand on the proposed architectures. Linear programming techniques are then employed to evaluate which architecture best delivers liquid hydrogen and liquid oxygen to the customer. The combined delta-v (supplier and customer) for each architecture is also calculated.

Bio: Tom Perrin has a BS in Mechanical Engineering from the United States Military Academy, and an MS in Systems Engineering from the University of Alabama in Huntsville. He works as a contractor for NASA/Marshall Space Flight Center in Huntsville, Alabama. He has a 25 year history working in military and civil space. His military work includes architecture development for the Army use of space to support tactical operations, and a preliminary design for a tactical reconnaissance satellite. His NASA work includes payload operations for the space shuttle, business development for small and large NASA contractors, and systems engineering for the Hinode Solar Observatory and the Ares I rocket. Tom is currently assigned as a senior ground operations systems engineer supporting the development of the Space Launch System (SLS).
