Develop architecture for mining Mars water from a notional reserve and processing that water into propellant ready to use for future systems on the Martian surface. The concept must encompass all stages of ISRU: getting to a notional subsurface ice reserve, acquiring the ice, using it to produce fuel and oxidizer, and liquefying and maintaining those propellants long-term on the surface. Masses, powers, volumes, and costs of the systems must be identified.
