Regenerative ECLSS and Logistics Analysis for Sustained Lunar Surface Missions

Sustained Lunar Campaign: Annual crew missions to the lunar surface with 2 to 4 crewmembers living in a Surface Habitat (SH) and/or a Pressurized Rover (PR) for 30 days or longer.

Missions will require annual resupply of logistics to the lunar surface: Logistics include consumables, EVA consumables and spares, carriers, surface system spares and maintenance, and science and utilization.

Water and gas (may) dominate the total logistics resupply: Water and gas = a direct function of the level of closure provided by the ECLSS in the Surface Habitat (SH) and the Pressurized Rover (PR).

Logistics requirements will drive the number of required resupply landers, launch vehicles, and resupply costs.

Goal of Paper: Determine a recommended regenerative ECLSS architecture option to minimize the tradeoff between ECLSS Delivery Mass and Logistics Resupply Mass
