Making Propellants on Planetary Surfaces Saves on Launches and Cost (Gear Ratio Effect) Every 1 kg of propellant made on the Moon or Mars saves 7.5 to 11.2 kg in LEO ▪ Enable exploration by staging required resources in forward locations − Earth Orbit (LEO, GEO) − LaGrange Points (EML1 and EML2) − Lunar Orbit − Lunar Surface ▪ Resources include propellant depots, propellant production facilities (initially H2 and O2), and consumable storage Potential >283 mT launch mass saved in LEO = 3+ SLS launches per Mars Ascent ➢ Savings depend on in-space transportation approach and assumptions; previous Mars gear ratio calculations showed only a 7.5 kg saving ➢ 25,000 kg mass savings from propellant production on Mars for ascent = 187,500 to 282,500 kg launched into LEO Moon Lander: Surface to NRHO − Crew Ascent Stage (1 way): 3 to 6 mT O2 − Single Stage (both ways): 40 to 50 mT O2/H2 Earth-Moon Lagrange Point 1 (EML1) Geostationary Earth Orbit (GEO) EML2 Low Earth Orbit (LEO) Support Vehicles Personnel, Cargo, and Support Vehicles Cargo Low Lunar Orbit (LLO) 11PDF Image | NASA Applications using Fuel Cell Electrolysis Technologies
