L02 Delivered to Earth-Moon L2 ETO Mass = 930 MT 4. Lunar L02 Delivered to LEO ETO Mass = 780 MT 5. L02 and LH2 Delivered to Earth-Moon L2 ... ETO Mass = 600 MT BOTTOM LINES: Lunar-produced propellants may (on the margin) reduce the costs of manned Mars missions. Earth-Moon L2 appears to be best staging point. L02 = Liquid Oxygen, LH2 = Liquid Hydrogen, LLO = Low Lunar Orbit L2 = Libration Point 2, MT = Metric Tons
