Earliest lunar orbit rendezvous schemes involved use of one or more extremely lightweight, unpressurized lunar landers to take a single astronaut to the lunar service. This Langley design used cryogenic propellants. An even more marginal cryogenic design was estimated to gross 1,460 kg - to be compared with the 15,000 kg / 2 man design that eventually was selected. Propellant load estimated.
Craft.Crew Size: 1. Design Life: 1 days. Total Length: 2.6 m. Maximum Diameter: 3.5 m. Total Mass: 3,284 kg. Total Payload: 150 kg. Total Propellants: 2,200 kg. Main Engine Propellants: Lox/LH2. Main Engine Isp: 444 sec.
