Artist's concept of possible exploration programs. A crew of four descends to the lunar surface in a spacecraft designed to utilize oxygen produced on the Moon for propellant. Because of the high performance advantages of in situ propellants, the spacecraft does not need to rendezvous with a second spacecraft in lunar orbit.
