S93-45592 (1993) --- (Artist's concept of possible exploration programs.) The lunar crew refills the propellant tanks on their spacecraft with oxygen produced on the Moon. This allows them to return directly to Earth, reentering the atmosphere in the conical crew module, and touching down at a prepared landing site. This image was produced for NASA by John Frassanito and Associates. Technical concepts from NASA's Planetary Projects Office (PPO), Johnson Space Center (JSC).
