...moon?s small mass and low gravity that prevents it from keeping hold of even a tenuously thin atmosphere. But oxygen needn?t exist only in gaseous form above the ground. It can also be entrained safely in certain kinds of rocks. Gather the rubble and either treat it with chemicals or blast it with heat, and you can free up unlimited quantities of oxygen both for breathing and for rocket fuel...
...lunar mineral that may hold the most oxygen promise is ilmenite, a titanium oxide brought back from the moon?s Taurus-Littrow region by the Apollo 17 crew in 1972. To determine how heavy the ilmenite concentrations are at that site and to look for other outcroppings as well, NASA recently decided to conduct telescope surveys of four lunar regions: Taurus-Littrow, Hadley-Apennine-landing site of Apollo 15-the unexplored Aristarchus impact crater and nearby Schroter?s Valley. Though ground-based telescopes would ordinarily be suitable for this work, in this case they wouldn?t do, since the scientists...
...also in Schroter?s Valley and in especially high concentrations in Aristarchus crater. Aristarchus would make an especially good landing site for future geologists, because the impacts that create craters blasts away surface material, providing a detailed look far below ground. Combine that with the ready lode of oxygen-rich ilmenite, and you?ve got a prime spot for a future moon base...
Alarm was needed. Victims could die in 24 hours. Symptoms included bleeding from the nose, mouth, ears and eyes. Some people turned so dark blue from lack of oxygen that an Army physician noted that "it is hard to distinguish the coloured men from the white...
McCombe retired under pressure in 2003, when his health required him to carry around an oxygen tank. He suffered from diabetes and a weak lung...
