...module. If all is well, they will have a brief snack, sleep for four hours and eat a leisurely dinner. Only then will they struggle into their bulky space suits, visored helmets, boots and gloves. With their Portable Life Support System (PLSS) backpacks, which supply air conditioning and enough oxygen for four hours, each will be encased in 183 lbs. of equipment. But under weak lunar gravity (one-sixth the earth's), the total weight of each fully burdened astronaut will be only about...
...squeal could be used. Water vapor steaming out of the heated rocks could drive power turbines before being condensed into drinking water. When lunar water is finally available in ample supply, it could even be used for rocket fuel. Moon technicians will decompose it into hydrogen and oxygen gases by electrolysis, then feed the gases into a lunar cryostat, a device that can reach extremely low temperatures during the chill lunar night without using power. The resulting products would be liquid hydrogen and liquid oxygen, familiar space-age fuels...
...calcium carbonate. The carbon dioxide would be released into the atmosphere of a covered garden to sustain green algae living in a tank of water. The rapidly reproducing algae would not only be an excellent source of protein for humans on the moon but would also produce vitally needed oxygen as a byproduct of photosynthesis...
...Lake Erie to a safe if silent emergency landing in a field in Canada; the pilot had neglected to check the fuel before taking off. Denver's Aspen Airways navigates around 14,000-ft. mountain peaks while flying at 13,500 ft. without benefit of cabin pressure or oxygen (except on request). Quite understandably, the line bills itself as "the world's fastest ski lift...
...billion in plankton, says Biologist Charles F. Wurster Jr., chief scientific adviser to a New York conservationist group called the Environmental Defense Fund, can substantially hinder the photosynthesis process. On a larger scale, such interference could have a devastating effect, since phytoplankton produces 70% of the earth's oxygen...
