...years, scientists have been tantalized by the prospect that water ice lurks in craters near the poles of the moon, places where the sun never shines and temperatures perpetually hover hundreds of degrees below zero. A decade ago, the Lunar Prospector orbiter caught a whiff of hydrogen, which may or may not have been evidence of that...
...moon holds prospects for the future. If humans are ever going to establish a long-term presence on the moon, they will need water to drink, and tapping a local supply would be a lot more convenient than lugging it from Earth. Beyond that, water can be split into hydrogen and oxygen - the former makes pretty good rocket fuel, and the latter is useful for breathing...
...explosive in makeshift laboratories. For terrorist groups, however, the risks of TATP are outweighed by the advantages. The white, sugarlike powder is lightweight and nearly odorless (the better to evade bomb-sniffing dogs) and contains no nitrogen (foiling scanners that detect nitrogenous bombs). Its basic ingredients - acetone, hydrogen peroxide and acid - are readily available in beauty supplies and home-improvement products. Al-Qaeda operatives have been using the stuff for years...
...beauty-supply stores in the Denver area using stolen credit cards. At the Beauty Supply Warehouse on East Sixth Avenue, a cornucopia of hair extensions, gels and wigs arrayed in a former skating rink, investigators found Zazi's image on security tapes. He was pushing a cart full of hydrogen peroxide-based products down the aisle...
...research, which used the intensity of the colors that bounce off the surface of the moon when it's hit by sunlight, proves that there are traces of both water and a closely related molecule called hydroxyl. Scientists now believe water could be produced in the lunar soil when hydrogen from solar winds combines with oxygen-rich substances on the lunar surface. Another theory centers on water-laden comets and meteorites hitting the moon...
