...electronic mechanisms that will control the bird. Capsule specialists poise their instrument-packed pod atop the rocket to check it out. If all goes well, fuel specialists attach the plumbing that will fill the projectile's maw with explosive cargoes of liquid oxygen and kerosene, or intractable liquid hydrogen...
...toss a dummy Surveyor (soft-landing vehicle) to the moon's orbit, climbed only a few feet before a valve misfunctioned and the rocket fell back on its pad. Thin-walled fuel tanks ruptured, and more than 100 tons of liquid oxygen and kerosene burst into flames. The hydrogen-burning second stage added tons of liquid hydrogen to the holocaust. The 120-man launching crew dared not emerge from their dugout for 21 hours...
Other fuel cells already in operation combine pure hydrogen and oxygen to form water. In the process the hydrogen gives up electrons that flow out of the cell as electric current. But hydrogen is a touchy, expensive fuel, and since it is a very light gas, only small amounts can be stored in large, un wieldy pressure tanks. The Esso cell burns familiar methanol (wood alcohol) and gets its oxygen free, out of ordinary...
...stage are training vehicles on which U.S. engineers are learning to handle the five much larger engines that will boost the Apollo spaceship on its voyage to the moon. Saturn's second stage teaches an even more difficult art. Its six Pratt & Whitney RL-10 engines burn liquid hydrogen, which is incredibly touchy to handle, but has an added efficiency that is considered essential for the moon project. The smooth success of last week's launch suggests that LH2 has at last become a routine fuel...
Purcell was one of the first scientists to tune in on radio waves emitted by hydrogen clouds in outer space. The Gerhad Gale University Professor, he won the 1952 Nobel in physics...
