Liquid hydrogen is the fuel for two important U.S. rocket engines-Pratt & Whitney's RL-10 and Rocketdyne's J2. The RL-10 powers the second stage of Saturn 1, scheduled for early Apollo flights; two RL-10s combine to form the Centaur stage of the Atlas-Centaur system built to soft-land Surveyor spacecraft on the moon. J-2 forms the second and third stages of the Saturn V designed for Apollo's man-carrying lunar missions. In the near future, violent but versatile liquid hydrogen may become still more familiar as a fuel for supersonic...
...Orbital Laboratory. Future solid boosters, claims United Technology Center, developer of the booster stage, could produce lift-off thrusts of 18 million Ibs. Proponents of solids are even hoping that the Titan IIIC success will get NASA to change its mind and incorporate strap-on solid boosters in its Saturn V, the rocket that is being designed to propel man to the moon...
...brighten. Reason: aluminum demand is catching up with supply, and ingot prices have finally stabilized (at 24½? a lb.), even though the industry has two more producers and 35% more capacity than when its price troubles began. Aluminum is already a big item in everything from saucepans to Saturn rocket skins, but to advance Alcoa's recovery further Harper is pushing hard to get more aluminum into mass products-tops for baby-food jars, pop-top cans, frozen food packages, auto-engine blocks and radiator grilles. With help from his researchers, he even hopes to challenge steel...
...planning of manned space missions, the training of astronauts, and-beginning with the second Gemini shot scheduled for this fall-ground control of manned missions. But the place the missions will blast off from will still be the sandy flatland around Cape Kennedy. And until NASA's Saturn rocket is operational, the Air Force will continue to provide adaptations of its defense-developed missiles to do the blasting...
...eight interconnected engines of the big bird's booster 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...
