Russian Planets? The U.S. moon program has been delayed for more than a year by the Apollo launching-pad fire. But despite the holocaust, and the flawed performance of the Saturn 5 moon rocket three weeks ago, it is still ahead of the Soviet Union's. Engineers now blame the Saturn 5 failures on what appear to be a pair of rare flukes-a leak in a secondary fuel line and crossed cut-off signal wires that shut down the wrong rocket engine. The Russians have no moon rocket to compare with the Saturn 5, which is capable...
...Saturn 5 lifted off its Cape Kennedy launching pad with dramatic precision last week, ground controllers had visions of a repeat of last November's near-perfect maiden flight of the giant rocket. Their optimism was premature. Only six minutes after lift off, Saturn encountered the first of a series of troubles that may cause a delay of months in landing the first astronauts on the moon...
After igniting successfully, two of the five second-stage J-2 engines inexplicably shut down nearly 2½ minutes early, reducing thrust by 400,000 lbs Although Saturn's sophisticated guidance-and- control system automatically ordered the remaining three engines to fire longer, the rocket had not achieved its programmed velocity by the time the third stage was ready to take over. Thus to achieve orbital velocity of 17,500 m.p.h., the third stage was required to fire 23 seconds longer than planned, consuming 20,000 extra pounds of fuel...
...week's end, disappointed space scientists were picking through telemetry attempting to discover what had gone wrong with the previously reliable Saturn. Preliminary analysis suggested that the two second-stage rocket engines might have been damaged during the separation of the first stage and that an electrical malfunction had prevented the third stage from restarting in orbit The misfires dimmed NASA's hope that the next Saturn shot would carry three astronauts into orbit. Instead, if further diagnosis shows that the rocket's ills are serious, it may be necessary to prove them cured in another unmanned...
...cans. With most beer and soft-drink cans now sporting aluminum pop-tops, Alcoa and the rest of the industry have begun pushing sales of cans made entirely of aluminum. Another promising market is aerospace. Alcoa provided most of the 1,000,000 Ibs. of aluminum used in the Saturn V moon rocket, is also supplying 105-ft-long heat-treated aluminum plate for the wings of Boeing's new 747 jumbo jetliners...
