...fuel line that broke under the strain of liquid hydrogen flowing through it at approximately 100 m.p.h. The break set off a chain of events that lowered pressure in the engine, which automatically shut down. Because of an incorrectly wired circuit, the shutdown on the first engine sent a signal to another, perfectly operating engine, erroneously ordering it to shut down also...
...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 of 7,500,000 Ibs. of thrust. NASA Administrator James Webb believes they will soon test a moon booster with a 10,000,000-lb. thrust capacity...
Blue Star. Using the coordinates given by Hewish, Astronomer Frank Drake trained the giant Arecibo, Puerto Rico, radio telescope on pulsar 3 and discovered that each of its signals was composed of two closely spaced peaks. The peaks were so sharp, he said, that the signal may originate from an object as small as a few hundred miles across; if pulsar 3 were much larger, the peaks would be gradual and less distinct. Using England's Jodrell Bank radio telescope, Astronomer Graham Smith discovered that the radio waves from pulsars are polarized, indicating that they pass through a magnetic...
...overlong and repetitious. Still, it serves to introduce the film's key character: the shining oblong, a mass of extraterrestrial intelligence that supposedly has been overseeing mankind since the Pliocene age. Now, in the 21st century, the mass has been identified by scientists, who have traced its radio signal back to Jupiter. A spaceship, Discovery I, is dispatched to that remote planet. Aboard are two conscious astronauts (Keir Dullea and Gary Lockwood) and three hibernating scientists sealed like mummies in sarcophagi. Also on board is Hal, a computer-pilot programmed to be proud of his job and possessed...
...moon, American scientists discover an identical black monolith, apparently buried over four million years before, completely inert save for the constant emission of a powerful radio signal directed toward Jupiter. The scientists examine it (touching it tentatively as the apes did) at a moment when the earth and sun are in conjunctive orbit. They conclude that some form of life on Jupiter may have placed the monolith there and, fourteen months later, an expedition is sent to Jupiter to investigate...
