...body of dissolved nitrogen and avoid the possibility of bends). He then entered an air lock, sealed his suit, gradually lowered its pressure to about 3 lbs. per sq. in. (so that it would be less inflated and more flexible) and only then was able to open the outer hatch and step into space, still breathing pure oxygen. By contrast, U.S. astronauts, always breathing oxygen at reduced pressures, can step directly out of their cabin into space...
...visit the Soviet Union); it would also serve as an important spur to other East-West agreements. Though the Russians have said repeatedly that no major breakthrough can come while the U.S. is fighting in North Viet Nam, lesser agreements, notably the treaty banning weapons of mass destruction from outer space, signed in ceremonies in Moscow, London, and Washington last week, can still be reached. Such contacts, said Rusk, "can reduce misunderstandings between our two countries and lead, in time, to international cooperation in areas where we are able to find common interests and mutual advantage...
Phoebe, Saturn's ninth moon, was discovered in 1898, and astronomers have been vainly looking for others ever since. Their long quest has finally been rewarded. French Astronomer Audouin Dollfus reported last week that he had found another friend for Phoebe-a tenth moon orbiting close to the outer edge of Saturn's rings...
...years. A flight launched into a proper trajectory on Nov. 1, 1979, would be picked up by Jupiter's gravity and hurled to Neptune - like a skater at the end of a crack-the-whip line - in only 8.1 years. The scientists also discovered that the outer planets would be so fortuitously positioned that a spacecraft launched on Oct. 7, 1978, could actually make a 8.9-year "grand tour," passing close to Jupiter, Saturn, Uranus and Neptune in turn and receiving a gravitational boost from each...
...using an ion engine instead of chemical fuel for deep space acceleration, Stewart believes, scientists will be able to launch outer planet probes with rockets as small as the Atlas-Centaur, or send considerably larger payloads aloft with the Saturn 5. Combined with gravity assists from the planets, the ion engines should allow sophisticated unmanned probes to give man a close look at the outer planets, regions outside the solar system - and even the sun itself...
