Scientists in both countries have been urging joint space ventures to save money and pool information. That now becomes a reality as plans go forward for a 1975 rendezvous in orbit of American and Soviet space ships (see story, page 19). The two countries agreed to pool research and resources in the medical and environmental fields. Though the U.S. no doubt has more to offer, Russia has apparently made strides in producing experimental anti-cancer drugs and in coping with urban sprawl. The U.S. and the U.S.S.R. also agreed to stop harassing each other's fleets on the high...
...Soviet Union that claims to be embarked upon that purest of Communist crusades, a national war of liberation. On ideological grounds, Hanoi clearly qualifies for an extraordinary amount of comradely assistance, and has received it partly because Russia wants to keep North Viet Nam out of Peking's orbit of influence. But an overly harsh Soviet reaction would imperil its more important prospects of improving relations with the capitalist West-and might lead to a military showdown with the U.S. in a part of the world where geography does not work to Russian advantage...
...Arizona's Lowell Observatory, discovered the last and outermost of the solar system's nine known planets. But many astronomers have never given up hope of finding a tenth planet even farther from the sun. They have been encouraged in their search by irregularities in the orbit of the eighth planet, Neptune, which some suspect could be caused by the gravitational tug of a mysterious "Planet X." Until now, however, all efforts to sight Planet X have failed...
...current position in the heavens. His "discovery" was made, not by scanning photographic plates, but by analyzing the erratic behavior of Halley's Comet, which comes into view every 76 years (next appearance: 1986), as it nears the sun in its elliptical and far-ranging orbit...
...four years, Brady fed into a computer mathematical models of a ten-planet solar system, seeking the characteristics of a still undiscovered planet that would cause the irregularities in the comet's orbit. Gradually the description of Planet X emerged: it would be three times as massive as Saturn (second largest of the planets) and nearly 6 billion miles from the sun (more than half again as far as Pluto). It would take 464 years to complete a single trip around the sun, and the plane of its orbit would be tilted an angle of approximately 60° from...
