...serve as a rescue vehicle, on a two-year trip to Mars by the 1980s. Many scientists, noting that such a project would cost perhaps $60 billion, prefer less expensive unmanned probes beyond Mars. Last week 23 space scientists strongly urged "grand tours" of the outer planets in the mid-1970s. At that time, Jupiter, Saturn, Neptune, Uranus and Pluto will be so aligned that a spacecraft could sweep past at least three of them in a single, multibillion-mile journey. This rare planetary configuration, the panel noted, will not occur again for another 179 years...
Accordingly, by the mid-1970s the Navy and Air Force could be capable of launching a total of more than 8,000 warheads, compared with 2,700 presently...
...Nixon's third stated aim was the shakiest: "Defense of the American people against the kind of nuclear attack which Communist China is likely to be able to mount within the decade." It was a difficult line of reasoning to maintain, since the Chinese, until at least the mid-1970s, will not have the sophisticated weaponry to zero in on U.S. ICBM sites. They would be readier for the less precise task of attacking U.S. cities, which will not be defended by the Safeguard system...
...last Air Force B-52 to roll off the assembly line was completed six years ago. Ever since, the generals have been arguing for a follow-up aircraft to replace the giant bombers by the mid-1970s. Last week they won their case...
...practical preliminary step toward planetary voyages, suggested Spacecraft Center Director Robert R. Gilruth, would be to orbit a giant, cigar-shaped capsule around the earth in the mid-1970s. The big space station, said Gilruth, would be 615 ft. long, carry a crew of 100, and rotate end-over-end 31 times a minute to create an artificial gravity for those on board. Freed from the earth's atmosphere, astronomers on the station could peer through telescopes for an undistorted view of the destination of future space trips. How would this ambitious multimillion-dollar project be financed? An idea...
