...Since the October war, Syria has been rearmed by the Soviets even beyond its prewar strength, at a cost of $2 billion. Predictably, the result has been to bring Syria closer to the Soviet orbit and render it the most belligerent of the Arab confrontation countries...
...earth's rotation. But whether Mercury also has a liquid core is a subject of debate. Even if it does the planet probably rotates too slowly (once every 58⅔ earth days) for the dynamo effect to occur. Thus, as Mariner fell silent in its eternal orbit of the sun, it left behind a major mystery: How did Mercury acquire its magnetic field...
...star is Betelgeuse, a so-called red giant so large that it could encompass the inner solar system almost all the way out to the orbit of Jupiter. On a clear night last March, Astronomers Roger Lynds, Jack Harvey and Peter Worden took some 40 photographs of Betelgeuse, exposing each of the plates to the star's light for less than one-hundredth of a second...
...flight planners at NASA'S Ames Research Center have every reason to expect the 570-lb. nuclear-powered robot to survive the trip. If it does, it will send back closeup pictures and other data from the ringed planet. Of four Pioneers that were launched into solar orbit between 1965 and 1968 to monitor interplanetary space, all are still transmitting scientific data-even though they were designed by Pioneer's prime contractor, TRW Inc., to last only six months; only one is experiencing some difficulty with a solar sensor. Signals are also still coming from Pioneer 10, which...
...harbor some forms of life. To avoid risk of a collision that could contaminate Titan with earthly bugs, Pioneer will come no closer than 12,000 miles. Finally, the spacecraft will head out of the solar system, sending back signals that should continue at least until it reaches the orbit of Uranus (in 1985). After that the signals will be so faint that not even the largest antennas on earth will be able to pick them...
