...PAIR of loud sonic booms shook the sky over the Atlantic Ocean last week, heralding the approach of Apollo 9 as it hurtled through the thickening atmosphere on its way home. Then, to the cheers of sailors on the deck of the helicopter carrier Guadalcanal, the heat-charred spacecraft floated down through the cloud cover and splashed into the water only three miles away. The triumphant ending to the ten-day, near-perfect mission of Apollo 9 cleared the way for the final U.S. thrust toward a manned landing on the moon...
...farmers and tradespeople in Belgium take mental patients into their homes and turn their whole town into a haven for malades? Clue: Money is not the answer. (See BEHAVIOR, "A Town for Outpatients.") - Why do U.S. astronauts feel so strongly about open communication circuits from orbiting spacecraft to earth, particularly when they are ill? (See SCIENCE, "A Spectacular Step Toward Lunar Landing...
More definitive answers will have to await the four additional Mars probes now planned by NASA. In 1971, during the next close approach of Mars, the U.S. will send two photographic spacecraft into orbit around the planet for at least 90 days each. The orbiters will take a series of pictures showing seasonal changes on Mars, map the entire surface and enable scientists to choose likely looking spots for future landings. High priority will be given to sites with the warmest temperatures and greatest traces of moisture...
...riddle of life on Mars will probably not be solved until at least 1973, when versatile "Project Viking" capsules ejected from still another pair of orbiting spacecraft are scheduled to make soft landings on the surface of the planet. In a search for any obvious evidence of life, TV cameras aboard the landers will take pictures of the immediate surroundings. Delicate instruments will sniff and analyze the atmosphere at ground level. Mechanical devices will gulp up, digest and chemically analyze Martian soil for clues to life. In their findings, relayed back to Earth by radio, man may find the exciting...
While Apollo 8 was within 4,000 miles of the earth, Alley found, the spacecraft's speed was the predominant factor; time slowed up and the astronauts actually aged more slowly than mere earthlings. But beyond that distance, as the effects of earth's gravity lessened, Apollo's time began running fast. Over the entire journey, Alley says, Apollo's time passed more quickly than earth time by the 300 microseconds...
