Luigi G. Jacchia, lecturer on Astronomy, has predicted that the 31-pound satellite will fall from orbit in April 1970, much later than Wernher von Braun and other rocketry experts predicted when the satellite was launched...
After more than 12 years in earth orbit, Explorer I, the first U.S. satellite, will reenter the atmosphere and burn sometime next Spring, a Harvard astronomer has estimated...
Explorer I originally achieved an orbit that ranged from 219 to 1587 miles above the earth's surface. But as a result of friction with the atmosphere--extremely thin at those heights--the spacecraft's altitude slowly dropped. When a satellite's speed decreases from orbit to orbit, it cannot counterbalance the earth's gravitational field and slowly loses altitude...
...Space" is a song about being spaced-out. It starts slowly, as a stoned-steady guitar beat reverberating through an echo chamber accompanies the cool voices that weave in and out. "My body is walking in space/ My soul is in orbit with God, face to face," the eerie voices tell us, and we can believe in their moonglow-bathed hallucinations. But no sooner is the mood established, than composer Galt Mac Dermot and lyricists Gerome Ragni and James Rado destroy it by tipping their hats to the Times Square crowd. All of a sudden the chorus hippies are yelling...
Singer concedes that Phobos and Deimos could be explored by visiting spacecraft. But if little Deimos, only five miles in diameter, could be brought into earth orbit, it could be investigated more thoroughly. The technology of the interplanetary move, which would be man's first rearrangement of the solar system, would be simple, Singer says. An efficient, low-thrust nuclear engine capable of firing for long periods of time could be set up on Deimos to push the moonlet out of its orbit and start it curving toward the earth. The cost would be high, says Singer...
