Getting man into orbit has already repaid the effort many times. The monitoring devices needed to keep track of astronauts' physical condition have now been adapted for U.S. hospitals, enabling a single nurse to keep track of the condition of many patients perhaps half a mile of corridors away. Today, as a result of space advances, cardiac patients may wear internally implanted electronic pacemakers. Doctors are talking confidently of birth control without pills or intrauterine devices as they experiment with a space-perfected system for monitoring bodily temperature. Refined by aerospace engineers, lasers are finding more and more uses...
...foot rope in his backyard on weekends, usually bicycled the three miles between his Houston home and the NASA Space Center. To his fellow astronauts, it came as no surprise when White took along a gold cross, a St. Christopher medal and a Star of David on his 62-orbit Gemini 4 flight, explaining afterward that they were "the most important thing that I had going...
...theories and given it a new twist that he feels will enable it to pass the mathematical and dynamical tests its predecessors failed. Physicist S. (for Siegfried) Fred Singer suggests that the moon first evolved as a minor planet, independent of the earth and following its own orbit around the sun. About four billion years ago, he believes, its path carried it on a near-collision course with the earth, which at that time was an atmosphereless orb revolving once every five hours. Captured by terrestrial gravity, the moon was pulled into an elliptical orbit around the earth, passing...
...lunar surface-only to fall back onto the moon near apogee, when the earth's gravitational force was lessened. This recurring bombardment could account for the moon's pock-marked face. Singer calculates that within a few thousand years after the encounter, the moon's orbit decayed from an elongated ellipse into a near-circular path only about 10,000 miles above the earth. At this point, it was in near-synchronous orbit...
Soon afterward, the moon's orbit began gradually spiraling outward to its present 239,000 miles. The tidal phenomena, though substantially reduced by distance, are still at work. The moon is still receding from the earth by about one inch every year. And the tidal braking effects are still at work increasing the length of the earth's day by .0018 seconds every century...
