...Colorado, is the greatest single producer of solar data, vital to IGY research in solar-terrestrial phenomena, such as aurorae and magnetic and radio-transmitting effects. In addition, University and Smithsonian personnel made significant contributions to the IGY in the fields of oceanography (the Geology Department and graduate students), meteor work (the Astronomy Department and Smithsonian), and upper atmosphere studies (mainly Smithsonian...
Controversial Moon. The moon is an exception. It is so close that it shows a wealth of detail that astronomers have studied for centuries. They have also argued bitterly over many questions presented by its serene face, e.g.: Are the ring-shaped craters the result of volcanic activity or meteor impacts...
...thrust, the 80-ft. beast leaped from its Cape Canaveral pad, rocketed off the Florida coast into the starry night and arched serenely over the moon. The Cape's missile watchers held their breath as, in shucking its booster motors, the ICBM blazed like a meteor 200 miles from earth; then it faded and seemed to hang for a long time, suspended, like a star-colored point, just below Orion...
Kohman rejects both these theories. He analyzed tektites and found that they contain considerable amounts of radioactive isotopes (beryllium 10 and aluminum 26) that are formed by cosmic rays in space. This rules out the moon, he says. If tektites were splashed out of lunar meteor craters, they would have to come from at least a small distance below the moon's surface, where they would be sheltered from rays...
...tektites in each of the patches, which are hundreds or thousands of miles across, are different, and none of them have any relation to the earthly rocks near them. One popular theory holds that they are chips knocked off the moon by meteor impacts. Another argues that they are nonmetallic meteorites intercepted in loose swarms that melted into a kind of glass when they hit the atmosphere...
