Dutch-born Astronomer Gerard Kuiper (rhymes with hyper), head of the University of Chicago's Yerkes and McDonald observatories, thinks the moon was formed at the same time as the earth (5½ billion years ago), but at first it revolved only about 20,000 miles from the earth's surface. Beyond it were a lot of smaller satellites arranged in a disk somewhat like the rings of modern Saturn...
Crunchy Snow. After this climactic event Astronomer Kuiper thinks the moon led an increasingly peaceful life. It picked up the rest of the small satellites, which made the fresh-looking pits on its surface. Cosmic rays and other high-speed particles bombarded its surface, riddling the material with microscopic holes. This beaten-up stuff is only an inch or so thick, says Kuiper, and it is not dust. He thinks it would feel underfoot "like crunchy snow...
...moon's flat maria (waterless "seas") are almost certainly covered with lava that poured out on the surface billions of years ago, said Astronomer Gerard Kuiper of Yerkes Observatory. In those days, Kuiper told the astronauts at Denver, the moon's interior was kept liquid by radioactivity, so any disturbance, such as a large meteor impact, was likely to cause an upwelling of lava. Kuiper thinks that smooth places on the maria will make firm landing spots for earth's spaceships...
...eyepiece of the telescope that towered through the observatory roof and spied on the moon. His voice echoed in the empty chamber. "Now, I note about twelve impact craters, and the largest of these I shall mark on the map with an A." said Dutch-born Dr. Gerard Kuiper head of the University of Chicago's Yerkes Observatory. By such sharply focused glimpses of scientists at work, Conquest (CBS) started to live up to its promise as a $1,000,000 series of ten science programs that will stretch into next season. After a talky start, the hour-long...
...Cecilia H. Payne-Gaposhkin, chairman of the Astronomy Department, commented yesterday that direction and the shapes of the orbits of Neptune's satellites indicate that they have had an "exciting adventure." She termed Kuiper's theory "plausible, but not certain by any means...
