...headlines, and for the moment at least, most of the argument about whether the moon program is worth its cost was forgotten while the nation joined in the cheering. "This is a great day for science and a great day for the U.S.," exulted University of Arizona Professor Gerard Kuiper, head of a team of scientists at Caltech's Jet Propulsion Lab, which prepared the shot. From all over the world flowed praise. "A stupendous achievement," said Kenneth Gatland of the British Interplanetary Society. Even Moscow joined the chorus...
Zoom. First to get a look at the pictures was a committee of scientists headed by Astronomer Gerard P. Kuiper of the University of Arizona, a man who has spent much of his life peering at the moon through the world's best telescopes. "What has been achieved today is truly remarkable," he announced. "We have made progress in resolution not by a factor of 10, or 100, which would have been already remarkable, but by a factor of 1,000. The moon, which a good telescope can bring to a distance of 500 miles, has been brought...
...Then Kuiper exhibited a series of ten lunar photographs. The first showed a section of the Sea of Clouds about 78 miles square. It was taken when Ranger was still 470 miles away, and Kuiper said that it showed just about as much detail as the best photographs obtainable with the biggest telescopes on earth. Picture by picture, as the spacecraft sped toward the moon, the scene expanded. Craters seemed to blossom on lunar plains that had looked perfectly smooth; in the next pictures even smaller craters appeared...
...cluster of pits showed up with edges that did not look as jagged as those of most lunar craters. As Ranger dropped lower, the clustered craters grew, and one of them showed black dots inside its rim. Nothing of the sort, said Kuiper, had ever before been seen on the moon. His guess was that the pits were made when a giant meteorite hit the moon and dug the conspicuous crater Copernicus, which is surrounded by "rays" that are believed to be splashed-out material. Astronomers used to think that this material was some sort of dust, but Kuiper...
...when Ranger was about 1,000 ft. above the surface, and before impact the scanning beam had time to transmit only a part of it-an area 60 ft. by 100 ft. There, sharp and clear, were tiny craters no more than 3 ft. across. Careful study, said Dr. Kuiper, would almost surely show objects half...
