...series of pictures that Ranger sent home from its final dive began with a view of the Crater Alphonsus and its neighbors, a picture that just about matched the best that have been taken by the biggest telescopes on earth. Then, as the spacecraft plunged toward its impact point, the lunar landscape expanded. Slowly at first, then faster and faster, the field of view narrowed (see cuts), and details emerged that had never before been glimpsed by human eyes...
Faster and faster fell Ranger IX, tugged by the moon's gravitation until it reached the speed of nearly 6,000 m.p.h. Its cameras never faltered. They sent their pictures to the end, giving countless millions of televiewers a look at the crater floor as it might be seen from the cockpit of a spacecraft about to land. The last pictures were transmitted just .45 seconds before impact from three-quarters of a mile above the lunar surface. They showed objects as small as ten inches...
...Tranquillity was the target picked before the launch. Ranger VII had photographed a fairly smooth-looking place now called the Mare Cognitum (Known Sea) and found it to be pocked with small pits apparently made by chunks of rock tossed out of the crater Copernicus. A lunar landing vehicle might have serious trouble with such pits, and the hope was that the Sea of Tranquillity would prove to be smoother...
...youthful novels) only three books of verse, containing fewer than 100 poems. The Less Deceived, published in 1955, was the blazing eruption of a young volcano, the work of a brilliant man discovering in disorder what he could do. The Whitsun Weddings is a prepared descent into the simmering crater of middle age, the work of a mature man discovering systematically...
...best Ranger photographs, explained O'Keefe in teh magazine Science, show a region covered by broad, light-colored streaks radiating from the craters Copernicus and Tycho. These rays are believed to be dust and fragments tossed out by teh meteor impacts that blasted the two craters, and since they lie on top of most other lunar features, they are listed among the youngest parts of the moonscape. But O'Keefe also found a conspicuous black mark showing starkly against the lighter background of one of Tycho's rays. The ray had not dusted the mark with light...
