Though Luna 9 successfully disposed of the hypothetical thick layers of lunar dust, said University of Arizona Astronomer Gerard Kuiper, some parts of the moon could still present a hazard to landing spacecraft. Photographs from the U.S. Ranger 9 moon probe show that between 5% and 10% of the lunar surface is covered by depressions, apparently areas of thin crust that have sagged into caves or voids under the surface. Should a spacecraft land on such a crust, he believes, it might crash through into the cave below...
...rational surface," exulted Apollo Spacecraft Program Manager Joseph Shea, "and I think the hypothesis of an oddball surface has been put to bed. There are no fundamental problems standing between us and our standing on the moon...
...Upright Landing. This minor disappointment detracted but little from the magnitude of the Russian feat. By successfully slowing an unmanned, 3,400-lb. spacecraft from an approach velocity of 6,000 m.p.h. to a speed of about 10 m.p.h., and setting it down upright on the moon's surface, the Russians proved that they had finally mastered a technique essential for a manned mission. The first U.S. softlanding attempt with the problem-plagued Surveyor will not take place before May. And even then, U.S. space scientists will not have the experience that their Soviet counterparts have gained during four...
