...China's military might, but the emphasis was defensive. "On the vast land of China, wherever you go," he warned possible invaders, "there will be your burial ground." Lin made no mention of the fact that China had set off its first underground nuclear explosion and tested a hydrogen bomb in the atmosphere just before the anniversary...
...Peking has an estimated 100 nuclear devices, including hydrogen bombs, but it is only now developing and testing the medium-range missiles needed to deliver them. Tokyo's Asahi Shimbun reported that the Chinese had conducted an underground nuclear test early last week; the U.S. Atomic Energy Commission had no comment...
ized bacteria or other signs of ancient life. Fireman is analyzing the radioisotopes of helium, argon and hydrogen to determine the effects of the solar wind-a stream of high energy particles from the sun-on the lunar rock...
...dust, they made several more interesting discoveries. Geochemist Oliver Schaeffer, seeking to determine what gases are expelled from the sun as solar wind, heated a pinch of moon dust to 3,000° F. Analyzing the escaping gases, he found that the lunar surface had absorbed considerable helium and hydrogen from the sun. But he also noted surprisingly large amounts of such rare gases as argon, neon, krypton and xenon, which suggested that the moon may prove a promising solar observatory. At California's Lick Observatory, astronomers were finally able to get a reading on the distance between earth...
...proverbial pig's squeal could be used. Water vapor steaming out of the heated rocks could drive power turbines before being condensed into drinking water. When lunar water is finally available in ample supply, it could even be used for rocket fuel. Moon technicians will decompose it into hydrogen and oxygen gases by electrolysis, then feed the gases into a lunar cryostat, a device that can reach extremely low temperatures during the chill lunar night without using power. The resulting products would be liquid hydrogen and liquid oxygen, familiar space-age fuels...
