...Rover (nuclear rocket) program, Seaborg said, has already tested a ground-bound model. Kiwi-A. It has demonstrated that a nuclear reactor can heat a flow of high-pressure gaseous hydrogen to proper operating temperature and can keep in operation as long as needed in a space vehicle. The more advanced Kiwi-B. which will be tested soon in Nevada, will use liquid hydrogen for its propellant...
...kind, 15 years after Hiroshima, still without any sort of international control on manufacture of atomic weapons. Unable to agree on anything else, the U.S., Russia, Britain and France have been content to rest their atomic monopoly on the prohibitive cost and inordinate difficulty of building the monster gaseous-diffusion plants and plutonium-yielding reactors in which they carry out large-scale production of fissionable materials. Now the West German scientific breakthrough appears to have smashed that barrier and opened the way to atoms for anybody with the technologists competent to handle them...
...same capacity. The present Degussa model can be built for about $1,000. and according to Zippe, it will produce in one year about one pound of U-235. Improvements already in sight will increase this figure. Both Groth and Zippe believe that centrifuges will eventually compete economically with gaseous diffusion in making nuclear fuel, enriched in U-235, for atomic power plants...
Gases to Protein. Astronomers believe that the atmosphere of the early, lifeless earth had no free oxygen in it, but was made of gases like methane, hydrogen and ammonia. Scientists have also proved that when this gaseous mixture is put in a flask with a little water in the bottom, and an electric discharge is passed through it, the chemical reaction produces an accumulation of amino acids in the water. Since amino acids are the building blocks out of which proteins are made, and proteins are the chemical framework of all life on earth, the first chemical step toward life...
Just before dawn, at an altitude of 33,000 ft., Pan American Airways Flight 2 was about 550 miles out of Tokyo, bound for Honolulu. "Suddenly I saw what appeared to be a bright star with a gaseous-appearing halo, elliptical in shape," said Captain H. Lanier Turner. "But right away I could see it was moving, and I judged it to be an ICBM, or something the Russians were trying to put in orbit...
