Liquid hydrogen is the most effective rocket fuel ever developed. Some 40% more powerful than the kerosene fuel used in the Saturn booster, it will place the Apollo spacecraft in earth orbit, then be used again in the same flight to hurl the spaceship toward the moon. The trouble is, its virtues are not bought cheaply. Its extreme volatility and the - 423° F. temperature necessary to keep it in liquid form make it difficult to deal with both on the ground and in space. NASA spacemen had theorized that once weightless in orbit, liquid hydrogen would scatter around...
...ethic of that ancient oath "by Apollo the Physician" is one that all doctors have sworn to and still swear by. Do they live up to it? Not always, is the grim conclusion of Harvard's Dr. Henry K. Beecher after a ten-year study of medical experiments recently performed on human subjects. Dr. Beecher has no quarrel with the physician who tries a new drug or a new operation for the benefit of a patient; he is concerned about experiments that are designed for the ultimate good of society in general but may well do harm...
...lunar terrain. At a Washington press conference, they announced that the moon's surface pre sented no great obstacles to a manned lunar landing; its consistency is almost earthlike, and its bearing strength -about 5 Ibs. per sq. in.-is more than enough to support the weight of Apollo's Lunar Excursion Module. "In one sentence," said JPL Project Scientist Leonard Jaffe, "the moon surface looks like a soil, not very hard, with rocks and clods...
...their second rendezvous, the astronauts maneuvered to a point 13 miles below and behind the ATDA, then again effortlessly closed the gap, using only an on-board computer and a handheld sextant. Next, to simulate an emergency rendezvous during the actual Apollo moon flight, they moved Gemini eight miles above and 86 miles ahead of the ATDA, then attempted to close in again with the aid of ground controllers. This time they ran into trouble-losing sight of the ATDA against the confusing background of the earth below, consuming eleven hours and 30 extra pounds of fuel before accomplishing...
...demonstrate their confidence that the U.S. space program will continue on schedule, they designated Space Veterans Virgil Grissom and Edward White and Rookie Roger Chaffee as crew members on the first three-man U.S. space mission-an earth-orbiting flight late this year in the Apollo moonship...
