...ship was said to have made a soft touchdown on deep snow, with the aid of parachutes. Newspapers described its flaming descent through the atmosphere and discussed the loss of radio contact when an antenna burned off. But all this is normal. It was the long silence after landing that was ominous. Then word came that the cosmonauts were safe; Yuri Gagarin, Russia's space pioneer, talked to them by telephone and reported that "they are completely healthy." Whatever had gone wrong on the last, dangerous trajectory that led back to earth had apparently not detracted from the overall...
...added Hollywood's RKO complex-which he bought from Howard Hughes for $25 million-and formed RKO General, a subsidiary that accounted for about 20% of General's 1964 profits of $37 million. Today RKO General owns seven radio and five TV stations, a community antenna television company, 123 movie theaters, Pittsburgh Outdoor Advertising, and the 400-room Equinox House in Manchester...
With the new Haystack antenna that can project a narrow beam of 8,000-megacycle, 1.5-inch microwaves that behave just like light. Dr. Shapiro plans to follow the planet Venus around its orbit, accurately measuring the time that the microwaves take to reach their target and bounce back. While Venus is well away from the sun, that time can be translated into the planet's calculated distance on its well-known orbit. But as Venus begins to swing behind the sun, the microwaves will pass through the strongest part of the sun's gravitational field. If Einstein...
...came none too soon. Besides being a guide on the way to Mars, Canopus also served to aim Mariner's directional radio antenna back toward earth, enabling Jet Propulsion Laboratory scientists to calculate the craft's flight path. Knowing that path, the rocketeers were able to plan a correction for Mariner's original course, which would have taken it past the red planet at a distance of 151,000 miles-too far for it to shoot any meaningful television pictures. But shortly before that correction could be made last week, Mariner went into an unexpected roll...
...television industry is its broadcast signals. Blocked by mountains, bothered by airplanes, bounced by hills and high buildings, they generate only ghosts on TV screens in many parts of the nation. To remedy this bothersome situation, a controversial industry has grown up across the U.S. Called CATV (for Community Antenna Television), or cable TV, it banishes ghosts and vastly increases TV reception by grabbing the signals of TV stations out of the air with towering antennas, amplifying the signals and piping them into homes by coaxial cables strung on telephone or utility poles. Serving mostly outlying areas, cable...
