...sent a man into space since May 1963-when Astronaut Leroy Gordon Cooper stayed in orbit for 34 hr. 20 min. Cooper's flight signaled the end of the Mercury program and the start of the Gemini series of earth orbits in a two-man capsule. Gemini fell two years behind schedule because of technical problems and congressional heel-dragging on appropriations. This year the spacemen hope to make up for lost time: a three-orbit trip is scheduled for April, a four-day attempt for this summer, and if all goes well, there will be a week-long...
...Gemini program, which was designed to test the ability of astronauts to control a rendezvous of spaceships in orbit, had a difficult enough time even getting off the ground. But last week it passed an important milestone in the air. A Titan II rocket took off from Cape Kennedy and carried a 6,900-lb. Gemini capsule 99 miles high. No attempt was made to orbit; the capsule arched like a missile and plunged down at 16.600 m.p.h. toward a spot in the Atlantic 2,129 miles southeast of the Cape...
Project Gemini is now about 18 months behind schedule. Next step, if no more trouble develops, will be a two-man, three-orbit flight some time in April...
...stranded on a desert island, have completely forgotten the value of the earth's mass. Desirous of launching a geodisic earth satellite into orbit, you wish to know this quantity accurately. Having only a fully equipped physics laboratory at hand, describe how you would be about measuring the earth's mass. Answer this intriguing question concisely...
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...
