...first orbit, command-pilot Virgil T. Grissom and pilot John W. Young employed rockets to decrease the speed of the Gemini 3 capsule, causing it to descend into an orbit closer to the earth. The next time around, the pilots engaged rockets to push the Gemini 3 from side to side across the plane of the orbit...
Over Hawaii in the third orbit, Grissom slowed the ship for re-entry. Though Molly Brown missed her landing target by 53 miles, officials were pleased with...
...boom in Georgia, the U.S. space program ran afoul of a fizzle in Florida. At Cape Kennedy the three liquid-fuel motors of an Atlas-Centaur rocket ignited on schedule, but the missile that was supposed to toss a dummy Surveyor (soft-landing vehicle) to the moon's orbit, climbed only a few feet before a valve misfunctioned and the rocket fell back on its pad. Thin-walled fuel tanks ruptured, and more than 100 tons of liquid oxygen and kerosene burst into flames. The hydrogen-burning second stage added tons of liquid hydrogen to the holocaust...
...west, last week mounted a considerable effort to show off its growing economic strength. The Leipzig Trade Fair, celebrating its 800th anniversary, attracted an alltime-high 10,300 exhibitors, including thousands from 75 nations. The outsiders tended to agree that the most Stalinistic satellite in the Soviet orbit lately has made progress of sorts. The East Germans displayed and sold their own well-wrought machine tools, electronic devices and office equipment; they reached into their foreign-exchange reserve to order millions of dollars' worth of British trucks and a West German chemical plant. They also announced the signing...
Correct Correction. The first step toward a precision Ranger shot is to put the spacecraft on a parking orbit around the earth. That orbit is then analyzed by computers; the spacecraft's altitude, speed and direction must be measured with infinite care, for the next burst of power must boost the spacecraft through an imaginary target 120 miles above the earth and only ten miles in diameter. Only then can a mid-course correction of trajectory put the spacecraft inside the selected area...
