الصفحة 10 - I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to earth.
الصفحة 36 - Chaffee were suited up in the command module, moving through the countdown toward a simulated launch. At T-minus-10 minutes tragedy struck without warning. As Maj.
الصفحة 15 - Grissom was hoisted to safety in a rescue helicopter. In September the unmanned Mercury-Atlas combination was orbited successfully and landed where it was supposed to, east of Bermuda. On 29 November the final test flight took chimpanzee Enos on a two-orbit ride and landed him in good health. The system was qualified for manned orbital flight. And on 20 February 1962, Astronaut John H. Glenn, Jr., became the first American to orbit the Earth in space. Friendship 7 circled the Earth three times; Glenn...
الصفحة 10 - Now it is time to take longer strides — time for a great new American enterprise — time for this nation to take a clearly leading role in space achievement...
الصفحة 1 - In August President Eisenhower nominated T. Keith Glennan, President of Case Institute of Technology and former Commissioner of the Atomic Energy Commission, to be the first Administrator of the new organization, NASA, and Dryden to be Deputy Administrator. Quickly confirmed by the Senate, they were sworn in on 19 August. Glennan reviewed the planning efforts, approved most. Talks with the Advanced Research Projects Agency (ARPA) identified the military space programs that were space-science oriented...
الصفحة 54 - Mariner 9 was launched; on 10 November, the first American spacecraft went into orbit around another planet. The early months in orbit were discouraging; a gigantic dust storm covered most of the Martian surface for two months. But the dust gradually cleared; photographs in 1972 showed startling...
الصفحة 55 - September 1971, was the first satellite to catch on film the beginning of a solar flare and the consequent streamers of hot gases that extended out 10.6 million kilometers; it would also discover "polar ice caps" on the sun — dark areas several million degrees cooler than the normal surface temperatures. With the confirmation of black holes, the enigmatic collapsed star remnants so dense in mass and gravity that even light cannot escape, and the previous discoveries of quasars and pulsars, these...
الصفحة 51 - NASA, 1915-1980 lunar landing combination blasted out to lunar distance. Once in lunar orbit, the crew separated the lunar module from the command module, descended to within 14 kilometers of the surface, fired the ascent system, and docked with the command module. Now all systems were "go.
الصفحة 60 - ERTS 2} was orbited ahead of schedule to ensure continuation of the data that ERTS 1 (renamed Landsat 1} had provided for two and a half years, and a third satellite was programmed for launch in 1977. This would give confidence to experimental users of the new system that they could securely plan for continued information from the satellite system. The Earth-resources program had another important meaning. It was a visible sign that the nature and objectives of the space program were undergoing a...
