Page 135 - 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.
Page 102 - ... stations is limited, when the satellites are in orbit at low altitude. Consequently, to get continuity of transmission between the two terminals, a number of satellites must be put into orbit, and these must be so distributed in space that at all times, at least one can be used as a communication link between the terminal stations. A realistic appraisal indicates that unless fairly complex provisions are included for controlling the position of the individual satellite in its orbit, it must be...
Page 110 - Data from the solar sensor is transmitted to the ground and there a control signal is computed which will activate the positioning gas Jet in the side of the satellite. This force will slow the satellite down or speed it up in its orbit, depending upon the direction in which the Jet is pointed when it is operated. This controllable Jet can be used to reposition the satellite from its original injection point close to the African...
Page 269 - In July 1957, while project officer of the F8U, he set a transcontinental speed record from Los Angeles to New York, spanning the country in 3 hours 23 minutes.
Page 110 - The gryoscopic effect holds the axis of the satellite in the attitude with which it was separated from the Delta booster, so that when, through either ground control or by proper timing, the apogee rocket is fired, the satellite will be injected into a circular orbit. At this time the attitude control jet in the end of the satellite can be actuated by ground control to provide a force to turn the satellite. The result of this operation is indicated in this view.
Page 260 - It is very much the same in learning to ride a flying machine; if you are looking for perfect safety, you will do well to sit on the fence and watch the birds; but if you really wish to learn, you must mount a machine and become acquainted with its tricks by actual...
Page 105 - ... far as the passive reflector communications system is concerned. One of these is a sphere which has been lightened by etching holes in the metallic foil which constitutes the reflecting surface. This reduces the weight and makes it possible to orbit a larger satellite, which will have correspondingly improved performance, with the same launch vehicle. An alternative method of reducing the weight of the sphere is to make the sphere of an appropriately sized wire mesh. We are not sure at this time...
Page 104 - Having discussed some of the reasons for the different orbital configurations proposed for communications satellites, let me now review the satellites themselves. Basically, the simplest of all the communications satellite techniques is the passive reflector — the radio mirror in the sky. The passive reflector can take many forms and over the years a number of specific configurations have been suggested. At the present time NASA is investigating four of these configurations, as they appear to have...
Page 269 - He was graduated and commissioned in the Marine Corps a year later. After advanced training, he joined Marine Fighter Squadron 155 and spent a year flying F4U fighters in the Marshall Islands. During his World War II service he flew 59 combat missions. After the war he was a member of Fighter Squadron 218 on North China patrol and had duty in Guam. From June 1948, to December 1950, he was an instructor in advance training at Corpus Christ!.
Page 260 - Now, there are two ways of learning how to ride a fractious horse: one is to get on him and learn by actual practice how each motion and trick may be best met; the other is to sit on a fence and watch the beast a while, and then retire to the house and at leisure figure out the best way of overcoming his jumps and kicks.
