الصفحة vii - The preservation of the role of the United States as a leader in aeronautical and space science and technology and in the application thereof to the conduct of peaceful activities within and outside the atmosphere...
الصفحة 35 - 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. No single space project in this period will be more exciting, or more impressive, or more important for the long-range exploration of space; and none will be so difficult or expensive to accomplish.
الصفحة 31 - Mercury we expect to learn much about how man will react to space flight, what his capabilities may be, and what should be provided in future manned spacecraft to allow man to function usefully. Such knowledge is vital before man can participate in other, more difficult, space missions. But the determination of man's capabilities is only one of the objectives of Project Mercury.
الصفحة 5 - Almost all the matter of the star is ejected into space by the explosion, including the heavy elements the star has been manufacturing during its lifetime. After the explosion these heavy elements mix with the hydrogen gas in •••the space between the stars, and in the course of time new stars condense from the enriched mixture of gas and dust, as we described previously.
الصفحة 146 - Conference tentatively scheduled for the latter part of 1963 to consider the allocation of frequency bands required to support both research and operational phases of the various categories of space radio communication...
الصفحة 45 - ... body shapes such as missile nose cones but we run into considerable trouble in predicting the behavior of more complicated shapes having lifting and control surfaces and return with orbital or higher than escape speeds. The eternal problem, of course, is that of heat. The tremendous kinetic energy has to be converted into other forms of energy? mostly mechanical and heat energy, to slow the body down and during this time to make the vehicle immune against melting, burning, and other structural...
الصفحة 9 - They produce communications blackouts, magnetic storms, and auroral displays; and they also produce violent changes in the intensity of the Van Allen belts, which are apparently related, in a manner not yet clearly understood, to the other atmospheric effects that accompany solar flares. The entire matter of Sun-Earth relations, including the formation of the Van Allen belts and their possible role in geophysical phenomena, constitutes a relatively new area of research in the space sciences. It is...
الصفحة 8 - Moon and planets must have been molten at an earlier stage in their histories. In that event, the iron in their interiors would melt and run to the center to form a dense core. Another theory holds that the planets were formed out of pockets of condensation in the dust surrounding our Sun during the early stages of its lifetime.
الصفحة 145 - NASA, which also has a significant role in the research and development work on communication satellites. The Commission and NASA, cognizant of the need for mutual cooperation, have jointly signed a memorandum of understanding, setting forth certain conditions of fact and policy guidelines. Each has agreed that the earliest practicable realization of a commercially operable communication...
الصفحة 45 - ... vehicle passes ; solar pressure; thrust application; and others. In our research we have sought to simplify the analytical procedures for defining these complex curves in space and to determine the implications of these paths with respect to navigation and guidance and corrective thrust requirements. For example, recent studies of a lunar circumnavigation flight, with return to Earth, show that certain trajectories will reduce the miss distance at the Earth, and in turn the power required for...
