The History of American Space Travel

Beschreibung / Inhalt
Das Dokument beschäftigt sich mit der Geschichte und Theorie der amerikanischen Raumfahrt. Es werden verschiedene Theorien und Pioniere der Raumfahrtgeschichte vorgestellt, wie zum Beispiel Johannes Kepler, Isaac Newton, Konstantin Ziolkovsky, Robert Goddard, Herman Oberth und Wernher von Braun. Die Rolle der Wissenschaftler und Ingenieure bei der Entwicklung von Raketen und dem erfolgreichen Start in den Weltraum wird beleuchtet. Zudem wird das Zentrum der Schwerkraft als wichtiges Prinzip beim Bau eines Raumschiffs erläutert. Das Dokument soll einen Einblick in die Entstehung und den Fortschritt der amerikanischen Raumfahrt geben.

The History of American Space Travel The earth is the cradle of mankind one cannot remain in the cradle forever Konstantin Ziolkovsky If you talk about space travelling you think about projects like Apollo 11, or futuristic films like Star Trek or something in this direction. You will think about the Mir or the Challenger. Every of those projects has to do with space travel and I will try to bring you the history of the American space travel near. I will write about the Mir too because it s very up to date at the moment. But first of all I ll write about the beginnings of space travelling and about the basic theories. Working out the Theory: To design and build a spacecraft, you need to be able to figure out how big to make it, how heavy it can be, how fast it will have to go, how much fuel it needs and so forth. For that, you need a theory of how objects move in space and how to make the calculations. Three brilliant men worked out almost all theory of space flight over a period of nearly three centuries - from 1600 to 1900 Johannes Kepler: Was the German mathematician who, in 1609, figured out the equations for orbiting planets & satellites? In particular, he determined that the planets move in ellipses (flattened circles) rather than true circles. Isaac Newton: In 1687 he wrote what is probably the single greatest intellectual achievement of all time. In a single book he established the basic laws of force, motion, and gravitation and invented a new branch of mathematics ...
