Transcript of NASA

By Max, Matt and Manfred NASA Why NASA started ??? What is Apollo ??? The NASA timeline Famous NASA heroes How the NASA's rockets worked First Moon landing The reason why NASA had started was because the Americans wanted to explore what it was like on different planets.
NASA stands for:-
Agency The Apollo program is a program that is carried out by NASA it was lead after project mercury which was to man into space. NASA is to lead man on the moon the Gemini project was the technology to lead man on the moon. http://www.nasa.gov/50th/timeline.html The rockets were filled with liquid hydrogen which is an extremely flammable and is also dense Whether flying a small model rocket or launching a giant cargo rocket to Mars, the principles of how rockets work are exactly the same. Understanding and applying these principles means mission success.
In the early days of rocketry, the flight of a fire arrow or other rocket device was largely a matter of chance. It might fly; it might skitter about, shooting sparks and smoke; or it might explode. Through centuries of trial and error, rockets became more reliable. However, real advancements in rocketry depended upon a scientific and mathematical understanding of motion. That came in the seventeenth century with the works of scientists such as Galileo and Isaac Newton.
Galileo conducted a wide range of experiments involving motion. Through studies of inclined planes, Galileo concluded that moving objects did not need the continuous application of force (in the absence of friction and drag) to keep moving. Galileo discovered the principle of inertia, that all matter, because of its mass, resists changes in motion. The more mass, the more resistance.
Isaac Newton, born the year Galileo died, advanced Galileo’s discoveries and those of others by proposing three basic laws of motion. These laws are the foundation of all rocket science. Understand the laws and you know just about everything you need to build successful rockets. Apply the laws and you become a “rocket scientist.”
Newton’s Laws of Motion
In his master work entitled Philosophia Naturalis Principia Mathematica (usually referred to as Principia), Isaac Newton stated his laws of motion. For the most part, the laws were known intuitively by rocketeers, but their statement in clear form elevated rocketry to a science. Practical application of Newton’s laws makes the difference between failure and success. The laws relate force and direction to all forms of motion.
