The explorer nature of man forever will be the catalyst for space exploration. This creature is so fascinated with the heavens that it long to go there, to explore and to know what goes on in other heavenly bodies like the moon. Modern man still seeks to conquer the stars. Advance scientific vehicles are now being developed at by aerospace companies in Maryland.
The vastness of time and space cannot be measured. Various theories have been proposed as to its beginnings. The most prominent is the big bang theory. A big cosmic explosion happened trillions of years ago the flung particles into deep space. The speed with which the particles were flung was so forceful that collisions fused them together.
Galactic expanse can be deemed as smaller than that of the universe for it but an occupant. These huge conglomerations of stars may differ in form depending on how forces in outer space work. The gravitation force exerted by this system is strong enough to pull in objects and to repel other forces from swallowing it.
A Star or a sun is the centerpiece of a solar system. The gravitational pull that it exerts makes planets go around it constant circular path. Earth is one planet that orbits around its sun which is ninety three million miles away. It is a burning cauldron of hot gasses that feed each other making it last for billions of years.
Earth is a small planet and is one that can support life. The surface is made of solid matter that stands as foundation of land and the seas. The biosphere contains elemental gasses like oxygen. Another layer next to the core is heated magma rocks and the core is made up of densely pack solid material that is electromagnetic.
Man has always been interested space travel. As it watches feathered creature fly in thin air, it desires to do the same. To feel what a bird experiences while in flight. Several attempts were made in the past to replicate the flight motion of an avian so man can fly. The first successful human flight was accomplished during the early part of the twentieth century, in the form of the first airplane.
This contraption has evolved tremendously over the years. Races were organized that stimulated rapid development. Early models were made of fabric and wood. Today almost all are constructed of metal in its various states. Developments in engine technology also hastened the modernization of aircraft. Originally these were propeller driven and powered by engines mounted in the framework.
The jet engine was simultaneously developed by two nations. These did have no propeller attached to it, instead, it uses air that is sucked the engine and blown out at the other end. It was more powerful and more fuel efficient that it can make an airplane travel at more than five times the acceleration of sound. Military and commercial aircraft have engines of this type.
Fully developed nation are the richest on the planet and are the only ones that can afford to fund a space program. The most powerful nation on earth embarked on this endeavor and have successfully transported man to the moon. This costs billions of dollars in terms of planning, organizing, coordinating, and managing the program. This was principally funded by government.
