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.
Within galaxies are systems that are mostly dominated by huge stars that exert a pull on other objects. The forces make it orbit around the sun in fixed paths. The system is scientifically termed as a solar system. This system basically is a huge star with several planets revolving around it. Other objects not of the system travel through it in cycles.
Earth is but a tiny speck in the scheme of things. It is like a grain of sand when placed in context of Universal vastness. But it does harbor life both plant and animals and many more. The ground is where most of these are found and beasts habituate in the great forests and woodlands. The oceans surround the dry land is home to the fishes.
Flying like a bird has always been an ambition of man. It came to fruition with the invention of airplanes. The early models had wings shape like that of bird. Many an adventurer has been killed in flimsy flying machines. A huge step in the history of flight was the development of a lightweight engine that could be mounted on a frame and have enough power to achieve flight.
Rapid advances in technology made the engine more efficient and light. The engines spun the air screws that push or pull the frame forward and into the skies. At the start the bodies of airplanes were of canvasses that were plastered over a frame. Modern airplanes now use metal for the most part. Synthetic materials are also utilized to make it lighter.
During world war two one nation created the jet engine. This revolutionized the aircraft industry. It was light weight and was more powerful than conventional engines. It was capable of making thrusts that could reach the speed of sound. Most commercial and military airplanes at present use this engine in its various forms. Two examples are the ramjet and the turbojet.
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.
