On a murky day a long time ago, a creature stood up and gazed at the sky to wonder at the vastness of the space. Often wandering in search of food and shelter, its mind veers off this activity to look up at the heavens. Not much has changed today even with the web of activities that man does and aerospace companies in Maryland provides an opportunity for enthusiasts to explore space.
The universe is a vast ocean of nebulae, suns, stars, planet and other space objects. Scientists say it is still expanding as observations have been made of heavenly bodies travelling further and further from the earth. Large clouds of dust occupy much of the universe. These are electronically charged particles that are in constant collision.
Forces in space cannot be fully described in words nor in mathematical formulas. All man can come up with are theories and postulations. No one can explain why galaxies do not merge and why it can stand alone in the vastness of space. The galactic system is just a microcosm of what is happening universally. At glance it appears to be static but it actually is expanding.
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 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.
Deep space has always been the realm of science fiction. Many a TV program have been produced depicting man travel into space. One movie is very popular all over the world. It features futuristic spaceships as well as other objects like the light saber. Travel is not conventional in this movie, jumping in hyperspace takes only milliseconds. Such is the imagination of man.
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.
