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 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.
Other forces were also in play during this event, from where it came from nobody really knows. What is known is that huge masses that were created exerted gravity that pulled other objects to it. The galaxy is a child of this explosion and is home to millions of stars, suns, and planets. This system is spiral in form and is murky hence the name Milky Way.
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.
A flimsy flying machine was the first manifestation flight desire. To be free from the ground like a bird is an event that everybody dreams about. The first contraptions had engines in its early stages and could not provide enough power to lift the contraption which composed of light materials like cloth and wood.
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.
People say that the last frontier is space. Nations have space programs with the purpose of exploring space beyond earth. Rich and powerful nations have place men into orbit around the earth using rocketry to thrust the vehicles free from planetary gravity and atmosphere. Satellites are launched into space using rockets, so far it is the only way to hurl huge object into the sky.
