Space exploration is the discovery and exploration of outer space by means of space technology. Physical exploration of space is conducted both by human spaceflights and by robotic spacecraft. While the observation of objects in space, known as astronomy, predates reliable recorded history, it was the development of large and relatively efficient rockets during the early 20th century that allowed physical space exploration to become a reality. Common rationales for exploring space include advancing scientific research, uniting different nations, ensuring the future survival of humanity and developing military and strategic advantages against other countries. Various criticisms of space exploration are sometimes made. The Importance of Space Exploration
Outer space is the provider of an endless source of questions for scientists. Its enormous proportions are seemingly endless and interesting, and the knowledge garnered on the subject is very commonly well received by the supporting public. Nowadays in a time where economic recession is threatening to cut the funding necessary for space travel, how can we justify it? On the positive side of things, space exploration helps scientists answer a lot of earths' questions. That is a definite pro. Space exploration has proven immensely helpful in determining the theories of where earth came from, like the Big Bang. It also helped scientists single out what elements need to be present for an environment to sustain life. This can prove invaluable, especially if humans do end up completely destroying earth. We need that knowledge in order to find a new planet, right? Hopefully it won't come to that. Space explorations' biggest pro is that it has given scientists content and examples to compare our earth to. This makes it easier to answer questions that would prove to be almost undecipherable otherwise, without thousands if not millions of years of study. Also, the invention of technology used in space exploration was...
