Space exploration is the use of astronomy and space technology to explore outer space. Physical exploration of space is conducted both by human spaceflights and by robotic spacecraft.
While the observation of objects in space—known as astronomy—pre-dates reliable recorded history, it was the development of large liquid-fueled rocket engines 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/strategic advantages against other countries. Various criticisms of Space Exploration are sometimes made, generally on cost or safety grounds.
Space exploration has often been used as a proxy competition for geopolitical rivalries such as the Cold War. The early era of space exploration was driven by a "Space Race" between the Soviet Union and the United States; the launch of the first man-made object to orbit the Earth, the USSR's Sputnik 1, on October 4, 1957, and the first Moon landing by the American Apollo 11 craft on July 20, 1969 are often taken as the boundaries for this initial period. The Soviet space program achieved many of the first milestones under Sergey Korolyov and Kerim Kerimov, including the first human spaceflight (Yuri Gagarin aboard Vostok 1) in 1961, the first spacewalk (by Aleksei Leonov) in 1965, and the launch of the first space station (Salyut 1) in 1971.
After the first 20 years of exploration, focus shifted from one-off flights to renewable hardware, such as the Space Shuttle program, and from competition to cooperation as with the International Space Station. From the 1990s onwards, private interests began promoting space tourism. Larger government programs have advocated manned missions to the Moon and possibly Mars sometime after 2010.
space exploration...?*
Q. is ita. necessary in a world with a rapidly expanding population, heading towards self destructionb. a complete waste of money, resources and brain power which could be put to better use here on earthc. a race between countries/corporations to find something somewhere to own and exploitgravy ba. I'm 37b. why would I think you're a conformist? I know nothing about you.c. all the US won was the race to the moon and a few thousand photographs. Oh yeah, and aliens abducting Cletus. The Soviets were first for everything else...first object/creature/man in space, first orbit of the moon...and in a few years the Chinese are gonna wipe the skies with NASA...so go have a cheeseburger and calm yourself down.

A. I would say a mix between A and C. There is a little bit of Ego going on between the countries trying to prove they can do one better than the other in regards to space flight. However, with an increasing population it is natural for us as humans to want to explore uncharted territory to expand our race, and to find more resources we need to survive once ours are depleted. We need to find new land to accomodate our ever growing population. It's also a natural curiosity for us to explore the unknown. There is a reason they call space the final frontier.

A. Space: provides communications: television, internet and mobile phone service throughout the world. Satellites are crucial for weather forecasting.You may or may not be familiar with Barringer Crater in Arizona. It's where an meteorite hit. We need to go back into space and catalog every object that could hit us. Deep Impact is a movie, but the basic idea of a large space object hitting the earth is true, although the probability is very low in any given year. Given that an impact is thought to have caused the extinction of the dinosaurs, the costs of being ill-prepared are quite high.

A. they have been investing in engineering and mathematics education since the rise of communism, which you could technically factor into the price they have spent on the space program.. it's probably on par with America since they are also planning to go to mars.. their plan is a ltitle different from america tho, whereas we are going to do the training by doing more moon missions, they are going to send me to orbit mars (not land) and study the affects of prolonged weightlessness, and possible gravity creating procedures... not to mention radiation shielding and a whole host of other things...
