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. However, the first man-made objects to reach space were Nazi-Germany's V2 rockets, used as early as the Second World War. 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 and now private space exploration of the Moon (see GLXP). In the 2000s, China initiated a successful manned spaceflight program, while Japan and India also plan future manned space missions. Larger government programs have advocated manned missions to the Moon and possibly Mars sometime after 2010. From Wikipedia under the

Asked by Roxane - Fri Jun 5 00:40:38 2009 - - 4 Answers - 0 Comments A. Your question is pretty similar to an essay question on my AP lang and comp test. Space exploration satisfies our curiosity probably more than anything. The first picture of the earth (Earth Rise) helped kick start the environmental movement in the 70s and Earth Day. As you can imagine, the picture packed a powerful punch. Studying other planets in the universe helps us understand our own planet. For example, one of Saturn's moons has conditions very similar to what scientists think Earth looked like in its early days. So by studying this moon we can speculate and understand more about the beginnings of our own Earth. As for the money, you must realize that its actually NOT that much money. Out of a dollar, less than about 6 cents (i… [cont.] Answered by Moon - Fri Jun 5 01:07:28 2009 Why don't any of the Presidential candidates have plans for space exploration? Q. Not one has spoken of plans for NASA for space exploration. Asked by Agent Fox - Mon Jan 28 22:36:00 2008 - - 13 Answers - 0 Comments A. As the other responders stated, the U.S. has many burdens that need attention. Spending billions on space exploration is a tough pill to swallow. Unfortunately, until our elected officials see the benefit in "tapping" fuel and energy sources off this planet, nothing is going to be done. It's obvious to me that eventually, the Earth will not be able to sustain human life, if we continue to deplete our natural resources at the pace we are today. Without space exploration, we're going to run into rough times and we're not going to be stop the damage that is spiraling out of control. Space exploration gives humanity hope for the continuance of human life and for supporting the needs of our civilization. If we're to take advantage of what… [cont.] Answered by pic_exec - Tue Jan 29 00:16:40 2008 Whats the next step in space exploration?
Q. Will we send somebody to Mars in the near future? Will there be a city in space in the next 50 years? whats the next great feat to happen in space exploration? Asked by coolguy3721 - Tue Jul 17 13:14:07 2007 - - 6 Answers - 1 Comments A. The next step is to have representetives from the "alien" life forms to come over and meet our stupid leaders.
