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, predates 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 and strategic advantages against other countries. Various criticisms of space exploration are sometimes made. 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, including the first living being in orbit in 1957, the first human spaceflight (Yuri Gagarin aboard Vostok 1) in 1961, the first spacewalk (by Aleksei Leonov) in 1965, the first automatic landing on another celestial body in 1966, 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 and then private space exploration of the Moon (see GLXP). In the 2000s, China initiated a successful manned spaceflight program, while the European Union, Japan, and India have also planned future manned space missions. The United States has committed to return to the Moon by 2018 and later Mars. China, Russia, Japan, and India have advocated manned missions to the Moon during the 21st century, while the European Union has advocated manned missions to both the Moon and Mars during the 21st century.

GNU Free Documentation License Do you think space exploration is worth the cost? Q. I was just wondering if you think space exploration is worth the money. Please include the reason of your opinion... Thanks! Asked by swimchick - Wed Mar 31 22:36:28 2010 - - 1 Answers - 0 Comments A. It is worth the cost. I feel that mankind cannot stay confined to earth forever. Eventually we will not have enough resources to support all the humans on earth. If somehow humanity survives long enough, our star (Sol) will die. If we are still only on earth, the human race will become extinct. I also just love exploring outside earth. I'd love to walk and explore other planets, especially a temperate Earth-like planet. I may have been born too soon for that to happen though. Answered by croc10 - Wed Mar 31 23:00:46 2010 What do you think is next for space exploration? Q. what's next for space exploration, I mean in a few years we'll be able to go on a trip to see outer space as some sort of amusment ride (eventhough it takes thousands of dollars for one to go on that ride.) I've been wondering, if we'll sometime in the near future, be doing things like you see in movies, you know having space colonies, or even on other planets. Do you think we'll be able to do such things in our lifetime? Asked by Animal Seeking Kindness - Tue Apr 7 22:35:18 2009 - - 21 Answers - 0 Comments A. I hope contact with aliens. Answered by Kieth O - Tue Apr 7 22:38:54 2009 What will be impact on mankind if we stop space exploration, fundamental physics etc. ?
Q. What will be impact on mankind if we stop space exploration, fundamental physics research (such as particle accelerator), palientology and other "fundamental" sciences ? Will it be worth rerouting those efforts to more application oriented sciences ? Asked by Rox Tarr - Thu May 20 01:12:28 2010 - - 4 Answers - 0 Comments A. If for any reason science is allow to stagnate then the religious extremists will rise and claim power over people just as the Dark Ages in Europe allow it. Even those religions with tolerance towards science progression would in the end, be shouted over and run under. application oriented sciences are needed, but they never really expand the quest to answer the unknown questions in life. They solve the known problems facing existing issues, nothing new. Hence little fear for the extremists.
