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, 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, 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 What will our space exploration look like in the next hundred or so years? Q. Last century saw the birth of space exploration. So what will this century offer to us? Possibly colonization? Asked by Rob - Fri Jan 5 13:04:30 2007 - - 5 Answers - 0 Comments A. For a long time before cars were invented people spent a great deal of time trying to go faster by breeding better horses. While mankind has found a way to get off our planet right now using our current methods exploring space requires quite a lot of effort and expenses. Hopefully we will be able to invent new methods of space flight, life support and what else is needed to start colonizing space. We already have most of what is needed it is just scattered around in different places. No one is really organizing and pushing for space colonization (yet!) But by the end of the century... I will be disappointed if man is not living outside of earth by then. Answered by dracaena - Fri Jan 5 13:42:48 2007 Is Robotic Space Exploration a good subject to write an expository essay on? Q.
