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.

How can space exploration help us prepare for potential threats?
Q. If we make further advancements in space exploration, will it help us prepare for threats? how? what kind of threats can there be?
Asked by P Boy - Thu Sep 3 00:26:54 2009 - - 2 Answers - 0 Comments

A. Yes. And depends on what 'threats' your talking about. A lot of stuff was made for the space program that we us everyday(Teflon, GPS, etc). And then there are Space Threats...rouge comets, rouge asteroids, rouge black holes and such can hit the Earth. And the sun is a threat, it will burn up the Earth one day.

should the government spend more money on space exploration or problems here?
Q. I both agree and disagree to spend more money on space exploration. And you? If not agreeing, What reasons?

A. We have a world of hurt, going on down here on Terra firma. I think that space thing could save a lot of people. Putting spy- satellites is one thing. Let us get real with our planet.

There are an estimate of 50,000 household items benefited by space exploration. Can you name a few?
Q. I'm just curious to see how many people are aware of how space exploration inpacts our lives. Some people think it's a waste of money, but lets take away some of these items and see how they feel. Most couldn't live without what they have endured today.

A. Because of space age technology ...many conveniences ... from CD players and VCR's to microwave ovens ... unheard of two or three decades ago ... have become common household items which we would now hate to be without.
