Countries all over the world continue the push to explore the final frontier: space.  In the post-Cold War era, India, China and Japan have entered the race. Why go to space? Are there not enough expensive problems on Earth? National pride and security seem to be the obvious reasons, and the lure of untapped mineral resources.

In an article on NPR’s website, Roger Launius, the senior curator in Space History at the Smithsonian's National Air and Space Museum in Washington, D.C. says, "The moon was just another place for the Cold War to play out... We really went to the moon because of the geo-political rivalry between the United States and the Soviet Union -- a competition on a broad front between two superpowers over control of the world."

Now that the Cold War has ended, the need to travel and explore space has grown more complex. The space race is no longer confined to the Moon; it includes establishing space stations, satellites for telecommunications and exploring planets, asteroids and meteors as well. Increasingly, the role of exploring space is driven by a need to augment knowledge about the physical universe in order to support the Earth. India, a developing country that has shown significant advancement in space technology, has been launching satellites that have been playing a supporting role in agriculture, water resources, urban development, mineral prospecting, environment, forestry, drought and flood forecasting, ocean resources and disaster management, according to an article on CNN’s website. India's space program founder, Vikram Sarbhai, said 60 years ago, "We are convinced that if we are to play a meaningful role nationally, and in the community of nations, we must be second to none in the application of advanced technologies to the real problems of man and society."

On the economical side of things, there are many mineral rich regions on the Moon and possibly other planets that could supplement the Earth's energy needs, therefore leading to a large economic boost for countries that hold rights to these resources. An article on Wikipedia says, "The Moon is thought to be rich in Helium-3, which could one day be used in nuclear fusion power plants to fuel future energy demands in Asia, which harbors over 60 percent of the world's population and is among its fastest-growing economies." As a result, China has been focused on sending its taikonauts to the Moon. Another article on NPR's website reported Ouyang Ziyuan, the lead scientist with China's Lunar Exploration Program, saying that the aim of China's space program is clear: to advance the country's economic and scientific development. Ouyang says, "We could meet the whole world's energy needs with a hundred tons of helium-3 a year. That means we could supply the Earth with enough energy for 10,000 years."  This is a significant finding, in view of the world's current energy crisis, such as the dwindling oil supplies and increasing climate overload.

Considering the reasons above, the quest for newer resources of energy outside our planet might be a justifiable expense. The International Space Station is a good example of cooperation between nations. Here, space travelers from many different countries work together in cooperation, while governments on Earth continue their rivalries and wars. As Carl Sagan, an American astronomer and popular science writer said, "A new consciousness is developing which sees the earth as a single organism and recognizes that an organism at war with itself is doomed. We are one planet. One of the great revelations of the age of space exploration is the image of the earth finite and lonely, somehow vulnerable, bearing the entire human species through the oceans of space and time."
