Is space exploration really desirable at a time when so much needs doing on Earth? It is an often-asked and serious question that requires a serious answer. One could present many arguments, from jobs and education to technology development and national security, for undertaking a robust space program.
In an ideal world only one argument is necessary, though in the real world some would argue it is not sufficient.
That argument is exploration, and that we should undertake it for the most basic of reasons -- our self-preservation as a creative, as opposed to a stagnating, society. Three Ages of Exploration The concepts of "discovery" and "exploration" are frequently found throughout space literature, most recently in the new Vision for Space Explorationbilled as "a renewed spirit of discovery," enunciated by President Bush in January, America enters the Third Age of Exploration.

The United States both affected and was affected by the Second and Third Ages of Exploration, but the important point is that each of those ages of exploration was the product of specific decisions of certain cultures: As historian Stephen J.
Pyne has argued, "Exploration is a specific invention of specific civilizations conducted at specific historical times. Not all cultures have explored or even traveled widely.
Some have been content to exist in xenophobic isolation. The case most often cited for a societal decision not to explore -- with generally recognized bad effects -- is Ming China in the 15th century. Is it hype, or is it history?
Some day historians will be writing about whether or not WE chose wisely, not only to make a proposal to explore, but also to fund it.
The historical facts are quite clear. While Columbus had 17 ships and men on the largest of his four expeditions, the Chinese Admiral Zheng He had ships and 27, crewmen on the first of his six expeditions. Following a maritime tradition stretching back to the 11th century, fromthese ships plied the seas of Southeast Asia, sailed to India, the Persian Gulf, the Red Sea and down the East Coast of Africa.
And yes, these are the voyages that Gavin Menzies addressed in his book The Year China Discovered America, although in my view that claim is not supported by good evidence. But what is important is this. As Boorstin noted "When Europeans were sailing out with enthusiasm and high hopes, land-bound China was sealing her borders.
Within her physical and intellectual Great Wall, she avoided encounter with the unexpected Fully equipped with the technology, the intelligence, and the national resources to become discoverers, the Chinese doomed themselves to be discovered.
By the s, the McNeils wrote, even the skills needed to build great ships were lost. Boorstin called the withdrawal of the Chinese into their own borders, symbolized by the Great Wall of China that took its current form at that time, "catastrophicWhile I disagree with the concept, there are some good arguments against space exploration that do need to be answered if we are to continue with space exploration.
There may be more, but these eight should be on any list of significant arguments. Sep 08, · The collective space vision of all the world’s countries at the moment seems to be Mars, Mars, Mars.
The U.S. has two operational rovers on the planet; a . spends the time and money to develop these products for use in space, but usually there are many civilian applications for the same products. Production of these product leads to redevelopment, sales and distribution - all of which leads to more jobs; somebody has to build, sell, and repair.
