exploration

exploration

[ek-spluh-rey-shuhn]
exploration, travel to a part of the earth that is relatively unknown to the traveler's culture, historically often motivated by a desire for colonization, conquest, or trade.

Early Exploration

Early Egyptian expeditions penetrated into Nubia and Mesopotamia; the Phoenicians and the Greeks explored the Mediterranean and the Black Sea regions earlier than 600 B.C.; and a Phoenician expedition (c.600 B.C.) is said to have sailed around Africa. After 500 B.C. the Carthaginians explored beyond the Strait of Gibraltar to trade along the coasts of Spain and Africa. A Greek navigator, Pytheas, sailed beyond Britain c.310 B.C. The conquests of Alexander the Great brought the West in closer relationship with the East, and the Roman legions extended the limits of geographical knowledge, especially in N Europe. Trade with the East was stimulated by the discovery (c.A.D. 15) of a sea captain, Hippalus, that by using monsoon winds it was possible to sail across the Indian Ocean instead of hugging the coast. Roman trade was early established with India and Sri Lanka and later (c.A.D. 100) with China.

After the dissolution of the Roman Empire, the Arabs expanded their relationships with the East. The Chinese also made many explorations in this period. One of the best-known Chinese travelers is Hsüan-tsang, who traveled (A.D. 629-646) to India and farther west. Exploration by Europeans was carried on during the Middle Ages by Norse adventurers and colonists who crossed the Atlantic to Iceland, Greenland, and North America. Their journeys, however, did not have much influence on the rest of Europe. European knowledge of Asia gained during the Crusades was extended by the journeys across Asia made by missionaries and by Marco Polo.

The European "Age of Discovery"

By about 1400 the breakup of the Mongol empire and the growth of the Ottoman Empire had blocked Europe's overland trade routes to the East. The search for new trade routes, the rise of merchant capitalism, and the desire to exploit the potential of a global economy initiated the European "age of discovery." Henry the Navigator promoted voyages along the coast of Africa that helped dispel the superstition and misinformation that had impeded previous attempts to sail through the torrid zone. The extent of the globe was revealed by Bartholomew Diaz's rounding of the Cape of Good Hope (1486-87), Vasco da Gama's voyage to India (1497-98), Christopher Columbus's first voyage to America (1492), and the circumnavigation of the globe by the expedition of Ferdinand Magellan (1519-22). In the 16th cent. Spanish explorers, notably Vasco de Balboa, Hernán Cortés, Francisco Pizarro, Cabeza de Vaca, Hernán De Soto, and Francisco de Coronado, explored large areas of the Americas. Much of the interior of North America was revealed in the 17th cent. by Samuel de Champlain, Sieur de La Salle, Louis Jolliet, Jacques Marquette, and other French explorers.

A Spanish and Portuguese monopoly of the new trade routes stimulated attempts to find other passages to the East (see Northeast Passage and Northwest Passage) and was soon challenged by English and Dutch voyages in the Pacific and Indian oceans. Most of the major islands of the Pacific and the coastline of Australia became known to Europeans through the voyages of Francis Drake, Abel Tasman, William Dampier, James Cook, Vitus Bering, George Vancouver, and others. European exploration of the interior of Australia took place in the mid-19th cent., and by the end of the century most of Africa had been explored by David Livingstone, H. M. Stanley, and Richard Burton.

European exploration and colonization frequently had disastrous results for the indigenous peoples. Diseases brought to the Americas and Australia by Europeans decimated the inhabitants, and European intervention in Africa expanded the already thriving slave trade. The aboriginal peoples often viewed the presence of explorers as an encroachment, inevitably leading to war, repression, and dislocation.

Polar Explorations

In the late 19th and early 20th cent. the Arctic was explored by Nils Nordenskjöld, Roald Amundsen, Donald MacMillan, Richard Byrd, and others. In 1909, Robert E. Peary reached the North Pole. The continent of Antarctica was explored in the first half of the 20th cent. by William Bruce, Jean Charcot, Douglas Mawson, Ernest Shackleton, and others. The South Pole was reached first by Amundsen (Dec. 14, 1911) and almost immediately thereafter (Jan. 18, 1912) by Robert Scott. The airplane provided a new method of antarctic exploration, with George Wilkins and Richard E. Byrd as the pioneers. Since World War II there have been many well-equipped expeditions, most notably those during the International Geophysical Year (1957-58), to the Antarctic.

Investigation of the universe beyond Earth's atmosphere by means of manned and unmanned spacecraft. Study of the use of rockets for spaceflight began early in the 20th century. Germany's research on rocket propulsion in the 1930s led to development of the V-2 missile. After World War II, the U.S. and the Soviet Union, with the aid of relocated German scientists, competed in the “space race,” making substantial progress in high-altitude rocket technology (see staged rocket). Both launched their first satellites (see Sputnik; Explorer) in the late 1950s (followed by other satellites and unmanned lunar probes) and their first manned space vehicles (see Vostok; Mercury) in 1961. A succession of longer and more complex manned space missions followed, most notably the U.S. Apollo program, including the first manned lunar landing in 1969, and the Soviet Soyuz and Salyut missions. Beginning in the 1960s, U.S. and Soviet scientists also launched unmanned deep-space probes for studies of the planets and other solar system objects (see Pioneer; Venera; Viking; Voyager; Galileo), and Earth-orbiting astronomical observatories (see, for example, Hubble Space Telescope), which permitted observation of cosmic objects from above the filtering and distorting effects of Earth's atmosphere. In the 1970s and '80s the Soviet Union concentrated on the development of space stations for scientific research and military reconnaissance (see Salyut; Mir). After the dissolution of the Soviet Union in 1991, Russia continued its space program, but on a reduced basis owing to economic constraints. In 1973 the U.S. launched its own space station (see Skylab), and since the mid 1970s it has devoted much of its manned space efforts to the space shuttle program and, more recently, to developing the International Space Station in collaboration with Russia and other countries.

Exploration is the act of searching or traveling for the purpose of discovery, e.g. of unknown people, including space (space exploration), for oil, gas, coal, ores, caves, water (Mineral exploration or prospecting), or information.

Although exploration has existed as long as human beings, its peak is seen as being during the Age of Discovery when European navigators traveled around the world discovering new lands and cultures.

Other uses

The term may also be used metaphorically, for example persons may speak of exploring the internet, sexuality, etc.

In scientific research, exploration is one of three purposes of research (the other two being description and explanation). Exploration is the attempt to develop an initial, rough understanding of some phenomenon.
