Space exploration is the use of astronomy Astronomy is the scientific study of celestial objects and phenomena that originate outside the Earth's atmosphere (such as the cosmic background radiation). It is concerned with the evolution, physics, chemistry, meteorology, and motion of celestial objects, as well as the formation and development of the universe and space technology Space technology is technology that is related to entering space, maintaining and using systems during spaceflight and returning people and things from space to explore outer space Outer space is the space beyond the Earth's atmosphere. Outer space is usually defined from the point of view of the Earth and is used to distinguish it from airspace and terrestrial locations. The term can also be expanded to include the regions outside other celestial bodies in the Solar System (interplanetary space) or the regions outside the.[1] Physical exploration Exploration is the act of searching or traveling a terrain for the purpose of discovery, e.g. of unknown people, including space , for oil, gas, coal, ores, caves, water, (Mineral exploration, botanical exploration, or prospecting), or information of space is conducted both by human spaceflights Human spaceflight is spaceflight with a human crew and possibly passengers. This makes it unlike robotic space probes or remotely-controlled satellites. Human spaceflight is sometimes called manned spaceflight, a term now deprecated by major space agencies in favor of its gender-neutral alternative and by robotic spacecraft A robotic spacecraft is a spacecraft with no humans on board, that is usually under telerobotic control. A robotic spacecraft designed to make scientific research measurements is often called a space probe. Many space missions are more suited to telerobotic rather than crewed operation, due to lower cost and lower risk factors. In addition, some. While the observation of objects in space, known as astronomy Astronomy is the scientific study of celestial objects and phenomena that originate outside the Earth's atmosphere (such as the cosmic background radiation). It is concerned with the evolution, physics, chemistry, meteorology, and motion of celestial objects, as well as the formation and development of the universe, predates reliable recorded history Recorded history is human history that has been written down or recorded by the use of language. It starts in the 4th millennium BC, with the invention of writing. The period before this is known as prehistory, it was the development of large liquid-fueled rocket engines A rocket engine or simply "rocket" is a jet engine that uses only propellant mass for forming its high speed propulsive jet. Rocket engines are reaction engines and obtain thrust in accordance with Newton's third law. Since they need no external material to form their jet, rocket engines can be used for spacecraft propulsion as well as 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 Cold War was the continuing state of political conflict, military tension, and economic competition existing after World War II (1939–1945), primarily between the USSR and its satellite states, and the powers of the Western world, including the United States. Although the primary participants' military forces never officially clashed. The early era of space exploration was driven by a "Space Race The Space Race was an informal competition between the United States and the Soviet Union, as each side tried to match or better the other's accomplishments in exploring outer space. It involved the efforts to explore outer space with artificial satellites, to send man into space, and to land him on the Moon" between the Soviet Union The Union of Soviet Socialist Republics was a constitutionally socialist state that existed in Eurasia from 1922 to 1991. The name is a translation of the Russian: Союз Советских Социалистических Республик (help·info), tr. Soyuz Sovetskikh Sotsialisticheskikh Respublik, IPA [sɐˈjʊs sɐˈvʲeʦkʲɪx səʦɪ and the United States The United States of America is a federal constitutional republic comprising fifty states and a federal district. The country is situated mostly in central North America, where its forty-eight contiguous states and Washington, D.C., the capital district, lie between the Pacific and Atlantic Oceans, bordered by Canada to the north and Mexico to the; the launch of the first man-made object to orbit the Earth Earth is the third planet from the Sun, and the fifth-largest of the eight planets in the Solar System. It is also the largest, most massive, and densest of the Solar System's four terrestrial (or rocky) planets. It is sometimes referred to as the World, the Blue Planet,[note 3] or Terra.[note 4], the USSR's Sputnik 1 Sputnik 1 (Russian: "Спутник-1" Russian pronunciation: [ˈsputnʲɪk], "Satellite-1", ПС-1 ) was the first Earth-orbiting artificial satellite. It was launched into an elliptical low earth orbit by the Soviet Union on 4 October 1957, and was the first in a series of satellites collectively known as the Sputnik program, on October 4, 1957, and the first Moon The Moon is Earth's only natural satellite and the fifth largest satellite in the Solar System. The average centre-to-centre distance from the Earth to the Moon is 384,403 kilometres , about thirty times the diameter of the Earth. The common centre of mass of the system (the barycentre) is located at about 1,700 kilometres (1,100 mi)—a quarter landing by the American Apollo 11 The Apollo 11 mission landed the first humans on the Moon. Launched on July 16, 1969, the third lunar mission of NASA's Apollo Program was crewed by Commander Neil Alden Armstrong, Command Module Pilot Michael Collins, and Lunar Module Pilot Edwin Eugene 'Buzz' Aldrin, Jr. On July 20, Armstrong and Aldrin became the first humans to land on the craft on July 20, 1969 are often taken as the boundaries for this initial period. The Soviet space program The Soviet space program refers to the rocketry and space exploration programs conducted by the Soviet Union from the 1930s until its dissolution in 1991. Over its sixty-year history, this primarily classified military program was responsible for a number of notable accomplishments in space flight, including mankind's first intercontinental achieved many of the first milestones, including the first living being in orbit in 1957, the first human spaceflight Human spaceflight is spaceflight with a human crew and possibly passengers. This makes it unlike robotic space probes or remotely-controlled satellites. Human spaceflight is sometimes called manned spaceflight, a term now deprecated by major space agencies in favor of its gender-neutral alternative (Yuri Gagarin Yuri Alekseyevich Gagarin , Hero of the Soviet Union, was a Soviet cosmonaut. On 12 April 1961, he became the first human in outer space and the first to orbit the Earth. He received medals from around the world for his pioneering tour in space aboard Vostok 1 Vostok 1 was the first human spaceflight. The Vostok 3KA spacecraft was launched on April 12, 1961, taking into space Yuri Gagarin, a cosmonaut from the Soviet Union. The Vostok 1 mission was the first time anyone had journeyed into outer space and the first time anyone had entered into orbit. The Vostok 1 was launched by the Soviet space program) in 1961, the first spacewalk Extra-vehicular activity is work done by an astronaut away from the Earth, and outside of a spacecraft. The term most commonly applies to an EVA made outside a craft orbiting Earth (a spacewalk), but also applies to an EVA made on the surface of the Moon (a moonwalk). In the later lunar landing missions (Apollo 15, 16, and 17) the command module (by Aleksei Leonov Alexey Arkhipovich Leonov is a retired Soviet/Russian cosmonaut and Air Force General who, on March 18, 1965, became the first human to conduct a space walk) in 1965, the first automatic landing Luna 9 (internal name E-6 N. 13), was an unmanned space mission of the Soviet Union's Luna program. On February 3, 1966 the Luna 9 spacecraft was the first spacecraft to achieve a lunar soft landing and to transmit photographic data to Earth on another celestial body in 1966, and the launch of the first space station To date, only low earth orbital stations have been implemented, otherwise known as orbital stations. A space station is distinguished from other manned spacecraft by its lack of major propulsion or landing facilities—instead, other vehicles are used as transport to and from the station. Space stations are designed for medium-term living in orbit, (Salyut 1 Salyut 1 (Russian: Салют-1; English translation: Salute 1) was the first space station of any kind, launched on April 19, 1971) in 1971.
After the first 20 years of exploration, focus shifted from one-off flights to renewable hardware, such as the Space Shuttle program NASA's Space Shuttle, officially called Space Transportation System , is the United States government's current manned launch vehicle. The winged Space Shuttle orbiter is launched vertically, usually carrying five to seven astronauts (although eight have been carried) and up to 50,000 lb (22 700 kg) of payload into low earth orbit. When its, and from competition to cooperation as with the International Space Station The International Space Station is an internationally developed research facility currently being assembled in Low Earth Orbit. On-orbit construction of the station began in 1998 and is scheduled to be completed by 2011, with operations continuing until at least 2015. The station can be seen from the Earth with the naked eye, and, as of 2009[.
From the 1990s onwards, private interests began promoting space tourism Space tourism is the recent phenomenon of tourists paying for flights into space. As of 2009, orbital space tourism opportunities are limited and expensive, with only the Russian Space Agency providing transport. The price for a flight brokered by Space Adventures to the International Space Station aboard a Soyuz spacecraft is US$20–35 million and then private space exploration of the Moon (see GLXP The Google Lunar X Prize, sometimes referred to as simply Moon 2.0, is a space competition organized by the X Prize Foundation, and sponsored by Google. It was announced at the Wired Nextfest on 13 September 2007).

In addition, the territories under the jurisdiction of the Republic of China, commonly known as Taiwan, are also excluded initiated a successful manned spaceflight program The space program of the People's Republic of China was initiated soon after the country's founding in 1949. Eventually, this space program covers anti-ballistic missile system[citation needed], anti-satellite weaponries[citation needed], reconnaissance satellites, manned spaceflights, "space laboratories", space stations and spaceplanes,, while the European Union The European Union is an economic and political union of 27 member states, located primarily in Europe. Committed to regional integration, the EU was established by the Treaty of Maastricht on 1 November 1993 upon the foundations of the European Economic Community. With almost 500 million citizens, the EU combined generates an estimated 30% share (, Japan Japan is an island country in East Asia.

The United States has committed to return to the Moon by 2018 and later Mars.[2][3][4] 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 The Aurora programme is a human spaceflight programme of the European Space Agency established in 2001 with the primary objectives of creating, and then implementing, a European long-term plan for exploration of the Solar System using robotic spacecraft and human spaceflight. A secondary objective is to search for life beyond the Earth during the 21st century.[5]

A. You're in luck! There's a new book called: The Privatization of Space Exploration, published by Transaction Publishers. Full description of the book is here: From the book (available from the publisher and online book vendors like Amazon): "In the first decade of the twenty-first century, private enterprise is bubbling away, threatening to change the space landscape forever. Individuals are designing spacecraft, start-up companies are testing prototypes, and reservations are being taken for suborbital flights. With for-profit enterprises seeking to carve out a new realm, the exploration and commercialization of space, the development of space as a tourist destination will likely soon become a reality."
