Space exploration is the physical exploration of outer- Earth objects and generally anything that involves the technologies, science, and politics regarding space endeavors. One of the most famous and important aspects of space exploration was the landing of the first man on the moon in the space race between the United States and the Soviet Union.

1 From fiction to fact

The idea of sending an object to space was conceived in the minds of many science fiction authors hundreds of years before it was actually feasible. Some of these works even included various descriptions of exactly how that would be done. During the 20th century, with the development of adequate propulsion technologies, stronger and lighter materials and other technological and scientific breakthroughs, the idea of outer-earth missions was no longer a dream, but a viable practice.

The National Air and Space Museum (NASM) on the National Mall in Washington, D.C. displays a moon rock sample which the public can see and touch, a Gemini space capsule and Soviet rockets. The NASM annex at Dulles International Airport in Northern Virginia displays an unparalleled array of aerospace technology in one place: Space Shuttle EnterpriseThe Shuttle Orbiter Enterprise (NASA Designation: OV-101) was the first Space Shuttle built for NASA. It was initially constructed without engines or a functional heat shield and was therefore not capable of space operations without a refit. It was intend, a Concorde and scores of aircraft.

It is one of the most widely distributed photographic images in existence. Original caption: View of, a 19721972 is a leap year starting on Saturday (click link for calendar).

2 Orbitting and reaching space

From a spaceflight perspective, the definition of space usually used is that space begins 100 km (62 miles) above Earth's surface. The United States sometimes uses a 50 mile definition. (See boundary to space.)

Achieving orbit is a prerequisite for going anywhere else, such as to the MoonFor other moons in the solar system see natural satellite. For other uses see Moon (disambiguation). The Moon is the only natural satellite of Earth. It has no formal name other than "The Moon" although it is occasionally called Luna ( Latin for moon to d or MarsMars is the fourth planet from the Sun in the solar system, named after the Roman god of war (the counterpart of the Greek Ares), on account of its blood red color as viewed in the night sky. Mars has two small moons, Phobos and Deimos, both small and odd. The first successful orbital launch was of the Soviet unmanned Sputnik I mission on October 4, 1957. Laika became the first animal in orbit on November 3, 1957. The first orbital flight made by a human being was Vostok 1, carrying Yuri Gagarin on April 12 1961.

One can distinguish the sub-orbital spaceflight and the orbital spaceflight (cf. Difference between sub-orbital and orbital spaceflights). As for sub-orbital flights, on October 3, 1942 an A4 rocket, a prototype for the German V2 rocket bomb, became the first successful launch of an object into space. The first organisms launched into space were fruit flies and corn seeds aboard a U.S.-launched V2 rocket in July, 1946. Another milestone was achieved on May 17, 2004 when Civilian Space eXploration Team launched the GoFast Rocket on a suborbital flight, the first amateur space flight. On June 21, 2004, SpaceShipOne became the first private human spacecraft.
