Space technology is technology for use in outer space, in travel (astronautics) or other activities beyond Earth's atmosphere, for purposes such as spaceflight, space exploration, and Earth observation. Space technology includes space vehicles such as spacecraft, satellites, space stations and orbital launch vehicles; ; ; and a wide variety of . The space environment is a sufficiently novel environment that attempting to work in it often requires new tools and techniques. Many common everyday services for terrestrial use such as weather forecasting, remote sensing, satellite navigation systems, satellite television, and some long-distance communications systems critically rely on space infrastructure. Of the sciences, astronomy and Earth science benefit from space technology. New technologies originating with or accelerated by space-related endeavors are often subsequently exploited in other economic activities. Astronautics and The first country on Earth to put any technology into space was Soviet Union, formally known as the "Union of Soviet Socialist Republics" (USSR). The USSR sent the Sputnik 1 satellite on October 4, 1957. It weighed about , and is believed to have orbited around the globe. Analysis of the radio signals was used to gather information about the electron density of the ionosphere, while temperature and pressure data was encoded in the duration of radio beeps. The first successful human spaceflight was Vostok 1, carrying 27-year-old Soviet cosmonaut Yuri Gagarin in April 1961. The entire mission was controlled by either automatic systems or by ground control. This was because medical staff and spacecraft engineers were unsure how a human might react to weightlessness, and therefore it was decided to lock the pilot's manual controls. The first probe to impact the surface of the Moon was the Soviet probe Luna 2, which made a hard landing on September 14, 1959. The far side of the Moon was first photographed on October 7, 1959, by the Soviet probe Luna 3.

Space Age
The Space Age is a period encompassing the activities related to the Space Race, space exploration, space technology, and the cultural developments influenced by these events, beginning with the launch of Sputnik 1 on October 4, 1957, and continuing to the present. This period is characterized by changes in emphasis on particular areas of space exploration and applications. Initially, the United States and the Soviet Union invested unprecedented amounts of resources in breaking records and being first to meet milestones in crewed and uncrewed exploration.
Private spaceflight
Private spaceflight refers to spaceflight developments that are not conducted by a government agency, such as NASA or ESA. During the early decades of the Space Age, the government space agencies of the Soviet Union and United States pioneered space technology in collaboration with affiliated design bureaus in the USSR and private companies in the US. They entirely funded both the development of new spaceflight technologies and the operational costs of spaceflight.
Spaceflight
Spaceflight (or space flight) is an application of astronautics to fly objects, usually spacecraft into or through outer space, either with or without humans on board. Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth, but also includes space probes for flights beyond Earth orbit. Such spaceflight operate either by telerobotic or autonomous control.
