Space technology
Summary
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.
