Spacecraft Technology
Space technology is technology that is used in outer space, for astronautic travel, or for other activities beyond Earth's atmosphere, such as spaceflight, space exploration, and Earth observation. Deep-space communication, in-space propulsion and a wide range of other technologies such as support infrastructure equipment and procedures are examples of space technology, as are spacecraft, satellites, space stations, and orbital launch vehicles. Working in space is so novel that it frequently necessitates the development of new tools and techniques. Many common terrestrial services rely heavily on space infrastructure, including weather forecasting remote sensing, satellite navigation systems, satellite television, and some long-distance communications systems. Two of the sciences that benefit from space technology are astronomy and earth science. New technologies are being developed.
