Introduction
Spaceflight is the movement of spacecraft into and through outer space, primarily using rocket technology for propulsion. Spaceflight is used in space exploration, the endeavour to reach, explore, and exploit the space outside the Earth's atmosphere, and also in commercial activities like space tourism and satellite telecommunications. It is generally based on the use of rockets to transport machines, animals, and humans to, and subsequently through, space. Additional non-commercial uses of spaceflight include space observatories, reconnaissance satellites and other earth observation satellites. Objects launched into space may follow a sub-orbital trajectory and return to Earth immediately, stay in orbit around Earth, travel in the space between the planets, or aim to leave the space dominated by the Sun completely.
