Orbital spaceflight

(重定向自Orbital flight)
Space Shuttle Discovery rockets to orbital velocity, seen here just after booster separation
 The International Space Station during its construction in Earth orbit in 2001. It must be periodically re-boosted to maintain its orbit

An orbital spaceflight (or orbital flight) is a spaceflight in which a spacecraft is placed on a trajectory where it could remain in space for at least one orbit. To do this around the Earth, it must be on a free trajectory which has an altitude at perigee (altitude at closest approach) above 100 kilometers (62 mi) (this is, by at least one convention, the boundary of space). To remain in orbit at this altitude requires an orbital speed of ~7.8 km/s. Orbital speed is slower for higher orbits, but attaining them requires higher delta-v.
