{{Main|Spaceflight}}
Essentially an extreme form of ballistic flight, spaceflight is the use of [[space technology]] to achieve the flight of [[spacecraft]] into and through [[outer space]]. Examples include [[ballistic missile]]s, [[orbital spaceflight]], etc.

Spaceflight is used in [[space exploration]], and also in commercial activities like [[space tourism]] and [[telecommunications satellite|satellite telecommunications]]. Additional non-commercial uses of spaceflight include [[Space observatory|space observatories]], [[reconnaissance satellite]]s and other [[Earth observation satellite]]s.

A spaceflight typically begins with a [[rocket launch]], which provides the initial thrust to overcome the force of [[gravity]] and propels the spacecraft from the surface of the Earth.<ref>{{Cite book| url=https://books.google.com/books?id=kjVGAAAAYAAJ&q=A+spaceflight+typically+begins+with+a+rocket+launch,+which+provides+the+initial+thrust+to+overcome+the+force+of+gravity | title=Astronautics: A Historical Perspective of Mankind's Efforts to Conquer the Cosmos | last=Spitzmiller | first=Ted | date=2007 | page=467 | publisher=Apogee Books | isbn=9781894959667 | language=en}}</ref> Once in space, the motion of a spacecraft—both when unpropelled and when under propulsion—is covered by the area of study called [[astrodynamics]]. Some spacecraft remain in space indefinitely, some disintegrate during [[atmospheric reentry]], and others reach a planetary or lunar surface for landing or impact.
