SPACEFLIGHTS WITH OR WITHOUT HUMANS ON BOARD.

SPACEFLIGHT IS BALLISTIC FLIGHT INTO OR THROUGH OUTER SPACE. SPACEFLIGHT CAN OCCUR WITH SPACECRAFT WITH OR WITHOUT HUMANS ON BOARD. EXAMPLES OF HUMAN SPACEFLIGHT INCLUDE THE U.S. APOLLO MOON LANDING AND SPACE SHUTTLE PROGRAMS AND THE RUSSIAN SOYUZ PROGRAM, AS WELL AS THE ONGOING INTERNATIONAL SPACE STATION. EXAMPLES OF UNMANNED SPACEFLIGHT INCLUDE SPACE PROBES THAT LEAVE EARTH ORBIT, AS WELL AS SATELLITES IN ORBIT AROUND EARTH, SUCH AS COMMUNICATIONS SATELLITES. THESE OPERATE EITHER BY TELEROBOTIC CONTROL OR ARE FULLY AUTONOMOUS..BALLISTICFLIGHTOUTER SPACESPACECRAFTHUMAN SPACEFLIGHTU.S.APOLLO MOON LANDINGSPACE SHUTTLE PROGRAMSRUSSIANSOYUZ PROGRAMINTERNATIONAL SPACE STATIONSPACE PROBESEARTH ORBITSATELLITESORBITEARTHCOMMUNICATIONS SATELLITESTELEROBOTICAUTONOMOUS

SPACEFLIGHT IS USED IN SPACE EXPLORATION, AND ALSO IN COMMERCIAL ACTIVITIES LIKE SPACE TOURISM AND SATELLITE TELECOMMUNICATIONS. ADDITIONAL NON-COMMERCIAL USES OF SPACEFLIGHT INCLUDE SPACE OBSERVATORIES, RECONNAISSANCE SATELLITES AND OTHER EARTH OBSERVATION SATELLITES.SPACE EXPLORATIONSPACE TOURISMSATELLITE TELECOMMUNICATIONSSPACE OBSERVATORIESRECONNAISSANCE SATELLITESEARTH OBSERVATION SATELLITES

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. Once in space, the motion of a spacecraft both when unpropelled and when under propulsionis 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.rocketlaunchgravityastrodynamicsatmospheric reentry
