Spaceflight Space_exploration

spaceflight use of space technology achieve flight of spacecraft , through outer space.

spaceflight used in space exploration, , in commercial activities space tourism , satellite telecommunications. additional non-commercial uses of spaceflight include space observatories, reconnaissance satellites , other earth observation satellites.

a spaceflight typically begins rocket launch, provides initial thrust overcome force of gravity , propels spacecraft surface of earth. once in space, motion of spacecraft—both when unpropelled , when under propulsion—is covered area of study called astrodynamics. spacecraft remain in space indefinitely, disintegrate during atmospheric reentry, , others reach planetary or lunar surface landing or impact.
