means Travel beyond Earth's atmosphere in a vehicle, typically into orbit or further, using rocket propulsion to overcome gravity.

from A straightforward 20th-century compound of 'space' (from Latin spatium, an extent or expanse) and 'flight' (an old Germanic word for the act of flying). The term took off — so to speak — alongside the technology itself in the mid-1900s, as rocketry moved from fiction to fact and needed a plain name for the new kind of journey it made possible.
