means A vehicle built to carry people or cargo through outer space.

from A straightforward 20th-century compound of 'space' and 'ship' — modeled directly on older terms like 'airship.' Once rocketry made the idea plausible rather than purely fantastical, science fiction writers in the early-to-mid 1900s popularized the word well before engineers had hardware to put under it; the vessel metaphor (a ship sailing a vast, mostly empty medium) just made too much sense to resist.
