I'm confused about the difference, if any, between the meaning/usage of spaceship and spacecraft.
Different dictionaries seem to disagree on it:
https://www.dictionary.com/browse/spaceship: defines spaceship as a synonym of spacecraft.
Vehicle used for travel in space: a manned/unmanned spacecraft (= with/without people inside)
(especially in stories) a vehicle used for travel in space
- spaceship: a spacecraft, especially one controlled by a crew.
- spacecraft: a vehicle used for traveling in space.
In other words, the first dictionary says there are no differences, the second dictionary says spaceship is mostly used in stories, and the third dictionary says that it depends on whether the vehicle is controlled by a crew.
Related: Is there a difference between a spaceship and a starship? (the difference is more clear in that case).
