In general, NASA uses the terms "spaceship", "spacecraft" and "space vehicle" more-or-less interchangably for technology that transports astronauts. They seem slightly less likely to use the word "spaceship", perhaps due to its Science Fiction roots.
They also seem more likely to use the word "spacecraft" when referring to unmanned flights.
The term "spaceship" seems to turn up more in NASA material directed at children and students, and less in their more technical publications. NASA choice of terminology is noticeably situational; in-house terminology such as "extra-vehicular activity" or "EVA" gets translated to "spacewalk" for their non-technical audience.
There don't seem to be any rules regarding any of this. My answer is based on a lot of reading as a science educator, but I do not claim to have conducted any detailed scientific study of the number of times NASA uses each term.
Comment: This answer is perfect in its detail, and in its simplicity. It is understandable to the student and to the advanced scientist. It should not be included in "flagged questions", indicating that there is a problem. If a person cannot understand this answer, they should not be supervising this category.

Because they are not going fast enough
Most spaceships are unpainted.
