In ST:TOS, the Enterprise would often be "three weeks out" from the starbase of the week. It had a crew of about 1,000.
The majority of your comment is insightful and accurate in so far as it maps to reality. I just had to nitpick on the one fictional element I know about. The crew complement of the original series Enterprise was around 400. In fact, in the episode "A Piece of the Action", Kirk explicitly says, "There are over 400 guys up there."
And if you want to get obscure, there was The 4400. Now there was good writing!
Test your suspension of disbelief: Summer Glau was Jeffrey Combs' girlfriend...
And what is a "maroon"?
The goal of science is to build better mousetraps. The goal of nature is to build better mice.
