I think it's somewhere in the hundreds for sure, but not close to the 855-1000+ of the big explorers.
Well, if the ship has as many Ensigns as we see, plus an appropriate ratio of noncoms at even lower decks somewhere, we might be talking about a five-digit complement...
- Were the Cerritos and Merced towing the big slug at sublight? There seemed to have been no indication of warp speed hauling here. Were they already really close to that starbase and the first contact ship had already warped off to better adventures, perhaps dropping its charge at the edge of the system for the little ships to take her in?
Might be the very reason they found this dead colonizer is it loitered close to a system with a Starfleet presence. A fairly minor course correction would then be performed to divert it to this random Starfleet asset. (And a possibly larger correction performed to slow her down - surely she'd be barreling ahead at an ungodly speed relative to most star systems, if limited to sublight and having to do the acceleration-deceleration thing and having missed the latter half of it somehow and so forth?)
- And, you know, NOW what? The Cerritos is seen leaving the starbase with[out] their former charge. I guess they're okay leaving Durango alone to face the court martial for the loss of his ship?
Sounds like par for this particular course.
And they didn't really say what they were goign to do with the generational ship in the first place. Will they wake someone up?
Freeman's rather categorical use of "mummified" to describe the passengers suggests they all died long ago, in those "disabled" cryochambers of theirs.
Figure out where the ship was bound in the first place and send it on its way?
With the passengers dead, probably not. It would be a bit cruel, even if (as you suggest) the ship didn't end up terraforming something that really shouldn't be terraformed when there are no live operators to give it moral guidance.
