Okay, Star Trek fans, here’s one for ya. I don’t know if this will ever make sense, but it’s pretty to look at.
Star Trek and science do not compute.
That reminds me of the scene from Galaxy Quest when they’re taking the ship out for the first time.
That’s a great scene from a great movie.
I figure the moon, with its shallow-to-none gravity well, will make the best dry dock for spacecraft some day.
I think out in space is best, no gravity well makes moving stuff much easier and if you’re orbiting something, if you drop a tool it’s going to go along with you for a while. If you drop a person they’re going to do the same.
But that one is enclosed for no reason, if it’s floating, why enclose it? If you need to get around it, some scaffolding would be easy to erect after you’re docked, sliding it into a port is contra-indicated.
Have you seen Galaxy Quest? It’s a very darn funny movie.
They have a scene where the ship leaves an enclosed drydock that is actively painful to watch because you’re laughing so hard. It makes me laugh just thinking about it and I’ve seen the movie probably 10 times.
I also wouldn’t have it in orbit around Earth or the Moon.
If we’re in space enough to need a drydock out there, then we’re probably going to have significant traffic between Earth and the various populated planets, moons and asteroids.
Orbit the Sun somewhere convenient, depending on what the ships do, it’s a lot easier and there’s no worry about traffic a planet might have.
If you need to anchor it to a gravity well, maybe a gas giant or a moon of a gas giant.
Alternatively, do it on Mars’ moons, they’re small enough they don’t really have a gravity well but they’re solid and you can anchor stuff to them.
Unless we’re at war with bug-eyed monsters from Alpha Centauri, then all bets are off.
I saw the movie once. It was funny, but I don’t think I could watch it ten times.
