It's in the description, world/server name is: serenity-five
Please be aware it's a visitors only world and the initial world spawn puts you at the tp hub in the middle of the spaceport (don't use the touchstones unless you want to see my older medieval area, which is quite a distance from the spaceport)
Also you'll need to give it a little time to load-in around you, there's a lot of lighting and small details going on in a relatively small number of claims with large potions of the spaceport being underground, if you fly above it you'll only see 20% of it :)

whats the spaceport server?

Oops! just noticed I've got the navigation lights the wrong way round, I'll get in trouble with the spaceport authorities!

and if you think this one is bad, you should see my Interstellar Cargo Freighter (it could be described as looking like 'a sex-toy going on vacation')

I'll make sure it comes with a Bumper-sticker that reads: 'Not to be used as an adult pleasuring device' so there's no future confusion ;)

*cough* ....merely an unfortunate side-effect of streamlined aerodynamic contour design and twin-drive vectoring thrusters

-recites, in my mind, all of the adult puns from Austin powers related to the rocket, then counts to 10 and takes a deep breath and walks away-
