That's no space station, it's a moon !

Yup. I use that trick all the time. I always try and select a planet with one or more moons around it for my main military base in a given system, and load the moons up with defense platforms.

This works best if you use a race that breathes "none", so you can toss a Space Yard on each moon & pump out 1000's of missile defence sats, as well as having piles of Massive Mount WMGs on the moons.
And since you don't have to convert the moon's atmosphere, you can do this from turn 1

COOL Idea! thanks....Look out AI

A very nice thing about moons is that if you colonize one in a system, the planet doesn't show up as colonized. Basically, you can see what is in the system without anyone knowing you are there. Well, they won't know you are there unless they click on planet. I had a heckuva time wiping out an enemy because he had colonized a moon. It took forever to finally find him.

I use moon exlusively for Intel bases. I colonize a moon, and then stick an Atomsphere Converter on it.

Once its converted, I take out the AC, and build nothing but intel related operations.

Or, I destroy the moon, and rebuild it. In many cases, it rebuilds with an atomsphere.
