Because there are no targets around. 
You can use a turretangle-tbm to fix it.
True, but I don't see why it should be done. It doesn't pose a problem and seems an EA feature, mantained to underline the technological differences between the EA and any other faction.
Well if it's an EA feature to look like all your turrets have raging erections, okay. But it just makes it look like the ships really need to get off.
Well, the moon in and of itself is too small to retain an atmosphere, whereas Mars does naturally retain an atmosphere but loses oxygen to space. But hey, the terraformed Moon looks cool, so go for it. You don't have to go the hard-SF route.
That's where the date plays a vital role. If all necessary technologies were available in the early days of space colonization, there was no reason why Mars would have been terraformed before the Moon. The fact that terraforming of the Moon started in the 2350s (after INFASA's main campaign) means that an important discovery made it possible (otherwise, it would have been started in the 2150s or even earlier). All technological progresses in INF will be described, so you'll have a proper explanation for that and many other things. 
No, you're missing the point. There's a fundamental difference that makes Mars terraforming possible in a hard-SF setting but rules out the Moon.
The Moon can't retain an atmosphere. It's too small.
Mars can retain an atmosphere. It's big enough.
The Moon is ridiculously, absurdly more difficult to terraform.
I have no problem with it being terraformed, because it's a fantasy, you can do whatever you want. But there's a reason that Mars would be terraformed before the Moon: it can be terraformed without fantasy tech, and the Moon can't.
