I'll expand a little on my space fleet but I was originally planning on putting the Observer (my HQ Invasion Carrier) and the entire invasion fleet in a small orbit near the pole. So you'll probably be fightning me if nobody objects.
Double post go!
The Ashtar main base there would be problematic for a polar orbit.
I suppose anybody orbiting anywhere in the planet's immediate vicinity would be problematic, due to the treaty limitations on bombardment, while ground guns have no limitations firing back. I ended up putting the Ashtar main space presence farther out in the system, that might work for people? Orbit the moon, orbit a different planet, orbit a big ol asteroid?
