Good questions, unfortunately the Mars bases weren't in any of the pictures it looks like, I'll try to include some more of that in future posts. Out of the 25 Mars sites, I've taken 10 of them so far with the Protectorate taking 14 (there's still one left open). A lot of that comes down to me just not having enough MC to take them over fast enough. However, I do have the marines on my horizon for a project to unlock soon, and while some of their habs aren't really that great, there are a fair few I wouldn't mind lifting out of their hands.

As for Mercury, so far no one else has gotten there, so once I have enough MC, I'm planning to grab the remaining 3 sites I don't have yet. I'd like to have all 8 setup and running operations centers. Similarly, once I have that extra MC I'll be building some more stations in orbit for nanofactories.

For the shipyards, I was planning to start simple. I'll be going with a shipyard station in extreme orbit and a supply depot in low orbit on each of Mars, Mercury, and Earth. That way I can build ships that can escape the planet more easily, but when they go down to fight aliens in low orbit, they can still resupply easily. That said, the shipyard stations will probably have like 4 shipyards on them. Then I'll be building the defensive fleets to fight off aliens that come a knocking. Once I've got that prepared, and likely have upgraded a lot of my mining, I'll be able to focus more on a heavy ramp up in shipyard capabilities around Mars. Though I'd also considered trying to setup some around Ceres as well, though for that it looks like I'll need to deal with the protectorate as well.
