You cannot terraform barren planets
And that is a problem. IMO.
[Scientific mode ON]
Each time we are talking about terraforming we should consider four huge objectives it consist of:
-Temperature.
-Atmosphere.
-Hydrosphere.
-Lithosphere.
Probably, the most understandable part is a temperature. Obviously, you should cool the hot planets and warm up the cold ones. Nowadays science is unable to make this, but Sci-Fi have a many ways to do so. In a Starsector vanilla it is made by a solar shades and a stellar mirrors orbiting some core worlds planets. This method is already implemented in a mod.
Other objective already possible by this mod is a Hydrosphere. Capturing an icy asteroids and guiding them to any desirable planet is possible even with a modern technologies, all the problem is the amount of resources you are ready to spend. No magic here.
Barren planets has no atmosphere at all. That might be looks bad, but it is not. You see, the Earth hydrosphere mass is 1.46*1021 kg and the atmosphere mass is 5.2*1018 kg. That means, adding an air to Earth-sized planets is approximately 10000 times easier, than adding a water, which is already possible by this mod. Each solar system has a lot of frozen pieces of ice in its Kuiper belts, many of them are ammoniac - good source of a nitrogen, 78% of the atmosphere. Oxygen can be found both in an asteroids and a planetary cores of a barren planets in a bound state. So, there are no problem with a source. However, adding an atmosphere is only half of a problem, the other one - is to hold it. Lack of a gravity and/or magnetic field will result solar wind will blow all the air you add. Changing a gravity or a magnetic field is a tricky task. Fortunately, we do not need this, as vanilla already has an answer, called a "planetary shield". If that thing is able to complicate penetration from the outside, it should be able to keep gases inside, and stop the solar winds. Consider it as a planetary-scale dome.
Lithosphere is the hardest challenge. You can't replace even a small upper layer if it is inappropriate. That is such a HUGE effort, even MUD magic can't deal with. However, it is not necessarily you need it at all. See, not all of the barren worlds has a poisonous inappropriate core. Earth's Moon can be considered as a typical barren, or a barren-bombarded world. Soil samples, delivered by the Apollo missions shows, that it is fit to farming if water and organics is added. Results, similar to Moon was acquired from a Mars probes. That is not surprising, as all of the planets was made from the same accretion disk, and contain exactly same elements in a different proportion. Many of a Starsector systems have a habitable worlds, that means barren planets have a serious chance to consist of a proper substances to support life.
If short - barren planets should be able to terraform. If not all, but some kinds. If not to terran type, but something else.
[Scientific mode OFF]
Frankly said, I don't need it. I'm OK with my barren planets remain barren. However, I just have to say all of this. For great justice!©
