coal is great but a bit premitive. I was hoping you can add the Atomic Science mod or create maybe a solar generator or something the Atmoic Science would be greate inside a Space Station. Also you should make it where you can teraform the planets. the moon is habitable with 15% gravity which those stats should change over time depending on how much life, oxygen, and H2O. On the Airlocks if there isn't air in a area say 2x2 and it is sealed it should fill in the small space with air. Make it where you can right click a cow with oxygen gear so it can survive. make a rocket with multiple seats. airlocks that lay sideways so you can place them over rocket exits and other roof openings. cryo tubs (beds) that have air and electricty going to them that alow sleeping in space. also with the air system make it where the air being generated, has to be inside a inclosed space like a cube or sphere or something like that. and on the air generator make a valve that can be regulated so the player can determine the amount of air being release in the area (depeneding on the amount of oxygen it can generate).
