So, this question goes to the developers. Will their be some space travel eventually? I would love to see some extra terrestrial exploration and scientific discoveries. It could be like Kerbal Space Program but more expansive. This is of course purely hypothetical, and I realize that their are still many things to add in and iron out before something like this could be even a possibility.
