I don’t intend Generation Mars to be a dystopian saga. That doesn’t suit the target age range and, even if it did, there are too many of those around already. So I don’t see armed interplanetary conflict as part of the series. However, it is interesting to think about the physics of such conflict in space and just how wrong most sci-fi movies get it. And there is a lot to be learned from such thought experiments. The discussion of heat transfer in this video is a good example.
