New worlds? What are you talking about? You took an extreme leap in logic from the low orbit of Earth to other planets. There is NO transportation to any new worlds by Space X or any other organization and there won't be in our lifetime and it may even be impossible. The physics of sending even an unmanned craft to another solar system are overwhelming never mind a habitable world. I love the romance of space-travel too but this is trying to be a serious article isn't it? I hate to be a downer but you need to do the math on how big space is and how interstellar space travel works. The most likely cosmonauts are robots and not for a very long time.
