I'm a bit confused about what happens when you launch a ship. I did this once with a few of my colonists, thinking they would branch off and start their own colony. They just kinda disappeared. I could go back and play with the rest of my colonists, but that was it. If you put all of your colonists on the ship and launch them all at once, do you then get to go and colonize another planet? Perhaps I'm daft, but I thought you were supposed to be able to move on and colonize other worlds if you want.
