By some estimates, the first interstellar voyage will cost many trillions of dollars, require decades to construct and involve tens to hundreds of passengers and explorers. It will certainly cost more than the $100 billion for our first manned trip to Mars! Assuming a project of this scope can even be sold to the teeming humanity that will be left behind to pay the bills, how will the destination be selected? Will we just point the ship towards any star and commit these resources to a random journey and outcome, or will we know a LOT about where we are going before the fuel is loaded? Most of us will agree that the latter case for such an expensive “one off” mission is more likely.
So… Where will they go?
