The word astronomical aptly describes current price estimates for a manned jaunt to Mars: $40,000 per pound. “That’s an expensive can of Coke” for astronauts making the trip, says Brian Sauser of NASA’s New Jersey Specialized Center of Research and Training (NSCORT). So NSCORT’s mission is not to figure out how to ship food, air, and energy to Mars, but to create and re-create it up there.
