The Great Lunar Railroad--DARPA / Northrop Grumman Project

The Defense Advanced Research Projects Agency (DARPA) tapped Northrop Grumman to develop a concept for a lunar railroad, the defense prime contractor announced this week. The contract was awarded under the LunA-10 initiative, which is exploring all sorts of out-there concepts to encourage the growth of a sustainable lunar economy in the next decade.
The company will continue advancing the railroad concept it’s been working on in secret since securing the preliminary contract in December. That theoretical railroad would transport people and cargo across the moon’s surface.
