The water economy of cislunar space

Mining the Moon changes everything. In an article in Air and Space, several prominent scientists we’ve been following discuss how in situ resource utilization (ISRU) can close the business case for companies that will build the infrastructure for a cislunar economy.

George Sowers of Colorado School of Mines and lead researcher on a recent study of ice mining in the solar system believes that water is “the oil of space” which can be used for all sorts of propulsion needs as well as supporting life. He believes that “…the economy of space will run off of water.”

Kevin Cannon, who has developed a treasure map for where the ice deposits are located at lunar poles based on satellite data to support ISRU, believes that we need to follow up with actual prospecting hardware to confirm how much water is actually present.

Joel Sercel, CEO of Trans Astronautica Corporation and recent recipient of a Phase II NIAC grant for a Lunar Polar Mining Outpost, has proposed calling a base located at the Moon’s north pole “New Mesopotamia” likening it to the Fertile Crescent in the Middle East on Earth.

Most of the experts agree that fuel depots on the moon are needed for a sustainable economy in cislunar space before we can push off to Mars and beyond.
