You don’t want to transport large masses of equipment material to remote locations. You want to work with the soil that is there. So adding an additive to the soil, making a building component and then assembling it over a prearranged form — that same principle is achieving the habitations on the Moon and Mars. You’re moving the minimum amount of mass, of weight — of stuff out there — to a faraway destination. So payload is critical. It has to be as light as possible. So you’re using the material on the Moon and on Mars. It’s called regolith. It’s essentially the moondust. And the closest that we have is volcanic ash, very, very similar. So we’ve demonstrated with these agencies that you can — in the case of the Moon, you can send out a robot. You can send out an inflatable building and inflate the building. The robot moves around. It scoops up earth. It mixes it with the additive to form a building material that will set and that will harden. The robot creates a structure, which is based on the patterns of bones in humans and animals — very, very strong crystalline structures with lots of voids. And that gets filled by the moondust; the whole thing hardens and it creates a very, very deep crust, which is resilient to meteorites, which are going faster than the speed of a bullet. They hit it — impact it — so it’s kind of sponge-like, in that sense, and easily reparable by the robot. Out in Mars, it’s the same principles, but they’re using a microwave process to melt the outer layer of the regolith. So it’s coming back to that thing of doing more with less, of higher performance.
