Sending construction materials to the moon is such a challenge that researchers came up with a new concrete formula using human settlers’ urine.

00:00Building settlements on the moon is a big step towards colonizing Mars and beyond, but
00:07we can't just pack large amounts of concrete into a spaceship.
00:10According to a European research team, it costs $10,000 to launch about a pound of any
00:16material into space.
00:17So the researchers found a way for humans to make concrete on the moon using their own
00:22urine.
00:23The concrete formula uses urea, which is the other main ingredient in urine aside from
00:27water.
00:28When mixed with regolith or lunar soil, urea helped this substance keep its shape and strength.
00:33According to CNET, this mixture was used to 3D print cylinders, which is how a moon base
00:38could be constructed.
00:39And it seemed to get even stronger after being frozen and thawed, which is exactly what could
00:43happen to it on the moon.
