The European Space Agency made the announcement last Friday. A compound present in urine reacts in a specific and beneficial way with moon dust. Their discovery comes as scientists plan construction of a lunar space station on the surface of the moon. By bringing fewer building materials from Earth, researchers reduce the mission’s cost. Lunar concrete would use lunar regolith, the soil covering the surface of the moon and water transported from Earth. That’s where the pee comes in; the urea in urine breaks hydrogen bonds and reduces viscosity of fluid.
