Human Urine Make Concrete on the Moon for building a Moon base: ESA

Spread the love

THE European Space Agency said Friday that human urine ought to one day turn out to be a beneficial aspect in making concrete to build at the moon. The agency stated researchers in a recent observe it sponsored observed that urea, the principle natural compound in urine, would make the aggregate for a “lunar concrete” greater malleable earlier than it hardens into its sturdy final form.

The main component in “lunar concrete” could be a powdery soil determined on the Moon’s surface referred to as lunar regolith. ESA stated urea, that may smash hydrogen bonds and decrease the viscosity of fluid mixtures, might limit the amount of water necessary within the recipe.

A close collaboration between ESA researchers within the Netherlands and universities in Norway, Spain and Italy below the Ariadna initiative “allowed us to look at such an exploratory, fairly risky idea that may bring treasured effects not best for space exploration, however additionally for generation packages on Earth,” explains Shima Pilehvar, co-author of the look at and associate professor at Østfold University College, in Norway.

“Industry could benefit from subtle recipes for fire and warmth resistant inorganic polymers suitable for additive manufacturing,” she adds.


One of the hot subjects the team desires to address subsequent is how basalt fibres from the Moon should beef up the concrete and how the fabric may want to be pleasant used to guard a lunar colony. Researchers desire that this new urea-based totally mortar should help protect future astronauts from harmful degrees of ionising radiation.

“Urea is reasonably-priced and easily available, however additionally allows making robust construction material for a Moon base,” Marlies said. “The desire is that astronaut urine ought to be basically used as it’s miles on a future lunar base, with minor modifications to the water content. This is very practical, and avoids the want to similarly complicate the state-of-the-art water recycling systems in area.”

Earlier, NASA stated that astronauts ought to grow their houses on the Moon and Mars out of fungi in preference to constructing them. The space agency is exploring the possibility for it to grow to be a extra sustainable manner of residing on Earth as well.


“Thanks to future lunar inhabitants, the 1.5 liters (3.2 pints) of liquid waste a person generates every day could come to be a promising spinoff for space exploration,” it stated in a statement.

On Earth, urea is used as an industrial fertilizer and a raw material by using chemical and scientific companies.

“The desire is that astronaut urine could be basically used as it’s far on a future lunar base, with minor modifications to the water content,” observe co-author Marlies Arnhof said inside the ESA statement. “This is very practical, and avoids the want to similarly complicate the sophisticated water recycling systems in space.”
