There is a easy motive that forthcoming NASA Artemis missions are slated to land across the moon’s south pole: the world is believed to harbor numerous water ice.
Not solely can people theoretically drink that moon water, they’ll additionally cut up off its oxygen atoms to create breathable air. However first, astronauts will want a strategy to flip the ice into liquid water.
Discovering a possible means to try this is the aim of the Aqualunar Problem. A collaboration between the U.Ok. and Canadian House Businesses, the Problem duties groups from each international locations to suggest a means for future guests to the moon to supply liquid water on the lunar floor. Now, the Problem’s organizers have introduced the ten U.Ok. finalists.
Their activity is just not a easy one. It takes loads of work to show lunar water ice into potable water, not to mention separate it into hydrogen and oxygen. Not solely is the water frozen rock-hard, it is possible riddled with lunar regolith that can flip right into a gritty, unpalatable slurry when moist. Moon dwellers should not solely soften the ice, they need to additionally purify it.

Every crew’s proposed tech should have the ability to survive the cruel chilly and razor-sharp mud particles of the lunar south pole, whereas protecting mass as little as doable. Moreover, particularly with a activity that might make the distinction between life and demise for astronaut explorers, their chosen methodology have to be low upkeep.
“They can’t depend on parts being despatched up from Earth, and it will not be doable for astronauts to recurrently change filters and tighten nuts and bolts,” mentioned UKSA reserve astronaut Meganne Christian in a statement.
Christian can also be one of many judges tasked with evaluating the ten British finalists, every of whom envisions a special strategy.
Take Lunasonic, which might first soften the ice into water and purify it by blasting it with ultrasound waves, like a jewellery cleaner. Alternatively, the Regolith Ice Plasma Purifier for Lunar Exploration (RIPPLE) proposal would vaporize the ice, push it right into a vortex and wick out pollution like a salad spinner. Then there may be the dramatically named Ganymede’s Chalice, which might use mirrors to pay attention daylight onto a crucible crammed with ice, boiling away contaminants one after the opposite, leaving clear water on the finish.
Over the following a number of months, the groups behind these three concepts, in addition to seven others, will work on growing their expertise with the help of a £30,000 (about $38,500 US at present change charges) grant. Lastly, in March 2025, organizers will announce a U.Ok. winner and two runners-up.
On the opposite aspect of the Atlantic, the organizers of Canada’s competitors announced eight semi-finalists. They’re going to be whittled right down to 4 finalists in early 2025, with a ultimate Canadian winner introduced in early 2026.
