UK Space Agency Funds Lunar Tech

the UK Space Agency has awarded funding to ten innovative technologies aimed at purifying water frozen in the Moon’s soil.

Through the joint UK-Canada £1.2 million Aqualunar Challenge, these UK finalists are poised to develop solutions crucial for establishing a sustainable human presence on the Moon.

Pioneering Solutions for Lunar Water Supply

The Aqualunar Challenge, part of a £1.2 million international prize funded by the UK Space Agency’s International Bilateral Fund and managed by Challenge Works, aims to revolutionise water purification technology for lunar missions.

This collaboration with the Canadian Space Agency (CSA) and Impact Canada will see UK-led teams awarded £30,000 each to advance their technologies before the final winner is announced in Spring 2025.

The Necessity for Lunar Water

Around the lunar south pole, approximately 5.6% of the soil is water frozen as ice. For a permanent crewed base on the Moon, astronauts will need a reliable supply of water for drinking, growing food, and producing oxygen and hydrogen.

Extracting, separating, and purifying lunar ice is crucial to making NASA’s Artemis campaign, supported by the UK Space Agency, a reality by the end of this decade.

Paul Bate, CEO of the UK Space Agency, emphasised,

“The ambition to build a sustainable human presence on the Moon through the NASA-led Artemis Missions will only succeed if we have ways of generating a reliable supply of clean water.”

“The Aqualunar Challenge showcases a range of innovative ideas from UK teams and individuals to tackle this challenge, while strengthening ties with our Canadian partners.”

Innovative Technologies and Their Developers

The ten finalist teams have presented a variety of solutions, each with unique approaches to purifying lunar water. Here are some of the standout technologies:

• Titania-Diamond Annular Reactor (TiDAR): Developed by Nascent Semiconductor Ltd, this compact system uses UV light and diamond electrodes to break down harmful components in lunar soil, producing safe drinking water and useful materials like rocket fuel from methanol.
• SonoChem System: Naicker Scientific Ltd employs powerful sound waves to create micro-bubbles in contaminated water, which generate free radicals to remove impurities.
• Ganymede’s Chalice: This British Interplanetary Society innovation uses a solar concentrator to boil ice components and condense pure water, utilising a curved mirror to focus the Sun’s rays.
• AquaLunarPure: Queen Mary University of London’s reactor heats lunar ice to produce “supercritical water,” a state in which oxidation removes contaminants efficiently.
• Lunasonic: The University of Glasgow’s sonoreactor uses ultrasound to split and remove volatile compounds and contaminants from lunar water.

These technologies are designed to withstand the harsh lunar environment, where ice is as hard as steel and contaminated with lunar dust.

Meganne Christian, UK Space Agency reserve astronaut and chair of the Aqualunar Challenge judging panel, explained,

“To sustain a permanent crewed base on the Moon over years and decades, astronauts will need a reliable water supply, which we can also use to produce oxygen and hydrogen.”

Potential Earth Applications

Interestingly, the technologies developed for the Moon hold potential for Earth, particularly in water-stressed regions.

Holly Jamieson, executive director of Challenge Works, noted,

“Water purifying technologies that work in the harsh environment of space can be put to great use on Earth. Autonomous technology that can operate at extreme temperatures without maintenance could be deployed in remote locations around the world.”

Research by the Aqualunar Challenge revealed that 62% of people believe space exploration technologies should have Earth applications, with 56% thinking that using technology in space helps us understand and protect our planet better.

A significant 86% expressed a desire to see lunar water purification technologies adapted for use on Earth.

Implications for Future Lunar Missions

The success of these technologies is vital for future lunar missions, supporting NASA’s Artemis campaign. The ability to purify lunar water not only ensures a sustainable human presence on the Moon but also reduces the need for continuous resupply missions from Earth, which are costly and risky.

Paul Bate further commented on the broader impact,

“Space exploration pushes our knowledge to its limit and spurs innovation, resulting in new products and services that can also benefit citizens on Earth.”

Summary of Finalists and Technologies

Here’s a summary of the ten finalists and their innovative technologies:

A Bright Future for Space and Earth

The finalists of the Aqualunar Challenge will be showcased at the Farnborough Air Show, where their groundbreaking work will be highlighted. The collaboration between the UK and Canada exemplifies how international partnerships can drive technological innovation for space exploration and Earth applications alike.

This initiative by the UK Space Agency not only pushes the boundaries of space technology but also promises advancements that could benefit our planet.

The journey to establish a sustainable lunar base is underway, bringing us closer to realising the dream of long-term human presence on the Moon.
