A technology that uses microwaves to melt lunar ice has been developed to provide clean, drinkable water for astronauts.
The technique, which also uses ultrasound to break down contaminants, has won the UK Space Agency-funded Aqualunar Challenge, an international prize for technologies seeking to make human habitation on the lunar surface possible. Countries around the world are planning lunar missions and the UAE’s next goal in space is to place an Emirati astronaut on the surface of the Moon within 10 years.
About 5 per cent of the soil around the Moon’s south pole is estimated to be water frozen as ice. If it can be successfully extracted, separated from the soil and purified, it would make a crewed base viable.
SonoChem System by Naicker Scientific, based in Gloucestershire, England, was named the winner for its innovative use of microwaves and ultrasound to generate millions of microbubbles in melted lunar ice.
The extreme temperature and pressure created within each micro bubble generates free radicals (unstable atoms which are highly chemically reactive) which effectively removes contaminants.
The Aqualunar Challenge is a £1.2 million international prize funded by the UK Space Agency’s International Bilateral Fund.
Nasa has set the goal of establishing a permanent crewed base on the Moon by the end of the decade. Its Artemis programme is supported by the UK Space Agency through its membership of the European Space Agency.
Panel chairman Meganne Christian of the UK Space Agency said the challenge was required as "astronauts will need a reliable supply of water for drinking and growing food, as well as oxygen for air and hydrogen for fuel".
Lolan Naicker, technical director of Naicker Scientific said: "Imagine digging up the soil in your back garden in the middle of winter and trying to extract frozen water to drink. Now imagine doing it in an environment that is -200°C, a nearly perfect vacuum, under low gravity, and with very little electrical power. That’s what we will have to overcome on the Moon.
"If we can make the SonoChem System work there, we can make it work anywhere, whether that’s on Mars’ glaciers, or here on Earth in regions where accessing clean water is still a challenge."
The UK's Science Minister, Lord Patrick Vallance, has said many of these ideas suggested during the challenge could not only fuel future space exploration, but also help improve lives and solve water shortages on Earth.
Naicker Scientific was awarded the £150,000 first prize.
Frank, by father-and-sons team RedSpace, and AqualunarPure, from a team at Queen Mary University – both from London – were named runners-up.
AqualunarPure's system would use a reactor to melt lunar ice to separate the dust and rock particles, then heats it to more than 373°C at 220 bars of pressure to turn it into “supercritical water” – not a solid, liquid or gas, but a fourth state that appears like a thick vapour – in which oxidation will remove all the contaminants in one step.

Sole survivors
- Cecelia Crocker was on board Northwest Airlines Flight 255 in 1987 when it crashed in Detroit, killing 154 people, including her parents and brother. The plane had hit a light pole on take off
- George Lamson Jr, from Minnesota, was on a Galaxy Airlines flight that crashed in Reno in 1985, killing 68 people. His entire seat was launched out of the plane
- Bahia Bakari, then 12, survived when a Yemenia Airways flight crashed near the Comoros in 2009, killing 152. She was found clinging to wreckage after floating in the ocean for 13 hours.
- Jim Polehinke was the co-pilot and sole survivor of a 2006 Comair flight that crashed in Lexington, Kentucky, killing 49.

Ten tax points to be aware of in 2026
1. Domestic VAT refund amendments: request your refund within five years
If a business does not apply for the refund on time, they lose their credit.
2. E-invoicing in the UAE
Businesses should continue preparing for the implementation of e-invoicing in the UAE, with 2026 a preparation and transition period ahead of phased mandatory adoption.
3. More tax audits
Tax authorities are increasingly using data already available across multiple filings to identify audit risks.
4. More beneficial VAT and excise tax penalty regime
Tax disputes are expected to become more frequent and more structured, with clearer administrative objection and appeal processes. The UAE has adopted a new penalty regime for VAT and excise disputes, which now mirrors the penalty regime for corporate tax.
5. Greater emphasis on statutory audit
There is a greater need for the accuracy of financial statements. The International Financial Reporting Standards standards need to be strictly adhered to and, as a result, the quality of the audits will need to increase.
6. Further transfer pricing enforcement
Transfer pricing enforcement, which refers to the practice of establishing prices for internal transactions between related entities, is expected to broaden in scope. The UAE will shortly open the possibility to negotiate advance pricing agreements, or essentially rulings for transfer pricing purposes.
7. Limited time periods for audits
Recent amendments also introduce a default five-year limitation period for tax audits and assessments, subject to specific statutory exceptions. While the standard audit and assessment period is five years, this may be extended to up to 15 years in cases involving fraud or tax evasion.
8. Pillar 2 implementation
Many multinational groups will begin to feel the practical effect of the Domestic Minimum Top-Up Tax (DMTT), the UAE's implementation of the OECD’s global minimum tax under Pillar 2. While the rules apply for financial years starting on or after January 1, 2025, it is 2026 that marks the transition to an operational phase.
9. Reduced compliance obligations for imported goods and services
Businesses that apply the reverse-charge mechanism for VAT purposes in the UAE may benefit from reduced compliance obligations.
10. Substance and CbC reporting focus
Tax authorities are expected to continue strengthening the enforcement of economic substance and Country-by-Country (CbC) reporting frameworks. In the UAE, these regimes are increasingly being used as risk-assessment tools, providing tax authorities with a comprehensive view of multinational groups’ global footprints and enabling them to assess whether profits are aligned with real economic activity.
