# Studies question feasibility of large-scale Moon water extraction

A 2025 review of 27 extraction approaches found no demonstration adequate to scale up to operationally useful tonnes.

Two 2025 studies question whether lunar water can be extracted at an operationally useful scale, a prospect NASA's Lunar Trailblazer press kit puts at up to 600 million metric tonnes of ice in permanently shadowed regions.[^1]

The first, a 2025 open-access review in Space and Planetary Resources, examined 27 simulated or experimentally tested extraction approaches and found inconsistent definitions and reporting, with no demonstration adequate to show scale-up to operationally useful tonnes.[^2]

A separate 2025 value-of-information study found that uncertainty in deposit composition and technology performance is central to the business case for lunar water extraction, and argued that surface prospecting can therefore be worth more than its mission cost in representative scenarios.[^3]

4. NASA states lunar phases are caused by the Moon's position relative to Earth and the Sun during its 29.5 day orbit. ([Mashable](https://mashable.com/science/moon-phase-today-sept-21-2026), News)
5. A telescope will reveal the Apollo 14 landing spot, Descartes Highlands, and Rima Hyginus on the Moon on 2026-09-21. ([Mashable](https://mashable.com/science/moon-phase-today-sept-21-2026), News)
6. The Moon orbits Earth in about 29.5 days, causing the visible illuminated portion to change and creating the lunar phases. ([Mashable](https://mashable.com/science/moon-phase-today-sept-20-2026), News)
7. According to NASA, the lunar phase seen is determined by the Moon's position relative to Earth and the Sun. ([Mashable](https://mashable.com/science/moon-phase-today-sept-20-2026), News)
8. With a telescope, observers can see the Apollo 11, 16, and 17 landing sites on the Moon. ([Mashable](https://mashable.com/science/moon-phase-today-sept-20-2026), News)
