# Most of the Moon's Water Likely Remains Chemically Bound in Its Deep Interior New research confirms the presence of water in the Moon's interior. - **Source:** [Phys.org - latest science and technology news stories](https://brifing.si/source/8b0f98da-d179-4c93-871f-7ac460bf9c61) - **Published:** 2026-07-14 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/da48224e-241b-4630-9b42-45560bf54611 ## Old View on the Moon's Water For many years, it was believed that the Moon was dry and contained almost no water. This view was based on the analysis of rock samples brought back from the Moon. ## The 2009 Discovery NASA's LCROSS mission detected water ice in the permanently shaded regions of the Moon's south pole. This discovery changed the old view that the Moon was dry. ## Source of Water Ice The permanently shaded regions at the Moon's south pole are protected from sunlight, allowing water ice to persist. These regions represent an important area for the Moon's water resources. ## Water in the Depths New research shows that water in the Moon's interior is chemically bound. This water is located much deeper than the Moon's surface. ## NASA's Role NASA is conducting various missions to understand the Moon's water resources. The LCROSS mission is considered one of the most important steps in these efforts. ## Future Explorations The discovery of the Moon's water resources is of great importance for future space missions. These discoveries could contribute to the goal of establishing a permanent human presence on the Moon. ## Sources covering this story - https://phys.org/news/2026-07-moon-chemically-bound-deep-interior.html — --- _Summary written by Brifing from the original reporting.
