The presence of large quantities of water on the Moon would be an important factor in rendering lunar habitation cost-effective since transporting water (or hydrogen and oxygen) from Earth would be prohibitively expensive. If future investigations find the quantities to be particularly large, water ice could be mined to provide liquid water for ...
The Moon is Earth's only natural satellite, orbiting at an average distance of 384 399 km (238,854 mi; 30 Earths across).It faces Earth always with the same side.This is a result of Earth's gravitational pull having synchronized the Moon's rotation period with its orbital period (lunar month) of 29.5 Earth days.
The geology of the Moon (sometimes called selenology, although the latter term can refer more generally to "lunar science") is quite different from that of Earth. The Moon lacks a true atmosphere , and the absence of free oxygen and water eliminates erosion due to weather .

The deuterium to hydrogen ratio for ocean water on Earth is known very precisely to be (1.5576 ± 0.0005) × 10 −4. [36] This value represents a mixture of all of the sources that contributed to Earth's reservoirs, and is used to identify the source or sources of Earth's water.
But this latest discovery, scientists say, is the first time water in its molecular form, H2O, has been found in physical samples – and, importantly, it was retrieved from a part of the moon ...
Currently, cold surface bodies of liquid are found on two worlds in the Solar System, Earth and Saturn's moon Titan. [1] Earth is the only planet with liquid water on its surface. The other "oceans" are found under thick covers of surface ice. If both liquid and frozen water are counted, Earth ranks fifth in volume of its oceans. [2]
In a report published in the journal Nature Geoscience on Monday, March 27, 0223, scientists announced they have discovered a new and renewable source of water on the moon for future explorers in ...
