In the darkest and coldest arctic regions of the moon, direct evidence of water ice was reached directly. Properly distributed ice slabs are probably quite old. In the South Pole region, the ice is mostly concentrated in the craters, while it is quite scattered in the north.
The equipment of the Chandrayaan-1 spacecraft, launched by the Indian Space Research Organization in 2008, was at the level to confirm the presence of the ice in the Moon. Thus, the discovery could not only take advantage of the reflector property of the ice, but also by measuring the degree of absorptivity of its molecules with infrared light. The vehicle was able to separate liquid water, ice or steam at this rate.
A large part of the newly discovered water ice is found in the shadows of the craters near the poles where temperature does not reach above -250 Fahrenheit (-150 Celsius). Since the angle of rotation of the Moon is very small, the sunlight never reaches these regions.
Previous observations predicted ice could be in the craters around the southern pole of the Moon. But these could also be explained by other factors such as reflective Moon land.
The presence of ice on the surface means reaching the water comfortably in future probing missions. So you will not need to dig to reach the water below the moon‘s surface.
Finding more information about ice, how to get there and protect the ice will be the main reason for traveling back to the Moon.
