The experts relied on information gathered from lunar samples and images captured by the Chang’e 5 mission, and published their findings in the scientific journal Nature Communications.
Scientists have been able to identify at least two sources of origin: one water brought by solar winds and another autochthonous.
The region where the Chang’e 5 mission landed contained minerals that had native traces of hydroxyl, which, made up of one atom of hydrogen and one atom of oxygen, is the main ingredient of water. .
Minerals collected by the Chang’e 5 mission contain fewer crystal remnants, which experts associate with solar winds, one of the possible sources of water on the Moon’s surface.
The presence of crystals in these new samples is a third smaller than that recorded in evidence collected by the US Apollo 11 mission.
One of the objectives of the Chang’e 5 mission was precisely to investigate the existence of lunar water, a key element in understanding the formation and evolution of the Earth’s natural satellite.
The Chang’e program began with the launch of a first probe in 2007.
In recent years, Beijing has invested heavily in its space program and achieved milestones such as successfully landing a probe on the far side of the Moon in January 2019, a feat no country has ever achieved.
