"The dominant theory of the moon's origin proposes that it arose after the collision of a Mars-sized planet with a proto-Earth some 4.5 billion years ago. Some of the material ejected by that impact clumped together and solidified to form the satellite that orbits Earth today."
"Half a century ago it was believed that the moon was completely dry. Scientists have since established that there is ice in the permanently shadowed regions, indicating that the moon may have more water than previously thought."
"Direct access to new, unaltered rocks, combined with modern analysis techniques, could provide much stronger evidence regarding the moon's origin. The hard part will be getting there; the rest is science."
For decades, the moon was perceived as a barren landscape, but new missions reveal its complexity. NASA's Artemis program aims to establish a sustained lunar presence, starting with Artemis IV landing astronauts on the surface. This initiative will provide abundant samples and advanced technology to address unresolved questions about the moon's origin and water presence. The dominant theory suggests the moon formed from a massive collision, but new samples could strengthen this hypothesis. Additionally, the moon's water content, previously underestimated, is now a focus for future exploration.
