Lunar Mysteries Unveiled

Galileo's volcanic theory of lunar craters was challenged by Proctor's impact hypothesis, leading to significant advancements in lunar studies. The Apollo program revealed that moon rocks are around 4.1 to 4.4 billion years old, primarily composed of silicate materials, yet lacking volatile elements like water. While the moon's surface appears dry, evidence of frozen water in polar regions suggests a more complex history, possibly linked to ancient impacts or comets.
