Many myths, theories, and hypotheses have emerged throughout history to explain its origin; however, until 1970s there were neither adequate tools nor direct samples to test these hypotheses. Thanks to the return of lunar samples via NASA’s Apollo missions, the revolutionary “Giant Impact” theory was proposed and gradually received full acceptance. It was believed that the question of lunar formation had finally been answered. However, in the past decade, ultra-high precision isotopic analyses of lunar samples have begun contradicting some predictions of the “Giant Impact” theory, challenging the canonical view of the formation of the Moon. We are in the midst of a crisis, an “isotopic crisis" regarding the origin of the Moon.  Read more...
