Origin and History of the Moon and Earth Through an Explorer's Eyes

Vortrag

Apollo 17's exploration and observation of geological features in the valley of Taurus-Littrow provide new insights into the origin and history of the Moon and how that knowledge relates to the early history of the Earth. Volatiles associated with orange volcanic glasses indicate that lunar origin by giant impact is unlikely; the age of rock melted by the impact event that formed the 740km diameter Serenitatis Basin helps constrain similar, life-associated events on Earth 3.8 billion years ago; crystalline rocks older than 4.4 billion years define major melting events within the Moon soon after it formed around the sun.
