First Man (PG-13~ 2018) 2 Hrs. 21 Min.
Hoping to reach the moon by the end of the decade, NASA plans a series of extremely dangerous, unprecedented missions in the early 1960s. Engineer Neil Armstrong joins the space program, spending years in training and risking his life during test flights. On July 16, 1969, the nation and world watch in wonder as Armstrong and fellow astronauts Buzz Aldrin and Michael Collins embark on the historic Apollo 11 spaceflight.

Return to Apollo:
Geologic evolution of a young moon
Speakers: Lars Borg, LLNL

This talk will discuss the age relations of samples returned by the Apollo space missions from 1969 to 1972 and how they constrain the origin and evolution of the Earth’s Moon. The basic geologic model for the origin and evolution of the Moon that has been developed based on its the physical and chemical properties which predicts that the Moon’s crust and mantle should have formed at the same time. Historical age determinations completed on Apollo samples do not support this prediction and instead demonstrate a wide range of ages. New chronologic measurements completed using state-of-the-art methods at LLNL reveal that many of the historical age determinations are erroneous. The new measurements demonstrate that the Moon’s mantle and crust formed contemporaneously between 4.33 and 4.38 billion years ago.

Lars Borg is a cosmochemist in the Nuclear and Chemical Sciences Division at LLNL. Dr. Borg received a Ph. D. in Isotope Geochemistry from University of Texas, Austin. He has completed numerous lunar chronology investigations dating crustal rocks, basalts, and impact melts and applied these ages to constrain primordial differentiation, the timing of basin formation, and the duration of basaltic magmatism on the Moon. His research focus is on the primordial differentiation of the terrestrial planets and asteroids, the petrogenesis of lunar, Martian, and terrestrial basalts, and the nucleosynthesis of elements found in the Solar System, which has resulted in over 70 peer-reviewed publications.
