Episode 214: Planetary Sciences Institute senior scientist emeritus Bill Hartmann

In 1974, Tucson lunar scientists Bill Hartmann and Don Davis developed the modern theory about how the moon was formed. Hartmann says the latest computer models confirm his analysis that the moon was created from the remnants of a giant object's impact with the Earth 4.5 billion years ago.

Planetary Sciences Institute senior scientist emeritus Bill Hartmann talked with Tim Swindle, director of the Lunar and Planetary Institute at the University of Arizona.
