President John F. Kennedy issued the challenge to America in a speech to Congress in 1961: Land a man on the moon within the decade. This HBO mini-series, produced by Tom Hanks, chronicles the story of NASA's efforts to carry out the vision. Episode 10 looks at what NASA learned about the composition of the moon and its history. The physical specimens gathered by the astronauts held the key to the answers to those questions. ~ Rose of Sharon Winter, Rovi
