Buzz Aldrin on the Moon
Apollo 11 astronaut Buzz Aldrin became the second person to set foot on the moon on July 20, 1969. Commander Neil Armstrong, the first on the moon, captured this image—one of the most famous photographs of the 20th century—soon after the lunar lander Eagle touched down in the Sea of Tranquility.
