Apollo 11: 50 Years LaterOn Jan. 9, 1969, NASA announced the prime crew of the Apollo 11 lunar landing mission. This portrait was taken on Jan. 10, the day after the announcement of the crew assignment. From left to right are lunar module pilot Buzz Aldrin, commander Neil Armstrong; and command module pilot Michael Collins. (Image: NASA)

Apollo 11: 50 Years LaterNeil Armstrong trained for the Apollo 11 mission at NASA Langley's Lunar Landing Research Facility on equipment that cancelled all but one-sixth of Earth's gravitational force. Armstrong offered perhaps the greatest tribute to the importance of his training when asked what it was like to land on the moon, replying, "Like Langley." (Image: NASA)

Johnson and then-current Vice President Spiro Agnew are among the spectators at the launch of Apollo 11, which lifted off from Pad 39A at Kennedy Space Center at 9:32 am EDT on July 16, 1969. The crew, the first of the Apollo missions to land on the moon, safely returned to Earth on 37 years ago this week on July 24, 1969 (Image: NASA)
Apollo 11: 50 Years LaterThe American flag heralded the launch of Apollo 11, the first Lunar landing mission, on July 16, 1969. The massive Saturn V rocket lifted off from NASA's Kennedy Space Center with astronauts Neil A. Armstrong, Michael Collins, and Edwin "Buzz" Aldrin at 9:32 a.m. EDT. Four days later, on July 20, Armstrong and Aldrin landed on the Moon's surface. (Image: NASA)

Inside the module were Commander Neil A. Armstrong and Lunar Module Pilot Buzz Aldrin. The long rod-like protrusions under the landing pods are lunar surface sensing probes. (Image: NASA)

Apollo 11: 50 Years LaterAstronaut and Lunar Module pilot Buzz Aldrin is pictured during the Apollo 11 extravehicular activity on the moon. He had just deployed the Early Apollo Scientific Experiments Package. In the foreground is the Passive Seismic Experiment Package; beyond it is the Laser Ranging Retro-Reflector (LR-3). (Image: NASA)
Apollo 11: 50 Years LaterThis photograph of the Lunar Module at Tranquility Base was taken by Neil Armstrong during the Apollo 11 mission, from the rim of Little West Crater on the lunar surface. Armstrong's shadow and the shadow of the camera are visible in the foreground. This is the furthest distance from the lunar module traveled by either astronaut while on the moon. (Image: NASA)

Aldrin Jr., lunar module pilot of the first lunar landing mission, poses for a photograph beside the deployed United States flag during an Apollo 11 extravehicular activity (EVA) on the lunar surface. The Lunar Module (LM) is on the left, and the footprints of the astronauts are clearly visible. (Image: NASA)
