The moon has been a source of wonder and mystery ever since the first cave dwellers turned their eyes to the glowing orb in the night sky. But for the past 50 years, we have been able to explore our planet's only natural satellite as never before. From the Soviet's first flyby of the moon in 1959 to the future missions of exploration, we now understand the moon perhaps better than any other celestial body.
