This year marks the 50th anniversary of the Apollo 11 Moon landing in 1969. In all, twenty four courageous astronauts risked their lives while traveling from the Earth to the Moon and back between 1968 and 1972. Twelve of these astronauts actually set foot on the Moon. Yet it is hard to believe that out of this elite group of twelve, only four of the Moon walkers are still alive today. As we prepare for the next wave of Moon walkers in the coming decades, these first twenty four voyagers should forever be remembered for their contributions to the exploration of space as part of the ambitious Apollo Program – an undertaking so bold and difficult, that it has achieved an iconic stature in the history of mankind.
