201950 Years from the first Moon Landing - First Day Cover

Apolo 11 was the first mission to bring people down to the Moon's surface, the fifth mission within the Apolo program with human crew, and the third with human crew flying to the moon. Apolo 11 was launched on July 16, 1969 with a three-member crew made by Neil Armstrong, Edwin Aldrin and Michael Collins. On July 21, 1969, Neil Armstrong became the first man to step into the moon, and soon joined Edwin Aldrin. During that time, Michael Collins was in the command module, in orbit around the moon. The first sentence Neil Armstrong spoke on the surface of the moon and said, "This is a small step for man, but great for mankind."
This event is still very popular in the scientific world as well as in pop culture and several interesting facts about the mission remain relatively unknown.
