In July, 1960 NASA was preparing to implement its long range plans for a manned lunar project. The name "APOLLO" was chosen by NASA from ancient Greek mythology. Apollo was the god of archery, prophecy, poetry, music and god of the Sun. On the emblem, the Earth and Moon flank a large stylized letter "A" against a background of stars. Constellation Orion, The Mighty Hunter, is positioned so its three central stars form the bar of the letter "A". The face of the Moon represents the mythical god, Apollo.
