The NASA Insignia (more commonly referred to as the "meatball") reflects the history and tradition of the Agency and is used in all of the Agency's day-to-day communications materials. Designed in 1959 by former NASA employee James Modarelli, the NASA Insignia contains the following elements:
The sphere represents a planet
The stars represent space
The vector represents aeronautics
The orbit represents space travel

The recent discovery of a little-known official NASA "logo"-- the official insignia of the entire Apollo Program to the Moon-- now raises the level of the mystery veiling Ancient Egypt to unprecedented levels... and forces us to ask: "What could be 'the Link'-- between official, 'scientific NASA,' and... 'a thousands-of-years-old, religious mythology direct from ancient Egypt... and the Pyramids!?'--
"Via an official 'Apollo' Logo-- which is none other than... 'Osiris'... the constellation of 'Orion,' and... the Pyramids?"
