Carl Sagan * Scientist * Child Prodigy

7. Pioneer Plaques
.
Many people know that Pioneer 10 and Pioneer 11 spacecrafts carry metal plaques that carry a message from mankind.
.
But not many know that it was Carl Sagan, together with Frank Drake (yes, the man who came up with the Drake Equation that attempts to estimate the number of alien civilization in our galaxy), that designed the plaque.
.
The controversial artwork, which featured a nude man and woman, was drawn by Sagan's then-wife Linda Salzman Sagan.
.

After the Pioneer Program, NASA put a Golden Record aboard the two Voyager spacecrafts, which included a greeting "Hello from the children of planet Earth."
.
That was recorded by then six-year-old Nick Sagan, Carl's son.
