Pale Blue Dot


Background: Pale Blue Dot is a picture of the earth taken from the Voyager 1 space probe from a distance of almost 4 billion miles (6 billion kilometers). After the probe had completed it’s mission and was leaving the solar system, it was sent one last command – to turn around a take a picture of the earth. You can see it there, in a beam of light. A tiny speck of blue.

The great astronomer and humanitarian, Carl Sagan, coordinated the project for NASA. Some did not want to attempt it, but Sagan pushed for it anyway and in 1990 (February 14) it finally became a reality.

According to Wikipedia in his autobiography Isaac Asimov described Sagan as one of only two people he ever met whose intellect surpassed his own.

One of the great videos of all time from one of the great minds of all time.
