The Earth and our Moon from Voyager 1

"There is a tide in the affairs of men, 
Which taken at the flood, leads on to fortune. 
Omitted, all the voyage of their life is bound in shallows and in miseries. 
On such a full sea are we now afloat. 
And we must take the current when it serves, or lose our ventures." 

-William Shakespeare



This picture of the Earth and Moon were taken by the Voyager 1 spacecraft from a distance of 7.25 million miles (~11.66 million km). Taken on 18 September 1977 (when I was -6 years old!), this picture as the very first ever taken that showed the Earth and the Moon in one single frame.

Voyager 1 is the most distant piece of human engineering and human exploration. It's fanciful to sit and think sometimes about how far away it really is now. As of the exact time of this writing, Voyager 1 is 20,661,735,297 km from the Earth and still going. The Voyagers and their mission were a hallmark of early space exploration. Now is truly the time for us to work together to take this current of humanity's evolution as a spacefaring species, and find our ventures among the other realms in the cosmic ocean.


(Note: in the picture above, the Moon appears very close to the Earth. However, the Moon is really about as far away from us as 30 times the diameter of the Earth! The picture certainly wasn't taken from equal distances to both Earth and Moon)
