This is really a wonderful info!! You have made me remember the history of how Carl Sagan managed to convince the NASA to reverse the Voyager and take a picture to the Earth... when the probe was in Saturn too!!
In first place, he encouraged to make this with these words:
"It had been well understood by the scientists and philosophers of classical antiquity that the Earth was a mere point in a vast, encompassing cosmos—but no one had ever seen it as such. Here was our first chance, and perhaps also our last for decades to come."
If we consider that the original picture was taken by the Voyager in 1990, more than two decades have actually passed away!! Now, we have the opportunity of thinking again about our actual place in the Universe:
"I"t has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. It underscores our responsibility to deal more kindly with one another, and to preserve and cherish the only home we've ever known.
I learned about this wonderful story from Google News this morning - the first story seemed to come from Space.Com via FoxNews (of all unlikely sources to break a technology story) at 9:15 am on July 19th.
@Max, From what I've heard, everyone who has gone into space and seen the Earth below them has undergone a life-changing experience (even bigger that when I first discovered the power of beer).
Maybe for most people. Yet, some people may be beyond hope. I can see the jokes on Saturn now: is that really earth-shine or is that just so-and-so's (--insert favorite boviator's name here--) ego glowing?
