in vacant or in pensive mood

What's the last thing you'd love to see before you permanently close your eyes? For Voyager 1, it was a series of photos but the most iconic and undoubtedly the most significant one was this photo below. That small dot is our planet and this photo has been since called the "Pale Blue Dot" and is one of the most searched and coveted photographs in our spacial history.  This was the dream shot of Carl Sagan who was an advisor for Nasa at that time. He had to pitch this idea several times since the Voyager left earth and he was always denied since the photo would have no real scientific value or relevance. Thankfully - this wasn't done for any scientific pursuit but for a more emotional one. The Earth images were taken at 04:48 GMT on Feb. 14, 1990, just 34 minutes before Voyager 1 powered off its cameras forever . What a beautiful and unforgettable Valentíne's day shot the Voyager 1 had provided for mankind. But the image officially was received by the Nasa team
