This picture brings to mind many science fiction stories and songs I have read and sung. I used to dream about being an astronaut and traveling to the far reaches of our solar system, then striking out for uncharted space. This is the kind of vision I would have when I imagined exploring the galaxy in a space vehicle. I can almost feel the immense loneliness of looking back at a planet containing everyone I know, and eight billion other humans.
The truth is, this picture was taken by a camera on board a man-made vehicle in orbit around the planet Saturn. The photo shows Saturn, the rings of Saturn, and Earth as a tiny blue dot just to the right of centre in the picture (the bright one). It was taken by the Cassini probe built by NASA and sent to a distance of 1.4 billion km from earth. This is of course still within our solar system; yet, it is hard to imagine distances larger than this.
Elton John sang about the loneliness of space in the song Rocket Man. I wonder what he would think of the photo.
Rocket Man (listen to it here)
Elton John and Bernie TaupinShe packed my bags last night, pre-flight
Zero hour, nine a.m.
And I’m gonna be high as a kite by thenI miss the Earth so much, I miss my wife
It’s lonely out in space
On such a timeless flightAnd I think it’s gonna be a long, long time‘til touch down brings
me round again to find I’m not the man they think I am at home
Oh no, no, no, I’m a rocket man
Rocket man, burning out his fuse up here aloneMars ain’t the kind of place to raise your kids
In fact it’s cold as hell
And there’s no one there to raise them if you didAnd all the science, I don’t understand
It’s just my job five days a week
A rocket man, a rocket manAnd I think it’s gonna be a long, long time ‘til touch down brings
me round again to find I’m not the man they think I am at home
Oh no, no, no, I’m a rocket man
Rocket man, burning out his fuse up here alone
