The rover has taken a picture to show what Earth looks like from more than 100 million miles away. From Mars, our vibrant world of blue and green is reduced to little more than a spec in the sky, barely distinguishable from the stars. Curiosity took the poignant image during its 529th day exploring the Red Planet. “Look back in wonder,” it Tweeted. “My 1st picture of Earth from the surface of Mars.”
The photograph echoes the famous “pale blue dot” image taken of Earth by the Voyager 1 spacecraft back in 1990. The probe had completed its primary objectives and was on its way towards the edge of the solar system when legendary astrophysicist Carl Sagan requested that it be turned around to take a picture of our home planet from across a vast expanse of space.
Take a real good look at that. That is what Earth looks like from our 2nd closest neighbour in our solar system. We are a tiny blue speck of dirt and on that tiny blue speck of dirt is even tinier specks of living organisms that in the big picture are no bigger than single celled organisms if that. Do you see where I am going with this?
