looking at earth from mars

But remember this: The picture above was taken by a machine made by humans, and it’s sitting on the surface of another world. It took hundreds of people thousands of worker-years to imagine it, lobby for it, create it, loft it, and land it on Mars. You can’t see that in the picture because the camera was turned the other way. But if you can step out of the picture in your mind and simply turn around, you’d see that rover on the Martian dust, a testament to human curiosity, the drive to explore, and the need to leave the nest for parts unknown.
