Why do we care about poor little Spirit?
A robot is shutting down; why all the fuss?
My theory, assuming you might want to hear it—
It’s not just a bot: it’s a real part of us.

For over six years, I could wander a planet;
This rover named Spirit would act as my eyes!
Much more than suspected, back when they began it,
So, yes, I’ll be sad when the poor creature dies.

You say, “it’s a robot—it never was living!
It’s metal and silicon, lenses and gears!
Exploring the surface of Mars, unforgiving,
Controlled from a distance, for over six years!”

Of course, this is true. It’s a robot, just driving;
It just blindly does what it’s programmed to do.
But it does so where I have no hope of surviving,
And when it shuts down, then I’m blind on Mars, too.

I think it is good that the “death” of this rover
Is met with emotion—a tear, or a frown.
We all hit the off-switch, when our time is over…
I hope you’ll feel likewise when I power down.
