We've journeyed many months through ill-lit space,
And now this moon, Callisto, we have found;
Of ice it's made, to Jupiter well bound,
The hammer of that god, his mighty mace.
So now at last we land upon its face,
First men to trace this frigid, rimy ground,
Its surface flaunts its frost, grown all around
Each step we take is glacial in its pace.

    Our eyes are skyward pulled, our gaze is drawn:
Vast Jupiter looms swollen in the air,
A massive globe that's stretched to fill the eye.
Across from east to west it floats with scorn
The planet hovers high, enduring there,
And fills all sight with mountains in the sky
