It's funny, they look like a big and little brother, but which one goes into space? The young'n!
The Green Hills of Earth
Let the sweet fresh breezes heal me As they rove around the girth Of our lovely mother planet Of the cool, green hills of Earth.
We rot in the moulds of Venus, We retch at her tainted breath. Foul are her flooded jungles, Crawling with unclean death.
[ --- the harsh bright soil of Luna --- --- Saturn's rainbow rings --- --- the frozen night of Titan --- ]
We've tried each spinning space mote And reckoned its true worth: Take us back again to the homes of men On the cool, green hills of Earth.
The arching sky is calling Spacemen back to their trade. ALL HANDS! STAND BY! FREE FALLING! And the lights below us fade.
Out ride the sons of Terra, Far drives the thundering jet, Up leaps a race of Earthmen, Out, far, and onward yet ---
We pray for one last landing On the globe that gave us birth; Let us rest our eyes on the friendly skies And the cool, green hills of Earth.
