From the recording Planetarium (Remastered)
The Mars rover 'Spirit', stuck helplessly in the fine Martian sand, bravely faces its final sunset before the Martian winter sets in, forcing it to shut down its battery and conserve its power until Spring arrives, or maybe forever. A lonely saxophone and hammond organ accompanies it on its last night 'alive' in a celebration of its life spent happily roving the Martian terrain, its twin and only other operational mechanical resident of the red planet, Opportunity, being thousands of miles away in the other hemisphere, unaware of its sibling's plight.
