A song of mine from 2006 that’s ostensibly about a plausible spaceship, but really about caring a whole lot about something bigger than yourself.
BONUS: This song, though having a sci-fi bent, does not sound like filk. If you don’t know what filk is, just trust me, you’re welcome.
Appears on my album Evidence of Absence.
Near-Earth Object 
One of my favorites from Evidence of Absence! Recommended!
