Phobos

Countdown Moon

MarsPhobos
Phobos around Mars. Drawn to be seen, not to scale: the order and the direction are real.

Phobos: Mars's inner moon, circling three times a day and spiralling in towards its destruction.

What the song is built on

  • It circles Mars three times a day, rising in the west
  • It is spiralling in, and will break apart in tens of millions of years
  • Only about 22 km across, shaped like a potato
  • Named for fear; its brother moon Deimos for dread

Lyrics
[Intro] Tick. Tick. Closer. [Verse 1] Twenty-two kilometres of broken rock Shaped like something thrown, not made Six thousand kilometres over Mars Closer than any moon has stayed Three times around in a single day I rise in the west and set in the east Too fast for the sky to follow me A moon in a hurry, a moon on a leash [Chorus] Countdown moon, countdown moon Every year I fall a little more Fifty million years, they say Then a ring where a moon was before [Verse 2] Stickney crater takes a third of me From a blow that should have ended it all Grooves run out across my face Stress fractures, the first signs of the fall Named for fear, my brother named for dread Sons of the god of war Two little rocks that Mars picked up Or made, and no one is sure [Bridge] Mars will wear a ring one day Made of everything I am And nobody will be standing there to see Unless you come, and stay, and plan [Final Chorus] Countdown moon, countdown moon Every year I fall a little more Fifty million years, they say Then a ring where a moon was before [Outro] Tick. Tick. Still here. For now.
