Callisto

The Oldest Face

JupiterIoEuropaGanymedeCallisto
Callisto around Jupiter, with Io, Europa, Ganymede. Drawn to be seen, not to scale: the order and the direction are real.

Callisto: the most heavily cratered object known, whose surface has barely changed in four billion years.

What the song is built on

  • The most heavily cratered object known
  • Its surface has barely changed in four billion years
  • Far enough from Jupiter to escape the worst radiation
  • Often named as the safest place to put a base in the Jupiter system

Established astronomy. The music is an interpretation of it — see the curatorial policy.

SoundStill ambient with wide cavernous reverb, sparse low piano notes, almost no rhythm, distant whispered vocal, 58 BPM, ancient and motionless

Lyrics
[Intro] Nothing here has happened In four billion years [Verse 1] Every crater ever given me Is still exactly where it fell No volcano came to bury them No ocean rose to swell I am the record nobody erased The oldest face the system wears A page that took four billion years to fill And not one line repairs [Chorus] The oldest face, the longest memory I kept the marks that others lost Everything that hit this neighbourhood Is written here, and I have paid the cost [Verse 2] Far enough from Jupiter That the radiation thins and calms They say if people ever come this way They'd build their first house in my arms Valhalla spreads across my side Rings within rings from one old blow A bullseye two thousand kilometres wide From something nobody saw go [Bridge] Quiet is not the same as empty Still is not the same as dead Maybe an ocean waits beneath me too Keeping its own counsel instead [Final Chorus] The oldest face, the longest memory I kept the marks that others lost Everything that hit this neighbourhood Is written here, and I have paid the cost [Outro] Nothing here has happened And that is the story
