Parody lyrics: Elizabeth Landau
Notes: ELF stands for Enceladus Life Finder, a proposed mission to Saturn’s moon Enceladus

The probe called ELF would have flown to a moon
That we think could have sings of life in its plume
To Enceladus we had hoped to return
But another spacecraft will be how we learn

No ELF, no ELF, NASA said no to ELF
It’s a mission idea we’ll put back on the shelf
No ELF, no ELF
JPL has no ELF
We have all the Mars rovers, but no ELF
