Oh, it is a reference to the probe…

long years, far place
dark nights, dark days
frozen, silent
bearing Earth-songs

force fields, high winds
cold moons, bright rings
hear my signal will you follow?

look back at us
as a speck of dust
darkness our home
bear it through love

last note, last sign
Neptune, Triton
fading signal
choose light… choose love

Voyager, look back
at a pale-blue dot
all we don't know
a flake of snow

dust in a sunbeam, blue dot
so far, so cold

kindness, care for…
our shelter… tender
