Flight Maps of Stardust Voyagers: a Poem

I found this image on Google, ascribed to nasa-space-station-info.blogspot.com.
The title of my prose post on this topic was so groovy, I decided to attempt a poem.
Here goes:

The flight maps of stardust voyagers
are imprinted on our bones.

We arrived here from somewhere else,
with scintillation from the Milky Way
still trailing from our limbs.

Andromeda watched our journey
from star to star.
A supernova fired us from Sky to Earth
and, ever since,
we have been searching the heavens,
looking for the map
that will lead us
Home.
