We dispatched them to explore
the outer planets, where we
can't go ourselves: observe rings,
moons, alluring mystery.

Beyond Neptune one final
image, of a pale blue dot
clasped gently in rays of light.
Thereafter, night. They can not

go back: blinded, must journey
on, two tiny travellers
alone on separate paths
through the vast, cold universe.

They are not – yet – lost in space.
We can still trace where they are,
faint signals from the darkness
telling us how fast, how far;

but not for long. Soon, voiceless,
they'll traverse interstellar
space, bearing golden records –
earth sounds, earth words. Who will hear?

A version of this awdl gywydd (a traditional Welsh poetic form) was published on The Wombwell Rainbow in November 2022. 

The phrase ‘pale blue dot’ was used by Carl Sagan to describe an image of Earth taken by Voyager 1 on 14th February 1990, shortly before the spacecraft’s cameras were permanently switched off to conserve power.
