This poem had many changes, including considerable rearrangement. Rather than highlighting the bits that were just changed, here I have highlighted the bits I used. Often they occur in different lines or positions within a line, so my normal markings would be useless. The original title was The Rings At Dawn.

    This moon, asleep in night, cold frozen Titan,
Moves slowly through the darkness, shadows creep
Across its face, above its oceans deep,
As overhead, a planet floats: great Saturn.
Her atmosphere an ever changing pattern
Of churning clouds, her sky will never sleep,
For now with gold her edge begins to weep, 
Dawn is arriving, soon the world will lighten.

    And now the sun is here, pure light it brings,
The yellow flames shoot through the air, they flow
Like angels through the sky on fiery wings;
Stricken blue and red, a mighty rainbow
Hastens through the heavens, the planet's rings 
Hit by the sun: the infinite halo.
