Analysis of Sailing the Jovian Line

I remember
A time when I Sailed–
 the void between The moons
of Jupiter of old-
From the orbit
Of Io
With a cargo
of sulfur
Fresh from its mines–
To the factories in orbit of callisto
Around the frozen moon
Churning out goods
Ready for the market
All the way to Europa
To resupply the artist
Then finally to Titan a transhumanist retreat
For another maintenance round repeat
Those were the days on the Jovian line
How I wish I never left it behind
