Absence of Liquid Water
Apparent lack of liquid water on Titan's surface has been cited by NASA astrobiologist Andrew Pohorille as an argument against life there. Pohorille considers that water is important not only as the solvent used by "the only life we know" but also because its chemical properties are "uniquely suited to promote self-organization of organic matter". He has questioned whether prospects for finding life on Titan's surface are sufficient to justify the expense of a mission which would look for it.

My fairest, my espoused, my latest found,
Heaven’s last best gift, my ever new delight,
Awake, the morning shines, and the fresh field
Calls us: we lose the prime, to mark how spring
Our tended plants, how blows the citron grove,
What drops the myrrh and what the balmy reed,
How nature paints her colors, how the bee
Sits on the bloom extracting liquid sweet.””
—John Milton (1608–1674)

Botched, it smears the hands, crumbles to dust.
But the thing worth doing well done

and a person for work that is real.”
—Marge Piercy (b. 1936)
