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.

Famous quotes containing the words absence of, absence, liquid and/or water:
“I feel the desire to be with you all the time. Oh, an occasional absence of a week or two is a good thing to give one the happiness of meeting again, but this living apart is in all ways bad. We have had our share of separate life during the four years of war. There is nothing in the small ambition of Congressional life, or in the gratified vanity which it sometimes affords, to compensate for separation from you. We must manage to live together hereafter. I can’t stand this, and will not.”
—Rutherford Birchard Hayes (1822–1893)
