Water is consumed by crew members through drinking, cleaning activities, EVA thermal control, and emergency uses. It must be stored, used, and reclaimed (from waste water) efficiently since no in-situ sources currently exist for the environments reached in the course of human space exploration.

Famous quotes containing the word water:
“I think of the nestling fallen into the deep grass,
The turtle gasping in the dusty rubble of the highway,
The paralytic stunned in the tub, and the water rising,—
All things innocent, hapless, forsaken.”
—Theodore Roethke (1908–1963)
“A single monk carries his own bucket of water; two monks carry their bucket of water together; but when there are three monks, there is no water at all.”
—Chinese proverb.
“We then entered another swamp, at a necessarily slow pace, where the walking was worse than ever, not only on account of the water, but the fallen timber, which often obliterated the indistinct trail entirely. The fallen trees were so numerous, that for long distances the route was through a succession of small yards, where we climbed over fences as high as our heads, down into water often up to our knees, and then over another fence into a second yard, and so on.”
—Henry David Thoreau (1817–1862)
