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:
“Reasoning with a drunkard is like
Going under water with a torch to seek for a drowning man.”
—Tiruvalluvar (c. 5th century A.D.)
“Man is but a reed, the feeblest one in nature; but he is a thinking reed. The entire universe need not arm itself to crush him—a vapor, a drop of water suffices to kill him. But if the universe were to crush him, man would still be nobler than that which killed him, because he knows that he dies and the advantage which the universe has over him; the universe knows nothing of this.”
—Blaise Pascal (1623–1662)
“As the hart panteth after the water brooks, so panteth my soul
after thee, O God.”
—Bible: Hebrew Psalm XLII (l. XLII, 1)
