The prior Endeavor Space Shuttle article I posted omitted to report the $250 million gizmo on board to be used during a featured experiment.
This gizmo converts waste liquid into drinking water:
"We did blind taste tests of the water. Nobody had any strong objections. Other than a faint taste of iodine, it is just as refreshing as any other kind of water," NASA's lead urinary engineer Bob Bagdigian told the Daily Telegraph
But the current aim is for 92% of all the water drunk on board to be produced by the crew's urinary tracts and the moisture in the air- some of which might be created, one supposes, by sweating crew members.
Don't get queasy-I think the same process is used for bottled and tap water.
