Four Sealed In Chamber For Nasa Study

Four people who have been sealed inside a giant can for more than two weeks as part of a NASA study must record every drop of water they use and are limited to one 30-second shower per day.

Body odor is sometimes a problem, but otherwise everything is fine and the accommodations are quite plush, the occupants said Friday.

The three aerospace engineers and one scientist are recycling all their air and water, including urine, in a demonstration of life-support equipment that might one day be used on moon bases or trips to Mars. They plan to spend one month cooped up like this. The three men and one woman get Sundays off.
