Intro music.

00:00:07.000 --> 00:00:12.000
Water recycling research is taking center stage at several NASA facilities.

00:00:12.000 --> 00:00:20.000
New purifying systems are being developed to transform wastewater into potable water suitable for crew consumption and other uses in space.

00:00:20.000 --> 00:00:24.000
In any environment, where humans are involved, they're going to consume water

00:00:24.000 --> 00:00:27.000
to keep alive and they're going to produce contaminated water.

00:00:27.000 --> 00:00:30.000
And if sources of water are limited,

00:00:30.000 --> 00:00:35.000
recycling that contaminated water to produce potable or hygiene water has inherent benefits to it.

00:00:35.000 --> 00:00:40.000
Water counts for about 85% of all the metabolic requirements to keep a human alive.

00:00:40.000 --> 00:00:46.000
So if you were to bring the water along with you you'd have to have a much larger spacecraft.

00:00:46.000 --> 00:00:50.000
And that would have significant impact on the cost."

00:00:50.000 --> 00:00:52.000
To advance the Vision for Space Exploration,

00:00:52.000 --> 00:00:58.000
NASA needs to come up with a way to have enough fresh water to support long-term space missions.

00:00:58.000 --> 00:01:06.000
Shipping from Earth may not be the most economical or practical way to keep our space explorers supplied with the basic necessities of life.

00:01:06.000 --> 00:01:08.000
Water recycling technologies developed by

00:01:08.000 --> 00:01:18.000
NASA will eventually meet these exploration timelines and benefit people here on Earth in need of fresh potable water.

00:01:18.000 --> 00:01:23.000
