    If you knew a bottle of water had been recycled from urine (尿), would you drink it? Astronauts at the International Space Station (ISS) may soon do so. The USNASA (美国宇航局) said it would use a high-tech machine to recycle wastewater at the ISS. The machine will recycle everything from sweat, the water for washing hands and brushing teeth, shower water and even urine, to make drinking water.

It will save NASA millions of dollars each year. The machine will be sent to the ISS in October2022. NASA expects it will recycle about 93% of all water used on the station. Will the water be clean? Scientists say it will be very difficult to make the wastewater clean. But the recycled water is thousands of times better than the water from a city tap, scientists say.
