SOLAR SYSTEM

Detailed explanation-1: -First, Astronaut wastewater is captured, such as urine, sweat, or even the moisture from their breath. Then impurities and contaminants are filtered out of the water. The final product is potable water that can be used to rehydrate food, bathe, or drink.

Detailed explanation-2: -Astronauts living and working 400 km above our planet might prefer not to think about it, but the water they drink is recycled from their colleague’s sweat and exhaled breath – collected as condensation on the Space Station’s walls.

Detailed explanation-3: -Drinking water is something many of us take for granted on Earth, but on space missions it is harder to come by. The ISS recycles much of its water using chemicals, but it still relies on sizeable shipments of water from Earth to give its astronauts access to clean water.

Detailed explanation-4: -The goal of NASA’s recycling water system was to reduce the need for supplies to be shipped from Earth. It also means that astronaut crews would be able to endure longer space missions as a result.

Detailed explanation-5: -Astronauts can process small pieces of trash in a high-temperature reactor, which breaks the waste down into water, oxygen, and other gases which the crew can use or vent as needed. Besides the gases, the remainder of the waste is greatly reduced in size, and no longer biologically active.

Detailed explanation-6: -Astronauts involuntarily lose body water during space missions. Body fluid that is usually pulled towards the feet by Earth’s gravity shifts rapidly during spaceflight, moving from the legs into the upper body. This fluid shift increases pressure in the head and torso, and body water loss soon follows.

Detailed explanation-7: -Three of the basic needs of humans on Earth are food, air and water. Humans in space need these things as well. For astronauts on the International Space Station (ISS), these basic needs are met with materials either sent from Earth or recycled on the ISS (air and water).
