In space it is necessary to save absolutely everything. The International Space Station, the cradle of scientific exploration on the outskirts of Earth, is proof of this. For more than two decades, astronauts have come to the NASA ship to develop all kinds of productive research for our world and for the stay of people in conditions different from those of the planet.
Hydration has to be one of the main points in this aspect. It is complex to send water to this place where there is no possibility of it being generated naturally.
A note from the portal Engadget rescues an explanation of how NASA takes full advantage of all the resources of the International Space Station (ISS) and without losing a drop of anything.
NASA implemented something called the International Space Station Environmental Control and Life Support System (ECLSS). Through this process they are recycling 98 percent of all the water the astronauts have on the ISS.
Using a system called advanced dehumidifiers, they are able to capture the moisture that station crews breathe and sweat while they work.
They do the same with urine, in a system they call the Urine Processor Assembly. With this they recover what is released in a vacuum and after a distillation mechanism they are able to produce water because in the components released by the astronauts there is a lot of H2O that can be recovered.
“This is a very important step forward in the evolution of life support systems. Let’s say you collect 100 pounds of water at the station. You lose two pounds of it, and the other 98 percent just keeps going round and round. Keeping that running is a pretty impressive achievement,” said NASA’s Christopher Brown.
It is completely clean and healthy
Scientists say that the same thing they are doing on the ISS is what they do with Earth’s drinking water, only that the process is recorded in space.
“The processing is fundamentally similar to some terrestrial water distribution systems, only it is done in microgravity. The crew is not drinking urine; they are drinking water that has been reclaimed, filtered and cleaned in such a way that it is cleaner than what we drink here on Earth,” explained Jill Williamson, NASA ECLSS water subsystems manager.
