This month we are celebrating 20 years of continuous human presence on the International Space Station (ISS)! In honor of this major milestone, we are featuring ISS themed trivia questions. Test your knowledge below!
What percentage of wastewater on the ISS gets recycled by the station's Water Recovery System?
According to NASA, the Water Recovery System onboard the ISS can recycle approximately 93% of the wastewater produced on the station. This efficiency is what allows for larger crews onboard the orbital laboratory. The system works as a purification process, recycling condensation from crew quarters along with astronaut's sweat and urine, to get clean drinking water. Don't worry, though. The recycled water must meet extremely strict purity standards before the astronauts can consume it. The Water Recovery System on station has reduced the crew's reliance upon cargo spacecraft to deliver water. Systems such as this will be of vital importance as astronauts travel further into deep space to the Moon, Mars, and beyond. Thus, teams of NASA engineers continue to improve the system to increase its efficiency and lifespan. Earlier this year, the station's Water Recovery System received an important upgrade which is supposed to increase the prolonged dependability of the system's hardware. As astronauts prepare to travel farther from home, getting these systems right will ensure that astronauts can access clean water for long-duration missions.
