NATURE CALLS, EVEN IN SPACE. And when it does, it's not always easy for astronauts floating in a microgravity environment to heed its call without creating some mess.
But as scientists set their sights on longer journeys to the Moon and beyond, they want to make sure astronauts enjoy some basic comforts on their spacecraft. Which is why NASA is launching a brand new toilet to the International Space Station (ISS) on Tuesday — a much-welcomed upgrade to the everyday life onboard.
The new space toilet launched onboard a private cargo spacecraft from NASA's Wallops Flight Facility in Virginia at 10:27 p.m. last night.
The toilet, which is officially named the Universal Waste Management System, is worth $23 million. It is 65 percent smaller and 40 percent lighter than the toilet currently being used on the ISS, although it is designed for larger crews.
NASA designed the loo with the upcoming Artemis mission in mind. The astronauts onboard the ISS will test it out, providing feedback to the space agency so that they can improve on the design before installing it on the Orion spacecraft for the 10-day journey to the Moon.
As NASA also aims to send the first female astronaut to the Moon, the toilet was designed for better use for women, too.
The space toilet includes a urine funnel, where the urine is filtered, processed and turned to water that the astronauts use afterwards.
“We recycle about 90 percent of all water-based liquids on the space station, including urine and sweat,” NASA astronaut Jessica Meir said in a statement. “What we try to do aboard the space station is mimic elements of Earth’s natural water cycle to reclaim water from the air. And when it comes to our urine on ISS, today’s coffee is tomorrow’s coffee!”
So yes, the astronauts do drink their own urine.
This urine recycling process decreases the need to launch a supply of water to space, particularly on longer, roundtrip flights to and from Mars, which could take up to two years. NASA aims to recycle at least 98 percent of urine before the planned trip to the Red Planet.
