The Space Station Is Getting a New Toilet
Eventually, the goal is to take the water out of astronaut poop and... uh... reuse it.
Astronauts on board the International Space Station will be about to sigh a big sigh of relief: the space station is getting a brand spanking new toilet, as Space.com reports.
The new system called the Universal Waste Management System (UWMS) is meant to be the (smelly) testing grounds for zero gravity toilets to be used during long space flight, such as a journey to Mars.
It’s also meant to standardize the toilet experience in space and thereby reduce costs — as well as lead to the development of smaller fecal canisters to improve stowage efficiency, according to NASA.
A NASA spokesperson told Space.com that the new and improved lavatory could be headed to the ISS as early as this fall, but a spacecraft has yet to be picked out for the special delivery.
The goal of the new toilet is also to make sure that we don’t have to leave human waste behind and thereby risking cross-contamination on distant planets. In fact, during Apollo 11, US astronauts left 96 bags of human poop on the lunar surface. Many scientists argue we should go back and dispose of it properly.
Long-distance space travel could end up accruing a lot of waste. In fact, NASA estimates that we’d need to manage about 600 pounds of solid waste on a mission to Mars.
“Our future goals are to stabilize and dry the metabolic waste to make it microbially inactive and possibly reuse that water, reduce the amount of consumables for the potty, because it does really accumulate on a long mission,” Jim Broyan, program manager for Environmental Control and Life Support Technology and Crew Health and Performance at NASA, said during a May 20 meeting, as quoted by Space.com.
The toilet on board the ISS right now dates back to the 90s. In the past, astronauts have struggled with aim. It also proved to be clunky to use, especially for women.
In February 2019, Russian media reported that the toilet on board the ISS burst, spilling gallons of fluid. The lucky astronauts had to mop it up with towels.
The new toilet will have an adjusted shape and will include toe bars for astronauts to hook their feet into. The same model will eventually fly on NASA’s Orion spacecraft that’s headed to the Moon later this decade.
