Forget the Moonwalk. The real excitement for the crew aboard NASA’s Artemis II might just be a few minutes of privacy on the throne. After decades of astronauts dealing with diapers and plastic bags in microgravity, Orion— the deep-space crew capsule—now comes equipped with a fully functional space toilet designed to handle both liquid and solid waste in weightlessness. For a 10-day journey around the Moon, that’s nothing short of revolutionary.
A Giant Leap For… Bathroom Breaks
The toilet uses airflow instead of gravity to direct waste. Each astronaut has their own urine funnel, and solid waste is deposited into bags that are stored in a “poop filing cabinet” until the crew returns to Earth for proper disposal. Handles and straps help astronauts stay stationary in microgravity
while using the toilet, ensuring safety and hygiene.
The system is adapted from the International Space Station’s Universal Waste Management system, but simplified for Artemis II’s 10-day lunar flyby mission. A door and privacy options have been added, making it the first time that astronauts on a lunar mission have had actual privacy while using the bathroom.

If the system fails, astronauts have contingency gear that reverts them back to the Apollo-style poop bags, ensuring no mission is ever without a backup plan. “This isn’t just a convenience upgrade; it’s an essential system we have to get right if humans are going to live and work away from Earth for longer periods,” the NASA engineer told Space.com.
Life In Space
The Artemis II crew, including NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian Space Agency astronaut Jeremy Hansen, will be the first humans in more than 50 years to travel beyond low Earth orbit. The new toilet will allow them to spend time focusing on science, navigation, and observation, without worrying about microgravity mishaps.
Astronauts and NASA staff alike have joked about the “luxury” of a private moment in space. A mission insider told the New York Post: “It’s funny to think people are excited about a bathroom, but honestly, it’s huge—alone time in orbit is priceless.”
More Than Comfort
According to NASA, the toilet is not just about comfort. In zero gravity, conventional plumbing doesn’t work, and airflow is required to direct waste safely. The UWMS builds on technology from the International Space Station but has been modified for the smaller Orion capsule and the longer, deep-space trip around the Moon, Starlust reported.

NASA engineers highlight that solving the “toilet problem” is a small but crucial step toward sustainable long-duration space missions.
“The humble space toilet may not make headlines like rockets or moon landings, but it’s symbolic,” an official told Sky at Night Mgazine. “If humans are going to thrive in space, even the most mundane aspects of life have to be figured out.”
