Artemis II's toilet is a moon mission milestone (scientificamerican.com)

Scientific American reports that NASA’s Artemis II will carry its first fully functional spacecraft toilet, the Universal Waste Management System, designed to work reliably in microgravity. Unlike Apollo’s bag-and-tube approach, the system includes a door, improved stability controls, and hardware that can handle urine and feces together while accommodating male and female astronauts. The technology has been tested on the International Space Station and is intended to inform future Artemis and Mars waste-management systems.
