NASA's Artemis II Mission Faces Recurring Toilet Malfunctions During Lunar Test Flight
The Artemis II crew encountered issues with the Orion capsule's Universal Waste Management System shortly after launch, requiring troubleshooting for pump priming and ice buildup in the vent. NASA resolved the problems by warming the vent with sunlight, restoring full toilet functionality. The mission, a 10-day test flight to the moon, continues without other major disruptions.

NASA's Artemis II mission, launched on a test flight to the moon, has proceeded without significant issues except for repeated malfunctions in the spacecraft's toilet system. The four-astronaut crew, aboard the Lockheed Martin-built Orion capsule, relies on the Universal Waste Management System (UWMS) for waste management during the 10-day journey.

The system, similar to the one used on the International Space Station, uses airflow to manage waste in microgravity.
The toilet issues began on the first flight day after the crew reached space. A problem with the pump, which required additional water to prime, caused the initial malfunction. Mission specialist Christina Koch, with assistance from Mission Control, resolved it by adding water to the system.
Despite the fix, the toilet malfunctioned again during wastewater dumps. Unlike the closed-loop recycling on the International Space Station, Orion's wastewater is ejected into space periodically. One dump halted prematurely due to suspected ice buildup blocking the vent nozzle, as observed in crew video showing particles streaming past the window.
To address safety concerns, NASA instructed the crew to halt urination use of the toilet while investigating the ice issue. Bowel movements remained permitted using water-tight bags. As a backup for urination, the crew employed Collapsible Contingency Urinals, tube-like devices designed for liquid collection in microgravity.
The urine collection tank in Orion has limited capacity, comparable to a small office trash can. Debbie Korth, NASA's Orion deputy program manager, noted during a news conference that timely emptying is essential to avoid overflow.
