Artemis 2's Space Toilet Hits a Snag, NASA Investigates UWMS Blockage

Artemis 2’s Universal Waste Management System on the Orion spacecraft is showing multiple toilet problems, including a jammed urine-collection fan, a burning odor, and difficulty venting stored urine. NASA says the system remains usable but relies on contingency urine bags while engineers search for a root cause—currently suspected to be debris clogging a filter rather than icing—before Orion returns for full analysis after splashdown. The hiccups, while inconvenient, are a critical debugging step for refining the waste-management system for future Moon and Mars missions.
