Moon Spacecraft’s Toilet Fails Hours Into Ten-Day Journey

A controller fault jammed the UWMS fan on the Artemis 2 spacecraft hours into the mission.

The crew used a collapsible contingency urinal and backup urine system while fecal function was offline.

Mission control guided the crew through a fix and the UWMS was restored hours later.

The UWMS uses a urine funnel and air-suction bag-lined seat, but fecal waste is still bagged for return to Earth.
