Artemis II crew copes with space toilet troubles using backup CCUs

Artemis II astronauts described how they handled toilet failures aboard the Orion during their lunar mission, relying on contingency collapsible urinals (CCUs) while engineers warmed a frozen vent to clear the clog. They used backup systems to stay hygienic, with each crew member carrying two CCUs, and even joked about the situation as they discussed showers and space hygiene during a town hall with children.
