Key Question

Background

The Contingency Collapsible Urinals (CCUs) became the Artemis II crew’s primary waste solution on the morning of Day 4 after a suspected ICE blockage seized the Orion spacecraft’s wastewater vent system. Flight controllers reoriented the spacecraft to let sunlight thaw the pipe; the crew reverted to CCUs until the line cleared by early afternoon on 4 April 2026.

CCUs are disposable, folding funnel-and-bag devices carried on crewed spacecraft as a backup to the primary Waste Collection System. They do not require power or plumbing and can be sealed and stowed. A predecessor device was used on the Space Shuttle during emergency situations. The Orion WCS has now experienced three distinct anomalies in five days: a fan failure, a separate vent fault, and the ICE blockage that triggered CCU use.

The recurrence of Orion toilet faults highlights a design constraint in long-duration crewed capsules: waste management on a week-long mission profile is significantly harder to make reliable than on an orbital station with sustained maintenance access.

Common Questions
Why did the Artemis II toilet break?

How many times did the Artemis II toilet fail?
Three distinct anomalies occurred in the first five days: a fan failure, a separate vent fault, and an ICE blockage in the wastewater vent that required CCU backup use.Source:
