Astronauts aboard NASA’s Artemis II mission encountered a technical issue with their spacecraft toilet just hours after launch, forcing them to rely on backup systems until the problem was resolved.
Mission specialist Christina Koch first reported the issue to mission control after noticing a blinking fault light during the early phase of the 10-day mission. NASA officials later confirmed that the malfunction was linked to a controller problem affecting the toilet system.
Norm Knight, NASA’s director of flight operations, said the issue disrupted the urine collection function, while NASA spokesperson Gary Jordan explained during live mission commentary that a fan within the system had become jammed.

The malfunction temporarily disabled part of the Orion spacecraft’s waste management system, requiring the crew to use a backup method. However, NASA said the system for handling solid waste remained operational.
After several hours, engineers were able to resolve the issue, allowing the astronauts to resume normal use of the onboard toilet. The Artemis II mission marks a significant step in NASA’s return to lunar exploration and is the first crewed mission to fly past the Moon since the Apollo era.
Unlike earlier missions in the 1960s and 1970s, where astronauts relied on basic waste collection bags, the Orion spacecraft is equipped with a modern toilet system known as the Universal Waste Management System.
The system includes a hose and funnel mechanism for liquid waste, which is vented into space, as well as a storage container for solid waste, which will be disposed of upon the crew’s return to Earth.
