The Artemis II crew contacted NASA mission control just hours after launch on Wednesday to report a problem with the spacecraft's toilet. The agency said the crew worked with ground teams to assess the data and successfully resolve the issue, avoiding the need to rely on a backup waste collection system.

Why it matters

The Artemis II mission is a critical step towards NASA's goal of returning humans to the lunar surface, so ensuring the spacecraft's systems are functioning properly is paramount. Resolving technical issues like this toilet problem demonstrates the agency's ability to quickly address challenges that arise during long-duration spaceflight.

The details

The crew reported a blinking fault light related to the toilet system prior to conducting an engine maneuver. Mission control teams worked with the astronauts to troubleshoot the 'controller issue' with the titanium toilet, which uses air suction to remove waste. NASA had a contingency plan in place involving a bag-based backup system, but the fix implemented by the ground and flight crews resolved the problem.

What they’re saying

“Mission control teams successfully assessed the data and worked with the crew to troubleshoot and resolve the issue.”

— NASA

“Had the fix not worked, NASA says it had a contingency plan in place: a bag-based backup system to collect urine for venting into space, with solid waste still collected in the capsule.”

— NASA

What’s next

The Artemis II mission is scheduled to circle the moon before returning to Earth, while the follow-on Artemis III mission in 2027 will test commercial landers for the first lunar landing since Apollo 17 in 1972.

The takeaway

This toilet issue highlights the importance of ensuring all systems on the Artemis spacecraft are functioning properly, as any technical problems could jeopardize the mission's success. NASA's ability to quickly troubleshoot and resolve the problem demonstrates the agency's preparedness for the challenges of long-duration spaceflight.
