The Artemis II crew and mission control in Houston worked with speed to restore Orion’s toilet to normal operations after a fault light appeared ahead of the apogee raise burn on April 1. The issue surfaced early in the mission, when the crew was already focused on the next steps in orbit around Earth. NASA said the system was later cleared for continued use.
What happened on Artemis II
The first problem began within hours of launch on April 1, when part of the urine collection system failed to function properly. The issue was traced to the system not being fully primed with water, and once that was corrected, it began working again.
A few days into the mission, flight controllers identified another problem involving waste disposal, with signs pointing to frozen urine in the vent line. The spacecraft was repositioned so sunlight could warm the affected area, allowing the system to clear. Around the same time, the toilet was only cleared for limited use, which became a point of attention outside the mission control room.
NASA said the crew, working closely with mission control in Houston, was able to restore the Orion spacecraft’s toilet to normal operations following the proximity operations demonstration. The agency also said the crew reported a blinking fault light before the apogee raise burn, and teams successfully assessed the data and worked with the crew to troubleshoot and resolve the issue.
Speed in the response
That response mattered because Orion’s toilet is one of the most important onboard systems for astronauts. The crew also reported an unusual smell coming from the hygiene bay. Christina Koch, astronaut on Artemis II, described it as “a kind of burning heater smell, ” though its exact source was never fully confirmed.
Mission control later noted there were no major concerns and cleared the system for continued use. The update came as the crew prepared for a four-hour nap and a wake-up time of 7 a. m. EDT on Thursday, April 2, before the perigee raise burn.
NASA Speed and the next steps
The perigee raise burn will lift the lowest point of Orion’s orbit around Earth. Together with the earlier apogee raise burn, the maneuvers shape the spacecraft’s initial orbit and prepare it for later translunar operations.
Even with the fixes in place, the updates quickly drew attention beyond the space community. The mission’s pace, and the speed of the troubleshooting, turned a routine hardware problem into a brief but memorable moment in the early Artemis II flight. For now, the system is working, the crew is resting, and the next orbital burn remains the immediate focus as Artemis II continues.
