Artemis II astronauts have toilet trouble on their way towards the Moon

NASA is preparing to send humans farther into space than ever before, but one system has faced challenges during the Artemis II mission. The four crew members aboard the Orion capsule have encountered sporadic issues with the spacecraft’s toilet since their launch on Wednesday. On Saturday, the toilet failed to expel waste, likely due to a frozen vent line, according to NASA. As a workaround, the astronauts have relied on collapsible plastic containers to collect urine, though the primary system remains in use.

Despite these setbacks, the mission has progressed into its fifth day of a 10-day journey around the Moon. The crew, including NASA’s Reid Wiseman, Victor Glover, and Christina Koch, along with Canadian Space Agency astronaut Jeremy Hansen, is confined to a compact cabin roughly the size of a camper van—5 meters wide and 3 meters high. During a Thursday video call with Earth, mission specialist Koch humorously noted a minor “priming” issue with the toilet, quipping, “I’m proud to call myself the space plumber. I like to say that it is probably the most important piece of equipment on board.”

“I think the fixation on the toilet is kind of human nature,” remarked John Honeycutt, chair of the Artemis II Mission Management Team, at a Saturday evening press conference. “Everybody knows how important that is to us here on Earth. And it’s harder to manage in space.”

NASA addressed the problem in a Saturday press release, explaining that a wastewater vent line had become obstructed. To resolve this, the crew adjusted the spacecraft’s orientation to direct the vent toward the Sun, which helped thaw the blockage. While the trajectory remained unaffected, the adjustment temporarily freed up space in the waste management tank. Engineers continue to employ vent heaters to melt ice, and the crew is advised to use backup collection devices overnight if necessary.

Artemis II is currently on a trajectory that will take the crew around the Moon’s far side and back, marking the first time since 1972 humans have ventured beyond Earth’s orbit. The four-person team will not land on the Moon but will orbit it, testing Orion’s capabilities for future missions. These trials include manual flight maneuvers in Earth’s orbit to evaluate steering systems and prepare for lunar landings. NASA Administrator Jared Isaacman highlighted the significance of the toilet issue during a Sunday CNN interview, stating, “We can do a lot of extraordinary things in space right now, but nailing this capability is one that we need to certainly work on.”

The mission’s success hinges on overcoming such logistical hurdles while demonstrating the reliability of the Orion spacecraft. With the toilet issue still under review, the crew remains focused on their objectives, ensuring the spacecraft’s systems are ready for the next phase of human space exploration.
