The crew of the Artemis II mission is currently pushing deeper into space than any human in history, but their historic journey has been accompanied by a decidedly earthly problem: the Orion capsule toilet acts up again as astronauts speed towards the moon.
More than halfway to their destination, the four-person crew is preparing for a lunar fly-around that will take them beyond the distance reached by the Apollo astronauts. While the views are breathtaking, the “lunar loo” has been hit-and-miss since shortly after Wednesday’s lift-off, forcing the crew to rely on backup systems for waste management.
The mission includes three Americans and one Canadian, marking the first crewed attempt to reach the moon in over 53 years. Pilot Victor Glover described the evolving perspective of the journey, noting, “The Earth is quite small, and the moon is definitely getting bigger.”
Despite the technical glitch in the bathroom, NASA officials emphasize that the mission remains on track. The crew is scheduled to reach the moon on Monday, where they will photograph the lunar far side before beginning their return trip to Earth.
The Mechanics of a Lunar Malfunction
The Universal Waste Management System on the NASA Orion spacecraft is a complex piece of engineering designed to operate in microgravity. For solid waste, astronauts use a specialized seat that vacuums stools into a smell-free container. Urine is handled via a personal funnel and a fan system that draws liquid into a tank before We see jettisoned into the vacuum of space.
However, this system has not performed perfectly. Engineers suspect that ice may be blocking the line, which prevents urine from flushing completely overboard. This blockage has led to reports of an unpleasant smell emanating from the bathroom, which is tucked into the floor of the capsule and shielded by a door and curtain for privacy.
As a temporary workaround, Mission Control has instructed the crew to utilize backup urine collection bags. This is a known contingency; the astronauts were specifically trained to manage such a scenario during their preparation for the mission.
A History of Space Plumbing Challenges
While the current situation is inconvenient, NASA officials note that bathroom issues are a recurring theme in human spaceflight. Debbie Korth, Orion program deputy manager, pointed out that space toilets are a universal challenge and mentioned that the space shuttle’s facilities were also frequently problematic.
The development of the Orion system was an intensive process, with a version of the toilet tested on the International Space Station several years ago to iron out bugs before the lunar mission. Despite these efforts, the harsh conditions of deep space—including extreme temperature fluctuations—continue to test the limits of the hardware.
John Honeycutt, chair of the mission management team, acknowledged the public’s fascination with the “space commode,” stating that while the system is currently in a “good state,” the goal is always 100 percent functionality.
The Broader Stakes of Artemis II
While the toilet malfunction is a point of operational friction, the mission’s overarching goals remain historic. The crew—consisting of Reid Wiseman, Jeremy Hansen, Christina Koch, and Victor Glover—is set to travel more than 400,000 kilometers from Earth. This will set a new distance record for human spaceflight, surpassing the mark previously held by the crew of Apollo 13.
The mission is also a milestone for diversity and international cooperation. Christina Koch and Victor Glover are the first woman and first Black astronaut to travel to the moon, respectively. Jeremy Hansen is the first non-U.S. Citizen to fly to the moon, a feat celebrated by the Canadian Space Agency in Quebec.
This fly-around is the critical first step toward NASA’s long-term goal of establishing a sustainable lunar presence. The agency is currently targeting a mission to land two astronauts near the lunar south pole in 2028.
Mission Timeline and Key Milestones
| Event | Timeline/Detail |
|---|---|
| Lift-off | Wednesday (Initial malfunction occurred) |
| Lunar Arrival | Monday (Scheduled fly-around) |
| Max Distance | >400,000 km (Record attempt) |
| Earth Return | Pacific Ocean splashdown on April 10 |
The crew’s journey will end with a splashdown in the Pacific Ocean on April 10. Until then, they will continue to transmit “extraordinary” views of the cosmos and provide vital data on how humans—and their plumbing—fare in the deep void of space.
The next major checkpoint for the mission will be the lunar fly-around on Monday, where NASA will monitor the capsule’s performance and the crew’s health as they navigate the far side of the moon.
