‘Space Plumber’ saves the mission: Astronaut Christina Koch repairs $23M Artemis II toilet mid-flight
(BREAKING: Artemis II toilet problem has been resolved & is now “go for use”)
Somewhere between Earth and the Moon, NASA astronaut Christina Koch picked up an unexpected side gig: “space plumber.”
Koch, a veteran astronaut and mission specialist aboard NASA’s Artemis II, earned the tongue-in-cheek title after successfully troubleshooting a malfunction in Orion’s $23 million onboard toilet—arguably the most critical system no one wants to talk about, until it breaks.
“I’m proud to call myself the space plumber,” Koch said with a smile during a post-fix update, underscoring both the humor and the high stakes of the situation.

Who Is Christina Koch—and Why She Grabbed the Wrench (Metaphorically and Literally)?
Koch, a Michigan-born electrical engineer and seasoned NASA astronaut, is no stranger to high-pressure situations. She previously set records for one of the longest single spaceflights by a woman and has participated in historic spacewalks. On Artemis II, she joins Commander Reid Wiseman, Pilot Victor Glover, and Canadian astronaut Jeremy Hansen on humanity’s long-awaited return to deep space.
But even the most elite crews can’t escape the occasional plumbing problem.
Shortly after launch on April 1, a fan/controller issue knocked out the Orion spacecraft’s Universal Waste Management System—the first toilet of its kind designed for a lunar flyby. For several uncomfortable hours, astronauts were forced to “hold it” or rely on backup collection bags while Koch, guided by Mission Control, got to work.
The culprit? A system that had been sitting too long and needed time to warm up and properly prime—less catastrophic failure, more stubborn morning coffee machine.
After removing components, running diagnostics, and, yes, essentially turning it off and back on again, Koch and the team restored full functionality. Relief—literal and otherwise—quickly followed.
A High-Tech Toilet With a Critical Mission: The Orion toilet isn’t just a convenience—it’s essential for crew health and mission safety. In microgravity, it uses air suction instead of gravity to manage waste, venting liquids into space and storing solids for return to Earth. It’s also a significant upgrade from the Apollo era, when astronauts had to rely on bags—with occasionally messy and infamous results.
As Hansen joked in earlier mission footage, it’s also the only place astronauts can get a moment of privacy—making its swift repair all the more appreciated.
Artemis II: A Giant Leap (With Fully Functional Plumbing): Toilet troubles aside, Artemis II is making history. The mission marks the first time since Apollo 17 in 1972 that humans have left low Earth orbit.
After a successful translunar injection burn, the Orion spacecraft—named Integrity—is now on course for a lunar flyby. The 10-day mission will send the crew around the Moon without landing, testing critical systems and paving the way for future lunar landings and eventual missions to Mars.
NASA reports that all major systems are now operating smoothly, and the crew has already begun capturing stunning images of Earth and preparing for upcoming milestones.
What’s Next? The Artemis II crew is set to perform a close flyby of the Moon on April 6, capturing high-resolution imagery of the lunar surface—including rarely seen views of the far side—before beginning their journey home.
If all goes according to plan (and the plumbing holds), the mission will conclude with a splashdown in the Pacific Ocean off the coast of San Diego.
For now, Artemis II continues its journey with one less problem—and one newly certified “space plumber” keeping things flowing smoothly. (And I cannot get Steve Miller’s iconic hit song “I’m A Space Cowboy” out of my head.)
