In a refreshing take on the realities of spaceflight, Nasa astronaut Christina Koch, the first woman to travel to the Moon, has proudly embraced an unexpected title: “space plumber.”
Christina repaired the toilet onboard the Orion spacecraft hours after they were launched on a round trip to the Moon.
“I’m the space plumber, I’m proud to call myself the space plumber,” Koch said in a recent interaction, highlighting the often-overlooked technical responsibilities astronauts must undertake during missions.
Koch, who is part of Nasa’s ambitious Artemis II mission, emphasised that astronauts are trained to handle a wide range of tasks beyond piloting spacecraft or conducting scientific experiments.
Mission specialists, like her, undergo rigorous cross-training to ensure they can step into any role required during critical moments in space.
This includes maintaining and repairing essential onboard systems, even something as unglamorous, yet crucial, as the spacecraft’s toilet.
Space toilets are far from simple. In microgravity, waste management systems rely on suction, airflow, and precise engineering to function properly. Any malfunction can quickly escalate into a serious issue for crew safety and hygiene. That’s where astronauts like Koch step in, equipped with both technical expertise and adaptability.

Her comments shed light on the behind-the-scenes realities of human spaceflight, where problem-solving and versatility are just as important as exploration.
While the public often associates astronauts with groundbreaking discoveries and historic milestones, much of their work involves routine maintenance and troubleshooting in a high-stakes environment.
The four astronauts put the Orion on a course to the Moon by accurately nailing the Trans Lunar Injection.
Koch’s candid acknowledgement of her “space plumber” duties has resonated widely, offering a relatable and humanising glimpse into life aboard a spacecraft. It also shows the importance of teamwork and preparedness in missions that push the boundaries of human exploration.
As Nasa prepares for its return to the Moon under the Artemis program, astronauts like Koch represent a new era, one defined not only by historic firsts but also by humility, resilience, and a willingness to tackle every task, no matter how unconventional.
In space, even heroes sometimes have to fix the plumbing, and they do it with pride.
