Hours before the historic moments in NASA's manned return trip to the Moon, the agenda of the Artemis 2 team was determined this time by the toilet malfunction on the spacecraft Orion. While the crew moved towards the Moon, they also dealt with bad smells, urine drainage problems and temporary solutions. Although the mission team said there was no dangerous situation, the incident once again showed that the most critical details in space travel can sometimes come from the most unexpected places.
The Artemis 2 mission is preparing to make space history as it will again fly a manned crew near the Moon after more than 53 years. However, the most talked about topic of the last days of this historic flight was not the astronauts' scientific experiments or route maneuvers, but the toilet system in the Orion capsule.
It was revealed that there were problems with the hygiene system from the first day of duty. First, it was announced that the urine collection function of the toilet was disabled, and then mission specialist Christina Koch fixed the problem together with Ground Control. While Koch humorously described himself as a "space plumber" in his live connection, he said that this system is one of the most important equipment on the ship.
HE GIVEN AN ODOR ALARM
The problem was not limited to just that. In the days that followed, the crew reported an unusual "burning odor" coming from Orion's small hygiene compartment. It was stated that the smell was similar to the smell of an electric heater that has not been used for a long time when it is first turned on.
NASA launched an investigation to find the source of this smell. Initial evaluations indicate that the situation may not be caused by an electrical issue, but rather by a mechanical reason, such as the release of gas by some tapes and materials. Authorities state that, based on the available data, they do not see any signs of a dangerous or toxic environment.

Of course, although the phrase "not dangerous" is comforting in such a mission, even the burning smell coming from a tiny compartment is a cause of stress for a crew of four on the way to the Moon. Because even the simplest systems in deep space flights can directly affect life comfort and mission flow.
URINE DISCHARGE ALSO STOPPED
One of the real problems occurred in the process of evacuating the urine stored by the toilet into space. The system reportedly stopped after draining only 3 percent of the liquid in the tank. Flight control teams evaluated that the reason for this might be a blockage caused by icing that could occur in the extreme cold of space.
Thereupon, the Orion capsule was positioned to point the urine discharge nozzle towards the Sun for hours. The aim was to warm the system, dissolve any possible icing and allow the evacuation to restart. This “warming up” maneuver partially worked; It was announced that approximately half of the tank could be emptied.
However, despite this, the crew was not immediately allowed to use the toilet normally. In Christina Koch's radio conversation to Ground Control, "Can we find out when we can use the restroom again?" His question revealed the extent of the problem. After Koch, he jokingly said, "Can you let me use it once?" His statement showed that he tried to maintain the morale of the astronauts even during the most serious moments of the mission.
TEMPORARY SOLUTION HAS BEEN ACTIVE
While the toilet could not be used at full capacity, the team had to make do with a temporary device. This emergency solution for the crew's "number one" need works like a cylindrical plastic container. Then the liquid inside is transferred to the tank. It was stated that each astronaut was given two of these devices.
According to the information shared by NASA astronaut Don Pettit, this system offers a practical backup solution that does not require the use of diapers in such a situation. Here it becomes clear why toilet systems are considered so important in space missions. Because in a closed, narrow and resource-limited capsule, hygiene means not only comfort but also operational sustainability.
The toilet on Orion was designed as a smaller and more compact version of the systems on the International Space Station. Millions of dollars have been invested over the years in the development of this small hygiene compartment integrated into the base of the capsule. Despite this, such disruptions in real flight conditions remind us of how complex Moon missions still are.
