If all goes well, Artemis II It could be launched on April 1 towards the Moon. It will be the first time that a manned spacecraft travels to our satellite in more than 50 years and, although this time there will be no moon landing, the capsule with 4 astronauts on board will make a lunar flyby, which will be the highlight of a 10-day space trip. A week and a half during which, logically, the crew will have to clean up and relieve themselves. But how do you go to the bathroom in space? Luckily, the capsule will have a comfort that they didn’t have in the Apollo program. A toilet. The complicated mission of going to the bathroom. From Apollo 10, in 1969, until Apollo 17, in 1972there were a total of 12 astronauts who traveled to the Moon. At that time, her only toiletries were a few wet wipes. to urinate They used devices similar to condoms that were changed daily. When it was time to evacuate, they were connected to a bag, with a kind of hose. It was not a very efficient system and there were often leaks. There was also no system adapted to the female anatomy, since all the astronauts were men. The greater waters. As for feces, a bag was used that stuck to the buttocks. Something quite similar to a diaper, but with a compartment to put your hands in and use toilet paper. Again, there could be leaks. In fact, there is a transcript of an astronaut from Apollo 10 in which he asked for a napkin to pick up a fragment of feces that was floating in the air. Once caught (sometimes literally), the bags were saved and stored for analysis on land. Added to all this is that the astronauts did not have the slightest privacy to go to the bathroom in space. The experience, and especially the smell, could not have been pleasant at all. The urine collection system of the Apollo missions was very rudimentary. Opportunity cost. Whether it is for personal hygiene or for urinating or defecating, going to the bathroom in space involves two major complications. On the one hand, microgravity prevents what should fall under its own weight from doing so. We return to the problem of floating feces from Apollo 10. On the other hand, water is needed. Transporting sufficient quantities of water into space would place excess load on spacecraft. Furthermore, precisely because of microgravity, it would move freely, so that some of the many devices that exist in the small space of a capsule like the Orion of Artemis II could get wet and damaged. For this reason, the use of water is reduced to a minimum and methods are sought to overcome microgravity as much as possible. Artemis II’s toilet. In Artemis II the astronauts They will use liquid soap and leave-in shampooas well as very small amounts of water that can be dried immediately with towels. As for the most difficult part, the Orion capsule has a system similar to that used in the International Space Station. It is a container with a hose connected to a funnel through which urine descends thanks to an air suction system. Each astronaut will have their own hose and, since the crew has three men and one woman, it will adapt to both male and female anatomy, as necessary. Where does all that go?. Once the urine is collected, it is released into space. Regarding feces, they are also collected by suction and stored in sealed bags that will travel to Earth on the return trip. Best of all, this system is isolated, so astronauts can relieve themselves alone. There is a curtain that can be removed if they need more space and a door in the floor of the capsule that allows them the privacy they craved on the Apollo missions.
