Artemis 2: NASA launches new services on the way to the moon

In the wee hours of the morning Israel time, one of the most intriguing missions of the American space agency in recent decades will begin, when four astronauts will take off on a journey around the moon in the new Orion spacecraft. Beyond the scientific and technological goals of the mission, one small detail preoccupies the public and the staff no less than the research achievements, and that is the issue of services in space. This is a dramatic improvement compared to the past, since during the Apollo missions, the astronauts had to face physiological challenges in extremely difficult conditions. In those days, defecation was carried out into plastic bags that were attached to the body, and urination was carried out using a rubber device that was connected to a tube, all while the rest of the crew were within touching distance and completely visible inside the small cell.

The location of the toilet door is on the floor of the capsule, an arrangement that seems strange on Earth, but in zero gravity conditions is completely natural. The astronauts simply float up to the door, open it, and walk in with ease. NASA calls this cabin the hygiene bay, and it also includes privacy curtains that can be used if additional space is needed. In that case, the astronauts can leave the door open and deploy the curtain to achieve the required separation from the rest of the living space. Although the cabin is very small, it provides the rare feeling of solitude that is so essential to the mental health of the crew during an extended stay in such a closed and stressful environment.

The system installed on Orion is very similar to the Universal Waste Management System in use on the US portion of the International Space Station. It includes a seat mounted above the collection tank and a long, flexible urine tube. Each of the staff members will have their own personal funnel that will be connected to the pipe, to maintain the highest level of hygiene possible and prevent cross infections. Since the Artemis 2 mission is relatively short, the system will not recycle the urine into drinking water as happens on the space station, but will eject the fluids into outer space several times each day. The ejection process is carefully timed so as not to interfere with the navigation systems or the scientific photographs of the lunar surface.

As far as solid waste is concerned, the process is a bit more complex and requires careful handling. The waste is pumped into a bag at the bottom of the container using a strong air flow that replaces the action of gravity that we are familiar with at home. During the mission, the astronauts will have to change the solid waste container several times, and all the contents will be returned to Earth with them at the end of the journey for research and hygienic tests. This will be the first time that this system has been tested in a manned flight outside low Earth orbit, since in the unmanned Artemis 1 mission, the equipment was not installed in the spacecraft and was not tested under real conditions.

In the meantime, NASA has also prepared for possible failure situations in the complex system. If the sophisticated system stops working for any reason, the crew is equipped with emergency equipment that includes manual urine collection bags, similar to the technology that was used 50 years ago. The engineers note that even if the services do not work fully, the astronauts will still be able to use the cabin as a physical space for defecating using the backup means. Knowing that there is an alternative solution provides additional security to the staff, although they very much hope they will not be forced to return to the old-fashioned methods of the past.

The transition to the use of modern and private services is not only a matter of physical comfort but also a matter of inclusion and modernization. The original Apollo missions involved only men, so engineers at the time did not have to design solutions that would suit both sexes equally. Today, when there are women in the team like Christina Cook, the need for a system that can serve everyone in an equal and respectful manner has become a threshold requirement that cannot be ignored. The new system has been carefully designed to fit the anatomy of all crew members and ensure they can perform their tasks without unnecessary distractions related to basic physical function.

Despite the high density in the Orion spacecraft, the ability to close a door and gain minimal privacy is considered one of the most significant improvements for the quality of life in space. The experts at NASA explain that the level of tension in a flight to the moon is enormous, and the possibility of disconnecting from the environment and colleagues for a few minutes a day is critical to maintaining concentration and high performance. With high chances of success and technology that supports the most basic human needs, the Artemis 2 mission is about to open a new era of deep space exploration. The engineers emphasize that even if this is a detail that seems insignificant compared to the powerful engines of a rocket The SSL, for the people inside the capsule, is the difference between a tolerable mission and a mission that allows one to maintain dignity and privacy.

90% of the preparations for the mission have already been completed and the crew is currently in medical quarantine before the historic jump. The toilet’s sophisticated system underwent a rigorous series of tests on the ground to ensure it would function properly in the extreme conditions of the journey. The astronauts have already practiced using the system in special simulators and they express satisfaction with the improved conditions.
