Astronaut Sophie Adenot of the European Space Agency shared footage of herself vacuuming the International Space Station’s ventilation grilles on Tuesday, highlighting routine maintenance that sustains air quality in the orbital laboratory. The cleaning operation, recorded during the station’s 3442nd orbit, supports the continuous recycling of air in a near‑closed‑loop system, a process comparable to that on submarines or climate‑controlled laboratories. Proper airflow is essential not only for crew comfort but also for the health of the station’s equipment and personnel. Adenot noted that daily tasks such as scientific experiments, physical exercise and housekeeping keep the station’s schedule full, with each crew member contributing to maintenance duties.
