Agnirva Space Premier League - Expedition #31143: Breathing Easy in Space: JEM CO2 Removal System

Keeping the air breathable on a spacecraft is no small task. That’s why the 'JEM Demonstration of CO₂ Removal System' is such a big deal. Developed by JAXA and tested aboard the International Space Station during Expeditions 73 and 74, this experiment focused on evaluating a new system for removing carbon dioxide from cabin air.

Why is CO₂ removal important? In the closed environment of a space station, CO₂ exhaled by astronauts accumulates quickly. If not removed efficiently, it can lead to headaches, fatigue, and more serious health issues. This project aimed to improve upon existing systems by creating a more compact, energy-efficient, and effective technology.

The new system was tested in Japan’s Kibo module (JEM) and involved innovative filtering materials and airflow management strategies. Researchers measured the system’s efficiency in real-time and evaluated its durability over extended periods.

Beyond immediate use on the ISS, this tech has applications for future long-duration missions to the Moon or Mars. As we plan for space habitats far from Earth, sustainable life support systems like this one become critical.

The experiment also supports research into closed-loop environmental systems, which could benefit future Earth-based technologies for submarines, disaster shelters, and even eco-friendly buildings.
