Agnirva Space Premier League - Expedition #32461: Keeping Astronauts Comfortable: Simulating Space Suit Undergarment Performance

Space is an extreme environment, and astronauts depend on specially designed suits to survive and work effectively. But what about comfort? That’s the focus of the CINCINNATI project—short for Comfort simulation of space suit underwear via draping and heat-management analysis.

Led by László Kovács of eCon Engineering Kft in Budapest, this experiment conducted on Expedition 73 investigated how fabric used in space suit undergarments behaves under real space conditions. The goal? To improve comfort, reduce fatigue, and enhance thermal regulation for astronauts on long-duration missions.

Using heat-management simulations and digital draping models, researchers assessed how different textiles manage moisture, temperature, and flexibility. These simulations help engineers refine garment design before physical prototypes are even made, saving time and resources.

Findings from the CINCINNATI project will guide the development of next-generation space suit layers that are not only protective but also more wearable—vital for missions to the Moon, Mars, and beyond.

Comfort may not be the first thing that comes to mind when thinking about space gear, but it’s essential for astronaut health and performance. This research blends technology and textiles in a uniquely space-age fashion.
