Agnirva Space Premier League - Expedition #32208: Lighting Up Science: Exploring How Materials Ignite and Are Suppressed in Space

Imagine lighting a match in your room—simple enough, right? But what if that same match were in space, where gravity doesn’t act the same way? That’s the challenge researchers face when studying fire aboard the International Space Station (ISS). The "Solid Fuel Ignition and Extinction - Material Ignition and Suppression Test" (SFI-MIST) dives deep into the way different materials ignite, burn, and are extinguished in the unique environment of microgravity. This isn’t just about lighting fires—it’s about keeping astronauts safe and designing future spacecraft that can better resist fire.

Fire behaves differently in space. On Earth, hot air rises, creating the upward flow that shapes the familiar teardrop flame. But in microgravity, that buoyant force disappears. Flames become rounder, and smoke doesn’t rise. Instead, it surrounds the flame, potentially smothering it or changing its intensity. Understanding how these changes affect ignition is critical for both fire prevention and response.

SFI-MIST focuses on solid materials commonly used in spacecraft interiors—like fabrics, insulation, and composites. By exposing these materials to controlled heat sources, scientists examine when and how they ignite, how flames spread, and what conditions cause them to extinguish. The goal? Develop better fire suppression strategies and refine the safety guidelines for spacecraft construction.

This experiment is led by Dr. Carlos Fernandez-Pello from the University of California, Berkeley, in collaboration with NASA Glenn Research Center. It’s been tested during Expeditions 66, 70 through 73 on the ISS, offering a comprehensive look across different mission environments.

By understanding fire in space, scientists can not only build safer spacecraft but also uncover insights applicable to fire safety on Earth. The research contributes to materials science, combustion theory, and engineering, offering students an exciting glimpse into the intersection of physical science and real-world safety.
