NASA has been conducting experiments to understand how fire forms and spreads in space,media reported. They recently launched the Saffire IV experiment, in which the flames burn longer and the fires are stronger in Northrop Grumman’s “Swan” cargo ship. NASA wants to think about how the flame formed and spread in space to protect astronauts on trips to the moon and other parts of space.
Like other experiments in this series, Saffire VI was carried out on the ship after the Sathens cargo ship completed its main resupply mission and kept a safe distance from the International Space Station. But this experiment is significantly different from other experiments in the series. In Saffire VI, the researchers used a carbon dioxide scrubber and a cigarette swallower to remove particles and carbon monoxide from the environment after two material combustions.
Sensors and smoke filters that monitor burning gas are prototypes that the Orion spacecraft will use. NASA says it has additional diagnostic equipment for the Saffire VI mission to see how effectively it detects fires, measures combustion products and evaluates future fire response and cleanup techniques. In the experiment, the staff burned a sample of SIBAL cloth, which is believed to consist of 75 percent cotton and 25 percent of the fiberglass composite material.
As you can see in the video below, the bright spark left by the flame passing is the glowing coke on the surface of the cloth. The results showed that the flamespread spread rapidly, and the size and burning rate of the fire were stable, unlike the continued growth of the flames burning on Earth. The team also learned that the size of the spacecraft had a bigger impact on space fires than expected.
