NASA to Conduct First-Ever Fire Experiment on the Moon

Washington D.C. – NASA is preparing to conduct a groundbreaking experiment, aiming to ignite a fire on the Moon for the first time in history. This mission, part of the "Flammability of Materials on the Moon" (FM2) experiment, is designed to study flame behavior in the Moon's unique gravitational environment.

The primary objective is to gather critical data for astronaut safety on future crewed missions, particularly for the Artemis program's voyages to Mars and beyond. Understanding how materials burn in space is essential, as some substances that are non-flammable on Earth could pose a fire hazard in different gravitational conditions and oxygen concentrations.

"Since fire can be a catastrophic hazard for spaceflight and extreme human exploration, FM2 is a critical step in determining material flammability and safety for future missions," NASA stated on the experiment's webpage. The agency notes that materials might burn at lower oxygen levels in lunar gravity, and burning materials could break off into fireballs in microgravity or partial gravity.

Flames exhibit distinct characteristics in space due to the absence of Earth's gravity-driven convection. While microgravity tests have been conducted on the International Space Station, resulting in rounded or spherical flames, lunar gravity (about one-sixth of Earth's) will produce slightly more rounded flames than on Earth. The experiment will involve a self-contained combustion chamber sent to the lunar surface, carrying four test samples made of cotton, fiberglass, and acrylic rods. Cameras and sensors will record the fire's spread and behavior.
