NASA is preparing to ignite the first controlled fire on the Moon as part of a first-of-its-kind experiment designed to improve astronaut safety during future lunar missions.
The experiment, known as Flammability of Materials on the Moon (FM2), will study how fire behaves in the Moon’s one-sixth gravity, where scientists believe some materials considered safe on Earth could burn more easily.
Researchers say the findings could help shape safety standards for future Artemis missions and long-term lunar habitats, where astronauts may not be able to quickly escape in the event of a fire.
Why NASA Is Studying Fire on the Moon
NASA has spent decades studying combustion in microgravity aboard spacecraft, including controlled flame experiments inside Northrop Grumman Cygnus cargo vehicles.
Current material safety standards rely on testing conducted under Earth’s gravity. One of NASA’s primary certification methods, known as NASA-STD-6001B, exposes materials to a six-inch flame. Materials fail the test if flames spread beyond six inches or produce burning debris.
Scientists say those Earth-based tests may not accurately predict how materials behave in the Moon’s reduced gravity.
According to NASA researchers, previous experiments conducted aboard the International Space Station, parabolic aircraft flights, and drop towers suggest some materials could ignite at lower oxygen concentrations in partial-gravity environments than they do on Earth.
Reduced Gravity May Increase Fire Risk
On Earth, hot gases rise quickly, drawing fresh oxygen into a flame. In some cases, the airflow becomes fast enough to extinguish the fire through a process known as “blowoff.”
On the Moon, weaker airflow may allow chemical reactions within a flame to continue more efficiently, potentially making certain materials easier to ignite and allowing fires to spread differently.
Researchers also noted that future astronauts are expected to live in habitats with lower atmospheric pressure and higher oxygen concentrations, conditions that could further increase the risk of fire.
NASA said understanding these hazards is essential because fires inside spacecraft or lunar habitats could be catastrophic.
First Combustion Experiment on Another World
The FM2 mission will become the first combustion experiment ever conducted on the surface of another planetary body.
The autonomous experiment will burn four solid fuel samples individually inside a sealed chamber designed to simulate the atmospheric conditions planned for future lunar habitats and spacecraft.
Cameras will record flame size, color, intensity and spread rate, while onboard instruments monitor oxygen levels, carbon dioxide, flame temperatures and fuel temperatures.
The hardware measures approximately 28.5 by 28.5 by 38.5 centimeters and weighs about 25 kilograms.
NASA said the experiment is currently targeting a launch in late 2026.
Supporting Future Artemis Missions
Researchers said FM2 is intended to bridge the gap between laboratory testing on Earth and real-world conditions astronauts will encounter on the Moon.
“The tests will provide benchmark data and are part of the larger effort to understand how lunar gravity will affect material flammability,” the research team said, Futurism reported.
The results could lead NASA to revise its material certification standards for spacecraft, habitats, and even spacesuits used during future Artemis missions and eventual human exploration of Mars.
Scientists say establishing how fire behaves in lunar gravity is a critical step toward safely maintaining a permanent human presence beyond Earth.
