NASA has announced plans to light a fire on the lunar surface in a first-of-its-kind experiment aimed at boosting astronaut safety.
After achieving a record-breaking 10-day lunar flight, NASA is planning to send astronauts to the Moon under its Artemis IV mission scheduled for 2028.
At the Lunar and Planetary Science Conference, researchers unveiled a new project called “Flammability of Materials on the Moon,” which explores how fire will behave in the Moon’s unique gravitational environment. This project will provide a unique insight into fire safety while on future deep space missions.
On Earth, flames behave differently, taking on a teardrop shape as cold air sinks in the presence of gravity. Microgravity, on the other hand, produces a more circular flame, which changes the way the fire spreads.
According to preliminary numerical models, the conditions present on the Moon would turn fire into something more dangerous than zero-gravity.
According to the researchers’ observations, flame spread rates may actually peak in partial gravity environments (such as on the Moon or Mars) rather than in the full gravity of Earth or the weightlessness of the ISS. Ultimately, this behavior will pose a challenge to the design of future habitats and astronaut safety gear.
If the recent experiment proves successful, Mission Artemis will be a breakthrough in improving safety measures for astronauts. However, rigorous testing is impossible without a continued human presence on the lunar surface.
