Overview
- NASA has confirmed the Flammability of Materials on the Moon (FM2) experiment will ignite four solid fuel samples one at a time inside a self-contained, sealed chamber equipped with cameras, an oxygen sensor and instruments that record temperature and radiation.
- The test will run autonomously on the lunar surface and record flame spread, heat output and gas use so engineers can see how fires start and move in about one-sixth of Earth’s gravity.
- Lunar gravity weakens the buoyant airflow that normally draws oxygen into Earth fires, which makes flames rounder, slower and able to burn some materials at lower oxygen levels than on Earth.
- The project is in pre-launch and operations preparation with hardware and safety plans publicly described, but final integration with a commercial lander and a launch schedule remain under development.
- Results could change how NASA certifies materials, designs habitats, and trains crews for fire emergencies, which may directly affect what materials and procedures astronauts use inside lunar bases.
