Overview
- NASA scientists detailed the Flammability of Materials on the Moon proposal at a recent planetary science conference, with media reports tracing the plan to a document spotted by Universe Today.
- FM2 would ignite four solid samples inside small sealed chambers that mimic a livable atmosphere, with cameras, radiometers, and an oxygen sensor tracking flame behavior.
- The team wants to test whether NASA’s Earth-based flammability rule, NASA-STD-6001B, holds in one-sixth gravity, warning that materials safe in 1g may ignite when blowoff is weaker on the Moon.
- Earlier work in drop towers, sounding rockets, and the Cygnus Saffire experiments showed flames burn differently off Earth, including spherical shapes and shifts in flammability limits, but none captured sustained lunar-gravity data.
- Researchers describe a target launch in late 2026 via a commercial lunar lander as a proposal that still needs approvals, and they say results could guide habitat atmospheres, material choices, and emergency procedures for future crews.
