22 4 Full Breakdown

Summary

Story summary

NASA will launch the Flammability of Materials on the Moon (FM2) experiment to study flames in lunar gravity.
The Moon’s lower gravity reduces buoyancy, allowing flames to be fed by oxygen more continuously.
FM2 will burn four solid fuel samples inside a self-contained chamber equipped with sensors.
Earth-based tests like NASA-STD-6001B do not reflect space conditions.
