An interesting discussion of combustion research in microgravity:

Public Affairs Officer Lori Meggs at Marshall Space Flight Center in Huntsville, Alabama talks about a “cool” flames experiment in space. Meggs speaks to Vedha Nayagam, co-investigator for the FLEX-2 combustion experiment.

You never want to hear about a fire in space, but for this experiment, that’s exactly what had to happen. The FLEX-2 experiment burned different types of fuel droplets and showed us how flames behave without gravity, so that we may learn better ways to extinguish flames in space — information that could lead to improved environmentally friendly fuels on Earth.
