NASA Glenn’s Zero Gravity Research Facility performed its 100th microgravity drop test in fiscal year 2025 on July 23! 🔥 During the test (shown in this high-speed video), a single droplet of blended methanol and ammonia fuel was placed into a hot, high-pressure chamber and ignited. Burning fuel in simulated microgravity makes it easier to recreate and study the flame’s behavior in computer simulations. This research explores how the fuel droplets ignite and burn to identify possible options for
