Burning fuel in zero gravity looks nothing like it does on Earth. 🔥 Here, hot air rises and cool air sinks — that’s what gives a flame its classic teardrop shape. But in space, there’s no “up” or “down.” No gravity means no convection currents. So, instead of flickering upward, the flame forms a perfect glowing sphere, burning slowly and evenly in all directions. A quiet fire, floating in the dark. 🚀 - #spacefacts #science #nasa #zerogravity #physics | How History Is Created

Microgravity on Earth‪? 🌎 No problem. We make it happen in our Zero-Gravity Facility. Here, we investigate weightlessness and study its effect on fluids, materials & combustion.
