Dear Terrestial Fire Engineers, let me take you on a journey that will make you experience fire engineering like nothing on our planet. Because in fact, it is the fire engineering of spacecraft for their operations in a zero-gravity environment. The environment in which the most fundamental aspects of fire engineering (think about smoke cannot go up when there is no up!) are being challenged. Where fire physics is completely different, and where things that are necessary for humans (oxygen, clothes...) become a major risk factor.From my today's guest, Dr David L. Urban of NASA Glenn Research Centre, we will learn about the catastrophical fires that shaped the space industry. We get introduced to testing methods and fire safety engineering solutions commonly used on older and modern spaceships, and also try to take on the issue of fire safety of beyond-Earth human habitats.I'm not sure how much practical engineering you will learn, but I am more than sure that you will enjoy this thoroughly. And maybe one day, you can pursue a career in space fire engineering...Who knows!Additional resources:Saffire project25 Years Ago: Fire Aboard Space Station MirBBC 13 minutes to the moon - episode 4 (Apollo 1 fire)Cover picture credit: NASA Glenn Research Centrehttps://www.nasa.gov/feature/studying-flame-behavior-in-microgravity-with-a-solid-high-five
