About the project

AstroFlame Study Simulator is an interactive website that helps people explore how fire behaves in microgravity. It has been created for the NASA Space Apps Challenge to make NASA’s fire research easier to understand. Fire behaves differently in space, so understanding how oxygen and airflow affect flames is important for protecting astronauts. However, the research can be difficult to follow when it is spread across technical papers and datasets.

The project brings this research into a visual experience that users can explore for themselves. Users can choose a material, change oxygen and airflow settings, and select where ignition begins. A colored map shows the estimated spread of the fire, while a graph shows how the modeled flame front moves over time. NASA’s research has been used to inform these estimates and show the sources and assumptions behind them. The website combines an interactive interface with data processing to turn complex information into something easier to explore. AstroFlame is designed for students, researchers, and anyone curious about fire in space, with estimates meant for learning rather than real world safety decisions.
