Top of Mind with Julie Rose - Space Fire

Guest: Richard Axelbaum, Professor of Energy, Environmental & Chemical Engineering, Washington University in St. Louis

To make a fire, you need fuel, heat and oxygen. Since all three are easy to find on Earth, fire is common. But in space, there’s no oxygen, so no fire. Except on the International Space Station where astronauts are deliberately setting fires. Why? For science, of course.
