VANDENBERG SPACE FORCE BASE, Calif. -- Technicians from the U.S. Forest Service National Technology and Development Program conduct test burns using a fire front simulator system at Vandenberg Space Force Base, Calif., May 11, 2023. This cutting-edge system is controlled through a computer, which opens and closes fuel lines and ignites the burners in the simulator. It replicates the various stages of a wildfire, including the approach, immersion, and post-radiation phases.
