As wildfire seasons intensify, NASA’s FireSense project has unveiled a new technology aimed at enhancing firefighter safety. The development of low-cost thermal sensors for fire bulldozers represents a significant advancement in the tools available to combat wildfires.
Innovative Sensor Technology
The sensors are designed to alert firefighters when the radiant heat from a nearby fire reaches dangerous levels. This innovation was demonstrated during a collaborative event with the Alabama Forestry Commission (AFC) in April 2026, where researchers and firefighters gathered to discuss advancements in firefighting technology.
“As we try to develop technologies that allow us to understand and respond to wildfires with our partners, ground observations are vital to provide context for what we are seeing from space,” stated Ian Brosnan, program manager for wildland fires at NASA’s Ames Research Center.
Integration and Testing
The AFC’s requirements for the sensors were straightforward: they needed to be low-cost and easy to operate. NASA utilized commercial, off-the-shelf components, including a thermocouple similar to those used in ovens, to measure temperature. When the sensor detects unsafe temperatures, it triggers a blinking LED light on the bulldozer’s dashboard, alerting the operator to move away from the fire line.
NASA installed the first sensor in September 2025, followed by a second installation in March 2026. Both sensors have since been tested on active wildfires and prescribed burns, proving effective in enhancing situational awareness for operators.
Future Collaborations and Data Collection
This initiative marks a milestone in the ongoing partnership between NASA and the AFC, which has included training sessions on weather and soil moisture, as well as testing airborne instruments on wildfires. Looking ahead, NASA plans to integrate the Fire Thermal InfraRed Spectrometer (FireTIRS) into the bulldozers. This instrument will measure critical parameters such as temperature, spread rate, flame length, and gas emissions.
Jennifer Fowler, science integration manager for the wildland fires program at NASA’s Langley Research Center, emphasized the importance of this data: “This is the dataset that will get us to the next generation of fire models. It gives us the detailed understanding we need to create tools that can give firefighters more advanced notice of what a fire will do.”
