NASA Creates High Tech Firefighting Tools
08.20.03
 

NASA is expanding the United States Forest Service's firefighting toolkit. New technologies provide better images faster and more often. This information allows firefighters to access wildfires more quickly and allocate precious resources. NASA hopes this new technology will help make the business of firefighting a little easier and safer.

This year, fires consumed over 2.3 million acres in the United States through August 21, 2003, the midpoint of the country's annual fire season.

Satellites Dial 9-1-1

Satellites sound the fire alarm on wildfires. New software, developed by NASA's Jet Propulsion Laboratory, Pasadena Calif., links several of NASA's Earth Science satellites together to form a virtual web of sensors with the ability to monitor the globe far better than just one satellite. An imaging instrument flying on one satellite can detect a fire or other hazard and automatically instruct a different satellite to take a closer look. If the images show that a potential hazard does exist, then the responding satellite provides data to ground controllers. They pass the data to the U.S. Forest Service, or to an interested science team.

Sensor Web DemonstrationImage to left: For the future, NASA is testing a semi-autonomous system, dubbed "sensor web," where various satellites will have an ability to communicate with each other, and provide interactive layers of images to ground users. In this way, one satellite might first detect a fire starting, and then signal another satellite to take a very detailed or specialized image of that fire for better monitoring.

This information allows firefighters to rapidly respond to ongoing events, such as fires, floods, and mudslides. Using sensor web technology means investigators now use nearer to real-time information on what's happening. More information-JPL

Better and Faster Communications

This image shows smoke plumes trailing from the fires, which were detected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite and are marked with red dots in the image.

Though yelling "Fire!" in a crowded theater may be prohibited, getting the message to firefighters about forest fires is essential. NASA teamed up with the U.S. Department of Agriculture's Forest Service to develop a digital wireless communication system that allows the real-time transmission of remotely sensed data from an airplane to a ground station. This quick relay of information about wildfires improves the likelihood that firefighters can handle the fire before it grows even more dangerous. More information-GSFC

Getting To The Heat Of The Fire

One of the latest , unmanned remote control airplanes fly over fires and broadcast thermal images to fire managers. Fire managers use these images to assess direction and speed. This new tool increases the efficiency of fire monitoring by speeding the access to information and imagery. More information-AMES
