A team led by NASA and U.S. Forest Service scientists recently collected real-time, visible and infrared data from sensors onboard a remotely piloted aircraft over the Esperanza Fire in Southern California.
The Esperanza Fire, an arson-set fire that claimed the lives of five firefighters, ignited on Thursday, Oct. 26, 2006. Whipped by powerful Santa Ana winds, it spread over 40,200 acres, or roughly 62 square miles, destroying 34 homes and 20 other structures.
The California Governor’s Office of Emergency Services and the Esperanza Fire Incident Command Center requested NASA’s imaging and fire mapping assistance. The Altair Unmanned Aircraft System, built and operated by General Atomics Aeronautical Systems Inc., San Diego, Calif., was prepared to fly in less than 24 hours. The flight was facilitated by the Federal Aviation Administration, which assures the safety of unmanned aircraft system flights in the National Airspace System. Recent changes to the FAA’s organizational structure allowed the approval to be expedited, while ensuring no degradation of safety and without imposing any new temporary flight restrictions.
From an altitude of 43,000 feet, the wildfire sensor collected and sent 100 images and more than 20 data files containing the location of the fire perimeter over a 16-hour period on Oct. 28 and 29, 2006. The data were delivered in real time through a satellite communications link. NASA and Forest Service specialists worked to familiarize the fire management team with accessing capabilities and sensor data format. The data from the NASA system were used by the Esperanza Fire Incident Command Center to map fire behavior and direct resources to critical areas on the fire.
The flight project was sponsored and funded by NASA’s Science Mission Directorate. The team consisted of specialists from NASA’s Ames Research Center, Moffett Field, Calif.; NASA’s Dryden Flight Research Center, Edwards, Calif.; the National Interagency Fire Center, Boise, Idaho.; U.S. Forest Service Remote Sensing Laboratory, Salt Lake City, Utah; California Governor’s Office of Emergency Services ; California Department of Forestry and Fire Protection, Sacramento, Calif.; and General Atomics Aeronautical Systems Inc.
NASA also shares the grief of the fire community in the loss of the true heroes of the Esperanza Fire, those that gave their lives in the battles against this disaster.
