Each year, thousands of wildfires release large amounts of planet-warming carbon dioxide into the atmosphere and burn roughly 1.5 million acres of forests and grasslands throughout the country, according to the U.S. Forest Service. Suppressing these blazes is a complex and costly operation – with suppression costs averaging $2.9 billion over a five-year period. Containing and responding to these fires also requires collaboration among firefighters and ground crews, and the coordination of dozens of aircraft operated by multiple government agencies.
NASA’s Advanced Capabilities for Emergency
Response Operations (ACERO) project - led by the agency’s Ames Research Center
in Silicon Valley, California - is using drones and advanced aviation
technologies to improve wildland fire coordination and operations.
Current aerial firefighting operations are
limited to times when aircraft have clear visibility – otherwise, pilots run
the risk of flying into terrain or colliding with other aircraft. That means
aircraft are grounded during the night and during periods of heavy smoke.
Drones can help expand the window of time available for aerial suppression
because they can be safely operated by pilots on the ground. Using drones for
aerial suppression operations would reduce safety risks to pilots and make
aerial wildfire operations more effective.
Though drones and other aviation
technologies have rapidly advanced over the last decade, emergency responders
have been slow to adopt them. One significant barrier that continues to prevent
this adoption is lack of tools and situational awareness for responders to see
where firefighting drones are operating. To address this issue, ACERO is
developing airspace management technologies to share information between crewed
aircraft, drone operators, and ground crews during wildfire responses. These
technologies will provide all responders with common situational awareness and
ensure there are no conflicts with aircraft operations. ACERO-developed
aircraft safety software will also reduce the likelihood of encountering
airborne hazards. Having this situational awareness will enable responders to
safely integrate drones into wildfire operations and continuously suppress and
monitor a fire over its entire lifetime, which is not currently possible.
ACERO's advancements in aerial
communication and information-sharing tools and concepts will improve airspace
management during wildland fires and provide response crews more timely
information to support decision-making during emergency response. These
advancements are critical for enabling new drone missions for aerial wildfire
response, like fire suppression, delivering gear to ground crews, and providing
communication relays in areas with limited connectivity.
Drones could also be used for prescribed
burns, or fires set and controlled by experts designed to burn away the dead
brush that acts as fuels and can lead to large-scale wildland fires. Currently,
these types of burns are set by a combination of piloted helicopters, ground
grew, and a very limited amount of drones. Remotely operating drones for these
operations would be safer and cheaper than deploying ground crews and
helicopters. It would also enable crews to execute controlled burns over larger
acreages of land each year.
Yasmin Arbab, a research associate at NASA’s Ames Research Center, tests a prototype device designed for firefighting drone operators, while piloted aircraft perform fire training operations in the sky, in Redding, California, on May 3, 2022. Intended to help scale up the use of unmanned aircraft systems (UAS) – or drones – in disaster response, the UAS pilot’s kit (UASP-kit) was developed by NASA’s Scalable Traffic Management for Emergency Response Operations (STEReO) project.

The Future of Wildland Fire
Response
ACERO is collaborating with other
government agencies, the science community, and commercial industries to
develop a concept of operations for the future of wildland fire management. The
project’s team leads an interagency working group to assess and identify the
concepts and technologies needed to address the challenges ahead. ACERO will
work with other government agencies to help integrate these technologies into
wildland fire operations.
In the coming years, NASA will
partner with industry and wildfire response agencies to perform joint field
demonstrations of newly developed ACERO-led aviation technologies. These
demonstrations will highlight developments from the agency’s Aeronautics
Research Mission Directorate, Science Mission Directorate, and Space Technology
Mission Directorate.
ACERO builds on previous NASA Aeronautics research including Scalable Traffic Management for Emergency Response Operations project and the Unmanned Aircraft System Traffic Management project. ACERO’s aviation advancements for wildland fire operations support NASA’s contributions to the U.S. goal of reaching net zero aviation greenhouse gas emissions by 2050. The project also supports the NASA’s Advanced Air Mobility research, which will guide industry's development of electric air taxis and drones and assist the Federal Aviation Administration in safely integrating such vehicles into the national airspace.
ACERO is funded by NASA’s
Aeronautics Research Mission Directorate, managed by the agency’s Airspace
Operations and Safety Program.
