This NASA Flight Opportunities Community of Practice Webinar will explore the unique aspects of testing a suite of Earth observation sensors as well as how these technologies might be leveraged for planetary exploration. On April 23, 2025, a payload comprising three technologies designed to autonomously detect wildland fires from the stratosphere flew aboard an Aerostar International high-altitude balloon for eight hours over several contained and controlled burns.

Designed to fuse the observations of multiple sensors simultaneously, the payload combined:

• A sensor developed by Harvard University that measures the quantity of smoke by particle size
• The Xiomas-developed multi-band thermal imager called TBIRD (Three Band Infrared Detector) that quantifies burning intensity and estimates the fire’s smoke-producing emissions
• The ASI (Atmospheric Structure Investigation) from NASA’s Ames Research Center, which includes the NephEx sensor to measure the smoke’s optical density in addition to a pressure probe, accelerometer, and other components designed to be used on a descent probe for future planetary studies

In this webinar moderated by Flight Opportunities personnel, researchers will discuss how they fused the data from the three balloon-based sensing technologies along with data from a drone-based sensor to obtain a comprehensive understanding of fires on the ground. The session will cover the opportunities and lessons learned in collaborating across sectors — from academia to industry and small business to the government — as well as what’s next for the technologies.
