"NASA's Aerial Surveillance Detects Grape Disease in Breakthrough Discovery"

Researchers using NASA's AVIRIS-NG camera have successfully detected the Grapevine Leafroll Virus in California grapes before it could be seen by the naked eye. The camera, installed in an airplane, used spectrometry to analyze light wavelengths and trained machine learning algorithms to differentiate between healthy and sick vines. The system had an 87% success rate in spotting hidden virus and an 85% success rate in identifying visibly sick vines. This breakthrough could lead to the use of satellite surveillance for large vineyards in the future, helping growers make data-driven crop management decisions and potentially increasing wine production.

"NASA's Aerial Surveillance Identifies Wine Grape Disease in California"

Researchers from NASA's Jet Propulsion Laboratory and Cornell University have used a remote sensing technique developed by NASA to accurately detect a viral disease called GLRaV-3 in grapevines. The disease, which causes significant damage to the U.S. wine and grape industry, is typically detected through labor-intensive methods. By using machine learning and NASA's Airborne Visible/InfraRed Imaging Spectrometer, the researchers were able to differentiate infected and non-infected vines with 87% accuracy, providing grape growers with early warning to intervene. The study highlights the potential of remote sensing and machine learning in agricultural decision-making and pathogen surveillance efforts.
