NASA technology can spot wine grape disease from the sky. The world’s food supply could benefit

, an assistant professor of grape pathology at Cornell University and a lead researcher on the project. “The next step is scaling to space.”

The implications of such a venture — if successful on a global scale — could “benefit the whole food system,” Gold said. But that’s still a far-off vision, Pavlick said, with much more research necessary before the spectrometer is set to head up to space at the end of this decade. This latest study, focused on vineyards and the grapevine leafroll virus 3, or GLRaV-3, is a promising example of how this powerful technology can be leveraged, he said.

Researchers flew the AVIRIS-NG, or the next-generation Airborne Visible/InfraRed Imaging Spectrometer developed at JPL, over about 11,000 acres of vineyards near Lodi. The spectrometer captures data from hundreds of channels of light, including those far beyond the visible spectrum — “down into the ultraviolet and well above the infrared,” Pavlick said.
