Will Dragonfly find dust devils on Titan?

Earth and Mars both are known to have swirling dust devils moving along their surfaces. Saturn’s large moon Titan might have them, too, according to a new study. If so, NASA’s planned Dragonfly mission will be able to find them. Source: https://earthsky.org/space/saturn-moon-titan-dust-devils-dragonfly…

Dust devils may roam hydrocarbon dunes on Saturn’s moon Titan

Meteorological conditions on Saturn’s large moon Titan, the strange, distant world that may be the most Earth-like in the solar system, appear conducive to the formation of dust devils, according to new research in AGU’s journal Geophysical Research Letters.
