The lifetimes of dust devil tracks have been broadly based on their disappearance in successive images to be on the order of weeks to months on Mars as well as the Earth. Fading rates of dust devil tracks have not previously been measured, so with a series of images, we can study the fading behavior in order to calculate the implied rate of dust deposition over their lifetime.
