Ancient cosmic impacts on Mars might have created powerful wind vortices similar to sideways tornadoes, and the whirling winds would have rolled across the Red Planet's surface like barrels, a new study finds. The streaks that those winds left behind could help reveal details about Mars' past, the researchers said. These streaks can extend quite far from the impacts that created them. For instance, on the 12.4-mile-wide (20 km) Santa Fe crater in the flat lowland region in Mars' northern hemisphere known as Chryse Planitia, the streaks can extend more than 72 miles (120 km) away from the point of impact, the new study found.
