A great and powerful Martian dust devil swallows another in new video

Something about this time of year on Mars is reminiscent of 1939's The Wizard of Oz. Maybe it's the ruddiness of the planet that gives off its own natural sepia tone like we see in Victor Fleming's film adaptation. Maybe it's the tornadoes, sometimes so tall they seem like they could lift more than a few farmhouses. But one thing's for sure about these freakish alien dust devils: You're definitely not in Kansas if you see them. More like 140 million miles over the rainbow in space.&nbs
