Detecting Dust Devils on Mars NASA

NASA’s Mars Global Surveyor spacecraft recently caught sight of a dust devil dancing across the Martian surface. While it isn’t the first of the tornado-like weather systems to be imaged, it is yet another reminder that Mars is an ever-changing planet. Dr. Ken Edgett, a staff scientist at Malin Space Science Systems in San Diego, Calif., regularly tracks the dust devils and studies surface features. As the operator for the Surveyor’s orbiter camera, he is one of the first to see fascinating images of the red planet. Dr. Edgett recently discussed the importance of dust devils and how they are transforming the look of Mars.
