Speeds of Sand Dunes on Mars
May 11, 2012 | Caltech

“Last year, images from NASA’s Mars Reconnaissance Orbiter captured sand dunes and ripples moving across the surface of Mars — observations that challenged previously held beliefs that there was not a lot of movement on the red planet’s surface. Now, technology developed by a team at the California Institute of Technology has allowed scientists to measure these activities for the very first time.” Quoted from the Caltech press release.
