Winds... - Sol 103 (GIF-Movie; credits: NASA/JPL-Caltech/University of Arizona/Texas A&M University )

NASA's Phoenix Mars Lander's "Telltale" (such as the anemomether) catches a breeze as clouds move over the Landing Site on Sol 103 (such as Sept. 7, 2008), the 103rd Martian day since landing.
Phoenix's Surface Stereo Imager took this series of images during daily Telltale monitoring around 15:00 M.L.T. and captured the clouds moving over the Landing Site.
Phoenix can measure wind speed and direction by imaging the Telltale, which is about about 10 cm (approx. 4") tall. The Telltale was built by the University of Aarhus, Denmark.
