English: Clouds Over Ligeia Mare on Titan
http://www.jpl.nasa.gov/spaceimages/details.php?id=PIA18420 http://www.jpl.nasa.gov/news/news.php?release=2014-274 Click here for full animation of PIA18420 Click on the image for the full animation http://photojournal.jpl.nasa.gov/archive/PIA18420.gif This animated sequence of Cassini images shows methane clouds moving above the large methane sea on Saturn's moon Titan known as Ligeia Mare. The spacecraft captured the views between July 20 and July 22, 2014, as it departed Titan following a flyby. Cassini tracked the system of clouds as it developed and dissipated over Ligeia Mare during this two-day period. Measurements of the cloud motions indicate wind speeds of around 7 to 10 miles per hour (3 to 4.5 meters per second). The timing between exposures in the sequence varies. In particular, there is a 17.5-hour jump between the second and third frames. Most other frames are separated by one to two hours. A separate view, PIA18421, shows the location of these clouds relative to features in Titan's north polar region. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
