The methane-filled lakes on Saturn’s moon Titan are explosion craters, model predicts

Science
Sept. 9 (UPI) -- According to a new model developed by planetary scientists in Italy and the United States, many of the methane-filled lakes on Titan were likely formed after explosions of warming nitrogen left dozens of empty craters dotting the surface of Saturn's largest moon. Outside of Earth, Titan is the only planetary body in the solar system known to host stable liquid on its surface. While Earth hosts bodies of water, Titan's lakes are filled with liquid methane and ethane. On Earth, methane and ethane typically exist in gas form, but subzero temperatures on Titan allow the hydrocarbons to exist in liquid form. Previous models suggested Titan's lakes were formed over thousands of years as the liquid methane and ethane precipitated by Titan's clouds dissolving the moon's bedrock ...

NASA considering missions to comet and Saturn's Moon Titan

Science
Dec. 20 (UPI) -- NASA is considering possible missions a comet and Titan, Saturn's largest moon. The space agency selected the two concept finalists on Wednesday.The selected missions were two of 12 proposals submitted as part NASA's New Frontiers program."This is a giant leap forward in developing our next bold mission of science discovery," Thomas Zurbuchen, associate administrator for NASA's Science Mission Directorate in Washington, said in a news release. "These are tantalizing investigations that seek to answer some of the biggest questions in our solar system today."The Comet Astrobiology Exploration Sample Return mission, or CAESAR concept, proposes a NASA-funded visit to 67P/Churyumov-Gerasimenko, the comet visited by the European Space Agency's Rosetta spacecraft and Philae lande...
