Researchers have spotted surprisingly diverse landscapes on Titan, from broad planes to sandy dunes and even rivers and lakes. And recently a ribbon of exposed bedrock ice that wraps nearly halfway around the moon was spotted there too.
Los Alamos National Laboratory scientists and an international research team have announced discovery of molecular oxygen ions (O2+) in the upper-most atmosphere of Dione, one of the 62 known moons orbiting the ringed planet. The research appeared recently in Geophysical Research Letters and was made possible via instruments aboard NASA's Cassini spacecraft, which was launched in 1997.
Titan Saturn System Mission (TSSM) is a joint NASA/ESA proposal for an exploration of Saturn and its moons Titan and Enceladus, where many complex phenomena have been revealed by the recent Cassini Huygens mission.
