Cassini spacecraft reveals global energy imbalance of Saturn
West, Robert A.; Nixon, Conor A.; Guillot, Tristan +16 more
The global energy budget is pivotal to understanding planetary evolution and climate behaviors. Assessing the energy budget of giant planets, particularly those with large seasonal cycles, however, remains a challenge without long-term observations. Evolution models of Saturn cannot explain its estimated Bond albedo and internal heat flux, mainly …
Surface properties of the seas of Titan as revealed by Cassini mission bistatic radar experiments
Soderblom, Jason M.; Lorenz, Ralph D.; Tortora, Paolo +9 more
Saturn's moon Titan was explored by the Cassini spacecraft from 2004 to 2017. While Cassini revealed a lot about this Earth-like world, its radar observations could only provide limited information about Titan's liquid hydrocarbons seas Kraken, Ligeia and Punga Mare. Here, we show the results of the analysis of the Cassini mission bistatic radar e…
