Document Summary
Disc by galileo 1609 with 1st modern telescope: craters, j sat. E, g, and c prob have subsurface liquid oceans. Related to heating of tidal f from g field of j. Dark streaks (lines: io, europa, ganymede. Not stationary due to convective ice and tidal f of j. Rigid ice crust, under outer warm ice shell. Salty ocean may exist under crust: other in j system. Titan thick haze layer in upper atm: titan"s org haze layer. Cmps dev from ch4 and n2 triggered by e from sun. Sunlight reflected from lake in n pole. Many lakes with size changing from few km to few 100. Water/ice plum in s: e budget titan, lakes on titan, enceladus. 100 c which is 100c warmer than areas without plume. Tidal heatin warms rock to make convection. Break surface and erupt: other s sat. 62 sat with 13 larger than 50 km. Cassini observe equatorial ridge of lapetus and mimas crater.
