Geology of the Solar System
Jupiter-Galileo and Juno
Huge, mostly hydrogen and helium
Red spot and swirls are storms in the atmosphere
shoemaker-Levy 9 was a comet impact
Core with liquid hydrogen layer
Magnetosphere
69 moons
Galilean Moons of Jupiter:
Lo: driest object in solar system, volcanic activity
Europa: silicate with water-ice crust, water ocean with plate tectonics
Ganymede: magnetosphere, thick ocean, thin oxygen atmosphere
Callisto: silicate core, not differentiated, many craters
Saturn-Voyager and Cassini
Huge and dominated by hydrogen and helium gas and liquid
Storms and winds
Gas giants
Iron nickel core
Deep liquid H layer
More than 150 moons and moonlets
Magnetosphere weaker tahn earth
Hydrogen and helium
Major moons of saturn:
Titan
Lander images of drainages
Bodies of water
Closeups of rounded rocks
Studied through Cassini probe and Huygens lander
Enceladus
Icy shell over liquid ocean
Iapetus
Dusty on front side
Ice on back side
Mimas
Looks like death star
