Principle Moons
Tethys (1000 km) impact crater same size as Mimas
Mimas (400 km)
Enceladus (500 km) Brightest body in the solar
system fresh ice
Iapetus (1500 km)
Iapetus' brightness varies from that of Enceladus
to coal black
Dione (1000 km)

Titan
Saturn's largest moon 5000 km Covered a thick
atmosphere which makes it effectively larger than
Ganymede But Voyager couldn't see the
surface Surface pressure 1.5 atmospheres Cold
atmosphere -180 degrees C Comprised of Nitrogen
(like the Earth) Reactions with solar wind
creates a thick smog in the atmosphere Methane
clouds occasionally form, and there may be
methane oceans on Titan Like Earth's Moon and the
other Saturnian moons it rotates synchronously

Cassini will arrive at Saturn this July!
The Huygen's probe will detach, enter Titan's
atmosphere, and land on it's surface The Cassini
probe will radar map Titan's surface like
Magellan did for Venus
