All these worlds are yours - except Europa. Attempt no landing there.
-- Arthur C. Clarke (2010 - Odyssey Two)

Galileo, launched in 1989, passed away by hitting the dense atmosphere of Jupiter three days ago, on September 21.

The decision has been made quite a long time ago, to prevent any possible collision with Europa, which salted water could hide some form of life.
