Thanks for your interest in Galileo and for your question. I'll guess that you mean the encounter of the Galileo Probe with Jupiter's atmosphere on December 7. The Doppler Wind Experiment actually used the tiny changes in the radio signal as the Probe descended to tell us about how the Probe was being moved or shifted off its course by the winds in Jupiter's atmosphere. You'll probably come up with some of the right answers. Well, that's the main list of things the encounter was designed to teach us.
People have very different responses to the same collection of facts.
Thanks for your interest in Galileo and for your question. The question you ask is one of those tricky ones that needs some facts AND some opinions to create an answer. Human beings have always been explorers and adventurers. Not all of us, but some of us have always been that type. Planetary exploration is part of that questioning process.
