What was the purpose of the Galileo probe's descent into Jupiter's atmosphere?

Answer

To study the atmospheric layers before being destroyed.

The Galileo probe was an atmospheric probe designed to transmit data for about an hour while descending through Jupiter's layers until the increasing pressure and heat destroyed it; its purpose was atmospheric study, not surface landing.
