QUESTION:
Could a probe pass all the way through Jupiter?

ANSWER from Jim Erickson on January 29, 1996:
No, we can't presently build any device that could pass through Jupiter. 
As the Galileo probe dropped into the atmosphere, in the first hour the
atmosphere it was passing through was already at 300 degrees centigrade. 
Within 10 hours it would have been at a temperature where even titanium
will evaporate.  At the core of Jupiter matter exists as more of a plasma
than as a solid, liquid, or gas. 

But this doesn't mean that in the future a probe couldn't pass through the
upper atmosphere, and capture some of it for a sample return.  No studies
are on-going presently on this, but the future is still out there.  In 15
years when you get out of college, you might be able to propose a mission
to do this.
