Hallo,

hier ein ausführlicher Text von R. Hoagland in dem er beweisen will, dass Galileo bei seinem Impakt in die Jupiter-Atmosphäre sehr wohl implodiert sein könnte.
Laut einem Versuch aus dem Jahre 1962 könnte das Plutonium 238, das auch Galileo mit sich führte, implosionsfähig gewesen sein:

"However, a little-known US nuclear weapons test, carried out underground at the Atomic Energy Commission’s Nevada test site (now operated by the Department of Energy), demonstrated in 1962 that “reactor-grade” plutonium – a mix of isotopes, including plutonium-238 – could be successfully imploded. Because of the extended Galileo mission, and the pre-production of the plutonium-238 fuel capsules before its launch (coupled with their unique design – which incorporated a layering of neutron-emitting uranium-234 into their construction), long-term creation of significant quantities of highly fissionable plutonium-239 across the fifteen years since the mission was launched cannot be ruled out of the eventual Galileo plutonium ceramics … by the time they were deliberately plunged into Jupiter. "


"In other words, the physics of implosion dictates that extreme external pressures, reaching tens of thousands of Earth normal atmospheres (1 “bar”), can initiate supercriticality in certain plutonium alloys. In a weapon, this is achieved by a carefully shaped charge -- to drive explosion shockwaves inward … imploding the metal to “supercriticality.” In the Jovian context, this pressure naturally exists … beginning about 600 miles below the visible cloud decks -- far in excess of anything Galileo was expected to encounter on entering Jupiter’s upper atmosphere in September, 2003, before being totally destroyed. Van der Worp, in proposing about a nuclear explosion after the first few seconds of Galileo’s entry, had apparently vastly underestimated the efficiency of friction in Jupiter’s increasingly dense atmosphere, which would slow the various components to a virtual standstill, long before they reached these critical “crush depths.”

So, even on reexamination, van der Worp’s ideas seemed irrelevant to the mystery of Jupiter’s new spot—

Until … I thought about the “time lag.”

Galileo slammed into Jupiter’s atmosphere September 21st. Meeckers photographed his mysterious “dark marking” October 19th. If Galileo, by creating an explosion, was somehow responsible for this new blemish … why the one month lag between these two events? Van der Worp’s scenario had a Galileo plutonium explosion happening almost as soon as the spacecraft hurtled into the Jovian atmosphere ….

Suddenly, I realized that this was the missing puzzle piece – apparently not fully appreciated even by van der Worp; that time lag could be the key to resolving this entire “Galileo bomb” scenario … and the mystery of Jupiter’s “new spot.”

It all hinged on how far into Jupiter the spacecraft (or, more accurately, it’s plutonium canisters) would have to plunge – intact! -- before encountering external atmospheric pressures sufficient for “implosion. In other words, how long would it have really taken Galileo’s plutonium -- assuming it survived its fiery entry in the first place – to have fallen ~600 miles …?

I began to sketch out a possible scenario. "
