Re: Article from space.com -- "Deadly Radiation Spurs Life"-Reply

And it's not inconsistent with bacteria and
similar organisms being able to survive
and thrive in that environment. Guess the
reporter may have had some cognitive
dissonance in putting that story together. I
would think that we in the profession would
understand what was being said, but what
is John Q. Public going to think about that
story?

Just as an aside, where can I find the
original NASA press release? Is it on the
NASA website?

Jim, 

What this poor reporter is probably using
as a reference was a NASA press
release from the recent flybys.  The press
release was in typical NASA
tekie speak and referred to the radiation
belts around Jupiter that are
much the same as our Van Allen Belts,
just a whole lot stronger.  In this
case, the dose received by the Galileo
space craft in each flyby would be
fatal to a human.  If you saw/read all the
reports, it was almost fatal to
the spacecraft; one instrument is still
having problems and the main solid
state memory module has some neat
glitches that ground controllers had to
program around.  I'd have to go searching
to get the exact dose (I get
around 15 NASA briefs/day) but it was
definitely in the human lethal range
(on the order of 100's of rads of high
LET).  If I can find it, I'll post
it.
