Cool. It would be nice to have kind of live transmission from next probe
somewhere there. All those Jupiter ascents and descents, watched from a
"window inside a monitor". Almost like being there, minus pesky AI trying
to freeze me out of the ship and stupid####### benevolent aliens trying to
lure me into journey to nowhere...

Yeah, I can bet they plan to send a chorus there, too.
Those guys talk like this is a five year long project, after which all is
set and running. But in reality, especially nowadays-like reality
(including budget constraints and lack of political will), I guess the
shortest time to have it is more like 30 years. If all goes well.
BTW, I think I never have been a big fan of sending supercomp up there. At
least not after I learned that space is nasty place to live without good
shielding. I guess this haven't changed recently? Also, CPUs being sent
there are actually special radiation-hardened versions AFAIK, and I think
much more pressure is put on their reliability than speed. So they are not
quite good as supercomp building blocks and average PC is no good when
being zapped by ultrafast particles every few minutes or exposed to CMEs
from the Sun...
BTW2, maintaining this behemoth would be a (logistical) nightmare if it
ever got built. I mean, it is ok to send people to the Moon and live in a
permament base for purposes other than taking care of poor man's copy of
Google computing container, full of hardware designed in tech process
generations behind the newest one (thick paths last longer)...
BTW3, I love(d) the story of maintaining/debugging Deep Space remotely:
Just my random thoughts on the subject. Will be happy to be corrected by
