Which planets and moons will be inhabited by humans in 100 years ???

Do you think there will be human cities on Mars, Venus, Jupiter,
Saturn, Callisto, Io, Ganymede, Europa, Titan, Oberon, Titania,
Triton, Sycorax and Thebe in 100 years ???

Nope.

In forty years we've not taken any substantial steps toward attaining
those goals. To expect to come anywhere close to manned settlement in a
little more than twice that time is unrealistic (without 'outside' help).

In a hundred years we'll be lucky to have a settlement on the moon, and
at the most, temporary/rotating (scientific) settlements on Mars. And
most of this will be accomplished by private industry. We'll see the
moon and the asteroids being mined long before we see "human cities" on
the moons of Saturn. And we may not see any of that for centuries.

And you'll never see human cities on Jupiter or Saturn. Those planets
are largely liquid and the gravity would be crushing.

Gas giant planets are largely liquid?

Only in Ames and Iowa City!

Every month or so, using a fictitious name, this troll floods 5000
newsgroups (all cross-posted to a single low-traffic but unrelated
newsgroup) with superficially relevant comments. The purpose is to disrupt
with off-topic crosspostings.

Like all trolls, he means to annoy and disrupt. The tracking newsgroup is
the way he "keeps score" of how much damage he has caused. Don't put
yourself on display in his trophy case.

If you feel you have to respond to one of his posts, please don't crosspost
to his tracking newsgroup.

Like all trolls, the way to handle him is to IGNORE him.

Take a few minutes of your time and check out the following score cards to
see firsthand what this perverted troll is doing. I promise, you'll be
amazed at just how active and perverted he is. You will see firsthand the
troll's work and his trophies. You will see into the sickness and darkness
of the worst troll on the internet today. Read some of his posts and look
at the headers. You will see than no newsgroup is immune. You will see
flamewars started, some containing over a hundred messages.

Browse the can.uucp newsgroup, his old score card, for Karl-Hugo Weesberg

Browse the is.matur newsgroup, his old score card, for Dan Simper.

Browse the scot.tld newsgroup, his old score card, for Bruno Beam.

Browse the israel.amix newsgroup, his current score card, for Paul Eisner.

He is known as the "anagram troll" because his fictitious names are often
discovered to be anagrams (for example "Dan Simper" is an anagram of
"Spiderman", Bruno Beam is an anagram of "Unabomber").

This guy is a serious troll with a serious problem. Don't be one of his
trophies.

Chances are that I don't subscribe to this newsgroup. I am simply
monitoring the newsgroups the Anagram Troll is using as his score card. Any
posts from me are a result of that monitoring. I normally only post to the
newsgroup being spammed, not to the score card newsgroup, thus I will not
see any replies directly to this post.

Above all, please do not allow him to start a flamewar or extensive
discussion in your newsgroup. He thrives on that. If it is too late, don't
crosspost to his score card newsgroup. That trophy count is his motivation
to continue trolling. Please help stop him in his tracks.

We should have outposts of about a hundred people in geostationary
orbit (sooner or later someone will consider how much money there is
to be made by refueling geostationary satellites as opposed to just
ditching them when the fuel runs out) and the Lagrange points (solar
power stations), a few small cities of several hundred on the moon
(plentiful resources and very close to Earth, extensive astronomical
observatory on the far side...though hopefully officialy we'll be
calling it Luna by then), two or three outposts on Mars of about a
hundred people each (continuing scientific surveys...if no indigenous
life is found, early terraforming experiments are begun i.e. adapting
Earth plants to the Martian atmosphere and soil in covered domes), and
some asteroid belt mining outposts of a few dozen people each for
mining metals for transfer to Mars or lunar orbit. A lot of blue-green
algae is injected into a relatively benign layer of Venus' atmosphere
as another attempt at terraforming with a permanent unmanned orbiter
to monitor the effects.

Plus permanent robotic unmanned scientific outposts on/around
Ganymede, Titan, and possibly Triton capable of making regular visits
to the other moons of Jupiter, Saturn, and Neptune as needed. We
'sacrifice' an orbiter/lander once in a while to closely study Europa
and Io which is then boosted towards Jupiter impact before it fries
from the radiation.

Why would you put an astronomical observatory on the Moon? You've still
got gravity to interfere with your instruments and you only have half
the sky available at any time. If you have the technology to build an
observatory on the Moon, you certainly have the technology to build it
in space, which would seem a far better choice.

Gas giant planets are largely liquid?

"Like Jupiter, Saturn is largely liquid. The slightly higher
concentration of helium relative to hydrogen in the atmosphere is
thought to be be due to the colder temperature of Saturn. Under these
colder conditions, liquid helium does not dissolve in liquid hydrogen
and drops of helium sink to the center, depleting the outer regions in
helium. Speculation on Saturn's internal heat source is similar to that
for Jupiter."

The belief is there is a liquid hydrogen ocean on the surface of both
planets. Regardless. There's no tenable surface for settlement as the
original poster wanted to believe.

Well, at the very least a good radio observatory shielded from
Earth-bound interference....and you might be able to build the
observatory more easily out of the resources found there rather than
having to build it in space by ferrying resources or boosting the
completed observatory to that location. Of course a handy trojan
asteroid in Jupiter's orbit could be used for this function.

Okay, a radio observatory makes sense. I'd still say space for an
optical observatory, but building it and launching from the Moon might
be sensible.
