Voyager 2 has discovered a 3-mile-tall mountain on one of the moons of Uranus.
It really sticks out like a sore thumb on the photo I saw on TV. The only
thing it could be (my layman's opinion) is a volcanic cone, probably extinct
like Mount Shasta in California, but if Jupiter's Io is any example not
necessarily. The only major open question is what kind of lava it used. It
would have been too cold during the past 4 billion years to be basalt lava, so
probably water ice or ammonia (or nitrogen or methane if it is really cold
there and the volcano is recent); it couldn't be a very early volcano from the
first half billion years when moons were still very hot because it would have
been bombarded out of existance by all the meteors that were keepin things so
hot then by bombarding everything in sight (layman's opinion again). So, what
do the rest of you think, volcano as I claim?, extinct as I guess?, what kind
of lava do you guess?, how long since active?

When are we gonna get that damn ion rocket developed so we can send
Mariner/Viking/Galileo-class spacecraft (orbiter/lander) to all the outer
planets without having to wait ten years to get the craft to the very outer
ones via gravity-assist from the nearer ones? Those Uranian moons look as
interesting as Saturn's (although nothing is as pretty as Dione as far as I've
seen to date, but then I haven't seen Uranian moons in color yet).
