atmosphere using heavy elements, or why not just waste lots of comets
sprouts
to thousand years due to low gravity solar wind strips away H and O
and N atoms.
First, can one add a buffer heavy gas to slow migration of H and O and
N to top of atmo where solar wind strips it off?. Noble gases come to
mind like Radon but I think they are anesthia gases, and I wonder if
any monoatomic gas would tend to pass into humans and do bad things.
Maybe use an exotic gas which hopefully one would find ready made in
an exotic comet after searching for this. Example, Sulfur
hexafluoride (SF6) is an inorganic, colorless, odorless, non-toxic and
non-flammable gas (under standard conditions) [bp -64 °C]. Typical for
a nonpolar gas, it is poorly soluble in water but soluble in nonpolar
organic solvents. It has a density of 6.13 g/L at sea level
conditions, which is considerably higher than the density of air
(1.205 g L-1 [4]).
Second, after reading online bio by space nuclear scientiest Zupero -
- http://www.neofuel.com/inhabit/inhabit.pdf - it seems even he must
admit space is hard to modestly colonize or move around in. We as
species use gravity, use entire lakes of water to refine metals or
grow things, and need protection from radiation - - so small stations
in space aren't optimal or even likeable except for space nuts. So
why not use in I know maybe wasteful way all the million comets to put
O/H2O atmospheres around moon, Mars, and Mercury for people to just
land in and breath adn refine metals and grove fish in (so normal easy
lives - - while each year landing thousands of comets to keep em
topped up, first drenching of comets with ground soaking up lots would
be biggest investment(. Why not easily and quickly make three more
water planets - - moon, mars, mercury???????? ceres? Maybe collide
thousand asteroids to make a new mini-planet? Having few fall-back
worlds for humans next thousand years seems only good real plan, in
next thousand years we will hav
