Their bones become brittle, space radiation destroys surely their

What pure, unmitigated cow excrement.

All the scientific literature pointing to bone mass loss
is NOTHING to you.


It's nothing that's relevant, if that's what you mean. Bone loss is caused by microgravity, not by being in space. It's easily mitigated through artificial gravity.


Obvious.

But is equally obvious that you would need a spaceship of
enormous size to make it practicable isn't it?

A spaceship that leaves the current ISS as a dust speck behind.

With all the problems of the ISS, a very SMALL spaceship,
you talk about artificial gravity as everybody could do it with the snap
of the fingers.

Obviously it CAN be done in the next century. But not with current
technology and budgets!

All exploration beyond the moon can be done by robots ONLY with
current technology.


Of course if you hate science this is no wonder.


But I don't, of course.


All the research reports pointing to the hazards of space radiation to
vital organs like the brain, the retina, etc etc is all "bull***"
to you.


No, the research is valid, it's your conclusion that is bull***. Again, it's radiation that is the problem, not being in space, and radiation is easily stopped through shielding.

You would need several meters of shielding, what wxould enormously
increase the mass of the spaceship.

So, you are proposing a "2001" film size spaceship, shielded from
radiation by several meters of, say, water.

This is an enormous mass to be put into orbit, and it is completely
UNTHINKABLE by current technology. The moon spaceship is quite big,
by current standards, but offers no shielding, and no artificial
gravity.

What will be the consequences of micro-gravity in the moon for more than
1 months?

Nobody knows, Appollo stayed only a few DAYS.

How will the future moon base shield themselves from deadly
sun flares?

You have to put heavy equipment to build an underground base.

All this is just science fiction now. The objective of this
huge program is to build a rehearsal of Apollo with the same
objective: spend a lot of money for no scientific return
whatsoever.


You might as well claim
that running a nuclear power plant is impossible -- after all, that produces deadly radiation too.

In short, you pointed out two easily-solved problems of the space environment, and then leapt (incorrectly) to the conclusion that "After 1 to 1.5 years in space, humans start decaying quickly." Utter nonsense.


"Easily solved" hmmm. Then tell your solution to NASA because they are
funding actively how they could solve those problems!
