Are the protons from the latest round of CME's going to fricassee the
crew of the ISS, or does the geomagnetic field afford sufficient
protection? That is, will any biologically meaningful amount of
radiation above the norm make it all the way down to LEO where the ISS
orbits (~380 km, inclined ~52° from the equator at the extremes)?

They are vulnerable--but have a "radiation hardened area" which offers
some protection.

They are expected to receive no more than half a percent of their
monthly allotment of rads when the solar wind hits.

They will get radiation cataracts over time - in a year or three.
Note that the maximum allowable ass-tronaut whole-body radiation dose
is set even higher than that of nuclear workers, which is set much
higher than any Offically safe level because otherwise there would be
no allowable nuclear workers.

They're gonna get lightly braised, but not Officially so. A "Mars
mission," wholly out of Earth's magnetosphere, would get done over
easy.

In addition their muscles will atrophy and their bones will turn to
chalk because of the 0 g. The trip to Mars is a suicide mission even if
it succeeds in getting a human footprint on the planet.

With current propulstion technology, long manned mission are a loosing
proposition.

Ughhhh

Just SPIN the damn thing to get a decent one G environment......

I love NASA but all that ****ing around with ants and frogs in low earth orbit
wasting billions and yet they have never EVEN tried spinning capsules on cables
to combat zero gee

sometimes I honestly think they DONT want to go to mars...

Radiation is another issue though..

take care

Bll....

Not so fast. If the radius of the spinning element is too small, just
turning ones head produces some interesting Coriolus effects in the
cranial cavity. Nausea and pain ensue. For a big enough spinning element
you need new propulsion technology which is nowhere in sight at present.
And it is doubtful the taxpayers will put up with footing the bill, as
there is no national defense function served by planting a human
footprint on Mars.

When a good profit making goal is found for such a trip, private capital
will finance the appropriate technical innovations to carry it out. But
a government boondogle cannt do much better than to loft Space Station
Fubar- Alpha ******** One which has to be reboosted frequently because
its orbit is low to accomodate the pitiful space shuttle vehicle, a
sterling product of the 70's .

Think of a good profit making reason to go to Mars. When you have
thought of one, let us know.

Surely.

Where is that, beside the broken excersize machine, or behind
the faulty water reclamation analyser?

Or do you mean the dentist x-ray cover that the Soyuz brought
with them to allow them to huddle under in the event of?

I can't always tell when an airplane is turning, when I'm sitting in my
seat and reading a book. But then when I move my head around and get
dizzy, I know.

Not necessarily, if you have a long tether between the capsule and a
counterweight, like supplies or fuel for the return trip. Tethers are
cheap. But that assumes a boost phase and then a long coast. Not sure
how to handle a powered trip all the way in, as from an ion engine which
would be far too wimpy to simulate gravity by its acceleration, but surely
strong enough to make navigation difficult if it's spinning around.

That's not really a significant problem. Travel time would be about 6
months each way. With a proper exercise regimen, people can handle
that much time in 0 g without a problem.

Not necessarily. Though the risk would be quite high, failure would
not be a certainty.
