So sending people in space craft with ion thrusters or nuclear propulsionto Mars has side effect?

I would like to ask another question. If we use space shuttle or any
other space vehicles that has a nuclear propulsion or ion thruster, it
may send people to mars but do take a long time. BUT there will be no
gravity inside the space shuttle and if people is exposed to a no
gravity environment for a long time, there will be bad effect towards
the human body( bone decay and etc) and also the humans pyschology
(boredom- most humans cant tolerate boredom).


So is there another solution or suggestion for this problem???

keep trip short, by using nuclear propulsion, mars is just a few months
away. or spin transit craft.

$ is the trouble, not the technical details

another way to go to mars

prepare the way with robot constructors
construct habitat in orbit around mars

send an *ark* of germ plasm to mars station/creche

by germ plasm I mean fertilized human (and other?) ova in deep freeze

thaw them out and quicken them in artificial wombs in Mars orbit

this way you could get 14000 people to mars orbit in a thimble

they may not thank you when fully grown tho, no not at all,

unless religion was used in the time honoured way

Better yet, don't send people to Mars...yet...

Spend the same money on robotic probes to the astroid belt, divert a few
mineral-rich astroids to Earth orbit, and mine them, also with robots.
Use the resulting richs to finance world peace, global food drives,
etc., and then use whatever money is left over for manned space exploration.

That suggestion makes too much good sense. Thus it'll never happen.

no rules" - In fact, war has been the very reason of having to deal
with the likes of others that haven't been playing by whatever rules,
such as GW Bush.

There are lots of asteroids, comets, and moons just waiting to give up
their riches. They are easier to get to than the planets because there
is no gravity to overcome either for landing or takeoff. These bodies
are more likely to have He-3 on their surface as well. The current
value of He-3 is about $ 4,000,000,000.00 a ton.
