New Mars Forums

I don't come from a scientific background, but I do and always have had a fascination with the Rad Planet and Space exploration in general.  I have an idea which may be unrealistic, but, as I've never seen or heard it discussed, I'm frustrated at not knowing if its feasible.

What modifications would have to be made to the International Space Station in order for it to undertake a manned mission to Mars?  A propulsion unit and landing vehicle spring to mind immediately, perhaps more in the way of life support and supplies.  Maybe even stiffening of the superstructure so that it can survive the acceleration..

But surely, the hard work is already done?  In addition, the Space Station is a truly international effort already - so a Mission to Mars using it would truly be a global undertaking.
