Re #7
If you're using astronauts who exhale and excrete, CO2 & minerals are
free in space. You don't need to bet anyone's lives on the farm - just
let it be the difference between a minimal & a nice, long mission. The
food the farm "replaces" take up space, has to be landed, etc. Space
farm technology isn't rocket science, and much of it could easily be
pre-tested in LEO. The fiddlework and nicer diet implicit in a farm
have very real psychological benefits for astronauts who'll be packed
in close quarters far from home for a *long* time.

resp:7 I would guess the major stumbling block in traditional scenarios
is building the space station. However, we're already doing that. If
we have a space station, why not use it to enhance the mission? You
don't have to get too elaborate.

Re #11: Okay, what would you enhance?
The "traditional" view of the mission-staged-at-a-space-station had
the station acting in one or more of these roles: fuel depot for the
deep-space ship, final assembly plant for the deep-space ship, quarters
for the crew and assembly workers, and isolation site for people and
samples returning from other planets.
The ISS doesn't have much in the way of room for extra crew, has no
tankage facilities or assembly bays, and no isolation labs. On the
other hand, it has plenty of costs that the administrators would love
to bill to other projects (like Mars missions).
I suppose the question is: even if you could possibly use it, would you?

I don't know. I don't know much about ISS, it's function, or it's
capabilities.

For information on ISS, you should visit NASA's web site.
