And THAT is the real show stopper. That technology doesn't exist today.

Not true. The Earth exists.

So, using lunar materials, we just build a very large radiation shield
around a large rotating cylinder... with a surface area of several
acres, and a mix of plants and animals. Lakes would cover about 3/4 of
the surface area. That should support one or two astronauts.

The required optical system for getting sunlight in while one is
radiation-shielded from all angles is described on my web site at:

Of course, launching such a large and heavy object, constructed in
lunar orbit, on a trip to Mars would be energy-intensive, but one
could just use giant solar mirrors to boil reaction mass. So even in
the *worst-case scenario* where conventional spaceflight technology is
wholly inadequate to get humans to Mars, it *can* be done.

A flying bedstead with lots of little rockets would allow the
astronauts to land on the Martian surface.

To eliminate confusion: this is not being proposed as the only, right,
or best way to go to Mars - it is proposed as a way that would work
even if all the objections of people who say the conventional way
doesn't work were valid. If we want to go to Mars, we *can* go to Mars
- that's a fact, not a theory.
