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.

That ship sounds possible, but somewhat more expensive than can be
built in the near future.

However, like Mr. navia pointed out, at the moment the technology to
actually land humans on Mars doesn´t exist.
