Re: Space travel by humans is not possible now

Please provide a single example of someone who "thinks it is the

Mr McCall for instance.

Exploration was always done "in person" before robotics existed.
Mr McCall fails to grasp what is the difference now, and naively
proposes sending people to explore, as if those people were going
to some far away continent, not unlike earth.

For instance

So you take it with you from the start. All that requires is
planning.
<end quote>

The difficulties of hoarding 2-3 years worth of supplies
for several people and the return trip fuel
somewhere in Mars, when all mankind has been able to do to date
is to land a few KILOGRAMS there, is completely beyond his
grasp.

Just put some people in a rocket and there you go.

He wasn't even *aware* of the problem of landing on Mars for
a really heavy spaceship loaded with a life-support system for 4 people.

Nobody knows how to do that except Mr McCall of course, that just fires
the rockets and lands...

As we have always seen in TV shows and science fiction books.
