Take a look at a 12 inch globe of the Earth as sold by Walmart. Now note
the scale, 1 inch = 660 miles. The ISS orbits 225 miles or so above sea
level. This works out to about 1/3 inch or roughly 3/8 inch above this 12
inch globe.
Science teachers out there, tell this to your students for it will greatly
unimpress them.
To spend billions of dollars on space ships which literally skim the
Earth's atmosphere is absurd.
Even way back in 1951, we built a ship for mere millions of dollars capable
of carrying 44 passengers and a Noah's Ark full of animals to make a
successful landing on the planet Zyra. Our technological prowlness seems
to have seriously regressed in the intervening half-century.
No further manned space vehicle projects should be developed unless there
is a worthwhile destination; ie, Mars. Instead of 3/8 inch, it would be
more like a mile. Now, THAT should impress those school kids.

Is it a full moon already?
Anyway, your first point is sort of valid, but the destination in distance
is not the point, the environment is, and close enough to home to make a
cock up and get back.

Using SI units would help them reach Mars, sticking to "about 1/3 inch
or roughly 3/8 inch" almost guarantees that a future Mars mission will
end up very wet, 23 miles east of Cape Cod.

I don't believe you build a craft down here on earth and expect that you
will have thought of everything prior to going on a voyage all the way to
Mars. You need to do the research first both engineering and physiological.
You need to to simulate that as best you can. What ever goes to Mars is
probably going to need to be assembled in low earth orbit. Many of these
topics are being explored on ISS, along with quite a few ongoing
experiments. Low earth orbit is a foothold or stepping off point.

To boldly go where the exploration of a physiological topic that serves
as a toehold or jumping off point.
