Why on Earth Mars? You still need zero-volume delta joint vacuum suits
there, because you still see 98% of the same force as in Earth orbit
or Moon surface. Water? There's water on the Moon (unless the neutron
data from Lunar prospector is totally bogus which I don't believe),
and probably even hydrogen implanted into lunar regolith. In a pinch
you can always haul some 10 t of the stuff to kickstart a
colony. Oxygen? Darn Moon is made from some few 10% of that stuff,
bound in alumosilicates. Lead hydrogen over heated regolith bricks and
you'll get water. Electrolyze water, and you'll get hydrogen and
oxygen. Whether Moon or Mars, you have to live underground to escape
from radiation and prevent rapid decompression due to leaks, and
vacuum is about the best thermal insulation there is. However, you
can't do vacuum industrial processes on Mars, because the atmosphere
is in the way, and insolation density is a bit thin out there. There
is probably a permanently insolated mountaintop at one of the lunar
poles, conveniently near the water bound in the cold trap below.
Manned mars missions before doing the Moon first makes zero sense. It
only appeals to the scientifically illiterate public which thinks Mars
is somehow similiar to Earth. It is not. If you screw up there you die
just as surely as on the Moon. More so in fact, because there is no
hope for a rescue mission. And you don't even have to go to the Moon
to work there. You could telecommute there from the living room, at
the speed of light.

Indeed. But why should people stay and work on Mars and not on the

It is rather a very expensive suicide mission.

Honestly, which disabilities would give you an advantage? I understand
that weighing just 25 kg can give you advantage for long spaceflights
without a closed-circuit ecology -- if you can survive the launch and
reentry -- but what else?

Have you seen what happens to people and animals after one year of
microgravity? Higher organisms are not made for space. They need
simulated gravity thus negating all advantages disabled people might

I see the disabled playing cyborg first, but little else.

Yes, space is rather unforgiving. The less reason to go galumphing
about in a space suit, and use teleoperated machinery instead.
