I wouldn't be so sure. For most purposes, such contamination (N2,
CO, or O3) is unacceptable. Especially CO and O3, as those are quite
poisonous. But on Mars, where nobody is going to breathe them,
it's not a concern. And CO and O3, far from being a problem for
an oxidizer, would give a little more "kick" to the O2.

Unfortunately, without sufficient space travel shielding, as well as
surface EVA shielding, breathing whatever isn't your biggest problem,
it's the least of your problems.

Going "one way", now that's doable. Staying warm is even doable.

If sufficient energy is delivered from Earth to the Mars surface, a
CO2--CO/O2 process will in fact keep you breathing while the cosmic
and galactic radiation finished you off.

At least whatever returns to Earth in a body-bag will be sufficiently
sterile.


Be advised; The following is yet another paid infomercial on a means
to an end, of getting your sorry butt to/from places like a frozen and
irradiated to death planet like Mars.
