That's a tricky one, as humans don't do well with radiation, charged particles:

Our heavier atmosphere helps to protect us from being constantly being bombarded by things like X-Rays and Gamma Rays.
Mars has no north or south poles, navigation would be a bear.
This is indeed an engineering marvel, otherwise we'd have done it long ago, not to mention other countries would simply do it too: it has simply become much more routine now that we are figuring things out.
This is very much like the Gemini Missions: Buzz Aldrin made it look so simple while he did his EVA... Never mind the fact that People like Ed White, the first American to walk in space nearly died because he almost didn't make it back into the capsule. Micheal Collins too, but the real scary one was Gene Cernin because he was over heating, was virtually blind and his heart rate was dangerously high. Everyone before Aldrin helped figure it out for him to do a flawless space walk. No one told any of these guys that if they couldn't get back into the capsule they would be cut free from the craft
to drift in space before eventually burning up as their bodies reentered earth's atmosphere.DIVAIR

I suggest we sent Xi Jinping to Mars.
After all, it *is* the "Red Planet", and it is Uyghur free, to-boot.
I suggest we don't bring him back, though.
