Re: China wants to build a sustainable human presence on Mars. Here's how.

" substantial human presence " ?

Never going to happen in the forseable future !

Current technology requires something about the size of the Statue of
Liberty, just for a meager trip to our very close Moon.

Probes to Mars have likewise been very limited and unmanned.

It should be obvious to everyone that Chemical Rocket propulsion will
never cut it. All research should be to finding another means of
momentum. After all, aliens and UFOs have it don't they ? !
