Sounds like it'd be easier to make Earth more like Mars. Especially since we've already got a pretty good jump on that...

Sending humans to Mars apropos of nothing is a fool's errand. For every one person NASA could send, we could send a dozen or a hundred robotic science facilities. Colonizing Mars is trading temporary paradise for permanent hell when we should be designing interstellar colony ships.

The other ball of wax is that it would also need a global magnetic field like earth. Otherwise, any atmosphere created would eventually be stripped away by solar wind.
