One issue with habitation of Mars is that it has a thin atmosphere. To paraphrase what this article states - the thin atmosphere causes problems. These problems vary from an inability to contain water, breathe, and so on. Ergo it is necessary for Mars to have an atmosphere before humans may attempt to habit there.
Earth retains it's atmosphere, in no small part, because of it's magnetic field. In turn the magnetic field is generated by the liquid core deep beneath this planet we call Earth. A magnetic field is necessary for Mars to maintain an atmosphere.
So we were having these thoughts on how to kick-start Mars' magnetic field.
It just struck me (pun intended!) that a rock may be the start of an answer. Our Earth collects anywhere from 5 to 300 tons of space-dust daily to 300 tons of space-dust daily. So why restrict ourselves to a big enough rock? Make it lots & lots of littler (pardon my English!) rocks. So many that the cumulative mass of the planet increases the pressure to the extent the core liquifies again.
Another alternative could be to have an external/artificial magnetic field. Earthlings have already proven themselves capable of sending craft as emissary to meet the War-Lord. Make it several craft instead! Each in an areostationary orbit (emulating the GPS satellites here on Earth), each transmitting over a broad-spectrum omnidirectionally. Voila!
Of course both solutions are easier said than done ... and mutually exclusive. The first, of course, is the issue of motive, and electro-motive power required. But they are available options that may be placed upon the table before they may be discarded (if so!).
