Greetings, i'm new at these forums....
Please apolagise me about my bad English.
I've read most of the posts in this thread, and i have same ideas i would like to share.
To start we must understant what is a magnetic field, and how is it formed.... Unfortunelly, we can only guess. Most of the magnetic fields in rocky planets (and moons to) are formed by a tidal wave model (gravity), in Mercury is the gravity of the sun (the result is a magnetic field stronger the Earth), Venus and Mars have no MF, our magnetic field also uses a tidal wave model, our Moon stretches the Earth core and heats them. The stranger MF in the solar System is from one of Jupiter's moon's, Ganymedes, its week, but is there, it is also formed by a tidal wave model, the orbital resonance betwin Io, Europa and Ganymedes heats is core....
The second thing we need to have a MF is an internal solid core surrounded by liquid layer.... the diference betwin this two layers will form a MF.
Mars had a MF field in the past, but can he be reactivated??? I dont know the answer.... no one does.
Mars MF stopped 4 bilions years ago, all the south pole of Mars is magnetised as prove of it, but not the north pole, why??? 3.9 bilions years ago a Moon sized objected crashed against mars in is north pole, it seems that area became molten lava and was not magnetised again. The issue is that such a huge objected could have reacted with the martian core, making him unviable to produce a MF again.
our best shoot to try to reactivate it, is try to replicate a Earth-Moon simbiosys.... But how??? Our Moon is around 1/6 of the Earth mass, if we could put an objected with the same porpotion in Mars orbit we may have same luck. The combined mass of Ceres and Vesta (in the asteroid Belt) is almost 1/6 of Mars mass..... It won't be quick...... We don't even know that will work.... But is our best shoot.
With out a MF, terraforming Mars is just useless waste of time, a dome (or hundreds of them) would be so much more cheaper.
About the impact theory....
Forcing asteroid or comets to crash into Mars would have a big issue..... Mars as a very thick atmosphere, every time we crash such objects into Mars, a portion of is already very thick atmosphere is directly ejected into space (depending on the object size), i would say, everything bigger then 10km would eject much more gas then then desirable.
