When in doubt, ask an autistic. Chances are, they're obsessed with what you need to know.

Huh?

Coz I'm confused-I saw a thread about this not long ago (yours?) and somehow the topic seems to have migrated to Threadkiller Land. I suddenly wondered whether I'd been posting on the wrong thread all along...

Nope I put it in Threadkiller Land here intentionally. Barely anyone had responded to it on my facebook so I posted it here since it seem to kill conversation there.

About reprocessing air, there is a way to do this with photosynthesizing bacteria provided that they can be engineered to utilize the wavelengths, which would be rather different (but has the pleasant side-effect of gradually increasing molecular oxygen levels), but it would be difficult due to the reduced gravity's effects on atmospheric mass and the amount of maintenance required to make the base self-sustaining.
The general relativistic effects upon mass would be too minimal to worry about, as such I think you mean weight.
Mass and weight, even after years.

A good choice for an initial attempt at terraforming Mars could be a probe deliberately contaminated with a mix of cold-resistant anaerobes and photosynthesizing, spore-forming strains.
I think that electrolyzing the rust and separating the iron from the oxygen would be one good way, providing iron for industry and having oxygen to sell to individuals or companies or (if altruistic enough) simply to be released directly into the atmosphere. The atmospheric pressure would need to increase from its current 5 to 8 millibars to about 80 millibars first, but once it reaches that level the process of increasing atmospheric pressure will become automatic as carbon dioxide and water sublimate and evaporate (as per Mars Society's info in How to live on Mars). Also, asteroids such as Vesta and ice from the rings of Saturn could be broken up and sent piecemeal in chunks that will erode in atmospheric entry of Mars and thus allow for more water to be added to the surface (as per Kim Stanley Robinson's Red Mars)
The partial pressure of the carbon dioxide in the atmosphere there seems to be higher than the partial pressure here, but what is needed is simply more gas. If a more earth-like atmosphere dominated by nitrogen was desired, I would suppose that a possible method of obtaining the nitrogen is by using the ammonia present on on various objects and having denitrifying bacteria (well-adapted to the lack of oxygen) process an artificially heated and hydrated sample of ammonia-rich matter. Of course, the temperature would have to be kept rather high, but the water produced by some varieties can help with the issue of obtaining water, although it would be more practical to purify a melted ice sample. Now of course, there is the problem of the dust storms. Perhaps, they will reduce in intensity once there is growth in the ground to bind the particles. To separate the iron from the oxygen, it might be possible to use bacteria that produce reducing agents in the presence of water, but what I do recall is that iron-processing bacteria seem to have a general tendency toward oxidizing iron. There is certainly a good point about industry and oxygen production.
On a related note, I wonder how long it will take for the first well-coordinated Dyson sphere (or approximation of a sphere) to develop. If it had large faces/sides, it could have interesting applications in literal climate control.

We wouldn't have to worry about leaving our world if 'we' would stop over-populating it.
