[edit] Questions to answer

I don't know where to direct these questions, but the answers might be interesting to add to the article if someone wants to research them. Chadlupkes 19:51, 24 May 2006 (UTC)

• How much effect does the size of Mars have on the density of the atmosphere? If we did the work to increase the atmosphere, how much would it lose by simply not being able to hold the gasses on the surface? Now, given the density difference between Venus and Earth, perhaps some gases could be more able to increase concentrations than others. I know that some gases like Helium and Hydrogen have the ability to escape our own atmosphere, so at least Hydrogen would need to be combined with Oxygen in water molecules to be able to make them heavy enough.

• There were some tests done in the laboratory here on Earth to see what kind of terrestial life form would be able to survive and thrive in that type of environment. Is there any information in Wikipedia about those studies?

It's not only Venus that has a higher atmospheric pressure than Earth; Titan also has a higher atmospheric pressure than Earth, despite having a surface gravity less than Mars's. I have an equation in one of my books for the (simplified) halflife of an atmospheric gas based on molecular weight and surface gravity; I'll find that. Oxygen and nitrogen have much longer persistence times, being in diatomic gas form, than water vapor, but the persistence time for any gas is long enough that the required replacement rate to maintain a steady state would be miniscule compared to the rate at which it would have to be added in the first place for a reasonable terraforming program. - Reaverdrop (talk/nl/wp:space) 20:01, 24 May 2006 (UTC)

[edit] Next section: Adding Life

I think the next section we should add to this article is one about what it would take to add life to the Martian environment. But the only thing that I've seen on the subject is in Sci-Fi. Who has some true research done on this subject? Chadlupkes 19:55, 24 May 2006 (UTC)

[edit] Pictures

Do we need three "artist's conceptions" of what a terraformed Mars might look like? I've removed the top one, as it's the widest and most obtrusive. ▫ UrbaneLegend ^talk 13:16, 6 July 2006 (UTC)

[edit] ReDirect/Merge from Colonization of Mars?

Do we really ned 2 distinct articles, namely Teraforming of Mars and Colonization of Mars? It's not like colonization is likely to happen without teraforming or parateraforming.

The 2 seem rather duplicative.

• I think having two articles linking to eachother as they are now is better than a single article for two reasons. First, both are vast subjects that could easily be large pages in and of themselves. Second, human colonization would be possible without terraforming, not on the scale of millions but hundreds or thousands. --AndrewBuck 15:39, 23 November 2006 (UTC)

If millions of Canadians can thrive during the local winter in their underground cities I don't see why millions of Martians couldn't do the same year-'round. :) It's also handy having separate articles from an organizational standpoint too, since with things as they are now we can have "see main article at" links in both the colonization of Mars and Terraforming articles, neither of which has significantly more "claim" to the subject than the other.

[edit] {{originalresearch}}

I've tagged this article with {{originalresearch}} due to the citations needed on the processes involved in terraforming and methods that could be used. 1ne 05:28, 1 October 2006 (UTC)
