Re: Time Scale

Hello,

When discussing terraforming, I hear that the probable time scale by which a potential process would move looks to be on the scale of many human lifetimes. Considering that Earth's atmosphere had changed into the present oxygen/nitrogen mix over the course of millions of years, is it even possible that any potential terraforming program would show results after a few millennia or even a few centuries? I mean, it's obviously a very long term science project. Although, considering that human industrial activity on Earth has demonstrably altered the atmosphere over the course of perhaps three hundred years.

Cordially,



EarthWolf

Re: Time Scale

To fully complete the process, enough oxygen to breathe without an oxygen tank, is somewhere in the 800 to 1,000 year area.

To have enough atmospheric pressure so you can walk around without a pressure suit is around 50 years.

Re: Time Scale

Hello,

Hmmm, interesting. But, how long would it be before the atmospheric pressure and ozone layer be improved to acceptable levels?

Cordially,

Re: Time Scale

The unknown technology which will leapfrog long predictions is the self replicating robot. If perfected within this century, the robots could turn Mars into one large shopping mall, cave, greenhouse complex. The speed of the transformation will be energy limited.
