Terraforming - the Moon vs. Mars vs. Venus
Monday, May 19, 2008
There's a discussion going on over at space.com about this very subject at the moment.
I'm on the same page on the subject as one poster who said:
Honestly, I think Venus would be the terraforming challenge I would like to work on. It seems like it would be easier to remove an abundance of greenhouse gases than transporting them.

Venus would not be as hard as people think. Hit venus with astroids and comets of H2 will increase it rotation. change it's axis if desired. H2 will change the CO2 in to carbon abd water. All that will be left is 4atm of N2 and this may not be bad. How much N2 is used by life to make protien?
I like Venus simply for the gravity nearly Earth's. The biggest problem would be getting it rotating at 20 to 30 hours. You could build "screens" in orbit, possibly around the equator, that would cool the atmosphere. As it's cooling, we might find out what that will condense out of the atmosphere, and find out just what we need to add to make it liveable, maybe adding some lichens, moss and ferns first to get some vegetation going, which might work on Mars as well.
