19. It's about trapping water vapor.

Venus doesn't have a magnetosphere either, however it also doesn't really have any moisture in the atmosphere from the limited probings we've done. Without the ability to establish a water cycle, which requires atmospheric water vapor and hydrogen and oxygen, we can't really call it terraformed.

The issue with Mars is that it does have a magnetosphere, it's simply fragmented, this creates pockets of gasses that are then blown away into deep space.

But hey, move all of the asteroid belt along with both martian moons to mars, and it might gain enough mass to restart the core...

No magnetic field, so background radiation from space is much higher than on earth. struggle4progress May 2013 #4

Tons of issues; no doubt. Warren DeMontague May 2013 #8

terraforming mars isn't really feasible IMO. Sirveri May 2013 #9

Feasible next week? No, absolutely not. Warren DeMontague May 2013 #10

Restarting the dead core of a planet? Sure, it's "possible". Sirveri May 2013 #11
