Mars and Venus, those seemingly contrasting planets of self-help book fame, have more in common than you might think. Two nearly identical spacecraft around Mars and Venus have compared the two worlds' atmospheres and found them to be surprisingly similar. The ESA's Mars Express and Venus Express are currently in orbit around the planets taking measurements of their atmospheres as they interact with solar radiation. The data show that charged particles from the gas layers around both planets are being scavenged by solar wind and storms. "Mars and Venus are very different planets," said David Brain, a planetary scientist at the University of California, Berkeley, and a supporting investigator for Venus Express. "Venus's atmosphere is very thick, dry and hot, and Mars's atmosphere is very thin and cold. And yet the same processes are happening on both planets." Full Article

To be honest I never really thought about it in this regard. But I wonder if the moon has any reason for it...and if so, I wonder if some place like Saturn which has moons as well could possible be a more interesting planet to try and cloriform and perhaps colognize.

I'm actually working on a research paper about the colonization of Venus versus that of Mars, and I had stumbled across the fact that neither of them have magnetic fields. The fact that Mars's is so thin already and still dropping would cause problems.
And I don't think the moon has much to do with it, actually. Having an active core is what creates the magnetic field. From what I've read, Mars is rather dormant, and the lack of liquid water on Venus has left the rock horribly dry.... Basically, it doesn't have a tectonic cycle like Earth does to keep everything moving under there.
I'll have to find some quotes from my research to back that up.

This to me seems true thought reading books on planets, Venus is very hot and moyster, while Mars is thin and cold.
Thought I always thought that Mars was always hot? Isnt the top of Mars the coldest part?
Here's another question. I thought scientist has always said that Venus and Earth are smiliar?
