Default Terraforming

Any really fascinated by the idea and Science behind Terra forming a planet.

Read lots of books but recently they had a special about terraforming Mars however to my understanding Mars does not have a magnetic field making the feasibility of it unlikely.

I am no astrophysics dude, but I was under the impression that if a celestial body had some gravitational pull, it had a magnetic field. It is possible that the magnetic field is not strong enough to hold any atsmosphere that is conducive to Terraform? Please educate the masses who are curious...meaning me.

Terraforming - Wikipedia, the free encyclopedia
I love Wikipedia for this reason.
Its a cool concept that probably none of us will see in our life time.

I don't like Wikipedia for the misinformation it has proven to circulate on various topics. Oh well, it is what it is.

Mars has 1/3 the gravity of earth, thats what makes it loose its atmosphere very slowly and i mean very slowly, mars does have a magnetic field due to its core that is almost the same as earths but has not been active for a long time.
they said it is possible to make a atmosphere for mars but it would loses it over a few hundred thousand years cuz the core no longer works and people born on mars would not be able to just land on earth and walk around due to the gravity diff, they would have to get use to earths much greater gravity. No matter how much we warm up mars to make it livable the core no longer makes the heat to keep the planet warm so it will return to a cold dry desert.

(im no expert but now i have free time iv been studying their plans on terraforming mars the past few months) :-D

The question of the magnetic field of Mars has been in question for decades. Here are some results of the Mars Global Surveyor project currently in progress:

* Mars does not presently have a global magnetic field but had one early in its life, similar to that of Earth. However, Mars does have very strong crustal magnetic fields, more than 30 times stronger than those of Earth.
* Developed a detailed map of the magnetic fields of crustal sources.
* The absence of magnetization in large impact basins allowed for the first time to establish the time of cessation of the Martian dynamo, more than 3.5 billion years ago.
* The absence of a global magnetic field for billions of years has contributed to the erosion of Mars atmosphere by the solar wind and the loss of water.
* Established a correlation of the horizontal component of the magnetic field with upstream solar wind dynamic pressure.

So, to Terraform Mars, we'd need UV resistant plants. But there's no guarantee that any atmosphere enhancing would occur due to the lack of the global magnetic field needed to protect any atmospheric enhancements from the solar winds (bolded statement above).

Did anyone else immediately think about the impact of this fact on boobs, or is it just me?
