Yes, Mars is smaller than Earth, but still, if Humans were to try to terraform it, I think it would actually take longer then the natural process. Initial stages of terraforming Mars could take several decades or centuries.

How long would it take to terraform Mars or Venus? 8 years ago. Mars’ atmospheric pressure also ranges from 0.4 – 0.87 kPa, which is the equivalent of about 1% of Earth’s at sea level. Forget about that vacation home on Mars, at least for now. Then compute the matter and energy needed to get there. It's likely to take hundreds of years, as you've got to change the composition of the atmosphere of a whole planet. But there is a huge amount to go wrong. How long it would take for all the radiation to disperse, though, and what effect it would have on Mars as a whole, isn’t clear. You need got to undo the reasons that Mars doesn't have an atmosphere already, which is that it doesn't have a magnetic field.

Answer Save. The intrinsic value of these species would give us some reason to refrain from terraforming. Jakosky and Edwards used data from the various rovers and spacecraft observing and studying Mars from the past 20 years to essentially take an inventory of the planet's stored CO2. The solar wind has gone past, but there's no magnetic field to deflect it, so much of the atmosphere has been lost. The more interesting philosophical question is whether there are any reasons to resist terraforming if it turns out that Mars is lifeless. You need got to undo the reasons that Mars doesn't have an atmosphere already, which is that it doesn't have a magnetic field. Terraforming the entire planet into an Earth-like habitat would have to be done over several millennia. Remnant | January 2, 2017 @EVolution (OP, January 2, 2017) << How long before terraforming Mars in the best scenario? I believe terraforming it can be done with current technology be releasing CO2 into the atmosphere (which is what we do best).

To answer that you first need to determine what your final conditions on the terraformed object will be. How long will it take to terraform Mars? I was wondering how long it will take to terraform Mars on a tight schedule to expand humanity and export wars to terrirories conquests on orther planets. Some people say it would at least take a century for the atmosphere to develop.

I think we need to be able to live on another planet in case something happens to Earth. If you would to try to terraform Mars, it would take a long, long time. The Earth was being pounded with meteorites almost, if … 7 Answers. The solar wind has gone past, but there's no magnetic field to deflect it, so much of the atmosphere has been lost. Look how long it took Earth. It's likely to take hundreds of years, as you've got to change the composition of the atmosphere of a whole planet.

NASA said there isn't enough carbon dioxide on Mars to terraform the planet, according to a study released Monday. I think with Conifers it would only take 40 years at the max. I was wondering how long it will take to terraform Mars on a tight schedule to expand humanity and export wars to terrirories conquests on orther planets.
