Probably cannot be done anyway. Mars has almost no magnetic field. This is probably why it lost most if it’s atmosphere, and cannot host much of a new one.

hey, i am allowed to dream

and besides, if Islam destroys Europe and USA, there won’t be much left worth living for on earth

a few space colonies might give us a future, chance(s) to defeat Islam (or leave it behind!) and build decent civilizations again

What gave you the first clue, Sherlock?

Terraforming is for TERRA - EARTH! Mars is not Earth. Different gravity, amount of sunlight, atmosphere, soil, water supply.

Using astronauts’ poop to fertilize your plants is going to get you killed.

As already stated without a magnetic field, the solar wind will blow the atmosphere away, as it has for millions of years. All this stuff is a liberal pipe dream.

A 1976 NASA report, "On the habitability of Mars: An approach to planetary ecosynthesis" (NASA NP-414), estimated tens of thousands of years would be needed to generate enough oxygen to make a breathable Martian atmosphere.

But even if the temperature could be increased and enough oxygen could somehow be produced, Martian gravity is not sufficiently strong to retain enough oxygen for a breathable atmosphere. And since Mars doesn't have a magnetic field like Earth, cosmic and solar radiation would attack and contribute to the destruction of any atmosphere that is generated.

Earth, with its 1 g gravititational force at the surface, and its magnetic field protecting the Earth's atmosphere can retain oxygen. Mars has only 38% the gravity of Earth.

All the libs are like, “If Obama were still president we’d be terraforming Mars. Remember all the funding he gave to alternative sources of energy.”

Idiocy, unless they have a solution to restart the magnetic field, ala “The Core”...

She’s dead Jim. No different than Earth, there’s nothing us little ol humans can do about it.

Who thought it was possible? Can we drag ice asteroids out of their orbits and toss them at Mars?

This is good start coming from NASA. Yep they are admitting that it is simply too hard for man to change the climate of a planet. Wait ...

A new home for Obama's muslim astronauts.

Interesting.

It is probably more valuable to find ways to generate limited atmospheres economically for enclosed spaces, as well as economical methods to construct such enclosed spaces - such as buildings, domes, and sealed off caverns.

That is the more pressing engineering question. Backward planning from the earliest possible human bases on Mars (possibly next decade, growing more likely the decade after), the chemical processes must be chosen, so that equipment and supplies can be calculated into the space and weight budget for transport.

Terraforming can wait until technology develops.

The ancient Martians were at war with the fifth planet for thousands of years. It was a low level war, but peace was never considered. The Martians developed a super weapon, powered by energy stored in the planet’s molten core. Mars fired the weapon, destroyed the fifth planet, the planetary debris forming the asteroid belt. On Mars, the core stopped circulated, its magnetic field disappeared. Within a few generations, solar winds had blown away the Martian atmosphere, and with it, the Martian Civilization.

Mars One's initial base concept - imported capsules with soil-bermed local enclosures.

Under Dome Agriculture/Aquaculture, with underground habitation and industry, to source more requirements locally.

Clearing dust from domes and solar panels will be needed

Elon Musk proposes that initial bases develop the essential infrastructure and services, that enable more and varied activities to move in over time.

A better be would be terraforming Venus.

This is for anyone who mentioned Mars' lack of a magnetic field, or for anyone else I thought might be interested. There's hope! Don't give up!

NASA proposes a magnetic shield to protect Mars' atmosphere

No mention that Mars’ core is not molten thus no magnetic field which is what the atmosphere would need to protect it from solar winds.

Benjamin Franklin paraphrase:

We gave Mars an atmosphere, if Mars can keep it.

I would question Mars’ ability to hold a stable earthlike atmosphere. Its size and mass make it the reason for what it is right now.

Terraforming. Sigh. It’s probably an old word, but when I hear it, I think of sci-fy movies. Makes me think that the lives and psyches of younger people coming up, revolve around improbable movies, t.v., and video games. I know that older generations are always shocked by the younger ones, but I don’t think there’s ever been a time, in American history, at least, when the next generation has been so lied to and indoctrinated. They honestly don’t know the truth, and they’ve sold so many lies, regarding so many topics, it’s frightening. I used to wonder how things could get so horrible as the book of Revelation describes. I don’t wonder any more. Pray without ceasing.
