Mars Terraformed

"After terraforming , Mars would once again lose its capacity to support life. But 100 million years is a long time. In fact, Earth might not be habitable for much longer than that. As the sun continues to brighten, Earth will succumb to a runaway greenhouse effect. The oceans will evaporate, creating Venus- like conditions unsuitable for life. So our second planetary home might last almost as long as our first. " Christopher P. McKay , planetary scientist at NASA Ames Research Center, studying planetary atmospheres, astrobiology, and terraforming.

I like the part "No swimming before terraforming is complete" haha

[GregoryTheGrster]

After Mars, can we terraform Venus next, please?

[MrGamerman]

Life finds a way.... Magnetosphere or not. I think we're too rooted in our thought of what "Earth life" is, to even try to understand the possibilities we could achieve on Mars.

[francismeyrick]

great video. Nicely produced. To the naysayers, I would remind you the local bar patrons mercilessly ridiculed the Wright Brothers...

[ArcadeTetris]

before we can terraforms mars, 1st of all we need to terraform earth politics.

[joebonsaipoland]

Save our earth, why is everyone so fascinated about terraforming Mars?

[BFDT-]

Best visualization so far of an exploration, settlement, colonization and terraforming of Mars yet!

Tritium, the fuel for fusion bomb, is radioactive but decays quite quickly (a half-life of 12.6 years).Present Martian atmosphere is only about 0.6% of Earth's (rest 80%-90% is frozen) so we can't loose a lot of it. All what is needed for bacteria farms is plastic, which future colonists can produce on Mars (from Martian resources). The process for methane factories is a Sabatier reactor: CO2 + H2 → CH4 + 2 H2O
An alternate method uses RWGS with electrolysis: 3 CO2 + 6 H2 → CH4 + 4 H2O + 2 CO

Why Mars Couldn't Give Rise to Civilization ?

While MrAnderson already responded about the atmosphere of Mars being depleted over the next million year after it has been terraformed, one thing to remember is that regardless of the magnetosphere, you can keep an atmosphere and lose it. Meaning, Earth is losing atmosphere at the same rate as Mars and Venus yet we have a strong magnetosphere. Also, Venus has no magnetosphere yet has an atmosphere 100 times thicker than Earths.

[MrAndersohn]

You can't compare Mars and Earth, Mars has a big difference : it has a lot of frozen CO2, so we need just to start global warming and then :" its frozen soil would thaw enough to release carbon dioxide, and more carbon in the atmosphere would further accelerate the greenhouse effect. Mars's frozen underground water supply would melt and flow back into ancient riverbeds. And when the water reaches Martian soil, it would break down latent peroxides, releasing oxygen into the atmosphere".

As long as no jihad jerk smuggles in mosquitos i'd move there in a heartbeat..

1) Automatic farms can be energized by sun rays.Whole farm could look just like greenhouse, trapping heat for bacteria. University of Florida researchers have discovered that some Earth bacteria can live under the same low pressure conditions found on Mars. Of course all this methods are really "flies on an elephant" and before Mars colonization we can't start effective terraforming. And nobody says it will happen tomorrow, but it's possible and it will inevitably happen after colonization .

Excellent, particularly for those who have read and enjoyed the Mars Trilogy

[MrAndersohn]

1)Mars is smaller than Earth 1.88 times 2) "As Mars warms, its frozen underground water supply would melt and flow back into ancient riverbeds.And when the water reaches Martian soil, it would break down latent peroxides, releasing oxygen into the atmosphere" 3) "Zubrin says, humans could walk around without supplemental oxygen within 1000 years. He predicts that we'll come up with other ways to speed up our settlement of Mars, such as genetically engineered plants that photosynthesize faster."

JIC you didn't know the translation got lost when Neil said the famous phrase, "one small step for A man, one giant leap for mankind." Makes more sense.

[MrAndersohn]

2) To speed up process (in future), we could use fusion bombs to melt polar caps. As it happens, it will trigger chain reaction and Mars will start heating itself, when temperature and pressure rises all this ammonia and methane producing bacteria will be able to live outside farms. Orbital mirrors + CF4 factories will speed up process even more. All these are not beyond out technology, the only question isn't "will it happen?", rather "when will it happen ?"

[CrabbyO]

That's a good point. But then, having a 30ft. wave crashing down on you would only FEEL like a 10ft. wave.

[blindandwatching]

Earth has a relatively weak magnetosphere but its strong enough to keep the deflect charged particles from the sun. The problem is that building an atmosphere will be compromised by the solar wind leaching away the thin atmosphere in the beginning. That along with the weak gravity is a big handicap to start off with.

[Roadsization]

this may work if we worked hard for 10 years on mars
