I wonder if 500 years is a reasonable prediction for how long it would take for cockroaches to evolve into ghetto cavemen? I guess DARPA will be looking into it.

my immediate thought after reading the title was "...incredibly racist?"

I'm more concerned about the idea of "repairing" damaged environments here on Earth. Just exactly who is going to decide what needs repairing?
Let alone taking an inhospitable Earthly environment and re-engineering it. ( Recall the quote from the late DeForest Kelly's Dr. McCoy "I know engineers, they looove to change things!" )
No I don't think they should test any of those processes anywhere near Earth, Mars might be a wee bit too close even.

I'm always psyched about these type of things.
Quote: | DARPA would need to engineer plants to grow on Mars to make the planet's atmosphere hospitable for human life. |
The question is how would we go about creating an atmosphere which wouldn't be whisked away by cosmic radiation, nor flow out into space due to there being so little atmosphere. I wouldn't be surprised if someone has already estimated how long this would take to make and it would take like some hundreds of millions of years
Credits to DARPA and other governmental agencies which are holding competitions and giving out grants to try to incentivize such far reaching questions within the civilian population.

The US will repair the parts of the end it doesn't currently own after they get there hunter killers autonomous and cheap.

Probably not that long. They aren't hoping to have this happen like just naturally on it's own with no human interaction at all. They're engineering it and probably causing things to happen at pace that's ridiculously beyond what it would ever just be on it's own in the wild.
Just thinking of the world in 0 AD vs 2015 AD makes me think it's super unlikely it will take humans a million years to do anything. Let alone hundreds of millions.

This is easily the number one most ignored problem of Mars colonization: the planet is dead. The technical means of founding an atmosphere don't mean jack crap without a vital magnetosphere; if you don't believe me, just look at stillborn Venus: essentially earth's twin, but without a magnetic field, evaporated water leaves the world a little at a time and the early atmosphere is never absorbed, leaving little more than a burning hellhole under a billion-ton blanket.

Darn it, I was going to mention that. A major reason life could happen on Earth is because Earth is the only terrestrial body in the Solar System with a magnetic field strong enough to deflect these harmful things away from the surface.
It is feasible to colonize on one of Jupiter's Galilean moons though, in terms of magnetic fields, using Jupiter's magnetic field as a shield. (Titan leaves Saturn's magnetic field when it's closest to the Sun.)

You don't think areas hit by natural disasters should be repaired?
(Conservationalism is all about ecological repair work--while it's true that natural processes can drive species into extinction and change climates, I think that humans have done a lot of damage to the planet and that humans must also take responsibility to undo that damage.)

Yeah. I was referring to how long it would take if humans introduce the right "ingredients", then let things occur naturally, and make up a way so that the atmosphere doesn't leave the planet. I don't know how long it would take to make an inhabitable atmosphere under those conditions.

I'd suggest encapsulating the planet with glass and make it into a planetary "snow globe". But this is more science fiction on my part.

45 years since we've landed on the Moon and we still haven't gotten to Mars. You'd think that in that time period we'd have finally gotten the technology and money we need to land on Mars.

It's far, far cheaper to send unmanned probes, and they're not that much less effective than having a human on the ground.

Yeah, that sounds like a fool-proof plan. What could possibly go wrong?

ikr? its about as genius as making dinosaurs as smart as humans and giving it a shit ton of new features never before seen in a single organism. Wont the general populace be thrilled?

They probably aren't talking about making immortal clones of Shaq and more along the lines of micro organisms like bacteria or something.

You need a material at least a thousand times stronger than steel to encapsulate a planet as large as Mars without the shell collapsing, let alone finding enough of this material to do so.

The other thing is that the Space Race that defined the third quarter of the 20th century was the Americans and the Soviets trying to outdo each other. Without a rival, there isn't much drive.
