I don't know that it's impossible, but you might get a Nobel Prize if you can figure out a way to do it

Well, since the cause is the solidified core and lack of rotation, theoretically reheating the core to melt it and shocking it to move and then throwing some asteroids to help the rotation can do it. The asteroid can also help raising the surface temperature and adding atmosphere. But theoretically only:)

From what I've read, it appears that the Martian soil is quite capable of supporting plant life.
It's the growing conditions that are a major problem

I seem to recall reading something similar, but I couldn't find any articles confirming Martian soil is good when I checked. Do you remember where you read that?

Only 15 more years to go. That's way too early for alzheimer! 1ey

Gasp.....I like how you think.

The issue here is that I dont know what it takes to re-liquefy a planet's core. I don't think we have tech that's potent enough to act on an entire planet at once.

Here's some quick info on Earth's magnetic core. We have a solid inner core, and a liquid outer core. If not for that liquid outer core, Earth would lose its magnetic field and, before long, its atmosphere as well. Then we'd be done for. Between the no-atmosphere killing all life, and no longer being protected from various types of dangerous radiation the Sun emits, mass extinction would happen on Earth in relatively short order.

I think the current scientific theory is that Mars once had a liquid core, too, but that it is now geologically "dead" because the core has solidified. That's why it has no magnetic field and no atmosphere to speak of.

If we are going to be able to artificially create an atmosphere on Mars, we might have to do so underground, where it (and we) can be shielded from the solar winds and the heavy-duty radiation that bombard the planet.

Actually it's more like Martian soil simulant based on available data such as from the rover, not the real soil from Mars. You may check an article titled "Can Plants Grow on Mars and the Moon: A Growth Experiment on Mars and Moon Soil Simulants" by Wamelink et al (2014):)

Hahahah thank you:D It's just some stuff going around in the other community, borderline fringe and scifi sometimes:)

Yep, that's the established theory for now, although there's still some thin atmosphere. I heard they'll send another mission named Insight to drill and check the core etc.

And if you had the technology and available energy to do that, it would probably be just as easy to blow it up (along with half the solar system) and build a Dyson sphere from the rubble

and then throwing some asteroids to help the rotation can do it.

Some of the orbiter imagery suggests that a large amount of sediment has been laid down within a geologically brief period, so that may have already happened

I have no problem with that logic

Nope, mega structure and planet cracker are much more advance since they involve space travel. Plus, losing half of the solar system may largely disturb the earth's revolution:) .

Yep, but those are long long time ago and not manipulated to increase the planet's rotation.
