Just a passing reference in the article that would seem, on the surface, to be utterly ridiculous. An entire planet's iron core was "somehow undone"? What exactly might that geophysical or chemical process might be? Did the strong force just up and decide to retire?
Quaid, start the Reactor!
It’s a shame Mars is so small compared with Earth and Venus.
I think the standard view is that Mars’ core cooled down and largely solidified, thus cutting off its magnetic field (which could then no longer protect the planet’s atmosphere from the solar wind and cosmic rays). Hasn’t happened on Earth yet, because Earth is quite a bit larger and its core is still molten.
Who does the guy from NASA think “we” is?
One word that says so much....
Whatever you do, please don’t let Muslims go to Mars. Keep it peaceful.
Didn’t they address this issue in the movie Total Recall already (including the funny faces you make when you run out of air)?
It’s amazing to me though that an artificial magnetic field at L1 could protect the planet 600 thousand miles away!
We = humans. He’s talking about humans.
A$$holes. The process by which Mars lost its atmosphere has not stopped. It is still there. The gases that you plan to put on Mars’ surface will go the way of the previous gases. This should be obvious.
So, pump oxygen/carbon dioxide/nitrogen onto Mars’ surface. Watch it go into space. Wheeeee!
Enough of this crap. The reason why they want to put humans on another planet is to start civilization all over again, this time WITHOUT RELIGION (except for *slam, which will be given privileged status.)
I enjoy sci-fy articles and creative ideas. But they are funny to us now with technology we currently have.
First, we only need to create a magnetic field to surround Mars that is stronger than Earth’s. And we cannot use Mars’ iron core for this because it’s already dead. We can use inflatable bags that will stay in a synchronous orbit between the sun and Mars at a specific distance from the red planet. Sounds easy.
What in the world is stopping us? LOL.
You must not have read the article.
Not much. We have satellites hovering at Earth's L1 right now.
I’ve read that it’s radioactive decay that keeps earth’s core hot.
Ah—the humans all united with one agenda and one goal—those humans.... :-(
Space stations are the answer. I’ll take a good’ol death star any day over mars.
Even simpler, just melt the core of Mars so that it becomes molten again!
What would be the mass of a real death star? All metal the size of a small moon? Would it create it's own gravity. Where would we get all the metal that would be needed? It it came from earth, would that affect the mass of our own planet, gravity, rotation, etc.? I've had these questions since I saw Star Wars for the first time. LOL
