ONE GIANT LEAP FOR MANKIND Elon Musk to reveal next step in mission to build city on Mars
(Excerpt) Read more at thesun.co.uk ...
what about the fact mars has no real Van Allen Belt that you mention.
essentially people would be living on a dead rock blasted by radiation.
All musk wants is more taxpayers’ money to advance his schemes. The guy is quite a snake oil salesman.
Someone on this thread mentioned underground. That’s the only thing that would work.
I have a theory that the earths core runs at a different speed than the outer crust because of a meteor hit.
I can’t figure out any reason why the core would spin at a different rate.
So, if the crust moves at a different speed, then it may swing pack and forth like a garden gate door on springy hinges. It goes back and forth until the motion eventually dies out.
That would explain the magnetic poles reversing too. Along with occasional extinctions.
Love your visualization of the speed of core rotation, versus crust rotation, and how those two forces interplay. Science is advanced by such thinking and ‘what ifs’.
“The language you see here is alien.”
Heh. I actually remember seeing that Three Stooges movie at the base theater when I was a kid. Good times.
“They’re for kick starting life on that rock.”
“Kickstarting life” on a planet unsuitable for life seems like a fruitless quest to me, but whatever floats your boat, I guess.
““Kickstarting life” on a planet unsuitable for life seems like a fruitless quest to me...”
There are earthbound microbes and the like, which have evolved to live in environments even more hostile and extreme than that on Mars.
Scientists have dubbed them, ‘extremophiles’.
It’s been postulated that some strains could easily survive on Mars.
To sustain human life (which is what we're concerned about here, or nobody would be talking about Mars), we would need to grow actual edible food, not putz around with bacteria. Unless you've discovered an extremophile potato, they're not really relevant to the conversation are they?
I suppose if we could get bacteria to grow there they might begin changing the environment on Mars to make it more conducive to life, but they wouldn't give Mars a magnetic field, or move it's orbit closer to the Sun, and anything they could accomplish would be taking place on a geologic timescale, meaning it would still be irrelevant to us, and probably to all of our future descendants.
Well, thanks for coming to the point. I didn't understand that's what you were driving at before.
I completely agree with you about the need to grow our own food there. I'm pretty sure we've got the technology down pat to construct greenhouses with controlled environments sealed inside.
Seems to me, the biggest problem would be the simple logistics of shipping all of the components there. It would cost a tremendous amount of money, and take a very long time to get it all in place, given our slow propulsion technology. If I recall, it costs $10,000 a pound to get anything into space.
I'd almost prefer to slow down the Mars exploration timetable and concentrate efforts on building a better rocket ship. We need the capacity to lift greater payloads at a smaller cost. Secondly, we need to be able to move those payloads to their distant destinations at far greater speeds to make these projects more practical.
As to the extremophiles, why not? If that rock is dead, we may as well start seeding it as soon as we get there. It'll pay off in some long distant future.
“I didn’t understand that’s what you were driving at before.”
Well, that’s what happens when you reply to the last comment in a conversation without bothering to go back to see what the conversation was about.
Thank you, I don;t think I’ve ever heard any theory like that about inner-vs-out rotation.
It seems to me that a ball floating in friction-less space should all turn at the same time.
Why would the inner core still rotate at a different speed after billions of years?

You just chopped off a hand that was extended in friendship.
Alrighty then.
