TOP ASTRONOMER WARNS THAT ELON MUSK'S MARS PLANS ARE A DANGEROUS DELUSION “I DON’T THINK IT’S REALISTIC..."
PAUL MAROTTA VIA GETTY / FUTURISM
Mars Attack
SpaceX CEO Elon Musk has said he plans to put a million people on Mars
by 2050 — with his ex-girlfriend Grimes presumably being one of those colonizers.
But Martin Rees, respected astrophysicist and member of the Royal
Households of the United Kingdom under the lofty title of "Astronomer
Royal," is saying not so fast — and calling Musk's plans a "dangerous illusion."
He made his bold-face remarks for the House of Lords' podcast Lord Speaker’s Corner, as spotted by The Telegraph, in which he also called
Musk an "extraordinary figure” who has a "rather strange personality," alluding to Musk's increasingly erratic behavior.
"I don’t think it’s realistic and we’ve got to solve those problems here
on Earth," he said. "Dealing with climate change on Earth is a doddle compared to making Mars habitable. So I don’t think we should hold that
out as a long-term aim at all."
"I think there might be a few crazy pioneers living on Mars, just like
there are people living at the South Pole, although it’s far less hospitable than the South Pole," he said. "But the idea of mass
migration to avoid the Earth’s problems, which he and a few other space enthusiasts adopt, that, I think, is a dangerous illusion."
Hazy Future
Rees instead proposed that any human exploration of space should be
funded privately and not with public money, like the close collaboration between NASA and Musk's SpaceX, because governments "got to be very
safety conscious and that makes it very expensive," he said.
Instead, Rees proposed remote-controlled robots do the bulk of
exploration — and heavy lifting of building structures out in space — while "only people who really have a high appetite for risk should be
going into space, and they should be privately funded, not by the rest
of us."
NASA is already exploring commercial partners, including SpaceX, for
getting to Mars, which will undoubtably cost countless gobs of money.
These are practical points Rees has raised, because our bodies are just
not equipped to withstand longterm space travel due to the low gravity
and cosmic radiation, among other harmful factors.
And in a bigger sense, maybe he's right that we should fix up the
problems we've caused here on Earth before forging out to mess up
another planet.

Given that Mars radius is about 0.6 times that of the Earth and it have
about the same average density, it's mass is 0.6^3 that of the Earth, or 0.216 Earth mass. So, the surface gravity is 0.6 Earth's gravity and
it's escape velocity 0.36 that of the Earth.
The result ? Even with a magnetic field as strong as that of the Earth,
Mars would still have lost it's atmosphere, only at a slightly slower
pace. With a strong magnetic field, at best, Mars would barely have 10%
more atmosphere left than it currently have.
Living on Mars is worst than living at the summit of Mount Everest, IF
Mount Everest was relocated near one of the poles.

There is a huge corpus of material on it. Early material -- mostly
related to looking at the Cold War and nuclear deterrant -- tried to
argue that a rational agent would eventually end up co-operating for
things like Assured Mutual Destruction.

Jim, I'm going to 'assume' you are a U.S. of A.'ian because you used the word/abbreviation 'math'.
When you use the full word, do you say 'mathematic' or 'mathematics'??
Because, here in Australia, we tend to use the full word 'mathematics'
.... which then gets abbreviated to 'maths'. (note the 's' at the end of
both the full word AND the abbreviation.)
Saying 'math' just seems awkward ... but I guess it's what you're brought
up with.
-------------------------------- (my news reader doesn't insert > before quoted text)
In my frequent correspondence with Brits I use the Yank version to self identify where it's well understood, both where it isn't, like hood/bonnet
or a Snow Plow in the USA is a Gritter in the UK,
in suggesting used blade
wear edges as a cheap/free source of high carbon steel plate. I don't know
as many Anzac terms, or if the ones I do know are insulting. British
programs are common on Public TV here, the only Australian series I watched was Supernova.
The full word here is Mathematics. I might write Maths if the reader understands, or degrees C instead of F, the issue is suggesting suppliers whose website doesn't clearly say if they sell in Britain, so I make the US connection obvious. Shipping between the US, Canada and the UK can be problematic.
Sometimes I throw in a Latin, French, German, Greek or Russian (Maskirovka) word to see if anyone will complain.

LOL. You have mis-attributed what I wrote to Jim. Dont worry. We've
all done that. :)
I lived in the US for 10y but used "math" all my life anyway. People
have a problem with my accent because of my army brat upbringing. I
dont think we stayed in most places more than 2y and a lot of them
only 12m. Americans think I am South African or Dutch, Germans think
I am Danish, Norwegians tell me to "please! just speak English", and Australians think I am English.
The universe is very complicated. :)
No, "Snow plow" in USA is a snow plough in the UK.
A gritter is a truck which spreads grit on icy roads.,

Interesting.
I recall only recently (maybe 5+ years ago) noting the use of the
word "maths", usually in scientific literature, in place of "math".
Didn't think of it as a US versus rest of English speaking world
difference.
Just changing word spelling that happens for certain words from time
to time.
It's taken 60-70 years but I now dont vomit anytime someone says "dans" instead of "darns".
So there is allays hope! :)
