Elon Musk Announces Plan to Control Climate by Surrounding Earth in Adjustable Satellites

It’s not really a new idea.
Yes, but there are far easier and cheaper ways to go. Dude must have just read about using things from space to control sunlight input and thought he's such a genius surely he can figure it out. I guess he skipped over all the debunking that such ideas get.
And crucially, once we jump on the geoengineering train, we better not stop. It will only slow things and buy more time, but if we stop after beginning, the spike will be catastrophic (probably, there's still so much we learn, but it won't be a solution). But we will go that route, because economic health is far more important than anything else, and never plateaus by its very nature. There must be growth, or it all crashes down.
Stop polluting and plant trees.
Rocketing giant mirrors is not only stupid but also temporary.
You are not wrong, though everything is temporary. That is not a reason to not try and develop new technologies and methods to solve problems.
The error is in the focus; we have some tested and tried methods we should apply before we work on the far future stuff, indeed.
That’s your logic? Goddamn.
First of all, define “being”.
Then define “real”.
And lastly, define “it”.
It seems like you might have skipped a few steps.
I will say it again:
Musk is not an engineer. E.g. he has not played Kerbel Space Program.
He demonstrably does not understand the tyranny of the rocket equation, and how obscenely uneconomical getting anything to, and doing anything in, space is: en.wikipedia.org/…/Tsiolkovsky_rocket_equation
Geoengineering is something worth seriously discussing (and TBH I hope he draws attention to it), but this is not the way. Not with the trajectory of launch tech we have.
I hate this accusation. It is demonstrably false and reeks of a “No True Scotsman” fallacy. He knows a lot more about rockets than you… or at least he did during the Falcon 9 days. Watch any technical interview with him from ~5 years ago and he can very clearly explain why they made the engineering decisions they did.
That being said, his involvement in the development has obviously stopped because he can barely put together a coherent sentence about Starship these days.
Just because he’s the most dangerous fascist on the planet right now doesn’t automatically mean he’s never been an engineer.
If you said this a decade ago, sure. But at this point there have been so many examples of musk misunderstanding fundamental concepts in areas that he likes to pretend to be an expert on that he doesn’t get benefit of the doubt. The dude is only good at being rich and bullying people. He has no engineering acumen, be it software, vehicles, or spacecraft.
He’s good at repeating things that smart people have told him, but as soon as he is asked to think rather than simply regurgitate, he’s useless.
I think that’s essentially the same thing I said, just a slightly different timeline. You can see the man’s understanding of rockets deteriorating over the years just by comparing the technical interviews he’s done against each other.
We have overwhelming evidence of this documented on YouTube for everyone to see.
Eh, maybe that’s fair. Especially this:
doesn’t automatically mean he’s never been an engineer.
Maybe he was quite knowledgeable… On the other hand, I thought its old Mars Colonization talk was bonkers too. I can’t remember what year it started, but it sounded like he had little understanding of the impracticality.
He still is involved with engineering things, people just want to think he’s not so they can think less of him.
E.g with Starship it was his decision (that he had to convince everyone on) to use stainless steel for Starship. If I recall correctly, his current focus is on the raptor engine.
he has not played Kerbel Space Program.
“Kerbal”
That’s just the drugs talking.
Don’t listen to old men on drugs. No good will come of it.
Emphasis on “tiny” adjustments, per the article. I don’t think Elmo comprehends just how much surface area is going to be required to make any measurable let alone meaningful impact, nor the cost of hefting all of that mass up there and keeping it there.
This whole crackhead idea is completely infeasible. But he probably hopes it’ll help him scam the government out of a bunch of money trying (and failing), while wasting vast amounts of rocket fuel.
Well, two things about that.
One, the L1 Lagrange point between the Earth and Sun is further out than the orbit of the moon. Even without doing any math, just a cursory observation of how shadows work will illustrate that, given that the moon itself can just barely cover the disc of the sun from where it is, any such object placed there would need to have a diameter larger than that of the moon in order to completely block the sun’s light. Or some appreciable and nontrivial fraction of the diameter of the moon if you only want to block part of the sun’s light. Lofting something that massive up there and more importantly keeping it there given that it’d also be well within the gravitational influence of the moon would be quite the challenge. (“Quite the challenge,” by the way, is rocket scientist talk for, “This is complete science fiction, and whoever suggested it is insane.”)
Point two is that the Deep Space Climate Observatory is currently already parked there.
any such object placed there would need to have a diameter larger than that of the moon
Well that’s kind of my point, that’s still a lot smaller than what Elon is suggesting. Elon suggested a sphere with a diameter larger than the earth, if the alternative is a disk larger than the moon, well that actually seems like a much better deal. Also, assuming a disk and a sphere have an equal diameter, the sphere has 4 times the surface area, so that’s not a trivial difference.
Lofting something that massive up there and more importantly keeping it there given that it’d also be well within the gravitational influence of the moon would be quite the challenge.
That’s interesting. Yeah that could be a challenge. Given the size of the thing, it seems like the obvious thing would be to utilize solar wind for maneuvering, as it’s already essentially a solar sail.
The Japanese space agency tested a solar sail in orbit with a novel steering system, rather than changing shape, it used something much like LCD cells to shutter individual quadrants of the sail. Something like that could potentially work.
Point two is that the Deep Space Climate Observatory is currently already parked there.
Yeah, that’s a good point. Although if you were actually building something this big out there, you would probably build in some capacity for probes to dock to it. This is a huge installation after all, a facility more than a probe. Or just add on a module that duplicates the capabilities of the deep space climate observatory. I mean once you’re constructing something this massive, that additional cost has gotta be a drop in the bucket, right?
You wouldn’t be blocking all of the suns light. That’d kill us. Blocking 2% would be a noticeable “fix”. It’s been a thought out on paper project for decades. It’s “possible” in the strictest sense, but would take something (or many smaller somethings) the size of most of South America to do. It would take thousands of launches to a destination around 800,000 miles away, and then it would also all have to be able to adjust for orbital changes because the lagrange point isn’t a stable orbit.
We just need another massive once a millennium volcano eruption. Throw the world into chaos and starve half the population to death while the earth is half covered in atmospheric ash for a year. The slow Thanos snap.
the lagrange point isn’t a stable orbit.
That’s totally true, but to be fair, it’s still more stable and requires less maneuvering than low earth orbit. So if we’re comparing the two orbits…

I gotta be honest, that sounds like a less-than-optional solution.
Lol. Thanks.
Low earth orbit is consistently unsstable but the drag and gravity is pretty consistent so you’re guaranteed to have to consistently adjust away from earth and speed up, or go the starlink route and just plan on launching a satellite replacement every 5 years(they do still have thrusters and adjust to stay in the right areas for their lifespan).
The lagrange point actually has a wobble to it. Due to solar radiation and gravity from other planets as they move around, so that sweet little perfect spot of neutral gravity moves around in distance between the sun and the earth all the time.
We’d probably have an easier time covering like 5% of our planet in mirrors spread out all over the place. That would cool the planet down by about 2c. Good luck keeping them all clean.
