2012 Sun storm to hit with 'force of 100m bombs'


Recommended Posts

solar storm is relatively safe to the earth environment, it is just a spectacular aurora show

however, it can be disastrous to power grids and electronic devices, because it is a huge emp blast on a global scale, which can wipe out the electronic infrastructures

in the 19th century, theres no far-fetching power grids and electronic infrastructures like today; while there wont be a doomsday scenario which kills all human, but if the solar maximum storm hits earth a full force, it can create havoc on human society when the electronics fail

Very true, but there will likely be a huge number of deaths related to it. Think about the fact that nearly every form of transportation relies on electronics. Airplanes, cars, etc. will suddenly fail. If people are flying or driving when the EMP hits, it could very easily cause LOTS of crashes. A solar storm similar to the one in 1859 would cause MASSIVE damage to our global economy and infrastructure. Back then, the worst thing that happened was a bunch of shorted-out telegraph lines.

Events like this are rare, and probably won't happen during our lifetimes. It's nothing for the average person to worry about since you can't really plan for it, but it's something we should take precautions for since it could happen, however unlikely. The government invested something like $100 million to protect our electronic infrastructure from such an event. The military is more prepared than anyone else since much of their equipment is already protected against EMPs. I'd also be surprised if airplanes aren't already protected.

Yawn, if this scare mongering is anything like the Y2K Bug that was gonna wipe out the global economy ill be sat on my lawn with a beer in my hand with a front row seat to apocalypse.

If I could rep you for this comment, I would (Y)

If we're all going down, i'll be on my lawn drinking a beer too.

Okay IF it happens, then so what? Just launch new satellites. I'm sure they'll have some on standby.

I'm not to worried. If they are, then spend the millions now and get it ready to roll for then, eh? :)

yeah like human-created virtual/paper money can create resources :rofl:

Heh, if it DOES happen there wont be any electronics working to "Just launch new satellites". Think massive power outage, shorted out electronics, no computer, limited communication, NO GPS.

Since when did a shuttlecraft need to launch using electronic power? - Okay that was a semi joke, I realise they use extensive computer systems.

But who was it that just said that most of NASA's stuff is EMP shielded? I mean, seriously, they've got it covered.

Don't worry, they'll be right in 2012. I'm just more worried about my computer! :p

An iPod shuffle probably has more processing power than the Space Shuttle's onboard computer.

The article is just as ignorant as some of you posters. First and foremost, the article fails to mention the fact that earth is protected with a magnetic force field or "shield" that repels all of these sun flares. The magnetic field is weakest at the north and south poles.

The picture above is what a solar flare looks like when it hits the poles. The solar flares make its way through the magnetic shield at these weak points, and that's why the beautiful image above appears to have a "greenish" sky. The only way a massive solar flare could affect our planet and potentially knock out electrical devices is if this shield fails. The shield is generated at the center of the earth. Unless earth stops rotating around its core, this is impossible. Another way for a flare to hit earth, is if the magnetic field surrounding earth flips (this has happened before, hundreds of thousands of years ago - there is no explanation of why this happens, but NASA has confirmed that it appears to be part of a cycle, and is guaranteed to happen again; they just don't know when). This means earth's strongest magnetic pull will be at the south, at which point compasses will no longer point to the north - but to the south instead. The transition "flip" of our magnetic field may last up to a few days, in which case earth will no longer be protected from these sun flares. If there was a solar flare headed for earth during this transition period, all electrical devices will be toast. Guaranteed.

I believe he is right, and its one of the reasons the shuttles are being retired. They are old, and are still using a lot of tech from the era they were built in.

Good point too.

But we're talking about launching a satellite, not a shuttle, surely they work on different technology...

Those Russians have some advanced stuff you know!

The solar wind consists of plasma; atoms so hot that they lose their ability to even hold on to their electrons and become ionized. Charged particles are shot off the sun's corona and out into space. If the mass ejection is strong enough it will distort our magnetic field so much that inhabitants of texas will be able to see the aurora borealis, this means all those charged particles are not harmlessly flying in at the caps but right into our infrastructure and grids. It is these charged particles that travel into our unprotected power grids and short them out.

Our magnetic field can only withstand a specific strength of the suns mass ejections.

    • According to Microsoft, Cause: One of the drivers controlling the device notified the operating system that the device failed in some manner.   https://support.microsoft.com/en-us/topic/error-codes-in-device-manager-in-windows-524e9e89-4dee-8883-0afa-6bca0456324e
    • This looks awesome, I will request access via Steam later this afternoon!
    • Personally, I’ve found that it’s usually worth investing in the infrastructure you don’t want to replace later, especially cabling. Running Cat6A (or better, depending on your needs) during an upgrade is relatively inexpensive compared to having to re-cable a few years down the road. For switches I try to balance current specs with realistic growth. If my budget allows it Ill choose switches with higher uplink speeds which leaves room for expanding later on, but I don’t necessarily overspend on access ports if the endpoints won’t benefit from them anytime soon. One lesson I’ve learned is that planning for scalability pays off. It’s much easier to add devices, VLANs, or higher-bandwidth workloads when your network infrastructure already supports it than to replace hardware later.  What is your budget like?
    • I hate the term, "future-proof." We saw it back in the 90's / 2000's, if not before. You cannot future-proof anything, since there is no definition of how far into the future you plan on prepping for. Best idea is to tell us what you currently have and what its use is at the moment, and we can then offer ideas about some areas that might need an upgrade and other areas that can be left alone.
    • I can agree that it is being used in a small capacity. I worked for a company where their engineers still used XP, and when asked why it was because their sensor software wasn't compatible with newer operating systems and the software was discontinued so they couldn't upgrade the software. Given that the sensors were still in use by companies, they had to continue using XP to support the sensor, otherwise the price to the company would have gone into the millions or billions. Our response was simple: Ok, you can keep the XP machine. But we're removing it from the network. "But then it can't access the Internet or folder shares!" Yup, kinda the point. If someone wants to continue using an unsecure OS they can do, I have no problem with that. But it should be isolated. Simple. I had a fight with a guy in the engineering department for weeks before he finally relented. But we digress.   What do I plan on doing to commemorate the anniversary? Nothing. I have fond memories of the OS, but at the end of the day it's just an OS. If I had some time I might see if I could install it on my Raspberry Pi for a laugh. But my reflex memory with today's OS ideas would probably get me frustrated and I'd uninstall it after 5 mins.
