Approaching Solar Storm Forces ISS to Take Cover 118

Posted by samzenpus from the here-comes-the-sun dept.
vichyschwa writes "A Coronal Mass Ejection resulting from an X3 Solar Flare earlier today is forcing the ISS and Shuttle astronauts to take cover and may result in communication disruptions. Last week, the same sunspot generated what astronomers described as a rarely imaged solar tsunami. The activity began with an X9 flare Dec. 5. According to Spaceweather.com, "satellites may experience some glitches and reboots, but astronauts are in no danger." However, the astronauts were ordered to a protective area of the space station as a precaution."

    I was confused by this, so I looked it up.

    From the Wikipedia article on Solar Flares: http://en.wikipedia.org/wiki/Solar_Flare [wikipedia.org]

    Solar flares are classified as A, B, C, M or X according to the peak flux (in watts per square meter, W/m2) of 100 to 800 picometer [wikipedia.org] X-rays [wikipedia.org] near Earth, as measured on the GOES [wikipedia.org] spacecraft. Each class has a peak flux ten times greater than the preceding one, with X class flares having a peak flux of order 10-4 W/m2. Within a class there is a linear scale from 1 to 9, so an X2 flare is twice as powerful as an X1 flare, and is four times more powerful than an M5 flare. The more powerful M and X class flares are often associated with a variety of effects on the near-Earth space environment. Although the GOES classification is commonly used to indicate the size of a flare, it is only one measure.

      Here is another reality regards these CME's and flares. The matter in them leaves the sun and accelerates rapidly upon exiting the sun. This isn't like the acceleration of a gun. In a gun once the bullet leaves the gun, it begins slowing down. In a CME the matter gets faster and faster on the way out like it was riding a railgun track all the way out. The matter in these X-Class flares left the sun and in about 16 hours are reaching the earth. They left the sun at a velocity that was a few thousand m

      Bad math at work. By the scale listed, an M9 would be four times more powerful than an M5, so there is no way an X2 is four times more powerful than an M5. An X2 should be 7 times more powerful than an M5. (M6-M7-M8-M9-X-X1-X2)

        Actually, shooting a high-powered rifle, while looking down at close range, into standing water is ... a really bad idea. Presuming that you really ARE talking about an "elephant gun [wikipedia.org]," the amount of energy being released is really quite astounding. Depending on the round you're using, you could be delivering over 8,900 foot pounds of muzzle energy [wikipedia.org]. With that projectile doing 2,000 feet per second into a barrel of water right in front of you, some interesting things are going to happen.

      Because, um, we can't? I doubt organic computing has advanced far enough. Last I heard, a mouse brain could auto-pilot a plane, but I don't think that is what scientists are really worried about. A few brief glitches doesn't justify making the enormous investment to create not only wholly organic computers, but completely organic sensors (like gyroscopes. How are we going to make an organic version of that?) We don't have the knowledge or the means to do it. Besides, I have a feeling that an organic satellite would have more problems in space than a mechanical one. A mechanical one would have to worry about a few solar storms and collisions, both of which are only intermittent concerns. Organic satellites would have to worry about a lot of things, like solar wind which would be constantly ablating the surface (think sunburn). An organic satellite would need to feed itself. The only organic means of converting sunlight into energy that I can think of requires a steady supply of water and carbon dioxide. Out of curiosity, how would we communicate with it? Moving on, I guess you could say that an organic satellite could heal itself. A big plus, until you realize that means that it can also develop cancer. I know, it sounds retarded, but there's a lot of radiation in space. Even with shielding, that's a lot of exposure. Instead of having to go on missions to replace a faulty sensor or transmitter, we'll need to send missions to perform surgeries in zero gravity. Sounds fun.

          Wrong. As someone else pointed out, the inner ear depends on gravity a great deal. Why do they call the zero-grav training plane the "vomit rocket?" There's also a flight training exercise where an instructor and a student go together into a plane with an obscured canopy so they can't see outside. The instructor flips the plane upside down at a speed so that the centripetal force of the plane remains at 1 G. When they change the controls to the student, a lot of them end up never realizing they are upside down until the instructor tells them. The point is to trust your instruments. If you're flying in bad weather, you can't trust your inner ear, but you can trust the gyroscope.
