I posted a comment on Aulis, and an editorial was attached. I was wondering whether anyone was interested in commenting.
I said: "If operating in the van Allen Belts is a problem, then how do commercial satellites (such as communications satellites) operate there now? After all, the geosynchronous orbit where they operate is inside the belts. I understand their electronics are hardened to an extent determined by reference to NASA data. If NASA was understating the amount of radiation present in the belts, then those satellites would be failing frequently, and NASA would quickly come under investigation for supplying dud information. "Peter B Canberra, Australia On Tue 16 Jul" And Aulis replied: "For an analysis of the degree of authenticity in the official NASA line concerning the radiation hazards to both technology and bio-organisms prior to and during Apollo, please refer to the subject of radiation in DARK MOON. Also see the Aulis News Item 'Solar Flare Halts NASA Launch', as well as the recent announcement concerning radiation by NASA Administrator Sean O’Keefe. These items can be found on aulis.com. "In particular, we recommend you read Radiation Belts Threaten Satellites, Astronauts on http://www.cnn.com/TECH/space/9812/08/radiation.belts/ "The Apollo flights were supposedly ‘designed’ according to the scientific knowledge at the end of the 1950s – when the official line of thought was that the van Allen Belts followed a steady, consistent and (therefore open to prediction) pattern of activity. However, research published in 1998 concluded that these already intense belts of radiation can become excessively powerful in mere seconds, and such effects extend down into the atmosphere. It is therefore obvious that if insufficiently protected, satellites are affected as well as anything or anyone that is in space and unprotected. Moreover, according to this 1998 information adequate protection costs too much and makes craft too heavy to launch. This, of course, was even more true of a lunar launch during Apollo. The Apollo astronauts were not protected against such extreme conditions, and mere seconds between states cannot be predicted. So for NASA to state that it ‘planned for any SPE’ is somewhat short of the mark – indeed this ‘new’ information shortens the odds on the Apollo astronauts and their craft avoiding a problem in the van Allen Belts drastically. However, the discrepancies concerning Apollo emerging today would tend to indicate that this ‘new’ radiation information might well have been known, or at least suspected in some quarters, long before 1998. "Aulis" Anyone? |

Well, you'll probably get a lot of replies from people much more knowledgable than myself, but I can't resist observing how much space they used in not answering your question.
""For an analysis of the degree of authenticity in the official NASA line concerning the radiation hazards to both technology and bio-organisms prior to and during Apollo, please refer to the subject of radiation in DARK MOON." Thank you for the reference to such an authoritative source. What about the comm satellites? "However, research published in 1998 concluded that these already intense belts of radiation can become excessively powerful in mere seconds, and such effects extend down into the atmosphere. It is therefore obvious that if insufficiently protected, satellites are affected as well as anything or anyone that is in space and unprotected." "If insufficiently protected" is a great outski. The conclusion they apparently want us to draw is that before 1998 we didn't know enough to design spacecraft that were sufficiently protected. What about the comm satellites? How often did the pre-1998 models get zapped, how long was their mean lifetime, and what does this tell us about the likelihood of a really hazardous event happening during a particular time interval, say, the duration of an Apollo mission? "Moreover, according to this 1998 information adequate protection costs too much and makes craft too heavy to launch." And what about the comm satellites? Oh. I get it. If adequately protected spacecraft are too expensive and too heavy to launch, then there must not be any. Therefore, either I've never had a phone conversation with anyone in Europe or my calls were routed through a trans-Atlantic cable, complete with delay lines to simulate 45,000 miles worth of propagation delay and deliberately introduced crosstalk between transmit and receive to simulate echo suppression artifacts. I'm impressed. Two paragraphs worth of text and never do they directly address your question. If their contention that all the information on radiation hazards available to the designers of Apollo was dangerously wrong is true, then what about nearly 40 years of succesfully operating comm satellites within the Van Allen belts? About the specifics of the radiation environment in space I admit I don't know bubkes. Recognizing evasion and handwaving doesn't require an advanced education, and that their reply is made of just that is as obvious as what a brick wall is made of. On that basis, I say it's spinach and I say the Hell with it. |

I love this. They obviously didn't read the website very well.
The website clearly states this new "killer electron idea" is only a theory. And it takes an accumulation of these electrons to disable a satellite. It also states that the implications to NASA is less clear. Again it looks like buy our book. |
