Two points, the time required to get to the moon from the Earth was far more than the 12 hours you're claiming (237,000/20,000=@12 hrs), meaning the velocity was much lower than 20,000mph.
Quoting: Anonymous Coward 67748437 It's a transfer orbit, not a trip down the highway. You can't do simple division to figure out velocity specific to any of the bodies in question.
Quoting: Anonymous Coward 2380183 No, you can't, that's MY point. You said they went through the van allen radiation belts at 20,000mph and I happen to know their actual path would have had to have been spiral,in fact simply modifying an Earth orbit until it intersected with the moons orbit, meaning the time they spent in the affected zones was much longer than your 20,000mph figure is intended to indicate. Their actual velocity would have had to have been much slower, at that velocity they would have one tiny window of error and it woudl have required a tremendous deceleration to effect capture by the moons gravity.. To calculate the actual time spent in any zone you cannot cherry pick data and say they moved vertically through the zones at 20,000mph, the actual vertical velocity would have been much much lower. You also cannot use average flux values to prove anything. Particle density in the lower proton belt varies radically from minute to minute.
Also, it is impossible for Apollo to have penetrated the VAB at any latitude other than the one it was launched at because it had to intersect the moon's orbit in essentially the same plane it orbits Earth to have the equatorial orbit of the moon it did and land at the Sea of tranquility.
Quoting: Anonymous Coward 67748437 More complex than that. The Moon's orbit is neither aligned with Earth's equator, nor the ecliptic. Nor is the Cape on the equator; launches from there are not equatorial either (much less aligned with the solar ecliptic).
Quoting: Anonymous Coward 2380183 Let's be specific. the moons orbit in inclined at 5 degrees to the ecliptic. The Earths rotational axis is 22 degrees inclined to the Ecliptic The moons orbit varies from 0 degrees off of the equator of the earth to maximum of @27 degrees. Apollo was launched from cape Canaveral with a latitude of when the moon was in the moist advantageous position, and Apollo would have had to penetrate the VAB at no more than 27 degrees N latitude at it's lowest latitude, and no more than 33 or 24 at it's highest latitude. The latitude would be changing during the translunar injection SPIRAL trajectory. The illustrations by NASA which show the TLI are false.
.
The best case scenario is 38 degrees latitude, in the thick of the VAB which BTW are extremely variable and vary from minute to minute. Radiation densities are given as averages.
Quoting: Anonymous Coward 67748437 Yes; as weighted averages. Which means the excursions are known numerically and statistically. When you say freeway speeds average 70 MPH, that doesn't imply cars frequently travel at 200 MPH. And it certainly does not allow that every now and then, a car passes at relativistic velocity.
Quoting: Anonymous Coward 2380183 Quack quack, sounds smart , breaks down to total nothing. You said nothign intelligent whatsover here that means anything.
Plastic and insulation can stop SOME particle radiation. They have little effect on electromagnetic radiation or high energy particles.
Quoting: Anonymous Coward 67748437 Everything has a half-thickness. Even dead skin, or nomex coveralls. This is why qualitative statements are misleading.
Quoting: Anonymous Coward 2380183 Nonsense. The particles in the lower proton belt woudl go through Apollo like water though a sieve and the electrons in the outer belt would result in deadly levels of X radiation, which is not attenuate by any of the materials in the Apollo shielding.The spacecraft woudl have been worst than a microwave oven.
This is the real barrier to interplanetary space travel, why it cannot be done until the probelm is solved
The aluminum hull woudl make the problem worst,because particle radiation produces deadly x radiation when it impact aluminum. It also produces secondary particle radiation from the nuclei of aluminum atoms.
Quoting: Anonymous Coward 67748437 Which is desired behavior. The secondary emissions are of lower energies and are largely stopped in the remainder of the material (or the following layers). For an education in how this works, look at the Therac-25 incidents. And remember these were therapeutic machines specifically designed to utilize bremmstrahlung to maximum effectiveness. Yet, the patients who died, died from the original electron beam, NOT from the generated x-rays.
Quoting: Anonymous Coward 2380183 Nonsense. X radiation at the levels that would be produced are deadly for short periods of time. In medical x rays the exposure is not dangerous only because the total exposure time is a fraction of a second. We're talking at least several hours, at a much higher flux.
While in the VAB the Apollo spacecraft would be bathed in electromagnetic radiation many times more powerful than an x ray machine or microwave oven is, which penetrates a body easily. It also important to understand x ray exposure in medicine is limited to a fraction of second because x radiation is in fact extremely harmful to living things. This is why I am reluctant to be x rayed, because I believe a person could easily be killed by a malfunction..
Quoting: Anonymous Coward 67748437 See Therac-25, above.
Numbers, that's what's important. You wave your hands and simply claim that because so and so source exist, the Apollo capsule "Must" have been exposed to a searing hell.
Quoting: Anonymous Coward 2380183 It is not me doing the handwaving and it is not me having your material censored.
I am within miles of research reactors, tens of miles of power reactors. The local rock formations include natural uranium, and the so-called "radon daughters" (a collection of active radionuclides from the various decay chains) are known to collect in basements. There is detectable nuclear fallout in the soil, in fact, in the metals I work and in my very bones. There are cosmic ray showers. I have worked around multiple sources of hard x-rays with not always adequate shielding, and recently, too. The very sun is a source of x-rays. I can generate x-rays -- x-rays with sufficient penetrating power to expose photographic film! -- simply by unrolling a strip of tape.
Quoting: Anonymous Coward 2380183 Which proves the Apollo film record is fabricated. Thank you.
