It's an important consideration, isn't it? Moon dust will stop emitting secondary neutrons and gammas as soon as you take it out from under the sky...

Yes, we've all seen this. Several times already. It's entirely non-contributory to your claims, however. Grant Hutchison

Doesn't ring a bell, sorry. Of the several reasons you don't use a Hohmann to get to the moon, one is because of ... well, the moon. Hohmanns are...

FYI: None of the Apollo orbits were Hohmann orbits. Grant Hutchison

What he said.^ I'd also point out that Lord Foul hasn't even compared like with like to the minimal extent of matching proton energies. There's no...

You're funny.:lol: Since I haven't noticed an answer to any of them so far, I'm interpreting that statement as a roundabout way of saying, "I have...

Utterly. Beyond. Belief. That "really good" article is the basis for the set of calculations that you recently dismissed as:Do you ever read any...

See my diagrams. That's exactly how it worked. Grant Hutchison

You don't launch a rocket to the west on a planet rotating to the east, unless you want to use an unfeasible quantity of fuel. Any launch azimuth...

Actually, the location of Kennedy is really important, because it sets limits on the inclination of the orbit to the geomagnetic equator. Which was...

Here's a diagram of the situation. Vantage point over the Pacific, with Cape Kennedy on the eastern limb: Here's a view of the ecliptic, lunar...

Glad it's of interest. :) Grant Hutchison

Well, I noticed. Thanks. :) It's very interesting, and I'm trying to get my head around it. It raises the issue that the specific manner in which...

Wrong on two counts. And yet entirely consistent with the Apollo trajectory and the distribution of radiation in the VAB. Do you have anything...

If it helps, I have some diagrams in my little article How Apollo Got To The Moon which illustrate the key concepts here. Grant Hutchison

I'm thinking (because it is true) that the moon blocks GCR. And within that part of the sky occupied by the moon, the GCR is replaced by radiation...

I say you have provided no measurement of the dose rate in cislunar space contemporaneous with the Chang'E-4 surface reading, and the LRO reading...

There does indeed seem to be a bit of confusion. Read the words in LEARN MORE, which I quoted earlier. They're really clear. Grant Hutchison

Nope, it doesn't matter how often you post the link, they still haven't magically turned into cis-lunar doses. We've been through this multiple times...

Yes, your attachment was raising the error message I showed you. Still is. Anyway, that's just another post of the same LRO surface data you invoked...

Grant Hutchison

Here's mine: Where is the contemporaneous dose measurement in cis-lunar space that convinces you the Chang'E-4 surface dose rate is higher than...

Oh for pity's sake. Please click on LEARN MORE. And then come back and start answering some of the outstanding questions. Grant Hutchison

No. Posting CRaTER data (even if it were appropriate CRaTER data) won't help you, because (as previously revealed) these dose rates are "corrected...

If you want to use that figure, then slightly lower than "expected". The Apollo radiation techs predicted an average 1.2 mrad/hr for the lunar...

Both Apollo 11 and Orion EFT1 launched from Canaveral/Kennedy early in the launch window, so very similar inclinations in the region of 30 degrees....

To be fair, I don't think I've posted an Orion orbit on this thread. You're maybe thinking of this old thread I started a few years ago:...

Oh, I see. You're using a Quality Factor of 1 to convert Sievert (equivalent dose) to Gray (dose). That makes nonsense of your calculation,...
