And how many "assertions" can we make without making any assertions? Quite a few, it seems.

Is that steam leaving the plate?
If so, I ask again, what happens under the covering of the PLSS?

Hydro-electric hoses? I'm not sure what that even means.
The LM had independent systems. It wasn't "controlling" the CM. The navigation solutions were worked out on the ground. All they had to do was use the LM RCS engines to orient the spacecraft in the right direction and tell the computer to fire the descent engine for specific periods of time.

Yes, that's where the steam escapes.
The sublimator is at the top of the PLSS (green arrow). The steam escapes through the cutout in the frame (red arrow):

Are SIDs not dangerous outside of the Magnetosphere?
And the magnetosphere has nothing to do with SIDs, because they are the result of electromagnetic radiation, which is not deflected by the magnetosphere. Only charged particles are affected by the magnetosphere.

I know how much you hate grey areas, FoosM, but I just don't understand it.
I don't think x-rays would be any more of problem to them than it would be to anyone in space.

So you dont think hard x-rays would be a problem for the astronauts in the LM?

The x-rays, being highly directional, would be easy to mitigate against. They could have the whole of the CM between them and the sun providing protection.
It had been thought that the X-rays were not copious enough to be a major hazard, but a new study suggests X-rays really do pose a threat to astronauts working outside of protective spacecraft or bases. The research was carried out by David Smith at the Lunar and Planetary Laboratory in Tucson, Arizona, US, and John Scalo of the University of Texas in Austin, US.
Using the observed rate of solar X-ray outbursts of different magnitudes, they worked out that a lunar astronaut has a 10% chance of receiving a dangerous dose of X-rays from a solar flare for every 100 hours of activity outside of shelters.
The level of radiation they consider harmful is 0.1 Gray or more, which can cause bleeding ulcers and other internal damage, and would certainly increase an astronaut's risk of cancer. The Sun has even produced flares that could kill an unprotected spacesuited human on the Moon, they say, although these are extremely rare.
There is no perfect insulator. Over time, the capsule would radiate its heat away.

See thats the problem with the ship (CM and LM) getting cold.
Wouldnt the ship have to leak... or sublimate, for it to start to cool?
Similar to the PLSS, or the LM?
Otherwise its like thermos. The heat stays trapped and only increases in temperature.
Yes, x-rays can be a problem. I said they were not any MORE of a problem for the crew of Apollo 13 than any other space flight.

You dont think Xrays are not a problem for space-farers?
And now you are saying it would be easy to mitigate against by moving the CM around to protect them.
Will did they do that?
So you are suggesting that X-rays are dangerous.

Are you implying I'm a liar, FoosM? That I'm dodging the answers? If I were doing that, I'd quit responding, or forge on ahead with my imperfect understanding of the matter. Intellectually dishonest, yes, but I suppose I could get away with it of I give 'em the ol' flim-flam-flummox. It's not like people in this thread have a long attention span.

I know how much you hate grey areas, FoosM, but I just don't understand it.
what part of solar flare and seeing the date alongside it which corresponds to dates that Apollo space craft were in space, is difficult to comprehend?

Let's see, that translates to a 0.1% chance per hour. How many hours were the astronauts on EVA? 22 hours for Apollo 17. An overall 2.2% chance of a dangerous X ray dose.
Why do I have a feeling of deja vu?
Define "quickly."

Ok, but then dont you think the CM and LM got cold rather quickly?
Recall we were told that the LM had to be cooled while on the moon.
We were told that they had to barb q roll the CM so the sun would heat the craft evenly.
But for Apollo 13 both craft got cold?
Radiator heat load and rejection was determined by use of the total flow and radiator inlet and outlet and evaporator outlet temperature measurements. Typical heat load and rejection under favorable conditions during translunar or transearth PTC ranged between 1170 and 1470 watts (4000 and 5000 Btu/hr).
