Here it is so lets see the topics for each part of the body that has conditions associated to non earth gravity as that would also include artificial gravity. Human Health in Space Travel new category. which have been within the ISS general topics....plus others with radiation being the number one in just about every place in the forums discussions. such as inter plus planetary transportation, large ships, human ect....

Thanks for giving Oldfart1939 a new arena to work in!
We can do our part by supporting Oldfart1939 as he may venture into this new space.

The Potholes run from 239001 through 240000 completed without incident.
It found three missing posts: 239531, 239609 and 339610.
Not too bad.

Thanks for that helpful summary of the risks of radiation in space.
It seems to me that this debate is likely to continue for ever, because human beings never have enough information, and often information that humans take in is wrong.
It seems clear that a cosmic ray passing through a human body does damage to the cells it encounters on the way. It seems to me that the human body involved did not need that "adjustment", but there are some who argue that a little damage to the human body is a good thing because it gives the protective systems something to do.
I find this argument of dubious value, but I grant that it might have some merit. Our muscles become weak if they are not exercised regularly. Perhaps the mechanisms that compensate for radiation damage need some exercise, but on the whole, I would imagine the human body will last longer and provide better service to it's owner if it were not subject to these insults.
If I were shipping a group of human passengers from Earth to Mars, I would consider it obligatory to provide radiation protection at least equal to that found on Earth at the surface. We experience radiation assault on the surface of the Earth, but it seems to me we have evolved to deal with it, and that includes repair of damaged tissue.
There are others who will accept a higher risk in order to travel at less expense, and in that case, the kinds of waivers already in place for space flight should suffice to protect the shipper.

A representative of the LK Cokoino company (China) has accepted my invitation to join the forum.
I just created the ID, and am surprised to be able to report that the system accepted a three letter name 'Tan" as the ID.
Please notify Mr. Burk immediately that we are undertaking a venture to see if we might facilitate customer support for this company in the context of the Mars Society educational mission.
I have invited two educators into the forum. Their focus will be learning about the Cokoino CKK0017 robot arm.
Please communicate with Mr. Burk at your earliest convenience to be sure he and Dr. Zubrin are comfortable with this initiative.

Nice to see you constantly looking for ways to help our readers to find things.
The forum architecture sure does not make that easy, but collecting items from the hodge podge we have and offering them in a single unified title will surely help.

In conversation with Calliban, I thought to look for a topic we might have on "Emergency Fire Shelter"
Nothing showed up. Do you know of a place where such a topic would fit?
The solution would seem to me to fit well with the ambient conditions at the surface of Venus, with the distinction that the conditions on Venus are stable, whereas the conditions in a wildfire on Earth vary greatly.

The ISS has all type of experiments, clarks calamities talk about such events, Plus there is one other that I did but its been quite some time ago. Fire has more than heat to it as ther air is filled with many toxins from out gassing...
"clark's calamity", when bad luck is all you have
Fire on the ISS, lunar base or Mars habitat or domes
Business Opportunity Fire Shelter
the heat of venus is hidden in the clocks or skunk works topic for how to cool

For SpaceNut re #4284 and comment in topic about making synthetic fuel.
The links you provided look interesting.
If you find links in the Venus topics about how to cool a probe, those links might contain something useful. The only solution I recall was to use traditional HVAC techniques, and those require radiating into the ambient temperatures, and ** that ** would require materials at the limits of human knowledge. It seems to me that kbd512 found some candidate materials that might work. However, as you know from reading of the new topic, that is NOT what is proposed. A different method IS proposed, which differs from traditional HVAC techniques. However, the method would be familiar to every family that packs a dinner for a picnic.
Regarding making synthetic fuel. Your observation about the desire of those who are earning income by pulling oil from the ground seems to me to be reasonable. However, that is only a subset of the entire pool of capitalists on Earth. The capitalists who are NOT chained to fossil fuels are looking for opportunities to earn income from other activities. That is why you see massive investment in nuclear fusion, nuclear fission, gold hydrogen, geothermal energy, and a myriad of other initiatives having nothing to do with traditional fossil fuels.
If you ever get time to read the series I just posted, you could ** learn ** something. Having just completed the series, I can save you some time. The reason we don't see synthetic fuel on the market has nothing to do with the capitalists who are trying to get the last penny out of the ground that they can. Instead, it has to do with the relative difficulty of creating salable products. The folks who pull oil out of the ground have a relatively easy time processing the raw material to make high quality fuels. It's not EASY and never has been, but compared to making fuel of high quality from scratch it definitely ** is ** easy.
On Mars, on the other hand, there is NO competition from the underground reservoirs. Every barrel of fuel will have to be ** made ** using the techniques that Calliban has been talking about (DME and related). And whatever fuel is made on Mars must be matched up with the corresponding measure of oxygen.
My understanding is there is an outfit making high quality jet fuel from scratch in Peru, but I lost track of that reference and would have to look it up. South America does have oil in Venezuela and possibly elsewhere, but NOT in Peru, so for that country pursuing synthetic fuel makes sense.
