Re: RobertDyck Postings
For RobertDyck re post about civilizations in Google meeting:
https://newmars.com/forums/viewtopic.ph … 95#p236395
Thank you for this interesting reminder of the deep history of human evolution over recent millennia!
Thank you for reminders of the hints of history that are preserved in the old testament and to a lesser extent in the new one.
This post is offered to (at least try) to remind you that you offered to show us a list of 9 indicators for the collapse of civilization.
GW Johnson has published a similar list for the United States, but (to my knowledge) that list is distributed to only a few folks.
Please show us where we can find the list you have studied, and from which you remembered several elements.
I have no doubt the United States is at risk of collapse. My only observation is that the United States has ** always ** been on the verge of collapse, although there have been (brief) periods when the conglomeration of people alive at the time managed to get their act together. We are clearly NOT in such a time.
****
As a side note .... I appreciated you and kbd512 reviewing the deterioration of nuclear warheads and delivery systems for them. You will (surely) NOT have failed to notice that the US administration thought it was a good idea to fire the folks who care for our nuclear arsenal .... Whether any of the personnel affected by that order are still on duty is anyone's guess.
An obvious sign of the imminent collapse of a culture is failure to maintain it's weapons.

Re: RobertDyck Postings
For RobertDyck re new topic!
Thanks for adding the new topic in Civilization, and for the opening sequence of posts with links and (really helpful) commentary.
This new topic should be of interest to most NewMars members, because a strong US is needed to support the Mars venture.

Re: RobertDyck Postings
For RobertDyck re fighter topic...
One recurring theme that I picked up from Sunday's discussion was the problem of counter-measures for fighter pilots in the modern theater. The munitions that are most likely to be aimed at a fighter are self-guided systems. There is a small chance that pure dumb mass may be thrown at a modern fighter, but by far the more likely threat is from self-guided systems.
As you and your countrymen try to figure out how to defend a huge territory, I'd like to toss into the mix the idea of laser defense systems. These would need to cover 41252 square degrees, so the systems would add mass, but perhaps that mass would be worth the investment.
If the idea occurred to me, it ** must ** have occurred to people who are paid to think about defense against modern weapons.
It would not surprise me at all to learn that serious research has been done in this area.

Re: RobertDyck Postings
For RobertDyck ... please take your time instead of responding immediately to kbd512's interesting post in the Civilization topic.
I have a book about how we should deal with the situation if civilization does collapse. The possibility that our civilization might collapse has been apparent to thoughtful people for decades.
You are welcome to ask about the book if the subject is of interest.
It is probably available from the public library system in Canada.
Because of your background (which you have described in many posts over nearly 20 years) I think you would handle collapse better than many of us.
Still, it would be stressful even for you, so I hope it doesn't happen.
But it most assuredly ** could ** happen in today's time of immense power and weak brains.

Re: RobertDyck Postings
For RobertDyck about current topics....
Your initiative about money seems to me to have potential long term value, if you can allow yourself to provide leadership that actually helps to find a solution to a very difficult problem. Money is a short cut to bargaining.
Americans pretend we don't like bargaining, and we definitely save a lot of time by simple setting a price and seeing if people will accept it. If people don't like a price they have the choice here of simply going online or to the next store.
Money is just a high speed mechanism for bargaining. The value of money has to hold long enough to carry out the downstream exchange.
Manipulation of money is something else entirely, and it has been going on for all of recorded history and probably before.
A big stash of gold is about as useless an asset on Mars as the human mind can imagine, but perhaps there is something worse.
***
Your discussion of military equipment to protect Canada in the current period seems vitally important, although it is taking place in a backwater of the Internet where no one besides a very few members will ever take note of it.
You might come up with something that your countrymen would appreciate.
However, the larger picture is how the settlers on Mars will protect themselves from aggression by other humans.
The history of the human race is pretty clear. Aggression is a feature of the biology of humans.

Re: RobertDyck Postings
For RobertDyck te NASA orthodixy ...
SpaceNut just posted some NASA text without explaining is is wrong for Mars.
https://newmars.com/forums/viewtopic.ph … 66#p236566
It appears that SpaceNut has totally forgotten all the hard work that was done by NewMars members to arrive at the Mars standard atmosphere for habitats and for suits.
Please consider assembling a document (post) with links to help SpaceNut to remember all that work.
We do not need more NASA misinformation posted to the forum without correction.
I do have a related question.... the humans who step out of their habitats wearing Mars suits will still have nitrogen in the blood from the habitat. What will happen to that nitrogen as the wearer proceeds out into the landscape while wearing and using oxygen tanks at 3 PSI?

Re: RobertDyck Postings
Use the long-known NASA criterion for no pre-breathe time. The partial pressure in the habitat, of the nitrogen, may not exceed the total pressure of the pure oxygen fed to the suit, by more than a factor of 1.2.
If you satisfy that criterion, there is no "pre-breathe" time associated with donning an oxygen suit and going outside immediately, without risking the bends from the nitrogen.
If you do more than about half an atmosphere of 21% O2/ 79% N2 mix in the habitat atmosphere, at more than around 0.5 atm hab atmosphere pressure, this is impossible to do.
But half or a little less than half an atmosphere of oxygen-nitrogen mix in the habitat atmosphere, meets that criterion for donning a pure O2 suit and just going outside with no pre-breathe.

Re: RobertDyck Postings
For RobertDyck re topic on principles ...
Thanks for your strong follow up to SpaceNut's list of worries...
In the age of Newfoundland, and in every age, there have been folks who made lists of dangers that threatened explorers and adventurers. The early worries about sea monsters turned out to be less of a concern than some thought, but there were plenty of other very real dangers, such as the storms you included in your posts.
I was interested in your point about keels, so asked Google to do a quick lookup. The historical record shows that keels were invented in the BC era, and revised over the centuries to the peak of near perfection developed in Europe and Asia. Here is a copy of the summary:
10 Top innovations in the history of sailing - YBW
Keels have been fundamental to ocean travel since antiquity, with evidence suggesting they existed as far back as 1325 BC (Uluburun shipwreck) and were definitely established by 315 BC (Kyrenia ship) for stability, with Phoenicians around 1000 BC recognizing their importance for sailing, though early keels were simpler center planks; the concept evolved from rudimentary structures to the robust keels on Viking longships, enabling true ocean voyages.
Early Development:
Bronze Age (c. 1325 BC): The Uluburun wreck shows a basic keel, though more of a center plank.
Ancient Greece (c. 315 BC): The Kyrenia ship confirms the use of keels for stability in ocean travel.
Phoenicians (c. 1000 BC): Discovered keels provided crucial stability for ocean voyages.
Medieval & Viking Era:
Viking Longships: Featured true, strong keels, crucial for their long-distance seafaring.
Chinese Song Dynasty (960–1279 AD): Developed adjustable centerboard keels and bilge keels for their junks, enhancing maneuverability and warfare capability.
Evolution in Design:
Keels evolved from simple center timbers to complex structures, becoming essential for seaworthiness, especially as ships grew larger and began sailing further offshore, enabling deep-sea exploration and trade.
I hope you will continue developing the Principles topic, and if you are so inspired, please take on all the sea monsters that SpaceNut listed in his short post.

Re: RobertDyck Postings
For RobertDyck re Calliban's Dome ...
I'm assuming that you have read none of the posts about Calliban's Dome, or the search for a suitable Crater.
The purpose of this post is to attempt to bring that effort to your attention, in light of your recent reappearance in the forum, and specifically your discussion of principles for settlement.
By a process of discovery, guided by Louis original vision of Sagan City, and updated by Calliban's vision of a Superbowl sized dome on Mars, we (NewMars) have identified a specific crater where Calliban's dome would fit nicely.
If you are interested and can find the time, please see if your discussion of water matches up at all with the proposed dome location.
There are many (ie, more than 6) posts about the crater and it's precise coordinates, so I am confident you can find the coordinates if you use the search tool.
I'm hoping you will be able (and willing) to give the proposed site your endorsement.

Re: RobertDyck Postings
For RobertDyck re SpaceNut's history research...
https://newmars.com/forums/viewtopic.ph … 83#p236583
The history of Newfoundland is a bit more complex than your readers might have assumed from your previous postings on the subject. It sure sounds as though crews visiting Newfoundland were there to catch cod, and they ate some of the catch, but apparently their sustaining diet was imported. In light of your quite reasonable suggestion that settlers show they can grow their own food before they leave anyone on a "permanent" basis, I'm hoping you might be able to do a bit more research on your theme that the people who stayed at Newfoundland grew their own food. Please find out when crops were first grown at Newfoundland.

It is near Louis' prefered site for Sagan City which is itself near to the Viking 1 landing site.
I'm hoping the site has favorable properties per your writings on the subject of water and other valuable materials.

Re: RobertDyck Postings
For RobertDyck ... thanks for your post on Canada and the challenge of air defense (or any kind of defense)
https://newmars.com/forums/viewtopic.ph … 92#p236892
Reminder ... I reply in these personal topics to allow your name to remain visible in the Active list.
It seems to me that kbd512 has argued persuasively on both sides of the F-35 discussion. As i read his posts (which takes some doing as well know) it seems to me he is sympathetic to the challenge you and your countrymen face, and in a recent post I thought I saw a ** very ** strong argument for lots and lots of microfighters. It seems to me a small reliable fighter that you can afford to fly frequently to keep training levels, combined with very sophisticated bomber seeking missiles with the ability to evade defenses put up by bombers would be a deterrence that you might be able to afford. It seems to me the F-35's are going to be expensive to own and you pilots won't get much air time.
Why don't you (as a citizen) simply take the best advice you can get and write a letter to the Premier. That's all you or any other citizen can do, but it's ** something*. Debating with kbd512 may be fun and it may add some excitement to your day, but it doesn't help Canada make the best possible decision.

Re: RobertDyck Postings
For RobertDyck re Google Meeting .... it is probably just as well you skipped the meeting...
kbd512 painted a scary scenario in which poor Canada is the victim of a land grab that Canada cannot prevent or overcome.
We discussed all the steps you and your countrymen could take to blunt the hypothetical attack, but as things stand there isn't much to be done.
It's a shame we live in a word with predatory humans but that's the world we live in. In fact, it has probably been true for most of human history.
The best defense is said to be a good offense, and Canada has neither.
However, that said .... I have Google Earth installed so you and kbd512 can dive deep into the details of where to put what equipment if we have the opportunity some time in the future.
