Re: Testing My Hacienda On Mars Society Devon Island

Energy from the sun

Devon Island is the largest uninhabited island on Earth. It is found at 75oN and has  surface characteristics that strongly resemble the surface of Mars. Being so far north, Devon Island has solar irradiance similar to the solar irradiation on the Martian Equator. Except for a brief period in June, the intensity of the Sun on Devon Island never exceeds the solar intensity on Mars.

Although the light intensity (near local noon only) on Devon Island is similar to that expected on the Martian Equator, the duration of daylight during this time is 24 hours per day because of its high latitude (above the Arctic Circle).

On Mars, near the equator, the duration of daylight is about 12 hours, followed by approximately 12 hours of darkness.

Mars, spring is 7 months, summer is 6 months, fall is 5.3 months and winter is a little over 4 months long..

The oscurity opaceness of the light and difussing of its energy can not be predicted for intensity level or for its duration hence why we need more than solar for mars.

For SpaceNut re #101

Thanks for this overview of Devon Island, and for the link to the slideshare site, which I had not seen before.  It appears to have potential for further visits. 

The computation of light levels would appear (to me at least) to have direct application for lighting of interior spaces.

I'm still hoping someone will discover any available reports from the Russians on their development of subterranean living/working spaces in their far North.

We need to keep in mind that we will make methane by other means such as an  Anaerobic Digester to Convert Organic Wastes into Biogas: System Setup and Basic Operation this would also include feeding algea that is not used into the source of materials to feed the digester....

https://sswm.info/sswm-solutions-bop-ma … l-scale%29

The calorific value of biogas is about 6 kWh/m3, what corresponds to about half a litre of diesel oil.

The atmosphere of Mars is the layer of gases surrounding Mars. The atmospheric pressure on the Martian surface averages 600 pascals (0.087 psi), about 0.6% of Earth's mean sea level pressure of 101.3 kilopascals (14.69 psi)...

While the oceans have more co2 desolved it still makes sense to test out production safety for anything we would want to send to mars.

Re: Testing My Hacienda On Mars Society Devon Island

The average insolation in the SE England is 1000kWh per square metre per year.  That works out to an average of 114W/m2.  About 50% of the Martian surface receives more insolation than that.  In Scotland, insolation is between 700-800kWh/m2 per year.  The UK has one the highest agricultural productivity in the world.

I don't think Martian insolation levels pose a severe limitation to crop growth.  A bigger challenge is keeping agricultural areas warm.  There is enough light to sustain most crops.  But not enough heat.  Frost kills most plants.

HMP Field Report: MIT – Modeling and Researching the Logistics of the Haughton-Mars Project Research Station
https://spaceref.com/status-report/hmp- … h-station/
As part of the NASA funded Human and Robotics Technology (HRT) project on “Interplanetary Supply Chain Management & Logistics Architectures” we are researching the applicability of terrestrial supply chains to planetary exploration. One of these tasks (WBS 2.3) includes modeling and researching the logistics of the Haughton-Mars Project Research Station (HMPRS). The overall goal is to obtain lessons learned for Supply Chain Management (SCM) to remote environments and to test new technologies and procedures that will
enhance the ability of humans and robots to jointly explore remote
environments on the Earth, the Moon and Mars.

Re: Testing My Hacienda On Mars Society Devon Island

There really has been lots of good stuff coming out from these sites but the supply chain and packing is the one you cannot fail at.

Now how am I going to pack this into a space that is smaller than the largest item?

It is surprising to see how much stuff you need to a earth location, just think if you need to pack for redundancy for mars

Re: Testing My Hacienda On Mars Society Devon Island

It seems isolation and depression has an impact on teen life with news of a Coroner’s inqueston the death of First Nations teenager who went missing from group home.

We do have threads which talk about psycological issues and mental health in a far away colony.

Devon Island and Mars Analogues.
A feat still making news

Here is an experience shared by a space historian on “A Month on Mars”

https://web.archive.org/web/20221004151 … h-on-mars/

The Haughton-Mars Project on Devon Island served as a reminder of both one conceivable future and our frenzied and violently altering past. It is a vast, desolate, and ominous terrain, covered in grit and dust, with boulders and other structures that are uniformly sharp enough to sever skin. However, the far views show gentle undulating plains with sporadic buttes, gullies, and low hills. The valleys wind interminably from one place to another, with a few trapped lakes of brilliant meltwater scattered everywhere.

15% of Canada's electricity comes from nuclear power, with 19 reactors mostly in Ontario providing 13.5 GWe of power capacity.

All currently operating Canadian nuclear reactors are a type of pressurized heavy-water reactor (PHWR) of domestic design, the CANDU reactor and CANDU reactors have been exported to other nations or kingdom and states.
