As the nation of Asgardia develops, how should the internal biosphere of the nation be composed? The environments oxygen supply should be self sustaining through use of various tree species such as Aspen and Oak trees. A single mature tree can absorb carbon dioxide at a rate of 48 lbs./year and release enough oxygen back into the atmosphere to support two human beings which means large quantities of trees would be needed. Other plant species that may produce a suitable atmosphere inside of the station also include; Ferns, particularly the Japanese Royal Fern, not only release oxygen into the air but also absorb formaldehyde. The Boston fern is noted for adding oxygen and humidity to indoor air. Gerbera Daisy will purify and boost the oxygen level of the air while you sleep at night, making this plant a great choice for bedrooms. Other indoor plants considered highly efficient in oxygen production and air purification include Heartleaf Philodendron, Snake Plant, Spider Plant, Chinese Evergreen and Golden Pothos. What are your thoughts on the plant species needed to be involved in creating a self-sustaining atmosphere? (This subject is also involved with Physical sciences. I chose to post it here do to the main biological concept of flora and not the atmosphere itself as the main subject of discussion).

Let me start by saying that I am not an expert at all on botany, nor an expert really in any field. I like the idea of a self sustaining atmosphere though. I would think that the best way to go about using a botanical garden for a self replenishing ...

It's a good point to have similar plants on board with the proper CO2 to O2 conversion rates. A plant with high photosynthetic efficiency is Sugar Cane at about 7%. Instead of using a plant based method, algae has an efficiency rate that can go up to about 30%. An ...

Do algaes require large bodies of water to photosynthesize effectively?
Jun 24, 01 / Jun 13, 17 09:25 UTC
Yes, algae need large amounts of water, yet they need only sunlight (or another form of energy, like sugar), carbon dioxide and a few inorganic nutrients to grow. Another perk to algae would be their quick reproduction rate making oxygen production much higher than using plants as the main source ...

Aye, such as nitrogen and phosphorus. Would separate botanical gardens spaced at intervals around the space station work better then a central unit? And how would the large bodies of water be stored?

Having botanical gardens around the ship seems to be a more efficient way of spreading out oxygen equally and would require less ventilation than if the system was centralized. Although it probably wouldn't hurt to have a centralized backup system. The bodies of water should be stored in protective units ...

That's what I thought, but I wasn't sure if the separate gardens at intervals around the ship would pose a problem or not, but then again I am going off of my own assumption of the ship being a singular large rotating wheel, allowing anywhere from 5-15 separate gardens incase ...

I'm sure having multiple gardens would be the best idea either way, just in case one has technical difficulties. Besides that it would take less time to spread the O2 around.

I am sorry, I am not a biologist/botanist, but does plants "produce" oxygen? Cause there are two cycles of photosynthesis, light and dark ones. And if during the light there is indeed conversation of carbon dioxide into oxygen, the other way around goes for dark phase: oxygen to CO2. Plants ...

How much of the stations area will need to be covered in oxygen producing vegetation to make an economical difference to Oxygen production

I suggest an integration of plants as much as possible or at least to keep up with the amount of citizens.

I remember looking at an idea for large scale removal of carbon dioxide from the atmosphere. The design was to put a high efficiency light bulb into a clear tube surrounded by a tube containing genetically engineered algae. The algae are engineered so that will will only multiply if a ...

I found this to be an interesting link in regards to the first steps of the station, at least until we can get a self sustaining system into place. https://science.nasa.gov/science-news/science-at-nasa/2000/ast13nov_1 It's an older article, but it does highlight some great concepts for the initial habitation of a station. Especially in ...

The creation of water through water electrolysis, is a method that will work for Asgardia before a proper biosphere is implemented. The hydrogen gas also created through this process may also be very useful for fuel in a power generator (along with the solar panels and possible other methods). I'm ...
