That's why I keep my toothbrush wrapped in paper.

It's this meme all over again but this time it's Israel vs. Russia.

 

... and neither does the author (or so I believe - I made them both up).

On the other hand, AI is definitely good at creative writing.

Wherever it comes from, sex must be pretty old. Am I correct in the assumption that all Eucaryotes do have the ability to have sex? (ofc with minor exceptions)

I specifically miss my philosophical and spiritual communities from Reddit. I love learning about mythos and different religions, especially the more esoteric stuff, as well as political philosophy. That content just isn’t here in the same way (or sometimes, at all). It would be amazing to have that here.

If you speak german, that is what the community [email protected] is all about.

No, I think it makes sense.

Living organisms use ions internally (positive charges) because they produce something (like fruits).

Technology uses negative charges because it harvests those fruits, and takes them away (negative).

Yeah, I predict that in the future, you can't expect that content on the internet is written by humans. If you go to the internet, then it will probably not be to connect to other humans. Maybe you want to know something that a bot can tell you or you have some administrative task to fulfill, like filing a form.

So, the major issue with settling moon is resource availability: water (!), carbon, fertile soil, and energy.

On the moon you have none of that. Maybe, with a lot of luck, you find water somewhere. Then you need carbon, energy during the long moon nights, and soil that isn't razor sharp particles.

On Mars, you have all of them: low concentrations of water in the atmosphere, carbon from carbon dioxide in the atmosphere, soil that isn't razor sharp (thanks to erosion), and the nights are short enough that you can make it through them.

All life is based on large quantities of Water. The same will be true on Mars. There has to be a major and reliable source of water on Mars.

What options are there? I read an interesting article yesterday that said "Our results show a two-order-of-magnitude diurnal variation of water vapor pressure, suggesting a strong atmosphere-regolith interchange", in other words, the soil on Mars extracts water out of the atmosphere in the nighttime and releases it in the daytime. This means that if we collect the soil and "bake" it, it would release water vapor in a controlled environment. We could then condense that water vapor to get useful/useable water.

 

Hear me out. This thought process requires a bit of knowledge of physics/chemistry.

On the martian poles, there are vast quantities of frozes CO2. This frozen CO2 exerts a certain "vapor pressure" - in other words, a certain partial pressure of gaseous CO2.

Now, if we convert this CO2 into O2 by removing the carbon out of it, the concentration of O2 in the atmosphere increases. And therefore, the concentration (and partial pressure) of CO2 decreases.

But since the frozen CO2 on the poles causes a certain partial pressure of CO2, a bit of the frozen CO2 will go into gaseous phase to refill the CO2 partial pressure.

So, by converting CO2 into O2, the concentration of O2 increases, but the concentration of CO2 stays approximately the same. As such, the total pressure (and density) of the atmosphere increases. This would happen if large-scale biological photosynthesis/growth took place.

 

Does anybody have good data on what radiation exists in space?

I have found sporadic information, such as on Wikipedia but I wonder whether there's nicer, clear structured information on this topic?

Hi there, I'd like to connect with people to discuss technical aspects of settlement of mars.

I'd look at a house on earth and ask: what things have to be supplied from the outside; what things can be produced inside the house? Houses on earth have piping for water, and cabling for electricity.

Plants can be grown in a green-house using these two ingredients, and the people can sleep in a spaceship.

Comment whatever comes to your mind.

 

Tell your republican friends/colleagues/whatever that solar panels are a good thing because they let Jesus into our lives.

Hopefully that will accelerate the green energy revolution.
