I just got back from a trip to DC to visit my Son. We went to the National Air and Space Museum. They had 2/3 of the building closed for “updates” or something. what a huge disappointment! There was no notice I saw anywhere until we got inside.
Hol up we can’t say “poop”?! It isn’t gross - everyone does it! I poop every day, sometimes twice, and I love it. Sometimes it’s the best part of my day. I stand up with a contented sigh and look down at my fresh lumpy loaf and, with a smile, I say “I made that.” I say we be proud about our poop and proudly descriptive! Love the vid :)
I think that it was the movie 'Space Cowboys' where Courtney Vance shows the 'recruits' (the old guys) the 'ACM' (A$$hole Centering Module) Anyone know if I got this right? What a brilliant vid! Number 1 and number 2...FML I'm dying...
A more efficient use on Mars is as fertilizer. They will have to grow their own food and it takes biomass added to dirt to make crop friendly soil. The more they make the larger the crops they can farm. It will take years to gather enough farming soil to feed just one family (2-1/2 acres per family). So when they hit the surface they better get to work making farmable soil and not waste it.
They'd have to bring the soil with them, huge processors, or possibly bring mining equipment for producing soil. Recent survey missions have shown large amounts of hydrazine in Martian sand. So you wouldn't want to use it for growing crops as that'd be some spicy guacamole for your DNA.
@@JohnSmith-sk7cg certainly Earth's soil was at one time toxic. But that's what the selection of plants, molds, fungus, bacteria, worms, amd insects were for -- natural soil processors. They can do the same on mars. Hydrozene (N2H4) can convert to non toxic elememts by some bacteria. Or burning (Oxydizing it) converts it to N2 + H2O. The picture is not as bleak as has been portrayed.
@@LG-qz8om It's actually way more bleak for unrelated reasons, one of them among many is the lack of a magnetic field preventing any form of sustainable practical atmosphere, but that's besides the point. I know the Martian dust can be stripped of hydrazine, but to do so on the scale of a self-sufficient outpost would require the processing machinery I mentioned.Doubly so if you're trying to use it for human-grade food rather than just extracting what you can from it for rocket fuel. So the question is why would you bring over all this processing equipment and construction when you could just bring the soil directly from Earth for the initial batch and then work the martian dust into it over time on a much smaller and lighter footprint? Mars is great for science and exploration, but it doesn't make much sense in terms of long-term colonization.Its atmosphere is thick enough to need to worry about transit, but too thin to provide any benefits and the planet isn't rich in any resources we particular care about. If one wants to colonize offworld, they're better off building an O'Neil cylinder outside of a gravity well or choosing a place with a thicker atmosphere like the clouds of Venus for better shielding. Or if you want a relay to the solar system, the moon.
why not use the number 2 as fertilizer in an onboard greenhouse? this would allow for and unlimited supply of food and water making long duration mission and colonization easier
I am still surprised there is not an astronaut that is a dedicated janitor/plumber. With other duties like everyone else. To not have one or even a team is reckless if not stupid.
OMG! It gets even more extreme! We are going to be building human habitats on the Moon and Mars out of poop and regolith! 🤣 We may like to think of ourselves as extremely advanced, but holy cow! We are a primitive civilization! 😅
You need to look at the carnivore diet and how minny times a human needs to use the bathroom on this diet and see if it would work for long space trips
