How Living on Mars Would Make Life Better on Earth

Thanks to LEGO City Space for helping us envision life on Mars! Go to lego.build/CITYSpace to start your next space adventure.
If we ever want to live, sleep, eat, and breathe on Mars, we are going to need some the best tech humans can dream up - and as a bonus that tech might actually help tackle challenges right here on Earth!

@Diesel Techie It's worth it if you ask me. It lasts for a lifetime, and you can build pretty much anything with it. I learned *so much* about mechanics from playing with that stuff, and it even helped me figure out how pneumatics work. The freedom of putting stuff anywhere you want makes it easy to try things out, and that helps you understand what you are dealing with. Lego is definitely the toy I played with the most when I was a kid - and I'm still inclined to pull it out from time to time. I can't say that about any of my other toys.

The low pressure and over abundance of Co2 would be instantly lethal to all known plants, and contrary to popular belief plants do need some O2 to function, a better start might be something like cyanobacteria that produce O2 purely as a byproduct, still need to deal with the pressure among other issues but it's a start

If the smashing of CO2 into Gold Foil bends the molecular structure, they could likely be making said CO2 molecules polar in nature, like H2O. If that's the case, then it might be possible to use high electromagnetism or heat (or both) to further the bend magnetically and have a better yield on the O2 production.

I thought we were gonna use the Sabatier reaction. CO2 + 4H2 = CH4 + 2H2O. Then you separate H2O back into H2 and O2 with the method of your choice, then you can separate CH4 into C and H2 using methane cracking. I don't know the efficiency of methane cracking, but both the Sabatier reaction and electrolysis of water has a theoretical efficiency in the 80%. This way you don't get any CO2 left, it's converted into Carbon, which could be used for making DIAMOND PICKAXES!

There's also not much of any atmosphere and no magnetic field hence radiation is a very serious problem and then there's the one third gravity.

ALL PRAISE LEGO SPACE! I remain skeptical about long-term Martian surface habitation, much less colonization, until we have a better handle on the lifetime effects of sub-Earth gravity on health. It strikes me that all the problems of living on Mars (entirely worth solving, I must stress), are equally applicable for orbital habitats able to use rotational 'gravity' and thus provide a 'basecamp' facility for Martian surface operations where Mars-nauts can tele-operate rovers and coordinate surface operations from, provide a waystation for traffic between Mars surface and Earth rendezvous flights, and provide medical facilities to help long-duration surface personnel re-acclimatize to Earth gravity. It would also be a great place to retreat to in case a surface station needs to evacuate for whatever reason. I just don't think Mars operations will be much more than Apollo-scale surface jaunts until we have this kind of support capability.

Oh, and it gets worse. Without atmospheric oxygen, metal does not form a protective layer of oxidation as it would here on Earth.

[@BigSwede7403]

Oh we are recycling a _lot_ of steel. The mill in my town Goes for 90-100% scrap steel in every melt, just adding "fresh" steel when there is not enough scrap, or the scrap they have is aloyed in the wrong way to be good for the particular batch. (Not counting stuff like nickle and stuff which is added as needed to make the right type of steel for the batch.) Concrete, not as good, but we (humanity in general) are getting better at it because generaly speaking the recycled stuff is starting to be cheaper than the freshly made stuff. Mainly because they want to separate the metals to sell anyway, so you get recyclable concrete as a byproduct. Bricks are a bit harder because they either break or stick together, meaning it takes a lot of work to recycle them, but it´s starting to move along slowly too. Or so i´ve been told.

@@BigSwede7403 you're correct but most is not construction based (rebar from concrete reinforcements) or across the country. It's also no where near the amount we create.

[@KnightsWithoutATable]

The Sabatier reaction lets you take CO2 and hydrogen and then convert them into water and methane and heat. The reaction needs pressure, a nickle catalyst, and 300 C to 400 C to get it started, but it would quickly become self sustaining and even create excess heat that could be used to generate electricity or power other reactions. You can use this electricity to split the water into oxygen for breathing or rocket fuel when burned with the methane and recover the hydrogen to continue to use in the Sabatier reaction. This also give you water for drinking and growing plants. You can react steam with methane and heat from the Sabatier reaction to create ethylene, which is used in crop cultivation and ripening while also being the key compound in making multiple thermoplastics, such as polyethylene, which is good at stopping ionizing radiation. There is currently a massive amount of research into making ethylene using oxygen and methane only, but it is currently not a commercially viable process. I think there was a video on this chain of chemistry that would only require us to send a small power/heat supply, hydrogen, a few chemical reactors, and some robots to Mars to set up a base for human habitation construction. Considering the reduced mass that there would be and that you could produce the most of the mass of fuel for the return journey on site makes it very attractive. The 3d printing contest winner could replace the PLA in their mix with polyethylene since both are thermoplastics. The real challenge would be to get the automation to work reliably enough without human intervention at least to a point to create the first base that could then self expand with each subsequent shipment of hydrogen.

[@youknowit789]

@Mario Perez You could even then use the methane to generate power for electrolysis and split the hydrogen and oxygen back up from the water and restart the cycle. There is some energy loss each cycle but with solar panels you can basically swap between natural gas, water, and oxygen as needed :)

Wait the minute, what about producing nitrogen on Mars? I doubt you can just breathe pure oxygen on Mars like the astronauts on International Space Station.

[@lobsterbark]

They don't use pure oxygen in space, it's way too dangerous. Even stuff like polyester clothes and stuff burn extremely easily in pure oxygen. Plus, things degrade from oxidation a lot faster. A high co2 concentration is still bad for humans even if there is plenty of oxygen present, for instance an atmosphere of 25% co2 and 25% oxygen and the rest nitrogen would kill a person pretty quickly. Even a co2 level as low as 0.5% is not something you can live in for more than a few hours to a day, regardless of oxygen percentage. Terraforming Mars to the point of being able to live on the surface with nothing more than an airsupply and some warm clothes is probably the most humanity can realistically ever hope for, and even then that is a huge stretch.
