In the future will it be possible to eliminate the big backpacks on space suits? I think so, and here are some things that I envision for the space suits of the future. Enjoy!

Comments were turned off for: This is my friend 1968. So I will post my thank you here. I loved the film Fran. Many thanks.
Have you solved global warming…..
I have a friend here in Brazil that looks like you, even have similar way to talk and the laugh. She is also so smart, like you.. You both are the fractal pattern that repeats in different places. This amazes me so much.
It will come in pill form. Just add water.
just send the teslabot out on his lunar segway with moon FSD to do the hard stuff with occasional telepresence intervention, while you relax in you cosy little moon spa watching all the action via your lunar certified apple vision pro.
There’s also the matter of water vapor that would have to be removed so it doesn’t fog the window or interfere with any electronics. It would require some kind of desiccant system.
Scuba drivers have chemical rebreathers that are highly efficient and doesn't need electricity. Also pure Oxigen atmosphere is not flammable, as a start, you need some combustible, and that's easy to avoid inside a suit. Then also, you can go with low pressure oxygen, reducing the risk even more.
Apollo used 100% oxigen atmosphere for the suits and the capsules at lower than atmosferic pressures (4psi) with no problem.
Apolo 1 fire was caused by Oxygen at high pressure (They needed to maintain the positive pressure of the spacecraft even at sea level for the seals to work properly). At high pressures, normally non-flamable objects can burn easily, but the main culprit was some nylon wrapping (seems non-officially there).
On later flights, they added 40% nitrogen for the launch, which was slowly vented out with time until reach the 100% Oxigen level.
We also exhale a substantial portion of the total oxygen in the form of H2O, not only CO2. You can also extract O2 from the water by electrolysis. The balance is such that it would be approximately enough to use only the oxygen in exhaled CO2. If you use all the O in both exhaled CO2 and H2O, you end up with more O2 than you inhaled. The excess O comes from the carbohydrates you eat and drink.
Why the question mark in the title?
I wonder if this could be used with diving as well. There the O2 level would have to remain low on dives below 10 meters. Pure O2 becomes toxic at 10 meters and air becomes toxic at about 90. Using N2 as an inert gas on dives below 20 meters can cause problems with bends and N narcosis. If helium is used, it dissipates more quickly and doesn't have the narcotic effect of the N2. This is why it is used for deep dives. The only side effect is talking like Donald Duck. If the CO2 was scrubbed, leaving the O2 & He mixed gas, the only reason for addition of more O2 & He would be an increase in pressure because of depth. Then there's the problem of venting as you 're coming up to resurface. Maybe you could do a video about that, or better yet a mechanical gill that could extract O2 from the water. That would be awesome!
I want to see you make a video in space Fran. No joke! @EverydayAstronaut
That only can happen if we manage not to destroy ourselves
things get smaller as tech advances.
Great concept. What would provide the electricity and how much would be needed?
Hat is a very good idea. If you want to work on an Earth bound practical prototype, look into diving gear, specificaly the Re-breather ' systems. They incorporate a small MPU with sensors to controll the O2 and CO2 that divers have in a recirculating system. I would love to see such a system become Open Source to prevent Space Exploration being limited to big companies and countries.
You mean a rebreather? Something similar is already used in diving.
