# What's the best tag for the gas mixture that humans and animals breathe inside spacecraft or spacesuits, or one that they don't?

What's the best tag for the gas mixture that humans and animals breathe inside spacecraft, or one that they don't?

's definition says it's the stuff around planets.

Questions regarding an envelope of gasses surrounding a celestial body held in place by the body's gravity.

I just added to How much nitrogen did Skylab and the Space Shuttle carry for atmosphere makeup? but I'm not sure if it's the right way to go.

note: Now I'm also wondering about atmospheres in spacecraft that are not crewed and do not contain animals:

• Shuttle nomenclature was "cabin atmosphere". Feb 23, 2020 at 5:06
• @OrganicMarble that sounds like an excellent tag to me

• but that would preclude suit gasses @OrganicMarble. Perhaps the existing life-support tag would be sufficient

• @JCRM good idea, added, thanks! Perhaps that can even be an answer here?

• I'd probably suggest "air-supply" as a synonym for it.

• @JCRM it's giving me flashbacks from the 1980's en.wikipedia.org/wiki/…

• "air-supply" would be more the tanks and plumbing storing the breathing gases and bringing them to the cabin. Feb 23, 2020 at 22:52

"Cabin Atmosphere"

• I like it, yep!

• My second use of the tag asks about the air inside a spacesuit. I've added that to the title of my question here but I think the tag can be stretched to encompass this air as well. I'll add some usage guidance to the tag

has been used for this in the past, but it probably shouldn't be overloaded that way. Whatever we decide the tag should be, those other questions need to be retagged manually.

• We may not be able to incentivize and/or promote with a special tag-hat the work and therefore distribute it amongst several users, but at least it's extent is finite and well-defined.

• I've adjusted the question to include atmospheres not meant for crew or animals as well

• Just fyi I've just added the tag here as mentioned under OM's answer.
