What's the best tag for the gas mixture that humans and animals breathe inside spacecraft, 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". – Organic Marble Feb 23 '20 at 5:06
• @OrganicMarble that sounds like an excellent tag to me – uhoh Feb 23 '20 at 5:18
• but that would preclude suit gasses @OrganicMarble. Perhaps the existing life-support tag would be sufficient – user20636 Feb 23 '20 at 10:01
• okay cabin-and-suit-gas-mixture ;-) – uhoh Feb 23 '20 at 10:02
• @JCRM good idea, added, thanks! Perhaps that can even be an answer here? – uhoh Feb 23 '20 at 10:03
• I'd probably suggest "air-supply" as a synonym for it. – user20636 Feb 23 '20 at 10:23
• @JCRM it's giving me flashbacks from the 1980's en.wikipedia.org/wiki/… – uhoh Feb 23 '20 at 11:08
• "air-supply" would be more the tanks and plumbing storing the breathing gases and bringing them to the cabin. – Organic Marble Feb 23 '20 at 22:52
• tag:gasses exists – Magic Octopus Urn Jul 4 '20 at 12:17
