| Dec 11, 2023 at 4:35 | comment | added | phil1008 | Well, I think my answer was really to the question "What kinds of activities, experiment and, procedures done on the ISS must be done in a vacuum or within atmospheric isolation chambers that can be vented directly into space?" | |
| Dec 11, 2023 at 2:29 | comment | added | uhoh | @phil1008 Oh I see now. I meant air-tight chamber, not necessarily vacuum chamber (especially since those don't always handle positive pressure (above the environment) well). I've edited the question to make it clearer. I think your answer is fine now with the heading, but maybe reverse the order so "Preventing Experiment to Environment Contamination" comes first, and note that the 2nd heading is for "extra credit" or "symmetry arguments" or some nice expression indicating extra informaiton. | |

| Dec 11, 2023 at 2:23 | comment | added | uhoh | @phil1008 thanks for the first edit and the heads-up. Hmm... I am not sure exactly what I meant in 2018, give me a few hours to try to reconstruct my thinking. I'm pretty sure I meant something rational but during the writing of the sentence a cosmic ray (that's my usual excuse) must have passed through one of my precious few functioning neurons. | |

| Dec 11, 2023 at 2:02 | comment | added | phil1008 | I think that the last sentence in this question should be deleted as the phrase "must be done in vacuum" is contradicted by "Exclude anything that actually requires vacuum". If the intended question boils down to "What experiments on ISS require the ISS equivalent of a fume hood?" then it not as interesting as the question stated in the body "What kinds of activities, experiment and, procedures done on the ISS must be done "in a vacuum" or "within atmospheric isolation chambers that can be vented directly into space"?" I think I'll edit the question - if no one objects... | |
