So sure, the sublimator and suit get vacuum should be tested unmanned first. Then they should test them with a human subject.
No. The second test unnecessarily risks human life to obtain no more information about the sublimator than the first test would reveal.
Are you saying it's only moral to wear them when you're already traveling 17,000 mph in an orbit about 250 miles high?
No. I'm saying it's immoral to risk human life just to test a piece of equipment that can be adequately and faithfully tested without it. When the astronaut is doing his job in orbit or on the lunar surface, he is exposed to risk. But that risk is a necessary and acceptable one that is agreed to be outweighed by the benefit gained. That is not immoral.
I say any responsible and reasonable astronaut strengthens and demonstrates their confidence by donning the suit with sublimator and using them in a high vacuum chamber on Earth prior to launch.
I say we've demonstrated you don't know anything about testing or training. So your judgment is moot.
Yes, this is an absurd anomaly.
No. It's you scraping the barrel even harder to come up with some sort of thing NASA did "wrong," for ulterior purposes which you've already revealed and which require you to keep scraping no matter what the facts say. But you have no demonstrable skill, experience, knowledge, or expertise in this area, and you can't convince anyone else in the world that your judgment on the point has merit.
Would you don a spacesuit at the ISS to perform an EVA in orbit if you hadn't already donned that suit on Earth for an excursion in a high vacuum chamber on Earth?
Yes.
