NASA has never publicly demonstrated before independent witnesses a spacesuit with ice sublimator cooling system in a high vacuum chamber on Earth duplicating environmental conditions of orbit.
Now it appears they've never tested a spacesuited astronaut while in a vacuum chamber at all except for that last documented test way back in 1966 when the suit failed causing a near fatality.
I'm puzzled more why they won't even show a video of an ice sublimator in a vacuum chamber with the astronaut outside running on the treadmill.
Our space program is currently a mythological faith-based thing. You insist upon it remaining so.
Once again reminding you of what I asked in Reply #535:

I'd be grateful if you could answer the following questions:
1. Is personal validation the only way you verify facts? If not, who do you trust to give you reliable information about subjects you're personally unfamiliar with and how do you verify their reliability? What's to stop you from using this process with people testing PLSSs?
2. If NASA faked Apollo because the spacesuit sublimators didn't or couldn't work, don't you think the Soviets would have been smart enough to work this out? Or do you think they were in on the hoax? If so, why would they go along with something which provided a propaganda victory to the USA at the height of the Cold War?
