It's hard vacuum on one side. There's a reason the word "hard" is used to describe it. A few years ago a Soyuz was improperly drilled during manufacture. This was patched with a super epoxy... and then began leaking air on orbit. Paint won't seal what a super aerospace epoxy failed to seal. | ||

> There's a reason the word "hard" is used to describe it. Because it's more extreme. Do you think a soft vacuum of 0.002 atmospheres of pressure would be notably easier to prevent leaks into? > A few years ago a Soyuz was improperly drilled during manufacture. This was patched with a super epoxy... and then began leaking air on orbit. Paint won't seal what a super aerospace epoxy failed to seal. Wasn't the fix on the ground a secret patch by the person that drilled the hole? I don't trust that to have been done properly. And then when they noticed it was leaking... they used the super aerospace epoxy. Which was labeled as temporary but as far as I know it's still the fix. Also that was a serious hole, 2mm wide, not a microhole like you'd try to fix with paint. | ||
