>>16633709>lens didnt shatter from temperature differenceYou need something conductive for that to happen.
-take a wine glass and heat it up with a blowtorch
-drop it into ice water
-it shatters
Now repeat that but replace ice water with nothing not even air. The wine glass would cool more slowly on the moon than it would even on earth at normal air temperature because there is no air. The only way an object in a vacuum loses heat is be radiating it (IR). There is nothing else to conduct heat to “freeze” it. Glass has poor thermal conductivity so it heats up slowly or cools slowly from IR.
The bigger concern on the moon is super heating equipment. The direct sun is exponentially more intense and far hotter than the hottest desert on earth. The surface of the moon was 200F when the “small step for man” moment occurred but the cameras didn't sit on the hot rocks for long, if at all.
Tl;dr
No reason for lenses to shatter since they would only gradually cool or gradually heat up. Its the sudden drastic temperature change that causes it to shatter and there is none of that on the moon.
