Fairly obvious that you missed the sarcasm aspect of my reply...
The evidence of a moonlanding happening is only blindingly obvious to anyone with eyes to see with, and ears to listen with, and more than two brain cells to rub together to form a coherent thought.
The moonlanding hoax, on the otherhand...is foolishness writ large. I've looked at the so called evidence on a number of occasions and each time am less and less impressed by the psuedoscientific claptrap passed off as evidence.
In fact, temperatures on the surface of the Moon swing wildly from one extreme to the other, from an average of -184°C (-300°F) in the shade to an average of 101°C (214°F) in the sun,
The outer surface of the 500EL data camera was colored silver to help maintain more uniform internal temperatures in the violent extremes of heat and cold encountered on the lunar surface.

source? im not saying you're wrong; but wouldn't the same light that is heating the surface of the moon, heat the camera as well?
You can dance around in the sun on a hot day all you like, you won't get any cooler unless you stand in the shade.
Were the cameras coated in a reflective material? That would make some sense
Originally posted by jra Yes, but the lunar surface stays in the sunlight constantly through out the lunar day (which is 27 Earth days). Only by noon, does the surface reach its peak temperature. The Apollo missions all happened durring the Lunar morning, so the surface temperature wasn't that high.
Also, different materials absorb and reflect heat and different rates. So not everything will heat up equally.
Well, one part of you is always in the shade. What ever part of you isn't in sunlight, is radiating whatever heat it absorbed before. You don't need to be in complete shadow to cool down.
Silver is reflective.

It's just hard for me to believe that cameras back then could have stood up to the temperature high and lows, even if they were cut in half.
If you're in a closed system, you'll never cool down. If you're in an open system, you'll maintain you're temperature if the amount of heat being absorbed equals the amount of heat being emitted. They were in an open system, so yes, if the sun was leaving, they would slowly cool down but eventually freeze. If the sun was arriving (as you state it was) they would slowly heat up.
