OK, the Moon is black as asphalt.

You're the only one saying that, at this point. It is NOT black. It is as DARK as asphalt with an albedo of about .12 at it's brightest.
The biggest reason why the moon looks "white" at night is because your EYES and BRAIN adjust the contrast of the image on your retinas. Hence, one of the BRIGHTEST objects in the sky at night - the MOON - appears as the BRIGHTEST object to your eyes... the contrast is changed and it appears white.
For proof your brain did this, look at the moon from inside your house with ALL the lights off. Then, after a few minutes, TURN ON THE LIGHTS. GUESS WHAT? Your retinas get overloaded for two reasons.
ONE, your irises are wide open and can't close up fast enough to compensate, and
TWO, your brain has wired the contrast of the images so that the MOON is near 100%, so the light is WAY too bright for your brain to process.

You want to talk metals? Now you're talking my bussiness. I've got 2500 pounds of my own aluminum handiwork in deap space right now. With a little heart and arrow with me and my girlfriend's initials scribed inside one big piece. You see those C-17 Airforce transports dropping food to the Afganies? I cut the titanium jet tailcones {etc, etc}

I use a computer everyday, but I don't claim to know precisely how the video card communicates with the CPU. So you work with metals? Big deal! You don't have to cut metal to understand the physical properties of it.

I make assertions and have the courtesy, not to mention the scientific propriety, to provide links to official NASA drawings, images and figures to support my assertions.
YOU make assertions and expect ME to do the research to support YOUR assertions.

We ARE doing the research (or have done it) and are presenting the RESULTS to you. You choose not to accept those results. That's your perogitive.
Tsk, tsk, tsk.

I don't think it's too much to ask that if you say the moon is as black as asphalt or a blackboard that you find some pictures from the NASA image gallery, to which I provide a link, containing hundreds of pictures of the Moon from every concievable perspective that you find some that show it to be black. Instead of playing some occult philisophical numbers game.

The photographs of the Moon don't show it to be DARK (NOT black) because in order for it to show up, the CONTRAST HAS BEEN INCREASED TO MAKE IT VISIBLE. The lenses and film speed and exposures used were chosen to make the Moon appear at least as it does to our eyes at night (and in some cases brighter or with MORE contrast). It doesn't help anyone to visually analyse the Moon's surface if they can't see it.
Now - for some images that DO show the Moon as dark! NOW you're talking!

NOTE: The above image's captions states that the Moon's brightess was increased FIVE times for the image.
There have been thorough studies of the Moon's albedo, and they all indicate something between .06 and .12 (or 6-12%). Would you like us to dig up some reference for you to personally look up? I'll try and do so, if you want.

Not that any of that makes a bit of difference to the point that there is no legitimatly supported theory as to why Apollo 13 got cold when enormous expense is invested in throwing a cooling system that is designed to manage deadly heat up there and it "has to be turned off".
|
Apparently you haven't read any of the responses to your questions or you really don't care and are just stirring up trouble.

Heck, calling it a cooling system is to under rate it to the point of idiocy. Once the launch stages fall away the spacecraft themselves are nearly all life support system. And life support means pressure vessel, air and cooling.
