This guy's another poor researcher who thinks he's the smartest person on the planet. If he can't figure something out in a few minutes with no research, then it is unsolvable for teams of dedicated professionals with advanced, specific training and months (if not years) of focused efforts to address that problem. Right.

First lets look at the Space Shuttle. A big problem of the shuttle mission is heat from exposure to the sun. Keep in mind that the shuttle is in earth orbit and therefore is in the earth’s shade 50 % of the time. And STILL, heat is a major problem during the shuttle mission. To divert heat, the shuttle is turned upside down, so the protective ceramic tiles underneath deflect the heat.
|
Just completely wrong. Yes, heat from the sun is a problem for the Space Shuttle, but the tiles have nothing to do with that. Rather, the radiators that are attached to the inside of they payload bay doors are used to reject the heat build up from the sun and the heat generated by all the electrical systems and biological sources (a.k.a. astronauts). The astronauts open the payload bay doors right after reaching orbit (IIRC 30 minutes) and don't close them until just before reentry.

And traveling in the vacuum of space the heat has NOWHERE TO GO! No air to take it on! Space is a vacuum and a vacuum does not have a ‘temperature” because heat requires matter, thus, space itself cannot be ‘hot’ or ‘cold’.
|
Heat does too have somewhere to go. It's called radiation. Yep, heat transfer doesn't just occur by conduction and convection. Radiation is how the sun's energy gets to Earth or to the spacecraft. It's also how the spacecraft keeps cool.

How do you cool a car’s engine? With the radiator. Where does the radiator dissipate the heat to? The air. Put the car’s radiator into a vacuum and the engine will overheat.
|
A car's radiator is misnamed. It's really a convection cooler. Radiation is only a component of how it rejects heat - when you're driving you have air being forced over the heat exchanger.
And what does a car's engine have to do with a spaceship? Why does he assume the two should work the same?

Another unanswered question: Where does the backpack of the astronauts dissipate the body heat to when there is no air to exchange it into? Liquid maybe?. But that will not effectively get rid of the heat either….
|
Unanswered question? Who did he ask? How hard did he look for the answer? Answer: sublimation. Yep, it's called "phase change" in chemistry. You know, "latent heat". Any chemistry I student should recognize that term.

Ok, so they got into the lander, shut the hatch and pressurized the lander, therewith enabling them to take off their boots which were part of the pressure suit. So far so good. BUT THEN they opened the hatch again (with their boots off = unpressurized suits) and threw out some stuff! The resulting decompression should have killed both of them ON THE SPOT!

Here I'm willing to cut him a
little slack. Aldrin is not at all clear in the quoted statement:

We removed our boots and the big backpacks, opened the LM hatch, and threw these items onto the lunar surface, along with a bagful of empty food packages and the LM urine bags.
|
That's not exactly explicit about the suit specifics, and does not make clear there are two layers of boots. However, he cut his own rope (nevermind the slack I gave him) because he makes no effort to find out the answer, despite
having a picture of the suit on his page that shows the overboots. So obviously he found some information on the suits, enough to compare the Apollo design with the Shuttle design. Therefore, he should have pondered why the Apollo picture shows boots on the suit
and/ lying next to it.
Okay, I just looked around further at that site.
