An interesting man, this Dr. Ceccato, but I fail to see what he has to do with the conversation at hand. You would be better advised to take the advice of D.A. Filth, who has stated repeatedly that all news is bullshit until supported by emperical fact.

BIGBRAIN I have supplied you with a video of a Neil Armstrong flying a craft that you say cannot fly. Why do you ignore that evidence and try to balance soda cans on your finger.
Are you stupid or something? |

A wealth of Apollo documentation in PDF format can be found at
http://www.geocities.com/bobandrepont/apollopdf.htm
The Apollo CM reentered at speeds of about 25,000 mph, leading to temperatures as high as about 5,000 deg. F (2,800 deg. C) in front of the heat shield.
The heat shield itself is depicted below (from the Apollo CM News Reference):
The key is not what temperature something melts at, but rather what happens in front of the blunt end - a shock boundary keeping the hypersonic flow off the vehicle, and a "stagnation zone" where charred heat shield material carries away heat and protects the vehicle by slowly sacrificing itself. That's why most vehicles designed for reentry are blunt bodies in their direction of travel, rather than having sharp leading points.
The same technique has been used by all spacefaring nations, and astronauts from many countries have been protected by this technology. The idea that heat shield technology is somehow inadequate to reentry is so easily disproven that not even most HBs use it. That's really saying something. |

I see.
Rather like burning a candle then, isn't it. The candle slowly destroys itself, but provides light until it is all gone or no longer needed.
Unlikely as it seems, I'm learning a lot from these ridiculous threads. bigbrain is a very good instructor, albeit in ways that he does not intend.

Hi calladus, and welcome.
These and many other questions have been asked of bigpain over a number of threads each containing a huge number of pages.
I doubt that you'll get an answer, and even if you do, it probably won't make sense.
Many have been chipping away at the stone that is bigpains ignorance, with no discernable effect.
I guess you're right - he didn't answer.
I wonder who he thought Hams (Amateur Radio Enthusiasts) were talking / listening to?
He seems to go on and on over one bit of 'evidence' - his belief that the re-entry of the Apollo capsule would cause it to burn up. But he neglects the tons of correlating evidence, from professionals such as scientists, engineers, and media; and from amateurs in radio and astronomy, that all point to the same conclusion.

You are poor gullible persons. All those coatings are not 1 meter of concrete, 1 meter of rocks, 1 meter of stones, 1 meter of tungsten.
All those coatings form a coating of 7 cm of thickness.
In 10 seconds at 2800 °C that ridiculous coating dissolves, metallic capsule begins to melt and the poor astronauts burn to death.
This is the true scenario.

I have a frying pan which has only 7 cm of plastic between the steel handle and my hand, yet even when heated to the point that the steel imparts contact blisters, the handle is not unreasonably warm to the touch. Even here there are many layers which all dissapate the heat.
As sts-60 has pointed out, the alloy used in the ablative shield was designed to char at high temperatures and come apart so that the heat would be carried away from the craft. In addition, other insulation kept the heat from the outside away from the inside.
So tell me O hydrocephalic one, where is the proof of your assertion? Why shouldn't we just consider your statements craps?
And you try to call US gullible.

The fact that this thread and NoBrains responses are a joke makes you all gullible. As I pointed out 36 pages ago and 20 pages ago, but if you folks wanna keep using him as an excuse to learn about space engineering and astrophysics go ahead.
He is only trying to piss you off folks |

Ooooh, that makes me so angry....! 
He is pretty repetitous, isn't he? Unfortunatly, he lacks the deluded agression of HYBRID or the perverted idiotcy of latinijarl. It's kinda hard to get really ticked of at Bigbrain the Blind. He's simply not obnoxious enough.
Hey bigbrain; get more obnoxious, won't you. We need some vituperation practice.

How much heat can your frying pan produce 
2800 °C

I'll say this again and use small words for you.
The frying pan gets hot and with nothing between the handle and the plastic, my hand doesn't even get too warm.
The Apollo craft used stuff in between the plastic and the people which brought the heat down even more.

What a pity that plastic at 250°C begins to dissolve or to char and then it burns.

BIGBRAIN, I would love to explain to you that the polymer DOES burn off of the heat shield, a layer at a time, but unfortunately you are not capable of understanding any of this because you are stupid or something...
