AS-204 rocket where 3 astronauts died in a “fire” in 1967

Houston. It’s starting to get hot in here.
Negative John. You mean cold right?
No, no… it’s getting damn hot. Crazy damn hot!
Don’t worry Captain we wrapped layers of aluminum foil around your capsule. It should peel off and repel the heat.
Houston… I… Arrgh.. (choke) it’s too… much… unbearable. I ca…
Those were the last words spoken by poor Captain John Doe, guinea pig for NASA test flights as the blood boiled, his brain expanded cracking his skull open, while his body fat melted on to the red hot glowing chair. What was left of his suit combusted on the spot
and then started to mix with the now molten metal of the instrument panel.
The whole rocket had exploded seconds before creating a beautiful white glow in the now 1500 degree heat. What was left of John, his suit, capsule and rocket gelled into one molten mass and fell back to earth as NASA’s first inadvertent attempt at making a man-made meteorite.

This fictitious account of early “space” travel is probably closer to the truth than NASA care to admit. There is a teensy weensy fact that makes a complete mockery of the Hubble Telescope, the International Space Station, satellites and nearly any other object which they claim orbits the earth. This fact can be summed up in one word:



Thermosphere At about 85km altitude temperatures start to rise until they hit the Kármán line which is 100km high. After this line, the heat abruptly increases rising rapidly to 200km whereby it starts to level off, although other sources say it continually rises. Temperatures can vary, depending on sun activity, but can reach as high as… wait for it…

2500°C!

I kid you not.
In case you don’t know how hot 2500°C is. Your oven in your kitchen can hit 240°C max. A ceramic laboratory oven for jewelers and dentists to melt gold can reach 1200°C. Temperatures in a blast furnace for melting iron can go as high as 2300°C.

ceramic laboratory oven – 1200°C

blast furnace – 2000 to 2300°C

The only elements in the periodic table that can withstand 2500°C are carbon, niobium, molybdenum, tantalum, tungsten, rhenium, and osmium. Except for carbon, these metals are very, very heavy and are of course extremely conductive to heat and most are very ductile when heat treated meaning they bend and coil. Carbon even has the highest thermal conductivities of all known materials! So, if you want to cook someone very efficiently and quickly, there is nothing better than a space capsule made out of graphite.
Now, admittedly, it is not always 2500°C. In fact the temperature range is usually between a mere 600 to 2000°C! depending on sun activity and if it is day or night, with these temperatures usually reserved for altitudes of 300km and above; the upper boundary of which is unknown.
Now guess what altitude all the NASA machines are supposed to orbit Earth?

ISS – 330 to 435km

Hubble Space Telescope – 559km

satellites – 120 to 35000km!

We are told most satellites orbit the Earth at altitudes of over 500km to avoid atmospheric drag, with a few circling in Medium Earth Orbit which goes up to 35,786km!
As you can see, all three objects above are in the seriously ferocious hot zone. Apart from nothing working at the minimum 600°C due to thermal expansion of the materials (iron glows red hot at 500°C), some of the electronic components like lead, zinc, and epoxy resin would not just burn out, but melt.
The solar panels which adjorn these machines would barely function even if they could keep it together long enough. A British company found a drop of 1.1% of peak output for every increase in degrees Celsius of photovoltaic solar panels once the panels reached 42°C, and of course at 1414°C silicon actually melts. But wait… the Hubble Telescope and satellites uses gallium arsenide instead of silicon which melts at an even lower temperature of 1238°C. I could go on, but you get the picture.
So how do those solar panels work? How does anything work and why do satellites, the Hubble Telescope, ISS etc. not melt during a day of high solar activity?

NASA’s blast furnace-proof International Space Station

Aha, don’t worry, I’m sure the apologists have come to the rescue of this laugh-in-your-face contradiction; and they have, or rather have tried. Excuse number one comes from a few websites such as Wikipedia who wish to insult our intelligence to the max. Here is the main explanation for why satellites aren’t converted into man-made meteorites:

The highly diluted gas in this layer can reach 2500°C (4530°F) during the day. Even though the temperature is so high, one would not feel warm in the thermosphere, because it is so near vacuum that there is not enough contact with the few atoms of gas to transfer much heat.

Errr… wait a minute. I thought it is the sun that causes those few atoms of gas to heat up to 2500°C? Oh, it is.

Thermospheric temperatures increase with altitude due to absorption of highly energetic solar radiation.

So, do you think if NASA put a Hubble Telescope up there, it also might absorb highly energetic solar radiation exactly like those few atoms of gas to a maximum of 2500°C? You think!!!!

The source of the heat of the thermosphere is not a few atoms of gas.

It is the sun!

You know, you may have heard of it, or seen it or even felt it? Ask this man if he believes in solar radiation.

“Wikipedia said what?”

Even NASA themselves admit this in their question and answer session at question 3:

Heat travels through a vacuum by infrared radiation. The Sun (and anything warm) is constantly emitting infrared, and the Earth absorbs it and turns the energy into atomic and molecular motion, or heat.

So much for that excuse. They realize that there will be a few multi-cellular brained human beings out there that will see straight through this, so they’ll need reserve explanations. Enter Dr. Eberhard Moebius at question 5. who says,

…this is the second secret of the vacuum bottle (or thermos): while the vacuum suppresses heat exchanges by conduction and air convection, exchange by radiation is suppressed by the shiny metallic coating of the bottle. This shiny coating reflects the heat radiation like a mirror and keeps it either inside the bottle (if the content is hot) or outside (if the content is cold).

But none of NASA’s orbiting machines are completely covered in a layer of IR reflecting materials, only a bit of aluminum foil for the Hubble Telescope. Even if the foil could withstand 1500°C radiating heat, it certainly wouldn’t be able to stop conducting the heat from the the other materials of the telescope, especially those lovely infra-red absorbing dark areas, copper foil, plastic coated wires, and tarnished metal; and how about that same aluminum foil reflecting light back onto the telescope itself! Solar cooker anyone? There is so much wrong with the picture below that it is beyond words:

Dave, why haven’t we vaporized into white hot piles of meteoric ash?
Because we are in a swimming pool, Ivan.
Ah, for a minute there I almost forgot.

Not only that, even if the machines were hermetically sealed in IR reflecting materials, there would be nowhere to radiate this heat away as according to Dr. Christian the heat in the thermosphere is always there. There is no colder place for the heat to transfer to (second law of thermodynamics).

…thermal radiation is always there, and that is what a spacecraft uses. To get rid of heat, you can point thermal radiators at the dark sky, and to warm up you can point at the Sun or Earth. The Sun warms the Earth through radiation, not convection or diffusion.

I think it is only fair to give Dr. Christian some slack. He’ can’t be right all the time. Let’s say thermal radiation isn’t always present, even though during the day the sun is continually radiating everywhere. How cold must the other side of the orbiting machine be, and how thermally conducting its material to allow its temperature to keep a low equilibrium after one side is being blasted with a constant, say, 1200°C heat?
Quite.

How the Hubble Telescope would look at 1200°C!

Engineers testing an array of possible Hubble Telescopes for thermal expansion at 500 to 1000°C.

That is the end of NASA’s orbiting machines, or is it? How do we know the thermosphere exists at all? It isn’t verifiable and it isn’t observable by any means.
The problem is, why would NASA lie about such a thing when it completely disproves their portrayed fantasies of the last 44 years.
What’s more, why bother spending years researching, equipping and continually improving the entire body of the space shuttle with insulating tiles that can resist 1260°C? Surely, the previous Saturn rocket’s insulating technology was more than adequate, as it had sent men to the moon… ahem. The rocket’s insulation relied on a process called ablation which just means as the metal layers peeled off from the heat it released the hot gases trapped inside which cooled the rocket down… except it didn’t, as the heat is ever-present in the thermosphere.
Oops, never mind.
The shuttle is the only vehicle that can enter the thermosphere, albeit for short durations and not too high, probably not beyond 300 or 400km. It’s also really risky business; lose a few tiles in one place and the show is over in one magnificent fireball finale. Ask the poor crew of Columbia.
Below is what the shuttle looks like in space as 1000°C heat is applied to it. Notice how the tile glows white.

Real protection in the thermosphere

Apart from unequivocally now proving that the first man in space and return alive, at least traveling above the Kármán line, was only accomplished in 1979 with the development of the space shuttle, there will always be people whose conscious minds still won’t be able to absorb this mind-wrenching truth. Questions will arise such as, what about those beautiful pictures of the Hubble Telescope? What are those white dots I see passing by in the sky once in a while? How can my mobile phone/internet/GPS work? I’ve seen “amateur” astronomer pictures of the ISS, how come? What about those videos of astronauts in the ISS? Why would NASA go to such elaborate lengths to deceive us?
Let’s answer each of these questions one by one in part two of NASA’s weird and wonderful orbiting machines.
