Who can explain the science behind the ASTRONAUT'S SPACE SUITS?

Explain. Links?


And yes, the space station is in the UPPER ATMOSPHERE, NOT SPACE like the moon. Just thought I would clarify that.

So you're telling me that the suits use radiative cooling now?

[link to en.wikipedia.org]

How does their oxygen not get sucked out into space?

You really are that lazy aren't you? This is basic high school stuff.

Wow, YOU ARE LAZY.

"Thermal radiation is generated when heat from the movement of charged particles within atoms is converted to electromagnetic radiation. Solar radiation heats the earth during the day, while at night the earth re-radiates some heat back into space."


You compare this to an astronaut in a suit???

HOW CAN AN ASTRONAUT IN A SPACE SUIT IN THE BLAZING SUN RADIATE OFF HEAT??????

LADIES AND GENTS:


WILLIAM COOPER:

NASA claims the spacesuits were cooled by a water system which was piped around the body, then through a system of coils sheltered from the sun in the backpack. NASA claims that water was sprayed on the coils causing a coating of ice to form. The ice then supposedly absorbed the tremendous heat collected in the water and evaporated into space. There are two problems with this that cannot be explained away. 1) The amount of water needed to be carried by the astronauts in order to make this work for even a very small length of time in the direct 55 degrees over the boiling point of water (210 degrees F at sea level on Earth) heat of the sun could not have possibly been carried by the astronauts. 2) NASA has since claimed that they found ice in moon craters. NASA claims that ice sheltered from the direct rays of the sun will NOT evaporate destroying their own bogus "air conditioning" explanation.

Remember this. Think about it the next time you go off in the morning with a "vacuum bottle" filled with hot coffee. Think about it long and hard when you sit down and pour a piping hot cup from your thermos to drink with your lunch four hours later... and then think about it again when you pour the last still very warm cup of coffee at the end of the day.

No Ignatz... I did not compare it. You asked an inane question. I answered that.

If you can't deal with it, I'll just go read other threads since yours has fallen to the realm of idiocy.

YET AGAIN THEY GIVE UP BEFORE GIVING ME AN ADAQUATE ANSWER.


TRY TO DEBUNK THE LINK BY COOPER PLEASE. PLEASE EXPLAIN HOW IT WORKS. Or stfu because you don't belong in this thread.

Lets test a space suit in BUZZ's mouth because I can attest that he can make one hell of a vacuum!

How many more people are going to avoid this question with their innane commentary?

OP WINS!

Do they carry some water around, boil some of it, and then release the steam? That would let them get rid of heat. I read that on a thread around here somewhere.

But isn't the temperature on the moon's surface in sunlight, above the temperature that water boils at sea level? So where do they get the cold water from?

How long would it take to boil 12 pounds of water if you put it in a pot on a stove, at the same temperature as the moon's surface?

i thimk its called pressure .vent to a vacum easy vent to 1000 atmospheresa little harder.oh om scuba.oh heatexchangers

The Apollo mission A7L spacesuit.

YAWN!!!!!

Try again Apollo deny-tard.

The ISS is at about 220 miles above the Earth. The edge of the atmosphere is usually said to be about 62 miles. To get the picture of the Moon through the atmosphere, they just had to find the Moon rising from behind the Earth.

The unexplained cooling system is the smoking gun.

It's not unexplained.

It's just that most everyone is too damn lazy to find out about it. Including yourself apparently.

The backpack they wear with the suit has water in it. Frozen due to the temperature.

They use an ice sublimator which drops the pressure in the ice container. Causing the ice to turn directly into steam. Steam is ANY water in gaseous form, it does NOT need to be hot.

That is circulated into a layer of the suit, then back out into the ice container where the coldness of space refreezes it.

Can an astronaut have a heat leak into a vacuum?

Moon Landing Hoax Apollo 16 : Houston Hints That The Astronaut's Space-Suit is Not Pressurized
[link to www.youtube.com]

Houston Hints That The Astronauts Space-Suit is Not Pressurized & Has A Heat Leak.

Astronaut Charlie says at :11 "Look at that rock over there John, if that's not a crystalline rock, I'll Depressurize right here."

Houston replies at :21 "I wouldn't bet on that Charlie."

Astronaut Charlie says at :35 "Oh heavens, I can feel a Heat Leak."

Houston replies at :40 "We caught you with your fly open."

People here seem to have the 'I don't understand it, therefore it can't be true' mentality.

WOW<GOOD POINT not NOT!!!!


how does your car radiator keep from depressurizing into the air?


DUH

But what about on the moon in the daytime? The temperature on the moon's surface is over 100 degrees celsius. That's hot enough to make water boil at 1 atmosphere pressure. How is the water refreezing on the surface of the moon in daytime?

It's in shadow.






I mean, really....look this stuff up. It is EASY to find out about the coolant loop on the A7L. And the math is easy-smeezy too; anyone who passed high school chem can work out from heat of vaporization how much cooling you can get from a pound of water.

Here's first approximation for you, though. Suit is white and in a vacuum. Consider it isolated from environment; most of the heat input is from the astronaut inside. The problem is how to reject that metabolic heat.

Then could one of you shills answer the question? How does the AC/heater work in a vacume?

The vacuum of space is cold the heat of the sun is hot plus they wear undies plus they hooked up to a temperature control unit.

Works out okay really!

Yes, the SURFACE was that hot. No atmosphere though, so that heat could only affect whatever was DIRECTLY touching the surface...during the daytime.

Since only radiation remains as a method to transfer heat energy in a vacuum, just a properly colored coating would keep heat from the interior of objects...including the backpack.

Why do you think practically everything that goes into space and contains a human is colored white? It's not just cause it looks cool.

Yall needs ta lern how ta spell vacuum furst!

P.S. properly colored as in a color that can reflect sunlight.

You don't have to directly touch the surface of the moon to get heated up by it. Just like you don't have to touch the surface of the sun to get heated up by the sun. Think about it please.

Your taking your experience on the Earth (has atmosphere), and trying to apply it to the Moon (virtually no atmosphere).

Thinking about it yourself, instead of acting like a condescending dipshit who thinks they have won an argument.

At high noon the average temperature of the lunar surface can reach that temperature. But that's not the same thing as saying it was 72 F (22 C) in Los Angeles today. The latter is air temperature. The temperature of various surfaces in Los Angeles might have been as high as 180 F (82 C). Air temperature has no meaning on the moon because there's no air.

280 F (138 C) may be the temperature of the lunar surface material at equilibrium in full sunlight, but it's not the temperature of any random object in a similar situation. Objects will be heated to that temperature only if they absorb the same amount of sunlight as lunar surface material, and also radiate it at the same rate. More reflective objects absorb less light and are heated less. Less reflective items may be heated even hotter.

Air temperature is not the same thing as surface temperature.

Just as on earth, the temperatures at morning and evening on the moon are lower than at noon. This is because the sun strikes the surface at a more acute angle and therefore isn't as intense. The lunar landing sites and times were chosen so that the astronauts would be working there in the early morning before the temperature had risen to its hottest. This reduced the surface temperature at those sites.

The physics term for this phenomenon is "form factor for radiative heat transfer". Quite a mouthful. The meteorological term is "angle of insolation" and it's why we have seasons on earth.
