If space is freezing cold, how do space suits and satilites not freezing solid?

[Greek_goddess_Iris]

Space is -454°F. Metal doesn't love the cold. It shrinks, cracks and stop working. Humans (even with space suits) should freeze to death in seconds.

Space isn't "-454 °F" everywhere. Not at all. Indeed, satellites and spacewalking astronauts need to worry about the heat from the sun.

I don't have time to discuss this, but, while your question is reasonable, it lacks understanding of some aspects of thermodynamics.

[Ad_Quid_Orator]

Interstellar space is that cold but most of our satellites orbit in the ionosphere where the temperature is 450 degrees F. The reason they and the astronauts don't burn up is because the air is very thin up there and thus the heat transfers from the surrounding environment at a very slow rate.

The only reason there's ice and snow in that picture is because there's atmosphere on Earth, and water and other elements which stress metal. None of those is present in space; it's a vacuum. Study metallurgy and you will see how metal is not affected in space the way it is on Earth.

[Greek_goddess_Iris]

The picture is not a space picture. It's just showing ice on metal to create a visual.

@Greek_goddess_Iris space near earth is still hot,

any spaceship enters earth atmosphere will catch high heat or fire.

thats why all spaceships have heat tiles on them

What I'd like to know is, if there's no air in space, or at least on the moon, and sound needs air to be heard, how did we know the moon rang like a bell a decade or so ago when we bombed it?

The sun is still hot, and I think it keeps those things from freezing up.

[Greek_goddess_Iris]

Picture this, a satellite gliding above earth, half of it is burning in direct sunlight over 250 °F, the other half sits in shadow over - 250 °F. That's a 500° swing every 45 minutes. No cracks, no frozen wires. And astronauts, their fabric suits keep them alive in temperatures that would freeze solid steel.

[WonderingManII]

Did try doing an internet search before asking your question?

Here is one answer I found.

Satellites stay from freezing by using a combination of passive and active thermal control systems to manage extreme temperature changes. These systems include insulating blankets, special coatings, and heaters for warmth, and radiators and sunshields to dissipate or block heat, respectively. They also use heat pipes to move heat from components, and the materials they're made of are selected to withstand extreme temperatures.

No. I want to see what real life people have to say. Otherwise none of us have to post on here ever.

Lol she forgot about insulation

[Greek_goddess_Iris]

I'm quoting what I said to another person. "A satellite gliding above earth, half of it is burning in direct sunlight over 250 °F, the other half sits in shadow over minus 250 °F. That's a 500° swing every 45 minutes. No cracks, no frozen wires. And astronauts, their fabric suits keep them alive in temperatures that would freeze solid steel." Tell me how that steel can survive that intense temperature jump. I don't know of any insolation material that can survive those temperatures too.

[CupcakeTheDestroyer]

Do you know what steel’s melting point is?

[Greek_goddess_Iris]

I stand corrected. You are right. OMG I had the melting point wrong. I'm very disappointed in myself now.

[Greek_goddess_Iris]

The site won't give me the option to give you a "most helpful opinion" today. MHO to you tho.

[CupcakeTheDestroyer]

We all make mistakes, just shows the importance of doing research before posting lol
