How The Space Shuttle Works

[CapitanoGUC]

it gonna blow up anyway ....:-)

[Vitaminnn07]

sorry for bad english. but where can we see any video from inside a cabin when the pilot goes from the orbit like at 3:40 and catches the control in the atmosphere.. imagine how complicated and interesting that is.

SHUT UP WITH YOUR WHINEY VOICE

[peniswilly]

spot on mate. true dat

[boomshackalocka]

Sorry - that was a response to untoldmedia, not Aaron518.

Good video. I would have to correct this saying it's friction with the atmosphere that causes it to heat up.Thats a popular misconception. Its actually ram pressure causing the gases in front of the Shuttle to compress,and when you compress gas it heats up.The heat from the compressed gas transfers to the Shuttle,or whatever is falling into our atmosphere from space.

[T3XProductions]

Thanks for the info, I didn't know that.

[BrunsAce]

True, but wouldn't the compressive action and resulting heat be caused by the friction of the (compressed) air molecules? As the molecules are compressed and rub against one another (friction,) the result would be heat..would it not?

So therefore, yours and the original explanation (friction) would be correct...although your explanation digs a bit deeper. ;-)

[djla1]

cool nice job...adding this to my site. is that ok??? pls reply

[micheals1992]

is it true that its impossable to fire a bomb from space?

[Supish16]

yes it would explode b4 it reaches earth

[micheals1992]

so NASA lied about it to get goverment funding in the 60s? cause they said if russia went to space befor them they could fire weapons at them from space

[Supish16]

yes

[untoldmedia]

yes yes

[paulbottomley42]

Why would it explode? Assuming you've shielded it in the same way as the Shuttle, I can't see it detonating prematurely. And there's less chance of a nuclear weapon prematurely going off.

I'm not trying to be contrary, although I guess that's how I'm coming off. I'm just explaining how I think it is possible to fire a weapon from space. Please correct me if I'm wrong.

[djla1]

i think your right. theres people in a craft and thay come down ok..to think about it i bet the us have already tryd it out..shoot a blank down to test.mmmmm

[lllllooooooolllllll9]

ehm ... sorry but i think that the bomb would explode in the atmosphere!

[slopedarmor]

could you make heat shields around it etc, and than guide it through the atmosphere...

[untoldmedia]

I rate they could give a bomb just the same mobility as a shuttle, if they really wanted to, therefore they could get one do a 180 roll to slow it down etc, right? Or are we worried it would heat up too quickly and set off early?

[Falkirion]

For anyone curious about the shuttle on landing. I think thats Columbia but I'm not entirely sure. Landing is definitely at Edwards though

[masterpiecegroup]

tell us smth we dont know...?about the space

[daniel223543]

great vid thanks!

[aviationforever]

WOW nice landing at the end!! i love your videos! very interesting! keep up the good work!

[holon67]

or doesnt work

[thegarlands04]

cool!!!!!!!!!!!!!!!!!!!!

[mikepent03]

my dads a astrunot

[willsd87]

oh dear oh dear, old video! The heat is mostly created by the pressure not the friction...

[lachat2007]

um no sorry its friction.. rub your hands real quick and you'll see they heat up.. pressure wouldnt do that

[willsd87]

ever heard of pV=nRT ? It's pretty much all pressure that heats it up. The reverse of how a fridge works. The nose would be cold if it were friction. Also, blow on your hand...feels cold doesn't it!

[boomshackalocka]

Just to clarify - the heating is caused by the aerodynamic heating of the vehicle during entry. It has to dissipate a tremendous amount of kinetic energy in the form of heat to slow itself as it flies through the atmosphere. Although pressure does play a role in the distribution of heating in hypersonic flow, the pV =nRT relationship (also known as the ideal gas law) does not apply in this situation, because the ideal gas law only applies to closed thermodynamic systems.

[untoldmedia]

Nobody mentioned the gas flow, why bring that up, and then say it doesn't apply here?

[boomshackalocka]

The ideal gas law does not apply to this situation. I referenced it because earlier posts had mentioned the law as an explanation.

pV = nRT only applies when you have a closed system (such as a piston).

[k0nn0r]

Err no. What you refer to is the laws of aerodynamics that only apply in a continuous atmosphere.

[raachaell]

yes it would - PV=nRT so temp goes up as pressure goes up

[Jabbajawz4life]

Yay third comment well all i wanted to say was great Video.

[conboy1234]

nice video

i wanted to get the first repsonse but fuzz beat me to it

[fuzz323]

great vid thanks!
