begins a somewhat "ballistic" entry. You are correct that the series of roll procedures reduces speed, but the major heating occurs with the shuttle still at a 40 degree nose up pitch attitude where, yes, friction does induce heating but since the pressure (and therefore density) of the air is

[sietec]

@puncheex - thanks for the explanations. However, one correction - about 80-90% of the heating that occurs during re-entry is due to compression effects of the atmospheric molecules as the shuttle begins a somewhat "ballistic" entry. You are correct that the series of roll procedures reduces speed, but the major heating occurs with the shuttle ..continued

[pilot7893]

Pardon me. Would you like to explain to me the launch of STS-118 I saw myself from Disney in 2007?

[EvilSlyGuy]

Google LRO! Ignore my childish clone.

[interfaceboyz]

the flame is just remnants of toilet paper burning as it jettisons , normaly you dont see it , but there must have been extra on this particular flight, nothing to worry about...

[smilymez]

The flames are from the APU (auxiliary power unit)

Something has to produce power for this bird to be flyable.

But nice try on the toilet paper...

[astronut68]

there burning off purged gases from rcs i think?

[mach25man]

Pulsing of the APU exhaust is the right answer. Does it every landing until APU power down. Cant see it during the day.

[Jetbomb]

Im pretty sure thats a light, not a flame, but dont let me ruin the moment. :P

[septje]

Actually, it's the exhaust from the APU that powers the hydraulics and flight control systems, and cools the internal systems of the shuttle when the payload bay doors are closed. When the APU is not running, the shuttle internal systems are powered by hydrogen fuel cells.

[maziku]

question: if upon re-entering earth's atmosphere the temperatures reach 3-4k degrees F how do the decals and paint on the shuttle survive? what kind of paint are they using? i only ask because you seem to have good knowledge about shuttles based on your post here. thanks in advance :D

[tehklutzking]

They angle so that the heat plates sheild from the heat and it cause it to only heat up on the bottom and slows the shuttle down.

[puncheex]

@maziku: It only gets that hot on the thermal tiles on the nose, belly and wing leading edges.

[panictactics]

Yes it's an anti collision light. The shuttle uses a candle for this purpose. Clown!

[LFCsteUK]

surely that flame cant be good lol

[panictactics]

Why is the bastard on fire?

[joachim2464]

it is exhaust from the APU system

[indigochild79]

That's not a UFO

[justjayok1]

Are you sure?

[indigochild79]

LoL

[justjayok1]

Looks like a flying twinkie.

[indigochild79]

Yeah ..you know..it could be ..never trust the gouvernment space bakery program LoL

[justjayok1]

Mmmm... Bakery program. I wonder if they could create a race car out of donuts.

[indigochild79]

MMmm donuts (Homer sound)

I must confess i would be a little surprised if i ever saw a school bus made entierly out of chocolate pie *LoL*

[justjayok1]

From 0:20 - 0:50 is does kinnda look like a cupcake with a candle in it falling from the sky.

[justjayok1]

0:57... Oh sh*t! The Canadian robots are going to space now. I always knew the first cyborg wars would be against Canadians. I have a hard time trusting people that are just so darn friendly all the time.

[indigochild79]

LoL maybe Jehovas wittnesses are cyborgs? Cuz they are awfully friendly ,,

[justjayok1]

Ooo, good call.  Maybe they brought back Jesus with them.

[ZaneKaminski]

We put your satellite into orbit... It was launched on an American rocket.

[simonsin666]

mmmm twinkie.....

yummy

[Maisy5]

EXE - are you serious?? Do you have any idea how many things you use on a daily basis are a result of the space program?? Good grief, get your head out of the sand.

[cr8zyy]

This comment is for EXE. Where do you think all the money spent on the space program goes? What is the true value of items actually sent out into space?

Here are the answers....

The money spent on the space program goes to NASA employees who in turn spend it right here on earth. And the money that is "wasted" (according to you) is just the value of all the raw materials used to build the spacecrafts. Everything else is just a stimulus to the economy along with benefits of all the research.

[NelsonXVCT]

Could of just reply to him..

[indigochild79]

Obvious fake..Its a weather balloon i see them all the time..

[justjayok1]

Swamp gas.

[indigochild79]

LoL ..yeah

[Glassblower718]

good job !!!

[EXEcutioner1966]

What good is the research going to do? Invent some new medicine that people will never get because they can't even go to the hospital to find out they need it. And if they manage to make it to the hospital they will never be able to pay for it. Satelites are the only thing space is good for and they can be sent up by unmaned rockets. We are already making people live longer then is enjoyable. My company has to take care of these living dead. They request death on a daily basis.

[EXEcutioner1966]

I don't think I would want to ride on something that lights on fire half the time! The country is supposed to be broke, where are they getting all the money to keep wasting on this crap. 40% of the citizens can't even afford to go to the hospital when they are sick and they are losing their houses but there seems to be plenty of money for these people to keep playing star trek. Go figure. They use this like national nascar to distract us from the fact that we are screwed.

[Volodus]

You think they play chess up there? Type "International Space Station (ISS) Research" and read ...

[Volodus]

Type into google*

[joachim2464]

actually they played chess up there:) But the ISS is an important outpost

[adamP90X]

why can't they land this thing in clouds? Can they not shoot an ILS approach?

[tudmandog]

they are burnoffs

[DgenerationX12345]

It's on fire.

[Hello3427956704]

My dog's breath smells like dogfood

[adamP90X]

and shit

[trufflepyg]

Does anyone know what the flames are seen at the beginning of the video (and hinted at during the landing rollout?)

Thanks

[sledger25]

those flames are the burn off of the Auxilary power units

[AreaQNH870]

my cats breath smells like cat food

[92GH]

btw, y r NASA retiring the shuttles?

[Jralvan07]

cuz they have already more than 20 years working

[MsIanAstbury]

that is not why......the shuttle has exhausted it's use, the USA is moving on to MARS etc....We have fulfilled our obligation contractually to the Space Station. As always the USA is looking forward.....

[tornadomanatwork]

think dude 14 lifes lost .there getting old

[joachim2464]

what is fake?

[raptoresque]

lol he thinks its a ufo

[joachim2464]

some people just don't got a clue, hehe

[fearlessrr]

Check out my site for a nice ufo i filmed last sunday!

[w5cdt]

Check out the flames coming from the hydraulic APU's. I knew you could *hear* the APU from outside the shuttle but I didn't know the hypergolics acutally had a visible flame.

[4izm0v]

awesome!

never gets old no matter how many times I watch it!

[horndog691]

I agree its about time someone know what their commenting about apu venting. I love 2 c the space race continue. I look forward to a new space era. Bring it on nasa I am waiting.

[esxp]

if McC wins you are NEVER gonna see it!

[horndog691]

why is that? will it be any better if the big O wins.

[chef2lare]

los felicito acen buenos trabajos allaarriba en el espacio

[DukeOnkled]

something tells me that Endeavour will be delayed due to the tail on fire on the ground...

[Perkelenaattori]

That's actually normal. Just shows a lot better because of the night landing.

[jameskennedy80]

good old fashioned air friction does the job, firstly when it reenters the atmosphere, which slows it down a lot, then as it makes a number of high altitude turns to reduce speed further. That said, it still lands a lot more quickly than other aircraft.

[tomanyasses]

go nasa lets get into outer space go go go

[kyrkbymannen]

She's a beautiful thing..

[EndeavourLaunch]

Actually, its APU Venting, there on every space shuttle and Airplane.

[Ladco77]

Someone who knows what they're talking about. How refreshing. :)

[Kylenator]

Just a question I'd like to ask. How does a shuttle slow down from the high speed of re entry to be able to land like a normal aircraft does? I'm a little green with shuttle re entry procedures so it'd be cool if you could help me out haha.

[puncheex]

@Kylenator: The main thing is the resistance of the air as it descends. That translates into the heating up of its surfaces. It also does a series of roll maneuvers to increase the air resistance. It lands like an airliner, except it has no power to climb out, and it descends about ten times faster than a jet. The two surfaces at the back of the rudder (speed brakes) flare out, the landing gear and parachute further slow it. Once its on the runway it uses brakes on its wheels.

[puncheex]

Forgot. In orbit it uses the OMS (orbital maneuvering system) rockets to slow itself enough to start the descent.

[sietec]

@puncheex - thanks for the explanations. However, one correction - about 80-90% of the heating that occurs during re-entry is due to compression effects of the atmospheric molecules as the shuttle (continued)

[sietec]

@puncheex (cont) begins a somewhat "ballistic" entry. You are correct that the series of roll procedures reduces speed, but the major heating occurs with the shuttle still at a 40 degree nose up pitch attitude where, yes, friction does induce heating but since the pressure (and therefore density) of the air is

[sietec]

@puncheex (cont) so low collisions with air molecules are not too rampant as they would be at a lower altitude. The compression of the air in front of the hypersonic shock wave heats the fluid to a "plasma" state. Again, thanks for helping educate people on the space program!! It is so important that we have support to continue it!

[sebahattineglence]

mekikmi bu ne arkadaşlar

[Niven42]

I was there when it landed!

Here's the scoop on the program:

Last shuttle launch/last manned flight from KSC = 2010

First launch of Aries (shuttle replacement) = 2015

First manned landing on Moon of the 21st century = 2020

...If all goes well. A NASA rep says this is a very likely scenario (as of 3/27)

[SexyToshi]

Whats that little fire coming out? Did shuttle shit itself?

[terencefooyc]

that fire is the outcome of the space shuttle bursting through the stratosphere.

[Nickhansen1992]

actually thats one of the many small jets that spacecraft have change their trajectory just before re-entry. they also use them when in space to allow for small changes in their direction. so its basically a complicated steering wheel.

[puncheex]

No. Its the APU exhaust; it throw off hydrogen which is burned. The APUs provide power to the hydraulics on the shuttle and for other uses. You can hear it chugging after the landing, and also in the last minute before launch.

[stvoodoo]

Pretty sure she said "Shuttles" not programs

[Harkins1721]

So wait they building different type shuttles then?

[leslie12180420]

WHOA......they are retiring the space program in 2010!!!! thats not even cool

[blastergangsta]

......did the space shuttle ever stop?

[ripleymanwithscanner]

shit
