Space Shuttle Columbia Disaster Pt 5: Heat resistant tiles | BBC Studios

[@FCPWHAT]

Why was it necessary to split this episode into a load of 2 min videos?? Bloody annoying!

[@hawkeye6038]

FC WHAT ikr

[@therealb888]

Lol true

[@GreatGreebo]

FC WHAT Right?!? FFS...Just show the bleeding video in one piece

[@YarmFaoJor]

They uploaded videos 10 years ago. It had low internet speed.

[@brianfoundamelia9476]

I guess they had the freedom since it's their channel....that's all that matters.

[@Alex18442]

Did anyone else just watch 2-5? Thanks KZbin..

[@einatschwarz5121]

Such big tragedy. I remember I watched it live on tv and they brought Ilan Ramon's father to see The landing live. It was so sad. His family suffored for more lost after that:in 2009 his older son wanted to be pilot like his father but he died in plane crush and Ilan ramon's wife passed away in 2018. Such amazing and strong woman. Sorry for all the families who lost their loved once in this tragedy😢

[@clutch5011]

People are still searching for debris of this documentary. Part 1 is still missing.

[@djolivierastro]

haha epic

[@woodster909]

2 minutes episodes - which bright spark had that idea??

[@TifSC]

When these were uploaded, you could only post short videos.

[@boiragirules]

Oh where is the full version of this documentary.

[@visca_el_barca_2018]

Nowhere

[@turmat01]

by the way the white portion of the shuttle is not ceramic tiles. The ceramic tiles are the black part on the belle, a bit around the nose, and some othe spots. The white parts are fabric actually. The gray-ish parts on the edge of the wings and the nose cone are indeed a layer of reinforced carbon-carbon.

[@alison2649]

Man! KZbin has changed their rules a lot since this was first uploaded into many short vids… I wish someone would reload this video in one full video. Frustrating

[@JustAThought155]

BBC Studios, I’d pay to see the full episode, really.😔

[@andikardian9014]

i searched each part from pt 1 before i watched the 2nd part which was recommended by KZbin.

[@TommyRayzer]

This is probably a stupid question but why did Shuttles have to return to earth at such a rapid rate? Couldn't they do it slower? Using engines to slow their decent or simply continue to orbit and reduce their altitude at a slower rate?

[@junnrhillgailanan3429]

Well, the fast reentry isnt really a matter of choice, the space shuttle used most of its fuel in the launch sequence, the remaining fuel was there only for minor course adjustments, at reentry all of the space schuttles fuel had been depleted. Even if they did have enough fuel to slow it down there would simply be not enough time to turn the space shuttle around to fire its engines and turn around again for reentry. But im no scientist so idk really

[@Kvz2011]

I wont sub until u upload the full vid!!!

[@abefroman9135]

Part 6? Anybody?

[@sellingacoerwa8318]

It exists, it's been sub-edited into 1,373,994 videos each .0023 seconds long and you need a radar gun to detect them. That's why you cant see Part 6 with the naked eye.

[@2enjoihsu]

hahahahahaaha

[@phoenixshade3]

One wonders why the description does not have links to all 6 parts, but Britain being Britain, that would probably be a jailable hate speech offense.

[@jflopezfernandez]

I think it might be this one kzbin.info/www/bejne/aJa3g5SAfKmYY5o

[@barn8793]

I seen all of them except part one lmao

[@Gbrodgersfan45]

@sammyaff the material is to heavy for the whole shuttle, they not only used the carbon for the heat that the wings took upon reentry but for even weight distibution as well

[@tristanlange2428]

Who was the Muppet that thought 2min videos was a good idea? lol..

[@DerOta]

Where is part 6

[@KiwiHobbitful]

Celsius of Fahrenheit? Unbelievably shabby that they fail to specify.

[@garethwest9069]

Yet ppl still think that interstellar space travel at the speed of light is possible? lol.

[@jameshackintosh]

The red coats left a debris trail of this "documentary" across the youtube platform. What with their ALU.....MEN....IUM, trousers, and 2 minute video chunks. In the United States, we use Transparent Aluminum for entertainment purposes.

[@SevenDeMagnus]

So sad.

[@arkzbh]

And nobody can find next parts.. Dead end.. Good job KZbin

[@brianfoundamelia9476]

That material may have been "hard as a rock" but that will result in a brittle fracture if it's a thin body with no ductility.

[@arunkrish3915]

Is this the real footage?

[@susancain9193]

I agree 👍👍

[@barbarjinks8170]

Space craft should have a cast shell rather than a tiled one. Make it all one piece.

[@mklik4]

Weekdays with pt 6?

[@Mohibor]

I'm not good at science, but could they re-enter the earth at lower speeds to prevent excessive heat?

[@LordExtrasus]

no, lower speed means steeper angle, which means higher speed... more heat in shorter re entry time, means your spacecraft will burn fast... however a more flat re entry angle, means more speed and more time spending in the heat, more time to burn down your spacecraft... and i guess slower re entry.... but dont listen to me, i am not a scientist

[@almostfm]

@@LordExtrasus Actually, you've got the basics right.

[@Hale-Bopp]

No they can't it's the earth gravitational pull that makes the shuttle reentry at high speed.

[@dare-er7sw]

@@Hale-Bopp The shuttle is at high speed in order to orbit the Earth. The deorbit burn slows the shuttle by 200 something miles and it's enough to make it reenter the atmosphere. The shuttle at this point is travelling between 17 and 18 thousand miles per hour. They then bleed off all this speed in order to land in Florida. There's no slow or high speed here. The shuttle is at a fixed orbital speed when it enters the atmosphere and starts to slow down for landing in Florida. Its speed is just above 200 miles/hour when it makes contact with the runway. It generates so much heat during reentry as the kinetic energy is converted into heat energy.

[@jamesbuchanan4414]

Reducing velocity prior to re-entry means carrying fuel/reaction mass. The shuttles carried just enough to slow their velocity to the point where their orbit path dropped deep enough in the atmosphere to catch air. The kicker with orbital mechanics, when you slow your vehicle, you lower your orbit's lowest point. The shuttle faces a two fold issue. One, carrying more fuel means more mass, means less payload into orbit, and they're already at a premium, because of all the extra weight they have to carry. The wings and vertical stabilizer are basically dead weight until it's gliding. Secondly, the shuttle needs to come through atmospheric re-entry with enough velocity to glide to the landing field. If it slows down too much coming through re-entry, it loses aerodynamic lift, and ends up short of the runway, or it comes in at too steep an approach angle. It already has all the glide characteristics of a winged brick, the margins are just too tight to risk lower speeds on re-entry. It has to hit the denser atmosphere at a certain speed, with a predictable level of velocity loss to come through entry interface (the burning/plasma blackout part) of the process with enough velocity left to make it to the runway at the right angle of approach, so as not to collapse the landing gear when it touches down, or just belly flop with a loss of vehicle and crew.

[@Nazkyr]

@JoanCollins2009 Carbon-Carbon is a composite material consisting of carbon fibre reinforcement in a matrix of graphite, so theres the Carbon (fibre) and Carbon (graphite) :)

[@davidwiliamson7251]

they have reverted back to the older configuration design space craft which is more aerodynamic than the shuttle. too many lives lost , too much money lost. there needs to be a purpose for all this.

[@ioulolo19]

I know we currently live in a world where people can’t watch a video for more than 7 minutes but come on

[@wololo10]

How they expected that these thin carbon walls would survive that

[@rajeshjena4895]

it's really horrible,

[@timcue5039]

As they were descending the shuttle was basically on fire melted😢

[@lizkinnear8570]

Exactly..the unfortunate astronauts were dying 😢. What a terrible death.

[@MrBaraniecki]

@GhosstofShadows thank you!

[@adamdickinson2894]

Where they first went wrong was pronouncing it 'aluminum' rather than the proper way. After that dropping of standards it was only a matter of time before a disaster like this occured

[@jenster29]

😂😂😂😂😂😂 Ah I needed that laugh.

[@CDigitalArt]

Alumium (1807) --> Aluminum --> Aluminium (1812) I think Alumium was the better choice overall

[@RD-ij2sz]

Sending shuttle s and spacecraft s with humans in them serves very little purpose and involves great risks . With all due respect for the work and experiment s done by astronaut s I feel that with the constraints in the space crafts these experiments can't be elaborate and serve little purpose . Missions with out humans have done much more.

[@jessicasimplicioreis3824]

Alguém assistindo??🐞🦋🤗😎

[@debbiebradney131]

Houston, we have a problem again.....It's your fault !.

[@davidcockburn370]

Did NASA Consider Titanium When building the Space Shuttles When Compared to other Materials Like Aluminium ?? Just a Thought Titanium takes The Heat !! And Still as Strong or Stronger than Steel !!

[@nobodyknows3180]

Weight considerations. The density of titanium and aluminum are 4.54 g/cc and 2.70 g/cc respectively. As you can see, the aluminum is almost half the weight per unit of volumn as the titanium. As for titanium, it has a melting point of 1600C which is 2912F, so it would withstand pretty much most of the temperatures encountered in re-entry.

[@GalacticGD]

Uhh how did they know what happened

[@junnrhillgailanan3429]

Reaserch innit

[@GalacticGD]

@@junnrhillgailanan3429 ah, make sense

[@matt87635]

Any way possible that they could have come in tail first until they broke through.

[@TM-oz2kt]

not really, the shuttle has a blunt nose purposely so it 'smashes'' its way through the atmosphere and spreads the plasma wave around the shuttle instead of into it. Coming in backwards would not achieve this.

[@hmdwgf]

Apparently each one of those carbon-carbon panels cost $800,000 each.

[@matt87635]

180 degrees tail up nose down flying backwards. Sulu could have down it.

[@glaza228]

I am Russian and I congratulate you on this event

[@jessicasimplicioreis3824]

Alguém assistindo??🦋😎🎱🤗

[@xScremii]

why didn't they cover the entire shuttle with reinforced carbon carbon

[@robadams8057]

Sammy Aff - Probably too expensive and/or heavy to cover the entire orbited with RCC.

[@hmdwgf]

Each one of those panels cost $800,000 a piece.

[@jessicasimplicioreis3824]

Mt bom...🌸🌸🌸💚

[@hoghogwild]

@TheAkpatriot That would be degrees (F).

[@dominicditommaso4487]

Everything cost money...

[@UjjwalKumar_234]

The shuttle when it is orbiting the earth has to have a specific velocity given by sqrt (H*g). which if you will calculate will turn out to be huge. So in short it speed of reentry is not a matter of choice.

[@jessicasimplicioreis3824]

[@wheelmanstan]

Ma'am, a giant piece of foam hit at high speed and I'd like permission to take a closer look w/powerful telescopes to assess damage. NOPE. Don't worry about it. Dear crew, foam hit, but it's usually no big deal. Linda Ham's conscience: Should I at least have them 15min space walk to the wing after ignoring the wing strike for 14 days ? Nah. It's just 7 lives.

[@sluice]

Why is this video split into stupid sections? It doesn't seem to have a sensible end point.

[@UltimateBMWfan]

Why aren't the panels all white? Wouldn't that help in reflecting some of that heat absorbed by the tiles?

[@UltimateBMWfan]

***** Gotcha, thanks ;)

[@robadams8057]

UltimateBMWfan: More important than the color is the material the tiles are made of. The black tiles are made of a material that withstands more heat than the white tiles.

[@CptMikeTango1]

+Rob Adams i thought they were just painted on

[@robadams8057]

No, the tiles that covered most of the orbiters were made of a material that was very specially designed to withstand the extreme heat of re-entry, and still be able to do it again dozens of times.

[@zillsburyy1]

with all that money that NASA has they should have lined the whole thing with those reinforced carbon panels that were on the wings

[@hmdwgf]

Each one of those carbon-carbon panels cost $800,000 a piece. The ceramics did their job.
