I leapt from the stratosphere. Here's how I did it | Alan Eustace

Prevoditelj: Sonja Žarić Recezent: Ivan Stamenković

So I grew up in Orlando, Florida.

Odrastao sam u Orlandu, Florida.

I was the son of an aerospace engineer.

Sin sam svemirskog inženjera.

I lived and breathed the Apollo program.

Živio sam i disao Apollo program.

We either saw the launches from our backyard

Ili smo vidjeli lansiranje iz dvorišta

or we saw it by driving in the hour over to the Cape.

ili bi se odvezli za sat do Capea i gledali lansiranje.

I was impressed by, obviously, space and everything about it,

Bio sam impresioniran, očito, svemirom i svime vezanim uz njega,

but I was most impressed by the engineering that went into it.

ali bio sam najviše impresioniran inženjeringom koji je korišten.

Behind me you see an amazing view,

Iza mene vidite veličanstven pogled,

a picture that was taken from the International Space Station,

slika uslikana na Međunarodnoj svemirskoj stanici

and it shows a portion of our planet

i prikazuje dio našeg planeta

that's rarely seen and rarely studied

koji se rijetko vidi i rijetko proučava

and almost never explored.

i skoro nikad ne istražuje.

That place is called the stratosphere.

To mjesto se naziva stratosfera.

If you start on the planet and you go up and up and up,

Ako krenete sa planeta i idete sve više i više i više,

it gets colder and colder and colder,

postaje sve hladnije i hladnije i hladnije,

until you reach the beginning of the stratosphere,

dok ne dostignete početak stratosfere,

and then an amazing thing happens.

i onda se dogodi nevjerojatna stvar.

It gets colder at a much slower rate, and then it starts warming up,

Hlađenje se usporava, i onda počinje zagrijavanje,

and then it gets warmer and warmer

i postaje sve toplije i toplije

until the point where you can almost survive without any protection,

do točke gdje je skoro nemoguće preživjeti bez ikakve zaštite,

about zero degrees,

približno nula stupnjeva,

and then you end up getting colder and colder,

i onda je opet sve hladnije i hladnije,

and that's the top of the stratosphere.

i to je vrh stratosfere.

It is one of the least accessible places on our planet.

To je jedno od najnedostupnijih mjesta na našoj planeti.

Most often, when it's visited,

Često, čak i kad se posjeti,

it's by astronauts who are blazing up at it

to su astronauti koji se goreći uspinju

at probably several times the speed of sound,

brzinom nekoliko puta većom od brzine zvuka,

and they get a few seconds on the way up,

i budu tamo samo par sekundi prema gore

and then they get this blazing ball of fire coming back in,

a onda opet na putu natrag postaju goruća vatrena lopta,

on the way back in.

na putu prema dolje.

But the question I asked is, is it possible to linger in the stratosphere?

Ali pitanje koje ja postavljam je, jel se moguće zadržati u stratosferi?

Is it possible to experience the stratosphere?

Jel moguće doživjeti stratosferu?

Is it possible to explore the stratosphere?

Jel moguće istražiti stratosferu?

I studied this using my favorite search engine

Proučavao sam to koristeći najdražu tražilicu

for quite a while, about a year,

u razdoblju od godinu dana,

and then I made a scary phone call.

i onda sam obavio strašan poziv.

It was a reference from a friend of mine to call Taber MacCallum

Prema preporuci prijatelja da nazovem Taber MacCallum

from Paragon Space Development Corporation,

iz korporacije za svemirski razvoj Paragon,

and I asked him the question:

i postavio sam mu pitanje:

is it possible to build

jel moguće sagraditi

a system to go into the stratosphere?

sustav koji će otići u stratosferu?

And he said it was.

I on je rekao da je moguće.

And after a period of about three years, we proceeded to do just that.

I u razdoblju od tri godine, smo nastavili raditi upravo to.

And on October 24 of last year,

24. listopada prošle godine

in this suit,

u ovom odijelu,

I started on the ground,

sam krenio sa tla,

I went up in a balloon to 135,890 feet --

i otišao u balonu na visinu od otprilike 42 kilometra --

but who's counting?

no, tko broji?

(Laughter)

(Smijeh)

Came back to Earth at speeds of up to 822 miles an hour.

Vratio se na zemlju pri brzinama do 1323 km/h

It was a four-minute and 27-second descent.

Silazak je trajao četiri minute i 27 sekundi.

And when I got to 10,000 feet, I opened a parachute and I landed.

No kad sam stigao do 3048 metara, otvorio sam padobran i sletio.

(Applause)

(Pljesak)

But this is really a science talk, and it's really an engineering talk,

No, ovo je ipak znanstveni govor, i inženjerski govor,

and what was amazing to me about that experience

i ono što me zadivilo kod ovog iskustva

is that Taber said, yes, I think we can build a stratospheric suit,

je to što je Taber rekao da, mislim da možemo izraditi stratosferno odijelo,

and more than that, come down tomorrow

i više od toga, dođi sutra ovdje

and let's talk to the team that formed the core of the group

i razgovarajmo sa timom koji čini jezgru grupe koja ga je

that actually built it.

zaista i izradila.

And they did something which I think is important,

Učinili su nešto što ja mislim da je važno,

which is they took the analogy of scuba diving.

a to je da su uzeli analogiju ronjenja.

So in scuba diving,

Pri ronjenju,

you have a self-contained system.

imate samoodrživi sustav.

You have everything that you could ever need.

Imate sve što bi vam ikad zatrebalo.

You have a scuba tank.

Imate ronilački spremnik.

You have a wetsuit.

Imate odijelo.

You have visibility.

Imate vidljivost.

And that scuba is exactly this system,

A to odijelo je upravo taj sustav,

and we're going to launch it into the stratosphere.

i mi ćemo ga lansirati u stratosferu.

Three years later, this is what we have.

Tri godine kasnije, ovo je ono što imamo.

We've got an amazing suit that was made by ILC Dover.

Imamo nevjerojatno odijelo koje je napravio ILC Dover.

ILC Dover was the company that made all of the Apollo suits

ILC Dover je tvrtka koja je napravila Apollo odijela

and all of the extravehicular activity suits.

i sva odijela za aktivnosti izvan vozila.

They had never sold a suit commercially,

Nikad nisu komercijalno prodavali odijela,

only to the government,

samo vladi,

but they sold one to me, which I am very grateful for.

ali su meni prodali jedno, na čemu sam veoma zahvalan.

Up here we have a parachute. This was all about safety.

Ovdje gore imamo padobran. Sve je u sigurnosti.

Everyone on the team knew

Svi u timu su znali

that I have a wife and two small children --

da imam ženu i dvoje male djece --

10 and 15 --

10 i 15 --

and I wanted to come back safely.

i da se želim sigurno vratiti kući.

So there's a main parachute and a reserve parachute,

Tako da imamo glavni padobran i rezervni padobran,

and if I do nothing,

i ako ništa ne napravim,

the reserve parachute is going to open because of an automatic opening device.

rezervni padobran će se otvoriti putem automatskog uređaja za otvaranje.

The suit itself can protect me from the cold.

Samo odijelo me može zaštititi od hladnoće.

This area in the front here has thermal protection.

Ovo područje ovdje ispred ima toplinsku zaštitu.

It will actually heat water that will wrap around my body.

Zapravo grije vodu koja uokviruje moje tijelo.

It has two redundant oxygen tanks.

Ima dva rezervna spremnika sa kisikom.

Even if I was to get a quarter-inch hole in this suit,

Kad bi se pojavila rupa od 6 mm u ovom odijelu,

which is extremely unlikely,

što je krajnje nevjerojatno,

this system would still protect me from the low pressure of space.

ovaj sustav će me i dalje zaštiti od niskog tlaka svemira.

The main advantage of this system is weight and complexity.

Glavna prednost ovog sustava je težina i složenost.

So the system weighs about 500 pounds,

Sustav teži oko 272 kg,

and if you compare it to the other attempt recently to go up in the stratosphere,

i ako usporedite sa ostalim nedavnim pokušajima odlaska u stratosferu,

they used a capsule.

oni su koristili kapsule.

And to do a capsule, there's an amazing amount of complexity that goes into it,

A sa kapsulama postoji nevjerojatna količina složenosti,

and it weighed about 3,000 pounds,

i teži 1360 kg,

and to raise 3,000 pounds to an altitude of 135,000 feet,

a da bi se 1360 kg podiglo na visinu od 42 km,

which was my target altitude,

što je moja ciljana visina,

it would have taken a balloon that was 45 to 50 million cubic feet.

bio bi potreban balon od 1.27 do 1.41 milijuna kubnih metara.

Because I only weighed 500 pounds in this system,

Ja težim samo 226.79 kg u ovom sustavu,

we could do it with a balloon that was five times smaller than that,

pa je moguće koristiti balon koji je pet puta manji od toga,

and that allowed us to use a launch system that was dramatically simpler

i dopušta nam da lansiramo sustav koji je značajno jednostavniji

than what needs to be done for a much larger balloon.

nego kod znatno većeg balona.

So with that, I want to take you to Roswell, New Mexico, on October 24.

Zatim, idemo do Roswella, New Mexico, 24. listopad.

We had an amazing team that got up in the middle of the night.

Imali smo nevjerojatan tim koji se ustao usred noći.

And here's the suit.

A evo i odijela.

Again, this is using the front loader that you'll see in a second,

Koristeći prednji utovarivač, koji ćete vidjeti za sekundu,

and I want to play you a video of the actual launch.

i želim vam i pokazati video stvarnog lansiranja.

Roswell's a great place to launch balloons,

Roswell je odlično mjesto za lansiranje balona,

but it's a fantastic place to land under a parachute,

i fantastično mjesto za slijetanje padobranom,

especially when you're going to land 70 miles away from the place you started.

posebno kad slijećete s udaljenosti od 113 km od starta.

That's a helium truck in the background.

Ovo je kamion s helijem u pozadini

It's darkness.

Tama je.

I've already spent about an hour and a half pre-breathing.

Već sam proveo oko sat i pol dišući.

And then here you see the suit going on.

A ovdje vidite odijevanje odijela.

It takes about an hour to get the suit on.

Potrebno je sat vremena za stavljanje odijela.

Astronauts get this really nice air-conditioned van

Astronauti dobiju stvarno ugodan klimatiziran kamion

to go to the launch pad, but I got a front loader.

da ih odveze do lansirne platforme, ali ja sam dobio utovarivač.

(Laughter)

(Smijeh)

You can see the top. You can see the balloon up there.

Vidi se vrh ovdje. Vidi se balon gore.

That's where the helium is.

Tamo je helij.

This is Dave clearing the airspace with the FAA for 15 miles.

Ovo Dave raščišava zračni prostor sa FAA-om na 24 km.

And there we go.

I krećemo.

(Laughter)

(Smijeh)

That's me waving with my left hand.

Ovo ja mašem lijevom rukom.

The reason I'm waving with my left hand

Razlog zašto mašem sa lijevom rukom

is because on the right hand is the emergency cutaway.

je zato što mi je na desnoj prekidač za hitne slučajeve.

(Laughter)

(Smijeh)

My team forbade me from using my right hand.

Tim mi je zabranio da koristim desnu ruku.

So the trip up is beautiful. It's kind of like Google Earth in reverse.

Put prema gore je predivan. Nešto kao Google Earth unazad.

(Laughter)

(Smijeh)

It took two hours and seven minutes to go up,

Trebalo mi je dva sata i sedam minuta za uspon,

and it was the most peaceful two hours and seven minutes.

i to je bilo najmirnijih dva sata i sedam minuta.

I was mostly trying to relax.

Većinom sam se trudio opustiti.

My heart rate was very low

Puls mi je bio vrlo nizak

and I was trying not to use very much oxygen.

i trudio sam se ne koristiti previše kisika.

You can see how the fields in the background

Možete vidjeti da su polja u pozadini

are relatively big at this point,

relativno velika u ovom trenutku,

and you can see me going up and up.

i možete me vidjeti kako idem sve više i više.

It's interesting here, because if you look,

Ovo je zanimljivo, jer ako pogledate,

I'm right over the airport, and I'm probably at 50,000 feet,

točno sam iznad zračne luke, i vjerojatno sam 15 km visoko,

but immediately I'm about to go into a stratospheric wind

no za trenutak će nastupiti stratosferni vjetar

of over 120 miles an hour.

od preko 193 km/h.

This is my flight director telling me that I had just gone higher

Ovo mi direktor leta govori da sam upravo otišao višlje

than anybody else had ever gone in a balloon,

nego itko ikad u balonu,

and I was about 4,000 feet from release.

i bio sam 1.2 km od puštanja.

This is what it looks like.

Ovako to izgleda.

You can see the darkness of space, the curvature of the Earth,

Možete vidjeti tminu svemira, zaobljenost Zemlje,

the fragile planet below.

krhki planet ispod.

I'm practicing my emergency procedures mentally right now.

Upravo mentalno vježbam procedure za hitne slučajeve

If anything goes wrong, I want to be ready.

Ako nešto pođe po krivu želim biti spreman.

And the main thing that I want to do here

A glavna stvar koju ovdje želim napraviti

is to have a release and fall and stay completely stable.

je pustiti i padati i ostati potpuno stabilan.

(Video) Ground control. Everyone ready?

(Video) Svi spremni?

Five. Four. Three. Two. One.

Pet. Četiri. Tri. Dva. Jedan.

Alan Eustace: There's the balloon going by, fully inflated at this point.

Alan Eustace: Evo balona koji prolazi potpuno napuhan u ovom trenutku.

And there you can see a drogue parachute, which I'll demonstrate in just a second,

A ovdje možete vidjeti konusni padobran, koji ću demonstrirati za trenutak,

because that's really important.

zato što je to zaista bitno.

There's the balloon going by a second time.

Evo balona drugi puta.

Right now, I'm about at the speed of sound.

Upravo idem brzinom zvuka.

There's nothing for me to tell it's the speed of sound,

Po ničemu ne mogu znati da je brzina zvuka u pitanju,

and very soon I will actually be as fast as I ever get,

i ubrzo ću postići najveću brzinu,

822 miles an hour.

1322 km/h.

(Video) Ground control: We lost the data.

(Video) Izgubili smo podatke.

AE: So now I'm down low right now

AE: Upravo sam dolje

and you can basically see the parachute come out right there.

i možete vidjeti aktiviranje padobrana.

At this point, I'm very happy that there's a parachute out.

U ovom trenutku sam veoma sretan što je padobran vani.

I thought I was the only one happy,

Mislio sam da sam jedini sretan,

but it turns out mission control was really happy as well.

ali ispada da je i kontrola veoma sretna isto.

The really nice thing about this is the moment I opened --

Lijepa stvar je što sam u trenutku otvaranja padobrana --

I had a close of friend of mine, Blikkies, my parachute guy.

imao vrlo bliskog prijatelja, Blikkies, mog tipa za padobrane.

He flew in another airplane, and he actually jumped out

Letio je drugim avionom, i zaista iskočio van

and landed right next to me.

i sletio pored mene.

He was my wingman on the descent.

Bio mi je pomoćnik pri silasku.

This is my landing, but it's probably more properly called a crash.

Ovo je moje slijetanje ili bolje rečeno tresak.

(Laughter)

(Smijeh)

I hate to admit it, but this wasn't even close to my worst landing.

Mrzim što moram priznati, ali ovo nije ni približno moje najgore slijetanje.

(Laughter)

(Smijeh)

(Applause)

(Pljesak)

(Video) Man: How are you doing?

(Video) Kako si?

AE: Hi there!

AE: Hej tamo!

Yay.

Jej!

(Laughter)

(Smijeh)

So I want to tell you one thing

Želim vam reći još nešto

that you might not have seen in that video,

što možda niste vidjeli u ovom videu,

but one of the most critical parts of the entire thing was the release

ali najkritičniji dio cijelog poduhvata je bilo puštanje

and what happens right after you release.

i što se dogodi kad se pustite.

And what we tried to do was use something called a drogue parachute,

Mi smo pokušali koristi nešto što se zove konusni padobran,

and a drogue parachute was there to stabilize me.

a on je bio potreban da me stabilizira.

And I'll show you one of those right now.

Pokazat ću vam jedan od tih padobrana sad.

If any of you have ever gone tandem skydiving,

Ako ste ikad probali zajedničko skakanje padobranom,

you probably used one of these.

vjerojatno ste koristili jedan ovakav.

But the problem with one of these things

Ali problem sa njima je

is right when you release, you're in zero gravity.

da ste u trenutku puštanja u stanju nulte gravitacije.

So it's very easy for this to just turn right around you.

Tako da je vrlo lako da se omota oko vas.

And before you know it, you can be tangled up or spinning,

I prije nego što se snađete, možete se zapetljati i zavrtjeti,

or you can release this drogue late,

ili možete zakasniti sa otvaranjem ovog padobrana,

in which case what happens is you're going down at 800 miles an hour,

u tom slučaju idete dolje 1290 km/h,

and this thing is going to destroy itself

i ovo će se uništiti

and not be very useful.

i neće više biti korisno.

But the guys at United Parachute Technologies came up with this idea,

Ali su momci u Ujedinjenim padobranskim tehnologijama došli na ovu ideju,

and it was a roll that looks like that,

a to je ovakav svitak,

but watch what happens when I pull it out.

pogledajte što se događa kad ga izvadim.

It's forming a pipe.

Tvori cijev.

This pipe is so solid

Ova cijev je toliko čvrsta

that you can take this drogue parachute and wrap it around,

da možete uzeti padobran i omotati ga okolo,

and there's no way it will ever tangle with you.

i nema šanse da ćete se zapetljati.

And that prevented a very serious potential problem.

A to je spriječilo veoma ozbiljan potencijalni problem.

So nothing is possible without an amazing team of people.

Ništa nije moguće bez nevjerojatnog tima ljudi.

The core of this was about 20 people

Jezgru ovog poduhvata je činilo oko 20 ljudi

that worked on this for the three years,

koji su radili na ovome tri godine,

and they were incredible.

i bili su veličanstveni.

People asked me what the best part of this whole thing was,

Ljudi me pitaju koji je bio najbolji dio cijele ove stvari,

and it was a chance to work with the best experts

to je bila prilika za rad sa najboljim stručnjacima

in meteorology and ballooning and parachute technology

u meteorologiji i balonima i tehnologiji padobrana

and environmental systems and high altitude medicine.

i sustavima okoline i medicini na velikim visinama.

It was fantastic. It's an engineer's dream to work with that group of people.

Bilo je fantastično. Inženjerov san je da radi sa takvom grupom ljudi.

And I also at the same time wanted to thank my friends at Google,

Želio bih zahvaliti i prijateljima u Googleu,

both for supporting me during this effort

za potporu tijekom ovog poduhvata

and also covering for me in the times that I was away.

i što su me pokrivali dok me nije bilo.

But there's one other group I wanted to thank, and that's my family.

Postoji još jedna grupa ljudi kojoj želim zahvaliti, to je moja obitelj.

Yay.

Jej.

(Applause)

(Pljesak)

I would constantly give them speeches about the safety of technology,

Konstantno sam im držao govore o sigurnosti tehnologije,

and they weren't hearing any of it.

a oni ne bi čuli ništa.

It was super hard on them,

Bilo im je jako teško,

and the only reason that my wife put up with it

i jedini razlog zašto mi je žena trpila sve ovo

was because I came back incredibly happy after each of the 250 tests,

je što bih se vratio nevjerojatno sretan nakon svakog od 250 testova,

and she didn't want to take that away from me.

nije mi htjela to oduzeti.

So I want to close with a story.

Želim završiti sa pričom.

My daughter Katelyn, my 15-year-old, she and I were in the car,

Moja kćer Katelyn, 15 godina, ona i ja smo bili u autu,

and we were driving down the road, and she was sitting there,

vozili smo niz cestu, i ona je sjedila tamo,

and she had this idea, and she goes, "Dad, I've got this idea."

i dobila ideju, pa je rekla, "Tata, imam ideju."

And so I listened to her idea and I said, "Katelyn, that's impossible."

Poslušao sam njenu ideju i rekao: "Katelyn, to je nemoguće."

And she looks at me

A ona me pogleda

and she goes, "Dad, after what you just did,

i kaže, "Tata, nakon ovog što si upravo napravio,

how can you call anything impossible?"

kako možeš išta nazvati nemogućim?"

And I laughed, and I said, "OK, it's not impossible,

Nasmijao sam se, i rekao, "OK, nije nemoguće,

it's just very, very hard."

nego vrlo, vrlo teško."

And then I paused for a second, and I said, "Katelyn,

Onda sam pauzirao na trenutak, i rekao, "Katelyn,

it may not be impossible, it may not even be very, very hard,

ne mora biti nemoguće, čak ni vrlo, vrlo teško,

it's just that I don't know how to do it."

nego samo ja ne znam kako to izvesti."

Thank you.

Hvala vam.

(Applause)

(Pljesak)
