00:12
I was 17 when I chose my career.
0
12810

Bilo mi je 17 godina kad sam se odlučila za buduću karijeru.
00:17
I was standing outside
1
17587
2389
Stajala sam vani
00:20
on a hot summer night in Florida
2
20000
2277
tijekom vruće ljetne noći na Floridi,
00:23
and just a few miles from the ocean.
3
23238
2327
samo nekoliko kilometara od oceana.
00:26
I was waiting for a miracle to happen.
4
26728
3397
Čekala sam da se čudo dogodi.
00:31
That summer, I was privileged to work as an intern
5
31540
3822
To ljeto imala sam povlasticu raditi kao pripravnik
00:35
at NASA's Kennedy Space Center,
6
35386
1883
u NASA-inom Svemirskom centru Kennedy,
00:37
and the miracle I was waiting for
7
37919
2261
a čudo koje sam čekala
00:40
was the launch of the Columbia Space Shuttle
8
40204
3521
bilo je lansiranje svemirske letjelice Columbia,
00:43
carrying the Chandra X-Ray Observatory,
9
43749
3153
koja je nosila Chandra opservatorij rengenskih zraka,
00:47
a telescope that would allow scientists to peer into the edge of black holes.
10
47486
6332
teleskop koji bi omogućio znanstvenicima da zavire u granice crnih rupa.
00:54
The entire sky filled with light.
11
54712
3005
Svo nebo ispunilo se svjetlošću.
00:58
And it was as if it was daytime in the middle of the night.
12
58998
3272
Bilo je poput dana usred noći.
01:03
Soon, we could feel the rumble of the engines vibrating in our chests.
13
63149
3845
Uskoro smo mogli osjetiti tutnjavu motora kako vibriraju u našim prsima.
01:08
And it wasn't a miracle;
14
68003
1581
I to nije bilo čudo,
01:10
it was the combined effort of a team of thousands of people
15
70316
4017
to je bio udruženi trud tima od tisuću ljudi
01:14
who worked together
16
74357
1291
koji su radili zajedno
01:15
to make was seemed impossible a reality.
17
75672
3284
kako bi učinili nemoguće stvarnim.
01:19
And I wanted to join that team.
18
79991
3729
Ja sam se htjela pridružiti tom timu.
01:24
So I decided to apply to a university where I could study aerospace engineering.
19
84872
4295
Stoga sam se prijavila na sveučilište gdje bih mogla studirati svemirski inženjering.
01:29
And the following year,
20
89644
1340
Sljedeće godine
01:31
I started at MIT in my engineering training
21
91008
2564
započela sam na MIT-u svoju obuku u inženjerstvu
01:33
and joined a student project building space robots.
22
93596
2742
i pridružila se studentskom projektu izgradnje svemirskih robota.
01:37
And everything was going as I planned,
23
97146
1879
Sve je išlo kao što sam i planirala,
01:39
except I was confused about something important.
24
99841
4638
jedino što sam bila zbunjena oko nečeg važnog.
01:45
Now, my confusion arose in my summer breaks.
25
105768
3087
Dakle, moja zbunjenost se pojavila tijekom mojih ljetnih praznika.
01:49
I traveled to a school in Kenya,
26
109474
2768
Putovala sam u školu u Keniji,
01:52
and there I volunteered with girls ages five to 17,
27
112915
4644
gdje sam volontirala radeći s djevojčicama dobi od 5 do 17 godina,
01:57
giving them lessons in English and math and science.
28
117583
4685
davala im instrukcije iz engleskog, matematike i prirode.
02:03
And they taught me songs in Swahili.
29
123143
2758
One su me učile pjesmama na svahiliju.
02:07
And mostly, I just spent time getting to know the girls,
30
127290
3554
Uglavnom sam vrijeme provodila upoznavajući se s djevojčicama,
02:10
enjoying their presence.
31
130868
1257
uživajući u njihovom društvu.
02:12
And I saw that these girls and the leaders in their community,
32
132754
4094
Vidjela sam da su te cure i vođe u njihovoj zajednici
02:16
they were overcoming important barriers
33
136872
2906
nadilazili vrlo važne prepreke
02:19
to allow these girls to have the best possible chances in life.
34
139802
3837
kako bi omogućili ovim djevojčicama da imaju najbolje šanse u životu.
02:24
And I wanted to join that team.
35
144556
3811
Htjela sam se pridružiti tom timu.
02:28
I wanted to be part of a team that would help break down barriers
36
148931
3057
Htjela sam biti dijelom tima koji će pomoći razbiti te prepreke
02:32
and improve the lives of girls around the world.
37
152012
2569
i poboljšati živote djevojčica diljem svijeta.
02:34
But I was worried that studying aerospace engineering
38
154605
3068
No, bojala sam se da studiranje svemirskog inženjeringa
02:37
wasn't the most useful.
39
157697
1481
nije baš najkorisnije.
02:39
I was worried this team in Kenya couldn't use the technology
40
159202
3160
Bojala sam se da ovaj tim u Keniji ne može koristiti tehnologiju
02:42
I was learning about space.
41
162386
1601
o kojoj sam ja učila o svemiru.
02:45
But thankfully, I still learned that I was wrong.
42
165305
3144
Srećom, saznala sam da sam u krivu.
02:49
I came back and interned at NASA again,
43
169457
2359
Vratila sam se i opet radila kao pripravnik u NASA-i
02:51
and this time,
44
171840
1158
i ovaj put
02:53
a mentor taught me
45
173022
1825
mentor me naučio
02:54
that countries like Kenya had been using space technology for decades
46
174871
6175
da se zemlje poput Kenije koriste svemirskom tehnologijom već desetljećima
03:01
to improve the lives in their own countries.
47
181070
2561
kako bi poboljšale život u svojim državama.
03:03
And then I knew that I could have a career in space
48
183655
3530
Tada sam znala da bih mogla imati karijeru u svemiru
03:07
and in development.
49
187209
1574
i u razvoju.
03:09
This idea is not new.
50
189859
1358
Ova ideja nije nova.
03:11
In fact, in 1967, the nations of the world came together
51
191825
4200
Naime, 1967. udružile su se nacije svijeta
03:16
to write the Outer Space Treaty.
52
196049
2743
kako bi potpisale Ugovor o svemiru.
03:19
This treaty made a bold statement,
53
199607
2662
Ovaj Ugovor dao je odvažnu izjavu
03:22
saying, "The exploration and use of outer space
54
202293
4062
govoreći: "istraživanje i korištenje svemira
03:26
should be carried on for the benefit of all peoples,
55
206379
3576
trebalo bi se odvijati u korist svih ljudi,
03:30
irrespective of their level of economic or scientific development."
56
210573
4894
bez obzira na njihovu razinu ekonomskog i znanstvenog razvoja".
03:37
We have not truly lived up to this ideal,
57
217089
2357
Nismo uistinu održali ovaj ideal,
03:39
although people have worked for decades to make this a reality.
58
219470
3219
iako su ljudi radili desetljećima kako bi to učinili stvarnim.
03:43
Forces such as colonialism and racism
59
223826
3506
Sile poput kolonijalizma, rasizma
03:47
and gender inequality
60
227880
1737
i nejednakosti spolova
03:50
have actually excluded many people from the benefits of space
61
230260
3525
zapravo su isključile mnoge ljude od pogodnosti svemira
03:54
and caused us to believe that space is for the few
62
234751
3541
i uvjerile nas da je svemir za pojedince
03:58
or the rich or elite.
63
238316
2226
ili za bogataše ili elitu.
04:01
But we cannot afford this attitude,
64
241731
2454
No, ne možemo si priuštiti ovaj stav,
04:04
because the world is engaged in a vital mission
65
244209
3131
jer je svijet uključen u ključnu misiju
04:07
to improve life for everyone.
66
247364
2004
poboljšanja života za sve.
04:10
Our road map for this mission comes from the 17 Sustainable Development Goals
67
250260
5789
Naš nacrt za ovu misiju proizlazi iz 17 Ciljeva o održivom razvoju
04:16
of the United Nations.
68
256073
1365
Ujedinjenih Naroda.
04:17
All the member states of the United Nations have agreed
69
257808
2699
Sve države članice UN-a su se složile
04:20
that these are priorities between now and 2030.
70
260531
3306
da su to prioriteti od sada do 2030.
04:24
These goals give us our key moments and opportunities of our time --
71
264526
5174
Ovi ciljevi daju nam ključne trenutke i prilike našeg vremena.
04:30
opportunities to end extreme poverty,
72
270323
2971
Prilike za okončavanje ekstremnog siromaštva;
04:33
to insure that everyone has access to food and clean water.
73
273318
4547
da osiguramo da svi imaju pristup hrani i čistoj vodi.
04:39
We must pursue these goals as a global community.
74
279720
3276
Moramo težiti ovim ciljevima kao globalna zajednica.
04:43
And technology from space supports sustainable development.
75
283861
4470
A svemirska tehnologija podupire održivi razvoj.
04:48
In fact, there are six space services
76
288891
3019
Zapravo, postoji šest svemirskih usluga
04:51
that can help us pursue the Sustainable Development Goals.
77
291934
3793
koje nam mogu pomoći u ostvarivanju Ciljeva o održivom razvoju.
04:56
Over the next few minutes, let's explore these six services,
78
296709
3253
Tijekom sljedećih nekoliko minuta, istražimo ovih šest usluga
04:59
and see examples of just a few of the goals they help support.
79
299986
3519
i pogledajmo primjere kako one podupiru bar neke od ciljeva.
05:03
You ready?
80
303529
1185
Jeste li spremni?
05:05
OK.
81
305104
1158
U redu.
05:06
Communication satellites provide access to phone and internet service
82
306286
4193
Komunikacijski sateliti daju pristup telefonu i internetskim uslugama
05:10
to almost any location on Earth.
83
310503
1738
gotovo bilo kojem mjestu na Zemlji.
05:12
This is particularly important during times of disaster recovery.
84
312622
3516
Ovo je od iznimne važnosti tijekom oporavka od prirodnih katastrofa.
05:16
When Typhoon Haiyan struck the Philippines,
85
316523
3518
Kada je tajfun Haiyan pogodio FIlipine,
05:20
the local communication networks needed to be repaired,
86
320065
2774
morale su se popraviti lokalne komunikacijske mreže
05:22
and teams brought in inflatable communication antennas
87
322863
3308
i timovi su donosili antenske nizove na napuhavanje
05:26
that could link to satellites.
88
326195
1990
koji su se mogli priključiti na satelite.
05:28
This was useful during the time of repair and recovery.
89
328209
2577
Ovo je bilo korisno tijekom vremena popravka i oporavka.
05:31
Positioning satellites tell us where we are
90
331453
3330
Sateliti za pozicioniranje govore nam gdje smo mi
05:34
by telling us where they are.
91
334807
1856
tako što nam kažu gdje su oni.
05:37
Scientists can use this technology to track endangered wildlife.
92
337835
4228
Znanstvenici koriste ovu tehnologiju u praćenju ugroženih životinja u divljini.
05:42
This turtle has been fitted with a system
93
342727
2510
Ova kornjača opremljena je sustavom
05:45
that allows it to receive location information from positioning satellites,
94
345261
4565
koji može primiti podatke o lokaciji od satelita za pozicioniranje,
05:49
and they send the location information to scientists
95
349850
2573
a oni šalju podatke o lokaciji znanstvenicima
05:52
via communication satellites.
96
352447
1574
putem komunikacijskih satelita.
Znanstvenici mogu koristiti ovo znanje kako bi donosili bolje smjernice
05:55
Scientists can use this knowledge to then make better policies
97
355112
3151
05:58
and help determine how to keep these animals alive.
98
358287
2410
i pomogli odrediti kako održati te životinje živima.
06:02
Earth observation satellites.
99
362460
2101
Sateliti za promatranje Zemlje.
06:04
They tell us what's going on in our environment.
100
364928
2594
Oni nam govore što se događa u našoj okolini.
06:07
Right now, there are about 150 satellites
101
367546
3498
Trenutačno postoji oko 150 satelita
06:11
operated by over 60 government agencies,
102
371068
2782
kojima upravlja preko 60 vladinih agencija,
06:13
and these are just those observing the Earth.
103
373874
2219
a to su samo one koje promatraju Zemlju.
06:16
And meanwhile, companies are adding to this list.
104
376117
2395
U međuvremenu, tvrtke nadopunjuju ovaj popis.
06:19
Most of the governments provide the data from the satellites for free online.
105
379157
3837
Većina vlada pruža podatke od satelita besplatno na internetu.
06:23
Some of these satellites provide images like this,
106
383018
3178
Neki od tih satelita pružaju slike poput ove,
06:26
that show what you would see from a camera.
107
386220
2412
koja vam pokazuje što biste vidjeli kroz kameru.
06:28
This is an image showing agricultural land in Kansas.
108
388656
2941
Ova slika pokazuje poljoprivredno zemljište u Kansasu.
06:32
However, the majority of the Earth observation satellites
109
392742
2885
Međutim, većina Zemljinih opservacijskih satelita
06:35
don't take pictures at all.
110
395651
2223
uopće ne slika.
06:37
They take measurements.
111
397898
1527
Oni uzimaju mjere,
06:39
And they combine these measurements with complex computer models
112
399449
3101
zatim kombiniraju te mjere s kompleksnim računalnim modelima
06:42
and make beautiful, global visualizations such as this one,
113
402574
3279
i stvaraju prekrasne, globalne vizualizacije poput ove,
06:45
showing the ocean currents
114
405877
1906
pokazujući oceanske struje
06:47
and the temperature of the ocean, globally.
115
407807
2024
i temperaturu oceana diljem svijeta.
06:51
Or we can look at the salt and smoke and dust in the atmosphere,
116
411275
5892
Ili možemo pogledati na sol, dim i prašinu u atmosferi;
06:59
or the rainfall and snowfall, globally,
117
419561
2675
na globalni pad oborina poput kiše i snijega;
07:05
as well as the annual cycle of vegetation on land and in the ocean.
118
425085
5001
na godišnji ciklus vegetacije na zemlji i u oceanu.
07:12
Now, scientists can take this information about the rainfall and the vegetation
119
432065
4362
Dakle, znanstvenici mogu iskoristiti ove podatke o padu oborina i vegetaciji
07:16
and use it to understand
120
436451
1390
u svrhu razumijevanja
07:17
what areas on Earth are in danger of a famine or a drought
121
437865
3765
koja područja na Zemlji su u opasnosti od gladi ili suše
07:21
and provide that information to aid organizations
122
441654
2642
i pružati te podatke kako bi pomogli organizacijama
07:24
so they can be prepared with food aid before the hunger becomes severe.
123
444320
3817
u pripremi zaliha hrane prije nego što glad postane ozbiljan problem.
07:28
In space, we have an orbiting laboratory on the International Space Station.
124
448900
4842
U svemiru imamo laboratorij u orbiti na Međunarodnoj svemirskoj postaji.
07:34
The vehicle and everything inside are in a form of free fall
125
454653
3028
Vozilo i unutrašnjost su u stanju slobodnog pada
07:37
around the Earth,
126
457705
1151
oko Zemlje
07:38
and they don't experience the effect of gravity.
127
458880
2330
te na njih nema utjecaja gravitacije.
07:42
And because of this, we call it "microgravity."
128
462219
2262
Zbog toga to nazivamo mikrogravitacijom.
07:45
When astronauts are in the microgravity environment,
129
465412
2463
Kad se astronauti nađu u mikrogravitacijskoj okolini,
07:47
their bodies react as if they're aging rapidly.
130
467899
3512
njihova tijela reagiraju kao da ubrzano stare.
07:51
Their bones and muscles weaken,
131
471888
2416
Kosti i mišići oslabe,
07:54
and their cardiovascular system and their immune system change.
132
474328
3554
njihov krvožilni i imunološki sustav se promijene.
Budući da znanstvenici proučavaju kako održati astronaute zdravima u svemiru,
07:59
As scientists study how to keep astronauts healthy in space,
133
479052
3248
08:02
we can take the exercises and techniques we use for astronauts
134
482324
3308
možemo preuzeti vježbe i tehnike koje astronauti koriste
08:05
and transfer them to people on Earth
135
485656
1952
i prenijeti ih ljudima na Zemlji
08:07
to improve our health here.
136
487632
1397
kako bismo ovdje poboljšali zdravlje.
08:09
Often, as we develop technology for astronauts and exploration
137
489465
3471
Često se dogodi da kad razvijamo tehnologiju za astronaute i istraživanje,
08:12
or for spacecraft,
138
492960
1270
ili za svemirske letjelice,
08:14
we can also transfer those inventions to improve life on Earth.
139
494254
3559
možemo prenijeti te izume za poboljšanje života na Zemlji.
08:17
Here's one of my favorites.
140
497837

Evo jedan od mojih omiljenih.
08:19
It's a water filtration system,
141
499195
1756
Ovo je sustav za filtriranje vode,
08:20
and a key component of it is based on the technology
142
500975
3023
njegova ključna sastavnica je temeljena na tehnologiji
08:24
to filter wastewater on the space station.
143
504022

08:26
It's now being used around the world.
144
506439
1781
Trenutno se koristi diljem svijeta.
08:28
Space is also an infinite source of inspiration,
145
508795
3418
Svemir je također beskonačan izvor inspiracije,
08:32
through education,
146
512237
1181
putem učenja,
08:33
through research and astronomy
147
513442
1634
putem istraživanja i astronomije
08:35
and that age-old experience of stargazing.
148
515100
3132
i onog prastarog iskustva zurenja u zvijezde.
08:38
Now, countries around the world are engaging in advancing
149
518818
3279
Sada se zemlje diljem svijeta uključuju u poboljšanje
08:42
their own development
150
522121
1176
vlastitog razvoja
08:43
by increasing their local knowledge of engineering and science and space.
151
523321
3847
tako što povećavaju vlastito znanje iz inženjerstva, znanosti i svemira.
08:47
Let's meet some of the world's newest satellite engineers.
152
527644
3867
Upoznajmo neke od najnovijih svjetskih satelitskih inženjera.
08:52
This is Elyka Abello, from Venezuela.
153

3058
Elyka se obučava za satelitskog inženjera
08:59
as part of her national satellite program in Venezuela.
155
539346
2816
kao dio njezinog državnog satelitskog programa u Venezueli.
09:02
She has designed a software tool
156
542750
1822
Ona je dizajnirala softverski alat
09:04
that allows her team to better design the power systems for engineering.
157
544596
3751
koji dopušta njezinom timu bolji dizajn pogonskog sustava za inženjerstvo.
09:10
This is Adel Castillo-Duran,
158
550036
2815
Ovo je Adel Castillo-Duran
09:12
from the Philippines.
159
552875
1150
s Filipina.
09:14
Adel is both a meteorologist and a satellite engineer,
160
554474
3007
Adel je i meteorologinja i satelitska inženjerka
09:17
and she uses data from satellites in her weather forecasting.
161
557505
3376
koja koristi podatke satelita u svojoj vremenskoj prognozi.
09:22
And finally, meet Hala.
162
562549
1573
I konačno, upoznajte Halu.
09:24
Hala is from the Sudan,
163
564708
1618
Hala je iz Sudana.
09:26
and as she was studying electrical engineering as an undergraduate
164
566350
3240
Dok je studirala elektrotehniku na preddiplomskom studiju
09:29
in Khartoum,
165
569614
1159
u Khartoumu,
09:30
she and several students decided to build their own satellite.
166
570797
3156
ona i nekoliko studenata odlučili su izraditi vlastiti satelit.
09:33
And later, Hala earned a scholarship to study satellite engineering
167
573977
4374
Poslije je Hala dobila stipendiju za studiranje satelitskog inženjerstva
09:38
at the graduate level.
168
578375
1316
na diplomskom studiju.
09:41
These stories that I've shared with you
169
581093
2274
Ove priče koje sam s vama podijelila
09:43
all illustrate that space truly is useful for sustainable development
170
583391
4113
sve pokazuju da je svemir uistinu koristan za održivi razvoj
09:47
for the benefit of all peoples.
171
587528
1774
i za dobrobit svih ljudi.
09:50
But we have more work to do,
172
590016
1743
No, imamo još posla,
09:52
because there are still barriers that exclude people from space
173
592487
3730
jer još postoje prepreke koje isključuju ljude od svemira
09:56
and limit the impact of this technology.
174
596241
2143
i ograničavaju učinak ove tehnologije.
09:59
For many people, Earth observation data is complex.
175
599402
3595
Za mnoge ljude, podaci o promatranju Zemlje su složeni.
10:03
And satellite communication services are too expensive.
176
603576
2712
Usluge komunikacijskih satelita previše su skupe.
10:06
And microgravity research just appears to be inaccessible.
177
606966
3475
Istraživanje mikrogravitacije se doima jednostavno nepristupačnim.
10:11
This is what motivates my work as a professor at MIT's Media Lab.
178
611611
4798
To je ono što me motivira kao profesora u MIT-evom Medijskom laboratoriju.
10:16
I've recently founded a new research group called Space Enabled.
179
616840
5155
Nedavno sam osnovala novu istraživačku grupu nazvanu "Svemir omogućen".
10:22
We are working to tear down these barriers that limit the benefits of space.
180
622829
4339
Radimo na razbijanju barijera koje ograničavaju pogodnosti svemira.
10:27
And we're also going to develop the future applications
181
627699
2648
Također ćemo razviti buduće primjene
10:30
that will continue to contribute to sustainable development.
182
630371
3280
koje će nastaviti doprinositi održivom razvoju.
10:34
We'll keep on this work
183
634533
1608
Radit ćemo na tome
10:36
until we can truly say that space is for the benefit of all peoples,
184
636165
4176
dok uistinu ne budemo mogli reći da je svemir za dobrobit svih ljudi
10:40
and we are all space enabled.
185
640834
3138
i da nam je svemir svima omogućen.
10:44
Thank you.
186
644815
1159
Hvala vam.
10:45
