As a kid, I was fascinated with all things air and space.
0

4438
Dok sam bio dete, fascinirao me je svemir.
00:17
I would watch Nova on PBS.
1
5051
2541
Gledao sam razne emisije te tematike na televiziji,
00:19
Our school would show Bill Nye the Science Guy.
2
7592
2953
a i u školi smo se sretali s njima.
00:22
When I was in elementary school, my next door neighbor,
3
10545
4125
Dok sam bio u osnovnoj školi, komšija mi je
00:26
he gave me a book for my birthday.
4
14670
1850
poklonio knjigu za rođendan.
00:28
It was an astronomy book,
5
16520
1169
To je bila knjiga o astronomiji
00:29
and I poured over that thing for hours on end,
6
17689
2952
i satima sam sedeo nad njome
00:32
and it was a combination of all these things
7
20641
2600
i kombinacija svega ovoga
00:35
that inspired me to pursue space exploration
8
23241
3668
inspirisala me je da se posvetim istraživanju svemira,
00:38
as my own personal dream, and part of that dream was,
9
26909
4468
što mi je bilo san, a deo tog sna
00:43
I always wanted to just fly around the solar system
10
31377
2609
uvek je bio da letim kroz Sunčev sistem
00:45
and visit different planets and visit moons and spacecraft.
11
33986
3397
i posećujem različite planete i mesece i svemirske letelice.
00:49
Well, a number of years later, I graduated from UCLA
12
37383
4694
Pa, godinama kasnije, diplomirao sam
na Kalifornijskom univerzitetu
na Kalifornijskom univerzitetu
00:54
and I found myself at NASA,
13
42077
2182
i zatekao se u NASI,
00:56
working for the jet propulsion laboratory,
14
44259
2104
gde sam radio u laboratoriji za mlazni pogon
00:58
and there our team was challenged
15
46363
2695
i naš tim se prihvatio izazova
01:01
to create a 3D visualization of the solar system,
16
49058
4389
da napravi 3D vizualizaciju Sunčevog sistema,
01:05
and today I want to show you what we've done so far.
17
53447
3874
a danas želim da vam pokažem
šta smo do sada napravili.
šta smo do sada napravili.
01:09
Now, the kicker is, everything I'm about to do here
18
57321
3386
E, sad, začkoljica je u tome da sve što ću vam pokazati
01:12
you can do at home, because we built this
19
60707
3806
možete izvesti kod kuće, jer smo to napravili
01:16
for the public for you guys to use.
20
64513
2810
za javnost, za vas.
01:19
So what you're looking at right now is the Earth.
21
67323
1921
Sada vidite planetu Zemlju.
01:21
You can see the United States and California
22
69244
1971
Vidite Sjedinjene Države i Kaliforniju
01:23
and San Diego, and you can use the mouse
23
71215
2779
i San Dijego i mišem
01:25
or the keyboard to spin things around.
24
73994
2055
ili tastaturom možete da se krećete.
01:28
Now, this isn't new. Anyone who's used Google Earth
25
76049
3439
Naravno da to nije novost. Ko god je koristio Google Earth
01:31
has seen this before, but one thing we like to say
26
79488
3011
ovo je već video, ali mi volimo da kažemo,
01:34
in our group is, we do the opposite of Google Earth.
27
82499
3813
međusobno, da radimo suprotno od Google Eartha.
01:38
Google Earth goes from this view down to your backyard.
28
86312
4049
Iz ovog pregleda Google Earth ide ka vašem dvorištu.
01:42
We go from this view out to the stars.
29
90361
3533
Mi idemo ka zvezdama.
01:45
So the Earth is cool, but what we really want to show
30
93894
2927
Zemlja jeste zanimljiva, ali mi želimo da pokažemo
01:48
are the spacecraft,
31
96821
1866
svemirske letelice,
01:50
so I'm going to bring the interface back up,
32
98687
2745
pa ću udaljiti prikaz
01:53
and now you're looking at a number of satellites
33
101432
2722
i sada gledate u brojne satelite
01:56
orbiting the Earth.
34
104154
937
u Zemljinoj orbiti.
01:57
These are a number of our science space Earth orbiters.
35
105091
3282
To su brojni Zemljini naučni orbiteri.
02:00
We haven't included military satellites and weather satellites
36
108373
2318
Nismo uključili vojne i meteorološke satelite,
02:02
and communication satellites and reconnaissance satellites.
37
110691
2013
niti komunikacijske i istraživačke satelite.
02:04
If we did, it would be a complete mess,
38
112704
2499
Da jesmo, videli bismo haos,
02:07
because there's a lot of stuff out there.
39
115203
2056
jer njih tamo gore ima mnogo.
02:09
And the cool thing is, we actually created 3D models
40
117259
3805
A zanimljivo je da smo, u stvari, napravili 3D modele
02:13
for a number of these spacecraft, so if you want to visit
41
121064
3265
mnogih od ovih svemirskih letelica,
pa ako želite da posetite
pa ako želite da posetite
02:16
any of these, all you need to do is double-click on them.
42
124329
3026
neku od njih, dovoljan je dvoklik na letelicu.
02:19
So I'm going to find the International Space Station,
43
127355
3236
Ja ću sada pronaći Međunarodnu svemirsku stanicu,
02:22
double-click, and it will take us all the way down to the ISS.
44
130591
5007
a dvoklik će nas dovesti do nje.
02:27
And now you're riding along with the ISS
45
135598
2609
Sada se krećemo sa njom,
02:30
where it is right now.
46
138207
3195
vidimo gde je sada.
02:33
And the other cool thing is, not only can we
47
141402
1792
Druga zanimljiva stvar je da ne samo da možemo
02:35
move the camera around, we can also control time,
48
143194
3275
da pomeramo kameru, već i da kontrolišemo vreme,
02:38
so I can slide this jog dial here
49
146469
2113
pa mogu da pomerim ovo dugme
02:40
to shuttle time forward, and now
50
148582
2295
da bih ubrzao vreme i sada
02:42
we can see what a sunset on the ISS would look like,
51
150877
4433
možemo videti kako sa stanice
izgleda zalazak sunca,
izgleda zalazak sunca,
02:47
and they get one every 90 minutes. (Laughter)
52
155310
5453
koji se vidi na svakih sat i po. (Smeh)
02:52
All right, so what about the rest of it?
53
160763
2583
Dobro, a šta je sa ostatkom?
02:55
Well, I can click on this home button over here,
54
163346
2641
Pa, ako kliknem na dugme Početna,
02:57
and that will take us up to the inner solar system,
55
165987
2967
to će nas uvesti u unutrašnji Sunčev sistem,
03:00
and now we're looking at the rest of the solar system.
56
168954
2127
a sada gledamo ostatak Sunčevog sistema.
03:03
You can see, there's Saturn, there's Jupiter,
57
171081
2543
Pogledajte, eno Saturna, eno Jupitera,
03:05
and while we're here, I want to point out something.
58
173624
3116
a kada smo već tu, hoću da vam
na nešto skrenem pažnju.
na nešto skrenem pažnju.
03:08
It's actually pretty busy.
59
176740
2557
Prilična je gužva.
03:11
Here we have the Mars Science Laboratory
60
179297
2089
Ovde vidimo Naučnu laboratoriju za Mars,
03:13
on its way to Mars, just launched last weekend.
61
181386
2543
koja putuje ka Marsu, lansirana je prošlog vikenda.
03:15
Here we have Juno on its cruise to Jupiter, there.
62
183929
3982
Ovde vidimo Junonu koja putuje ka Jupiteru.
03:19
We have Dawn orbiting Vesta,
63
187911
1962
Ovo je Zora koja orbitira oko Veste,
03:21
and we have over here New Horizons
64
189873
2010
a ovde Novi horizonti,
03:23
on a straight shot to Pluto.
65
191883
2458
satelit upućen ka Plutonu.
03:26
And I mention this because
66
194341
1955
Sve ovo pominjem
03:28
there's this strange public perception that
67
196296
2805
jer javno mnenje pogrešno veruje
03:31
NASA's dead, that the space shuttles stopped flying
68
199101
2793
da je NASA propala, da svemirski avioni više ne lete
03:33
and all of the sudden there's no more spacecraft out there.
69
201894
2584
i da u svemiru odjednom više nema svemirskih letelica.
03:36
Well, a lot of what NASA does is robotic exploration,
70
204478
4579
Pa, NASA se većinom bavi robotskim istraživanjima
03:41
and we have a lot of spacecraft out there.
71
209057
2599
i u svemiru ima dosta svemirskih letelica.
03:43
Granted, we're not sending humans up at the moment,
72
211656
2273
Istina je da se ljudi trenutno ne šalju u svemir,
03:45
well at least with our own launch vehicles,
73
213929
2807
bar ne našim lansirnim raketama,
03:48
but NASA is far from dead,
74
216736
2244
ali NASA nije ni blizu propasti,
03:50
and one of the reasons why we write a program like this
75
218980
3330
i jedan od razloga zbog kojih se ovakvi programi pišu
03:54
is so that people realize that there's so many other things
76
222310
2487
jeste da ljudi shvate da se mi bavimo
03:56
that we're doing.
77
224797
1691
i mnogim drugim stvarima.
03:58
Anyway, while we're here, again,
78
226488
1722
Bilo kako bilo, kad smo već tu, da ponovim,
04:00
if you want to visit anything,
79
228210
1930
ako želite bilo šta da posetite,
04:02
all you need to do is double-click.
80
230140
1917
možete to uraditi običnim dvoklikom.
04:04
So I'm just going to double-click on Vesta,
81
232057
2570
Ja ću to sada uraditi na Vesti,
04:06
and here we have Dawn orbiting Vesta,
82
234627
4094
ovde vidimo Zoru kako orbitira oko Veste,
04:10
and this is happening right now.
83
238721
2190
i to baš u ovom trenutku.
04:12
I'm going to double-click on Uranus, and we can see
84
240911
4207
Sada ću kliknuti dvoklikom na Uran, pa možemo videti
04:17
Uranus rotating on its side along with its moons.
85
245118
3308
kako se Uran okreće zajedno sa svojim mesecima.
04:20
You can see how it's tilted at about 89 degrees.
86
248426
3792
Vidite da je nagnut oko 89 stepeni.
04:24
And just being able to visit different places
87
252218
3960
A činjenica je da možete da posetite mesta
04:28
and go through different times,
88
256178
1286
i da proputujete kroz različita vremena,
04:29
we have data from 1950 to 2050.
89
257464
3095
jer imamo podatke od 1950. do 2050. godine.
04:32
Granted, we don't have everything in between,
90
260559
2217
Ipak, nemamo baš sve između,
04:34
because some of the data is hard to get.
91
262776
1766
jer je neke podatke teško dobiti.
04:36
Just being able to visit places in different times,
92
264542
3915
Jednostavno možete posetiti mesta
u različitim vremenima,
u različitim vremenima,
04:40
you can explore this for hours,
93
268457
3668
možete to istraživati satima,
04:44
literally hours on end,
94
272125
1956
bukvalno satima,
04:46
but I want to show you one thing in particular,
95
274081
2878
ali hoću da vam pokažem nešto naročito,
04:48
so I'm going to open up the destination tab,
96
276959
2385
pa ću otvoriti traku sa odredištima,
04:51
spacecraft outer planet missions, Voyager 1,
97
279344
3387
misije svemirskih letelica za spoljašnje planete, Vojadžer 1,
04:54
and I'm going to bring up the Titan flyby.
98
282731
3000
i pokrenuću preletača Titana.
04:57
So now we've gone back in time.
99
285731
2790
I sada smo se vratili kroz vreme.
05:00
We're now riding along with Voyager 1.
100
288521
2937
Sada putujemo sa Vojadžerom 1.
05:03
The date here is November 11, 1980.
101
291458
3397
Datum je 11. novembar 1980. godine.
05:06
Now, there's a funny thing going on here.
102
294855
2329
E, sad, tu se dešava nešto neobično.
05:09
It doesn't look like anything's going on.
103
297184
2193
A čini se kao da se ne dešava ništa.
05:11
It looks like I've paused the program.
104
299377
2100
Izgleda kao da sam pauzirao program.
05:13
It's actually running at real rate right now,
105
301477
2026
U stvari se pokreće u realnom vremenu,
05:15
one second per second, and in fact,
106
303503
2000
sekundu u sekundi i u stvari,
05:17
Voyager 1 here is flying by Titan at
107
305503
3558
ovde Vojadžer 1 leti naporedo sa Titanom
05:21
I think it's 38,000 miles per hour.
108
309061
4110
brzinom od, mislim, 61.142 km/h.
05:25
It only looks like nothing's moving because, well,
109
313171
2703
Samo se čini kao da se ništa ne kreće jer je
05:27
Saturn here is 700,000 miles away,
110
315874
2806
Saturn ovde udaljen 1.126.300 km,
05:30
and Titan here is 4,000 to 5,000 miles away.
111
318680
2842
a Titan je ovde udaljen 6500 - 8000 km.
05:33
It's just the vastness of space makes it look like nothing's happening.
112
321522
4085
Veličina svemira čini da izgleda kao da se ne dešava ništa.
05:37
But to make it more interesting,
113
325607
1878
Ali da bi sve bilo još zanimljivije,
05:39
I'm going to speed up time, and we can watch
114
327485
2846
ubrzaću vreme, pa možemo pogledati
05:42
as Voyager 1 flies by Titan,
115
330331
2655
kako Vojadžer 1 proleće pored Titana,
05:44
which is a hazy moon of Saturn.
116
332986
2215
a on je Saturnov lenji mesec.
05:47
It actually has a very thick atmosphere.
117
335201
2304
U stvari ima prilično gustu atmosferu.
05:49
And I'm going to recenter the camera on Saturn, here.
118
337505
3261
Sada ću pozicionirati kameru na Saturn, ovde.
05:52
I'm going to pull out, and I want to show you
119
340766
3889
Sada ću se izvući i hoću da vam pokažem
05:56
Voyager 1 as it flies by Saturn.
120
344655
3230
kako Vojadžer 1 proleće pored Saturna.
05:59
There's a point to be made here.
121
347885
2250
Ovde imam poentu priče.
06:02
With a 3D visualization like this,
122
350135
2642
Sa ovakvom 3D vizualizacijom,
06:04
we can not only just say Voyager 1 flew by Saturn.
123
352777
3781
ne možemo reći da je Vojadžer 1
samo proleteo pored Saturna.
samo proleteo pored Saturna.
06:08
There's a whole story to tell here.
124
356558
1622
Tu postoji cela priča.
06:10
And even better, because it's an interactive application,
125
358180
2856
I što je još bolje, pošto je u pitanju
interaktivna aplikacija,
interaktivna aplikacija,
06:13
you can tell the story for yourself.
126
361036
1980
možete priču ispričati sebi.
06:15
If you want to pause it, you can pause it.
127
363016
2205
Ako želite da je pauzirate, možete to uraditi.
06:17
If you want to keep going, if you want to change
128
365221
1487
Ako hoćete da nastavite ili da promenite
06:18
the camera angle, you can do that,
129
366708
2324
ugao kamere, možete to da uradite,
06:21
and because of that, I can show you
130
369032
2523
i zbog toga mogu da vam pokažem
06:23
that Voyager 1 doesn't just fly by Saturn.
131
371555
2821
da Vojadžer 1 nije samo proleteo pored Saturna.
06:26
It actually flies underneath Saturn.
132
374376
3979
U stvari je proleteo ispod Saturna.
06:30
Now, what happens is, as it flies underneath Saturn,
133
378355
3370
Sada, dešava se da, pošto leti ispod Saturna,
06:33
Saturn grabs it gravitationally and flings it up
134
381725
2911
Saturn ga zarobljava svojom gravitacijom i podiže
06:36
and out of the solar system,
135
384636
2290
i izbacuje iz Sunčevog sistema,
06:38
so if I just keep letting this go,
136
386926
3038
i ako ja ovo dozvolim,
06:41
you can see Voyager 1 fly up like that.
137
389964
4657
videćete Vojadžer kako leti baš tako.
06:46
And, in fact, I'm going to go back to the solar system.
138
394621
2132
U stvari, sada ću se vratiti u Sunčev sistem.
06:48
I'm going to go back to today, now,
139
396753
2908
I vratiću se u danas, u sada,
06:51
and I want to show you where Voyager 1 is.
140
399661
3646
da bih vam pokazao gde je Vojadžer 1.
06:55
Right there, above, way above the solar system,
141
403307
4603
Baš tamo, daleko, daleko iznad Sunčevog sistema,
06:59
way beyond our solar system.
142
407910
2540
daleko izvan našeg Sunčevog sistema.
07:02
And here's the thing. Now you know how it got there.
143
410450
2587
A stvar je u tome da vam je sada jasno otkud tamo.
07:05
Now you know why, and to me,
144
413037
1628
Sada znate zašto, a po mom mišljenju
07:06
that's the point of this program.
145
414665
1788
to i jeste suština ovog programa.
07:08
You can manipulate it yourself.
146
416453
3273
Njime možete upravljati sami.
07:11
You can fly around yourself and you can learn for yourself.
147
419726
3296
Možete „leteti“ okolo i sami učiti.
07:15
You know, the theme today is "The World In Your Grasp."
148
423022
3491
Znate, današnja tema je „Svet na dohvat ruke“.
07:18
Well, we're trying to give you
149
426513
1422
Zato pokušavamo da vam damo
07:19
the solar system in your grasp — (Laughter) —
150
427935
1597
Sunčev sistem na dohvat ruke -- (Smeh) --
07:21
and we hope once it's there,
151
429532
1549
a nadamo se da ćete, kada ga jednom dobijete,
07:23
you'll be able to learn for yourself
152
431081
2253
moći sami da otkrijete
07:25
what we've done out there, and what we're about to do.
153
433334
2194
šta smo napravili i šta ćemo tek napraviti.
07:27
And my personal dream is for kids to take this
154
435528
3499
Moja je lična želja da deca ovo prihvate
07:31
and explore and see the wonders out there
155
439027
2685
i istraže i vide sva čuda koja se nalaze tamo negde
07:33
and be inspired, as I was as a kid,
156
441712
3009
i da dobiju inspiraciju, kao i ja kada sam bio dete,
07:36
to pursue STEM education
157
444721
1558
da se obrazuju u oblasti nauke, tehnologije,
inženjeringa i matematike,
inženjeringa i matematike,
07:38
and to pursue a dream in space exploration.
158
446279
2750
i da se posvete istraživanju svemira.
07:41
Thank you. (Applause)
