00:12
As a kid, I was fascinated with all things air and space.
0
12613
4438
Kao dijete fasciniralo me sve vezano uz zrak i svemir.
00:17
I would watch Nova on PBS.
1
17051
2541
Gledao sam emisiju Nova na PBS-u.
00:19
Our school would show Bill Nye the Science Guy.
2
19592
2953
Moja škola prikazivala je emisiju Bill Nye Znanstvenik.
00:22
When I was in elementary school, my next door neighbor,
3
22545
4125
Kad sam bio u osnovnoj školi, moj prvi susjed
00:26
he gave me a book for my birthday.
4
26670
1850
poklonio mi je knjigu za rođendan.
00:28
It was an astronomy book,
5
28520
1169
Bila je to knjiga o astronomiji
00:29
and I poured over that thing for hours on end,
6
29689
2952
i satima bih je pažljivo proučavao.
00:32
and it was a combination of all these things
7
32641
2600
Bila je to kombinacija svih ovih stvari
00:35
that inspired me to pursue space exploration
8
35241
3668
koje su me nadahnule da krenem u istraživanje svemira,
00:38
as my own personal dream, and part of that dream was,
9
38909
4468
što je bio moj san. Kao dio tog sna
00:43
I always wanted to just fly around the solar system
10
43377
2609
uvijek sam želio letjeti po Sunčevom sustavu
00:45
and visit different planets and visit moons and spacecraft.
11
45986
3397
i posjetiti različite planete, mjesece i svemirske letjelice.
00:49
Well, a number of years later, I graduated from UCLA
12
49383
4694
Godinama kasnije diplomirao sam na UCLA-u
00:54
and I found myself at NASA,
13
54077
2182
i našao se u NASA-i,
00:56
working for the jet propulsion laboratory,
14
56259
2104
radeći u laboratoriju za mlazni pogon,
00:58
and there our team was challenged
15
58363
2695
gdje je moj tim bio zadužen
01:01
to create a 3D visualization of the solar system,
16
61058
4389
za stvaranje 3D prikaza Sunčevog sustava.
01:05
and today I want to show you what we've done so far.
17
65447
3874
Danas vam želim pokazati što smo do sad napravili.
01:09
Now, the kicker is, everything I'm about to do here
18
69321
3386
Najbolje od svega jest da sve što ću ovdje učiniti
01:12
you can do at home, because we built this
19
72707
3806
možete napraviti i doma, zato što smo ovo izradili
01:16
for the public for you guys to use.
20
76513
2810
za javnost, kako biste vi to mogli koristiti.
01:19
So what you're looking at right now is the Earth.
21
79323
1921
Ovo što upravo gledate jest Zemlja.
01:21
You can see the United States and California
22
81244
1971
Možete vidjeti SAD, Kaliforniju,
01:23
and San Diego, and you can use the mouse
23
83215
2779
San Diego, a možete koristiti miš
01:25
or the keyboard to spin things around.
24
85994
2055
ili tipkovnicu kako biste sve rotirali.
01:28
Now, this isn't new. Anyone who's used Google Earth
25
88049
3439
To nije novina. Tko god je koristio Google Earth
01:31
has seen this before, but one thing we like to say
26
91488
3011
već je ovo vidio, ali u našoj grupi volimo reći
01:34
in our group is, we do the opposite of Google Earth.
27
94499
3813
da radimo suprotno od Google Eartha.
01:38
Google Earth goes from this view down to your backyard.
28
98312
4049
Google Earth ide od ovog pogleda dolje do vašeg dvorišta.
01:42
We go from this view out to the stars.
29
102361
3533
Mi idemo od ovog pogleda do zvijezda.
01:45
So the Earth is cool, but what we really want to show
30
105894
2927
Zemlja je cool, ali ono što vam zbilja želimo pokazati
01:48
are the spacecraft,
31
108821
1866
jesu letjelice
01:50
so I'm going to bring the interface back up,
32
110687
2745
pa ću opet vratiti sučelje.
01:53
and now you're looking at a number of satellites
33
113432
2722
Sada gledate nekoliko satelita
01:56
orbiting the Earth.
34
116154
937
koji kruže oko Zemlje.
01:57
These are a number of our science space Earth orbiters.
35
117091
3282
Ovo je nekoliko znanstvenih orbitera koji kruže oko Zemlje.
02:00
We haven't included military satellites and weather satellites
36
120373
2318
Nismo uključili vojne i meteorološke satelite,
02:02
and communication satellites and reconnaissance satellites.
37
122691
2013
kao ni komunikacijske i špijunske satelite.
02:04
If we did, it would be a complete mess,
38
124704
2499
Kad bismo to učinili, bio bi to potpuni kaos,
02:07
because there's a lot of stuff out there.
39
127203
2056
zato što gore ima stvarno puno toga.
02:09
And the cool thing is, we actually created 3D models
40
129259
3805
Stvorili smo 3D modele
02:13
for a number of these spacecraft, so if you want to visit
41
133064
3265
za niz tih letjelica pa ako želite posjetiti
02:16
any of these, all you need to do is double-click on them.
42
136329
3026
bilo koju od njih, samo trebate dva puta kliknuti na njih.
02:19
So I'm going to find the International Space Station,
43
139355
3236
Pronaći ću Međunarodnu svemirsku postaju (ISS),
02:22
double-click, and it will take us all the way down to the ISS.
44
142591
5007
dvostruki klik i odvest će nas do nje.
02:27
And now you're riding along with the ISS
45
147598
2609
A sada putujete skupa s ISS-om
02:30
where it is right now.
46
150207
3195
ondje gdje se upravo nalazi.
02:33
And the other cool thing is, not only can we
47
153402
1792
Cool je i to da možemo
02:35
move the camera around, we can also control time,
48
155194
3275
pomicati kameru uokolo, ali i kontrolirati vrijeme.
02:38
so I can slide this jog dial here
49
158469
2113
Tako mogu pomaknuti ovaj prikaz
02:40
to shuttle time forward, and now
50
160582
2295
unaprijed u vremenu i sad
02:42
we can see what a sunset on the ISS would look like,
51
162877
4433
možemo vidjeti kako izgleda zalazak sunca na ISS-u,
02:47
and they get one every 90 minutes. (Laughter)
52
167310
5453
a možete ga vidjeti i svakih 90 minuta. (Smijeh)
02:52
All right, so what about the rest of it?
53
172763
2583
Dobro, što je s ostatkom?
02:55
Well, I can click on this home button over here,
54
175346
2641
Pa, mogu kliknuti ovdje na tipku Home
02:57
and that will take us up to the inner solar system,
55
177987
2967
i to će nas odvesti do unutarnjeg dijela Sunčevog sustava,
03:00
and now we're looking at the rest of the solar system.
56
180954
2127
a sada gledamo ostatak Sunčevog sustava.
03:03
You can see, there's Saturn, there's Jupiter,
57
183081
2543
Ovdje možete vidjeti Saturn, ondje je Jupiter,
03:05
and while we're here, I want to point out something.
58
185624
3116
a kad smo već ovdje, želim nešto istaknuti.
03:08
It's actually pretty busy.
59
188740
2557
Ovdje je prilično prometno.
03:11
Here we have the Mars Science Laboratory
60
191297
2089
Ovdje je Mars Science Laboratory
03:13
on its way to Mars, just launched last weekend.
61
193386
2543
na putu do Marsa, tek lansiran prošli tjedan.
03:15
Here we have Juno on its cruise to Jupiter, there.
62
195929
3982
Ovo je Juno na svom putu do Jupitera, ondje.
03:19
We have Dawn orbiting Vesta,
63
199911
1962
Ovo je Dawn koji kruži oko Veste,
03:21
and we have over here New Horizons
64
201873
2010
a ovdje je New Horizons
03:23
on a straight shot to Pluto.
65
203883
2458
na direktnoj putanji prema Plutonu.
03:26
And I mention this because
66
206341
1955
To spominjem zato
03:28
there's this strange public perception that
67
208296
2805
što postoji čudno mišljenje u javnosti
03:31
NASA's dead, that the space shuttles stopped flying
68
211101
2793
da je NASA mrtva, da su shuttleovi prestali letjeti
03:33
and all of the sudden there's no more spacecraft out there.
69
213894
2584
te da odjednom više nema letjelica u svemiru.
03:36
Well, a lot of what NASA does is robotic exploration,
70
216478
4579
NASA obavlja mnogo istraživanja robotima
03:41
and we have a lot of spacecraft out there.
71
221057
2599
i ima mnogo letjelica u svemiru.
03:43
Granted, we're not sending humans up at the moment,
72
223656
2273
Istina, trenutno ne šaljemo ljude,
03:45
well at least with our own launch vehicles,
73
225929
2807
barem ne našim letjelicama,
03:48
but NASA is far from dead,
74
228736
2244
ali NASA nikako nije mrtva
03:50
and one of the reasons why we write a program like this
75
230980
3330
i jedan od razloga zašto pišemo programe poput ovog
03:54
is so that people realize that there's so many other things
76
234310
2487
jest da ljudi shvate da radimo toliko
03:56
that we're doing.
77
236797
1691
drugih stvari.
03:58
Anyway, while we're here, again,
78
238488
1722
Bilo kako bilo, dok smo ovdje, ponavljam,
04:00
if you want to visit anything,
79
240210
1930
ako želite bilo što posjetiti,
04:02
all you need to do is double-click.
80
242140
1917
potreban je tek dvostruki klik.
04:04
So I'm just going to double-click on Vesta,
81
244057
2570
Ja ću evo kliknuti na Vestu
04:06
and here we have Dawn orbiting Vesta,
82
246627
4094
i tu je Dawn koji kruži oko Veste,
04:10
and this is happening right now.
83
250721
2190
a to se sve događa upravo sada.
04:12
I'm going to double-click on Uranus, and we can see
84
252911
4207
Dvostruko ću kliknuti na Uran i vidimo ga
04:17
Uranus rotating on its side along with its moons.
85
257118
3308
kako kruži zajedno sa svojim mjesecima.
04:20
You can see how it's tilted at about 89 degrees.
86
260426
3792
Možete vidjeti kako je nakošen na oko 89 stupnjeva.
04:24
And just being able to visit different places
87
264218
3960
Možete posjetiti različita mjesta
04:28
and go through different times,
88
268178
1286
i proći kroz različita razdoblja,
04:29
we have data from 1950 to 2050.
89
269464
3095
imamo podatke od 1950. do 2050. godine.
04:32
Granted, we don't have everything in between,
90
272559
2217
Istina, nemamo sve između
04:34
because some of the data is hard to get.
91
274776
1766
zato što je do nekih podataka teško doći.
04:36
Just being able to visit places in different times,
92
276542
3915
Možete posjetiti mjesta u različitim razdobljima,
04:40
you can explore this for hours,
93
280457
3668
možete istraživati satima,
04:44
literally hours on end,
94
284125
1956
doslovno satima bez prestanka,
04:46
but I want to show you one thing in particular,
95
286081
2878
ali nešto vam posebno želim pokazati
04:48
so I'm going to open up the destination tab,
96
288959
2385
pa ću otvoriti prozor za odredište,
04:51
spacecraft outer planet missions, Voyager 1,
97
291344
3387
letjelice s misijom prema vanjskim planetima, Voyager 1,
04:54
and I'm going to bring up the Titan flyby.
98
294731
3000
i pokazat ću vam prelet kraj Titana.
04:57
So now we've gone back in time.
99
297731
2790
Sad smo otišli unatrag u vremenu.
05:00
We're now riding along with Voyager 1.
100
300521
2937
Sada putujemo zajedno s Voyagerom 1.
05:03
The date here is November 11, 1980.
101
303458
3397
Datum je 11. studenog 1980.
05:06
Now, there's a funny thing going on here.
102
306855
2329
Ovdje se događa nešto čudno.
05:09
It doesn't look like anything's going on.
103
309184
2193
Čini se kao da se ne događa ništa.
05:11
It looks like I've paused the program.
104
311377
2100
Izgleda kao da sam pauzirao program.
05:13
It's actually running at real rate right now,
105
313477
2026
Zapravo radi stvarnim tempom,
05:15
one second per second, and in fact,
106
315503
2000
sekundu po sekundi, i u biti,
05:17
Voyager 1 here is flying by Titan at
107
317503
3558
Voyager 1 ovdje leti kraj Titana
05:21
I think it's 38,000 miles per hour.
108
321061
4110
brzinom od 61.150 km/h, mislim.
05:25
It only looks like nothing's moving because, well,
109
325171
2703
Samo izgleda kao da se ne miče zato što, pa,
05:27
Saturn here is 700,000 miles away,
110
327874
2806
Saturn je odavdje udaljen oko 1.100.000 km,
05:30
and Titan here is 4,000 to 5,000 miles away.
111
330680
2842
a Titan je 6.500 do 8.000 km odavde.
05:33
It's just the vastness of space makes it look like nothing's happening.
112
333522
4085
Zbog beskrajnosti svemira čini se kao da se ništa ne događa.
05:37
But to make it more interesting,
113
337607
1878
No, kako bi bilo zanimljivije,
05:39
I'm going to speed up time, and we can watch
114
339485
2846
ubrzat ću protok vremena i možemo gledati
05:42
as Voyager 1 flies by Titan,
115
342331
2655
kako Voyager 1 leti kraj Titana,
05:44
which is a hazy moon of Saturn.
116
344986
2215
Saturnovog maglovitog mjeseca.
05:47
It actually has a very thick atmosphere.
117
347201
2304
Zapravo ima jako debelu atmosferu.
05:49
And I'm going to recenter the camera on Saturn, here.
118
349505
3261
Premjestit ću fokus kamere na Saturn.
05:52
I'm going to pull out, and I want to show you
119
352766
3889
Odmaknut ću se i želim vam pokazati
05:56
Voyager 1 as it flies by Saturn.
120
356655
3230
Voyager 1 kako leti kraj Saturna.
05:59
There's a point to be made here.
121
359885
2250
Ovdje vam želim skrenuti pažnju na nešto.
06:02
With a 3D visualization like this,
122
362135
2642
S 3D prikazom poput ovog,
06:04
we can not only just say Voyager 1 flew by Saturn.
123
364777
3781
možemo reći ne samo da je Voyager 1 proletio kraj Saturna,
06:08
There's a whole story to tell here.
124
368558
1622
već tu postoji cijela priča za ispričati.
06:10
And even better, because it's an interactive application,
125
370180
2856
I još bolje, kako je to interaktivna aplikacija,
06:13
you can tell the story for yourself.
126
373036
1980
možete je ispričati sa svog gledišta.
06:15
If you want to pause it, you can pause it.
127
375016
2205
Ako je želite pauzirati, možete je pauzirati.
06:17
If you want to keep going, if you want to change
128
377221
1487
Ako želite nastaviti, ako želite promijeniti
06:18
the camera angle, you can do that,
129
378708
2324
kut kamere, možete to učiniti
06:21
and because of that, I can show you
130
381032
2523
i zbog toga vam mogu pokazati
06:23
that Voyager 1 doesn't just fly by Saturn.
131
383555
2821
da Voyager 1 zapravo leti ispod Saturna,
06:26
It actually flies underneath Saturn.
132
386376
3979
ne samo pokraj njega.
06:30
Now, what happens is, as it flies underneath Saturn,
133
390355
3370
Kako leti ispod Saturna,
06:33
Saturn grabs it gravitationally and flings it up
134
393725
2911
Saturnova ga gravitacija zgrabi i baci ga gore
06:36
and out of the solar system,
135
396636
2290
i van iz Sunčevog sustava
06:38
so if I just keep letting this go,
136
398926
3038
pa ako nastavite ovo puštati,
06:41
you can see Voyager 1 fly up like that.
137
401964
4657
možete vidjeti Voyager 1 kako leti prema gore.
06:46
And, in fact, I'm going to go back to the solar system.
138
406621
2132
Zapravo ću se vratiti u Sunčev sustav,
06:48
I'm going to go back to today, now,
139
408753
2908
vratit ću se na današnji dan
06:51
and I want to show you where Voyager 1 is.
140
411661
3646
i želim vam pokazati gdje se Voyager 1 nalazi.
06:55
Right there, above, way above the solar system,
141
415307
4603
Točno tamo, iznad, daleko iznad Sunčevog sustava,
06:59
way beyond our solar system.
142
419910
2540
mnogo dalje od našeg Sunčevog sustava.

1628
Sada znate zašto, a za mene je
07:06
that's the point of this program.
145

to bit ovog programa.
07:08
You can manipulate it yourself.

Možete sami upravljati njime.
07:11

Sunčev sustav nadohvat ruke -- (Smijeh) --

i istražuju i vide kakva čuda postoje
07:33
and be inspired, as I was as a kid,

i budu nadahnuta, kao što sam i ja bio kao dijete,
07:36
to pursue STEM education

1558
da odaberu obrazovanje u znanosti, tehnologiji, inžinjerstvu ili matematici,
07:38
and to pursue a dream in space exploration.
