Satelitske snimke revolucionarizirale su naše znanje o Zemlji, sa detaljnim slikama gotovo svakog kutka ulice lako dostupnog online. Ali Will Marshall iz Planet Laba kaže kako možemo raditi bolje i ići brže — postajući manji. Uvodi majušne satelite — ne veće od 10 puta 10 puta 30 centimetara — koji, kada ih se lansira u jatu, donose slike cijelog planeta u visokoj rezoluciji, ažurirane na dnevnoj bazi.

00:30
to realize that we're on

00:33
fragile and finite as it is,

krhkom i konačnom kakav jest,
00:35
and that we need
to take care of it.

I da se trebamo pobrinuti za nju.
00:37
But while this picture
is beautiful, it's static,
is beautiful, it's static,
8
25643
2981
Ali iako je ova slika
prekrasna, statična je
prekrasna, statična je
00:40
and the Earth is constantly changing.
9
28624
2553
a Zemlja se stalno mijenja.
00:43
It's changing on days' time
scales with human activity.

00:46
And the satellite imagery we

Satelitske snimke
koje imamo danas su stare.

00:49
Typically, years old.
12
37975

Tipično, godinama stare.
00:52
And that's important because
you can't fix what you can't see.

A to je bitno jer ne možete popraviti

00:56
What we'd ideally want is images

14
44735
4860
Što bismo idealno željeli su
slike cijelog planeta svaki dan
slike cijelog planeta svaki dan
01:01
So, what's standing in our way?
15
49595
2276
Dakle, što nam stoji na putu?
01:03
What's the problem?
16
51871
2011
Što je problem?
01:05
This is the problem:
17
53882
2026
To je problem:
01:07
Satellites are big, expensive
and they're slow.
and they're slow.
18
55908
4283
Sateliti su veliki, skupi i spori.
01:12
This one weighs three tons.
19
60191
2141
Ovaj je težak tri tone.
01:14
It's six meters tall, four meters wide.
20
62332
2765
Visok je šest metara, širok četiri.
01:17
It took up the entire fairing
of a rocket just to launch it.

Potreban je cijeli prtljažni prostor rakete
samo da ga se lansira.

01:20
One satellite, one rocket.
22
68330
1850
Jedan satelit, jedna raketa.
01:22
It cost 855 million dollars.
23
70180

Košta 855 milijuna dolara.
01:25
Satellites like these have
done an amazing job

24
73380
2234
Sateliti poput ovoga su
napravili zapanjujuć posao
napravili zapanjujuć posao
01:27
at helping us to understand our planet.
25
75614
3116
pomažući nam da shvatimo svoj planet.
01:30
But if we want to understand
it much more regularly,
it much more regularly,
26
78730
3626
Ali ako ga želimo
shvatiti puno redovitije,
shvatiti puno redovitije,
01:34
we need lots of satellites,
27
82356
2046
trebamo puno satelita,
01:36
and this model isn't scalable.
28
84402
1971
i ovaj model nije skalabilan.
01:38
So me and my friends,
we started Planet Labs
we started Planet Labs
29
86373
2103
Pa smo ja i moji prijatelji,
osnovali smo Planet Labs
osnovali smo Planet Labs
01:40
to make satellites ultra-compact
30
88476
2086
da napravimo satelite ultra kompaktnima
01:42
and small and highly capable.
31
90562
2287
i malima i jako sposobnima.
01:44
I'm going to show you what
our satellite looks like:
our satellite looks like:
32
92849
5011
Pokazat ću vam
kako naš satelit izgleda:
kako naš satelit izgleda:
01:52
This is our satellite.
33
100363
2537
Ovo je naš satelit.
01:54
This is not a scale model,
34
102900
1963
Ovo nije umanjeni model,
01:56
this is the real size.
35
104863
1508
ovo je prava veličina.
01:58
It's 10 by 10 by 30 centimeters,
36
106371
2386
To je 10x10x30 centimetara,
02:00
it weighs four kilograms,
37
108757
2289
teži četiri kilograma,
02:03
and we've stuffed the latest
and greatest electronics
and greatest electronics
38
111046
2537
i napunili smo najnoviju
i najbolju elektroniku

02:05
and sensor systems into
this little package
this little package
39
113583
2257
i sustave senzora
u ovaj mali paket
u ovaj mali paket
02:07
so that even though this is really small,
40
115840
2044
Tako da iako je zbilja malen,
02:09
this can take pictures 10 times the
resolution of the big satellite here,
resolution of the big satellite here,
41
117884
5093
ovaj može uzimati slike 10 puta
veće rezolucije od tog velikog satelita,

02:14
even though it weighs one
thousandth of the mass.

42
122977
4410
iako teži svega
tisućinu njegove mase.
tisućinu njegove mase.
02:19
And we call this satellite
"Dove" — Thank you.
"Dove" — Thank you.
43
127387
3753
I zovemo ovaj satelit
"Golubica" — Hvala vam.
"Golubica" — Hvala vam.
02:23
(Applause)
44
131140
2295
(Aplauz)
02:25
We call this satellite "Dove,"
45
133435
2045
Zovemo ovaj satelit "Golubica",
02:27
and we call it "Dove" because
satellites are typically named
satellites are typically named
46
135480
3019
a zovemo ga "Golubica" jer
sateliti tipično dobijaju imena
sateliti tipično dobijaju imena
02:30
after birds, but normally birds of prey:
47
138499
2366
po pticama, ali
normalno po grabljivicama:
normalno po grabljivicama:
02:32
like Eagle, Hawk, Swoop,
Kill, I don't know,
Kill, I don't know,
48
140865
2837
kao Orao, Jastreb,
Sokol, Škanjac, ne znam,
Sokol, Škanjac, ne znam,
02:35
Kestrel, these sort of things.
49
143702
1715
Kliktavac, ta vrsta stvari.
02:37
But ours have a
humanitarian mission,

50
145417
1925
Ali naši imaju
humanitarnu misiju,
humanitarnu misiju,
02:39
so we wanted to call them Doves.
51
147342
1833
pa smo ih željeli nazvati Golubice.
02:41
And we haven't just
built them, though.
built them, though.
52
149175
1934
I nismo ih samo sagradili.
02:43
We've launched them.
53
151109
1341
Lansirali smo ih.
02:44
And not just one, but many.
54
152450
3118
I ne samo jednog, već puno.
02:50
It all started in our garage.
55
158586
2367
Sve je počelo u našoj garaži.
02:52
Yes, we built our first satellite
prototype in our garage.

56
160953
2814
Da, naš prvi prototip satelita
sagradili smo u našoj garaži.
sagradili smo u našoj garaži.
02:55
Now, this is pretty normal for a
Silicon Valley company that we are,
Silicon Valley company that we are,
57
163767
3217
Sad, to je poprilično normalno za
kompaniju iz Silicijske doline što i jesmo,
kompaniju iz Silicijske doline što i jesmo,
02:58
but we believe it's the first time
for a space company.
for a space company.
58
166984
2943
Ali vjerujemo da je to prvi put
za svemirsku kompaniju.
za svemirsku kompaniju.
03:01
And that's not the only trick
we learned from Silicon Valley.
we learned from Silicon Valley.
59
169927
3468
A to nije jedini trik
koji smo naučili od Silicijske doline.
koji smo naučili od Silicijske doline.
03:05
We rapidly prototype our satellites.
60
173395
3192
Brzo izrađujemo prototipe naših satelita.
03:08
We use "release early,
release often" on our software.

61
176587
2885
Koristimo "objavi rano,
objavi često" na našem softveru.

03:11
And we take a different
risk approach.
risk approach.
62
179472
1917
I drugačije pristupamo riziku.
03:13
We take them outside and test them.
63
181389
2003
Iznosimo ih van i testiramo ih.
03:15
We even put satellites in space
just to test the satellites,
just to test the satellites,
64
183392
2889
Čak i stavljamo satelite u svemir
samo da testiramo satelite,
samo da testiramo satelite,
03:18
and we've learned to manufacture
our satellites at scale.
our satellites at scale.
65
186281
2863
i naučili smo proizvoditi
naše satelite u mjerilu.
naše satelite u mjerilu.
03:21
We've used modern production techniques
66
189144
2066
Koristili smo moderne tehnike proizvodnje
03:23
so we can build large numbers of them,
67
191210
2713
da bismo ih mogli sagraditi velik broj,
03:25
I think for the first time.
68
193923
2197
mislim po prvi put.
03:28
We call it agile aerospace,
69
196120
3000
Zovemo to okretan zračno-svemirski,
03:31
and that's what's enabled us to put
so much capability into this little box.
so much capability into this little box.
70
199120
5688
i to je ono što nam je omogućilo da
stavimo toliku moć u ovu malu kutiju.
stavimo toliku moć u ovu malu kutiju.
03:36
Now, what has bonded
our team over the years
our team over the years
71
204808
4492
Sad, ono što je povezivalo
naš tim tijekom godina
naš tim tijekom godina
03:41
is the idea of democratizing
access to satellite information.

72
209300
5136
je ideja demokratizacije
pristupa satelitskim informacijama.

03:51
when they were hosting a conference
about exactly that question:
about exactly that question:
75
219526
2985
kada su imali konferenciju
o točno tom pitanju:
o točno tom pitanju:
03:54
How do you use satellites
to help humanity?

Kako koristiti satelite
kao pomoć čovječanstvu?

03:57
or with climate change?
78
225932
2007
ili sa klimatskim promjenama?
03:59
And this is what has bonded us.
79
227939
2466
I to nas je povezalo.
04:02
Our entire team is passionate about
using satellites to help humanity.

04:06
You could say
we're space geeks,
we're space geeks,
81
234970
1777
Možete reći da smo svemirski geekovi,
04:08
but not only do we care
about what's up there,
about what's up there,
82
236747
2537
ali nije samo da nam je
stalo do onog što je gore,
stalo do onog što je gore,
04:11
we care about what's down here, too.
83
239284
2092
stalo nam je i do onog što je dolje.
04:13
I'm going to show you a video
84
241376
1726
Pokazat ću vam snimku
04:15
from just four weeks ago
of two of our satellites

Ovo nije animacija,
04:22
this is a video taken by the astronaut

04:25
It gives you a bit of a sense of
scale of our two satellites.

89
253490
2989
Daje vam malo osjećaja
razmjera naša dva satelita.

04:28
It's like some of the
smallest satellites ever

04:35
It's really cool. Wait for it.
93
263872

Super je. Čekajte na to.
04:38
Boom! Yeah. It's the money shot.
94
266241
3613
Bum! Da. To je pogodak u sridu.
04:41
(Laughter)
95
269854
2010
(Smijeh)
04:43
So we didn't just launch
two of them like this,
two of them like this,
96
271864
3011
Nismo ih lansirali samo
dva kao ovdje,
dva kao ovdje,
04:46
we launched 28 of them.
97
274875
1726
lansirali smo ih 28.
04:48
It's the largest constellation of
Earth-imaging satellites in human history,
Earth-imaging satellites in human history,
98
276601
3613
To je najveći raspored
satelita za snimanje Zemlje u povijesti,
satelita za snimanje Zemlje u povijesti,
04:52
and it's going to provide a
completely radical new data set

99
280214
3249
i podarit će nam
potpuno radikalan novi set podataka

04:55
about our changing planet.
100
283463
2004
o našem mijenjajućem planetu.
04:57
But that's just the beginning.
101
285467
2228
Ali to je samo početak.
04:59
You see, we're going to launch
more than 100 of these satellites
more than 100 of these satellites
102
287695
3082
Vidite, lansirat ćemo
više od 100 ovih satelita
više od 100 ovih satelita
05:02
like these over the
course of the next year.
course of the next year.
103
290777
2254
poput ovih tijekom
slijedeće godine.
slijedeće godine.
05:05
It's going to be the largest constellation
of satellites in human history.

104
293031
3649
To će biti najveći raspored
satelita u ljudskoj povijesti.
satelita u ljudskoj povijesti.
05:08
And this is what it's going to do:
105
296680
1657
A ovo je što će raditi:
05:10
Acting in a single-orbit plane that
stays fixed with respect to the sun,

298337
3559
Djelujući u ravni jedinstvene orbite koja
ostaje nepomična u odnosu na Sunce,
ostaje nepomična u odnosu na Sunce,
05:13
the Earth rotates underneath.
107
301896
1673
Zemlja rotira ispod.
05:15
They're all cameras pointed down,
108
303569
2295
Svi su oni kamere usmjerene dolje,
05:17
and they slowly scan across as
the Earth rotates underneath.
the Earth rotates underneath.
109
305864
2969
i polako skeniraju poprijeko
kako Zemlja rotira ispod.
kako Zemlja rotira ispod.
05:20
The Earth rotates every 24 hours,
110
308833
2124
Zemlja rotira svakih 24 sata,
05:22
so we scan every point on the
planet every 24 hours.
planet every 24 hours.
111
310957
2972
tako da mi skeniramo svaku
točku na planetu svakih 24 sata.
točku na planetu svakih 24 sata.
05:25
It's a line scanner for the planet.
112
313929
2251
To je planetarni linijski skener.
05:28
We don't take a picture of
anywhere on the planet every day,
anywhere on the planet every day,
113
316180
3454
Ne uzimamo snimke
negdje na planeti svaki dan,
negdje na planeti svaki dan,
05:31
we take a picture of every single
place on the planet every day.

114
319634
3186
Uzimamo snimke
svugdje na planeti svaki dan.
svugdje na planeti svaki dan.

The general point is that we will be able
to track urban growth as it happens

kako ima možda vjerojatno
stotine i tisuće primjena ovih podataka,
