ABOUT THE SPEAKER
Moriba Jah - Space environmentalist
TED Fellow Moriba Jah studies and predicts the motion of objects in space in an effort to make space safe, secure, and sustainable.

Why you should listen

All kinds of junk are floating around in space -- old satellites, rockets, other man-made debris -- that pose an increasing danger to space missions. Astrodynamicist Moriba Jah monitors this orbital debris with ASTRIAGraph, a software that tracks the positions and speeds of objects in Earth’s orbit. Jah's vision is for AstriaGraph to become a crowd-sourced citizen-science platform that will make information about space traffic openly available to future generations. His ultimate goal is to make space safe, secure and sustainable.

Moriba Jah: The world's first crowdsourced space traffic monitoring system

Moriba Jah: Prvi skupno financirani sustav praćenja svemirskog prometa na svijetu

"Većina onoga što pošaljemo u svemir se nikada ne vrati", kaže astrodinamičar i TED-ov suradnik Moriba Jah. U ovom nadahnutom govoru Jah opisuje svemirske autoceste koje kruže oko Zemlje i kako su većinom pune svemirskog otpada. Naučimo više o njegovoj misiji da razvije i uputi u masovnu upotrebu prvi skupno financirani sustav praćenja svemirskog prometa na svijetu - i kako bi to moglo riješiti problem otpadnih nakupina u prostoru bliže Zemlji.

00:45
Now these servicesusluge are not protectedzaštićeni

Sve te usluge nisu zaštićene od oko

u doticaju s jednim od ovih objekata
01:04

15
52757
2219
mogla bi ih oštetiti
do stanja neupotrebljivosti.
01:08
But we can't trackstaza things
as smallmali as a specktrun of paintboja.
16
56394
3925
Ali ne možemo pratiti predmete
sićušne poput mrlje boje.
01:12
We can only trackstaza things
as smallmali as say, a smartphonesmartphone.
17
60694
4164
Možemo pratiti samo stvari
veličine, primjerice, mobitela.
01:17
So of this halfpola millionmilijuna objectsobjekti
that we should be concernedzabrinut about,
18
65605
4866
Od tih pola milijuna predmeta
koji bi nas trebali zabrinjavati,
01:22
we can only trackstaza
about 26,000 of these objectsobjekti.
19
70495
4157
možemo pratiti samo oko
26 000 tih predmeta.
01:26
And of these 26,000,
only 2,000 actuallyzapravo work.
20
74676

A od tih 26 000
samo 2000 doista funkcioniraju.

That's a lot of garbagesmeće.
23
86481

To je puno smeća.
01:40
To make things a little bitbit worsegore,
24
88227
1928
Da još pogoršamo situaciju,
01:43
mostnajviše of what we launchlansiranje into orbitorbita
never comesdolazi back.
25
91356
4069
većina toga što pošaljemo u orbitu
nikada se ne vrati.
01:49
We sendposlati the satellitesatelit in orbitorbita,
26

Pošaljemo satelit u orbitu,

it stopszaustavlja workingrad, it runsradi out of fuelgorivo,
27

2968
pokvari se, ostane bez goriva,
01:55
and we sendposlati something elsedrugo up ...
28
103123
2635
a mi pošaljemo gore nešto drugo...
01:57
and then we sendposlati up something elsedrugo ...
29
105782
2365
pa zatim nešto drugo...
02:00
and then something elsedrugo.
30
108171
1491
pa još nešto drugo.
02:01
And everysvaki oncejednom in a while,
31
109686
1529
Prije ili kasnije
02:03
two of these things
will collidesudariti se with eachsvaki other
32
111239
2530
dva takva predmeta se sudare
02:05
or one of these things will explodeeksplodirati,
33
113793
1771
ili jedan od njih eksplodira,
02:07
or even worsegore,
34
115588
1195
ili još gore,
02:08
somebodyneko mightmoć just happendogoditi se to destroyuništiti

35
116807
3685
netko slučajno uništi
svoje satelite u orbiti,
02:13
and this generatesgenerira manymnogi, manymnogi more pieceskomada,
36
121595
3659
što stvara još puno, puno sitnih komada
02:17
mostnajviše of whichkoji alsotakođer never come back.
37
125278
2602
od kojih se većina također nikad ne vrati.
02:20
Now these things are not
just randomlyslučajno scatteredraspršene in orbitorbita.
38
128748
3760
Ti predmeti nisu samo proizvoljno
razbacani po orbiti.
02:25
It turnsokreti out that givendan

Ispostavlja se da, uzmemo li u
obzir prostorno-vremensku strukturu,
02:28
there are idealidealan locationslokacije
40
136984
1962
postoje idealne lokacije
02:30
where we put some of these satellitessateliti --
41
138970
1986
gdje postavljamo satelite --
02:32
think of these as spaceprostor highwaysautoceste.
42
140980
2751
zamislite to kao svemirske autoceste.
02:37
Very much like highwaysautoceste on earthZemlja,
43
145344
1889
Baš poput autocesta na Zemlji,
02:39
these spaceprostor highwaysautoceste can only take up
a maximummaksimum capacitykapacitet of trafficpromet
44
147257
4719
te autoceste mogu primiti
određeni kapacitet prometa
02:44

kako bi funkcionirale na sigurnoj razini.
02:49
UnlikeZa razliku od highwaysautoceste on earthZemlja,
46
157014
2336
Za razliku od autocesta na Zemlji,
02:51
there are actuallyzapravo no spaceprostor trafficpromet rulespravila.
47
159374
2212
svemirska prometna pravila
doslovno ne postoje.
02:53
NoneNiti jedan whatsoevergod, OK?
48
161610
1933
Nikakvih, OK?
02:57
WowSjajna osoba.
49
165662
1150
Wow.
03:00
What could possiblymožda go wrongpogrešno with that?
50
168450
1945
Što bi tu moglo uopće poći po zlu?
03:02
(LaughterSmijeh)
51
170419
1367
(Smijeh)
03:04
Now, what would be really nicelijepo
52
172482
2315
Stoga bi bilo vrlo lijepo
03:06
is if we had something
like a spaceprostor trafficpromet mapkarta,
53
174821
3638
kad bismo imali nešto poput
svemirske karte prometa,
03:10
like a WazeWaze for spaceprostor that I could look up
54
178483
3023
kao Waze aplikacije za svemir,
gdje bih mogao pogledati
03:13
and see what the currentstruja
trafficpromet conditionsUvjeti are in spaceprostor,
55
181530
2767
i vidjeti trenutne prometne
uvjete u svemiru,
03:16
maybe even predictpredvidjeti these.
56
184321
1434
možda ih čak i predvidjeti.
03:17
The problemproblem with that, howevermeđutim,
57
185779
2103
Međutim, problem u tome je
03:19
is that askpitati fivepet differentdrugačiji people,
58
187906
3362
ako pitate petero različitih ljudi,
03:24
"What's going on in orbitorbita?
59
192337
1403
"Što se događa u orbiti?",
03:25
Where are things going?"
60
193764
1215
"Kamo odlaze predmeti?",
03:27
and you're probablyvjerojatno going to get
10 differentdrugačiji answersodgovori.
61
195003
2673
vjerojatno ćete dobiti
10 različitih odgovora.
03:29
Why is that?
62
197700
1382
Zašto?
03:31
It's because informationinformacija about things
on orbitorbita is not commonlyobično sharedpodijeljen eitherili.
63
199106
4810
Zato što podaci o predmetima u orbiti
nisu javno dostupni.
03:37
So what if we had a globallyglobalno accessibledostupan,
64
205187
2495
Što ako bismo imali

03:39
openotvoren and transparenttransparentan

03:46
to try to keep spaceprostor safesef and sustainableodrživ?
67
214117
2980
kako bismo pokušali svemir učiniti
sigurnim i održivim?
03:49
And what if the systemsistem could be used

What if you only had informationinformacija

Što ako podatke dobivate jedino

04:36
