this is your telescope

00:00:10,629 --> 00:00:07,680
an engineering marvel

00:00:13,589 --> 00:00:10,639
an exploration powerhouse

4
00:00:15,749 --> 00:00:13,599
use it to look back in time and explore

5
00:00:17,910 --> 00:00:15,759
the first galaxies that formed after the

00:00:20,070 --> 00:00:17,920
big bang

7
00:00:21,910 --> 00:00:20,080
to peer into atmospheres of planets

00:00:25,109 --> 00:00:21,920
orbiting the stars

00:00:27,170 --> 00:00:25,119
it's your eyepiece to the uncharted

00:00:31,509 --> 00:00:27,180
unknown and unimagined

11
00:00:35,510 --> 00:00:32,389
this

12
00:00:37,750 --> 00:00:35,520
is the largest most complex and

13
00:00:39,030 --> 00:00:37,760
challenging space telescope ever

14
00:00:40,709 --> 00:00:39,040
constructed

15
00:00:43,750 --> 00:00:40,719
it will change our understanding of the

16
00:00:50,900 --> 00:00:43,760
universe and our place in it

00:01:03,029 --> 00:01:00,239
ever to be flown in space at six and a

20
00:01:05,109 --> 00:01:03,039
half meters it's more than six times the

21
00:01:08,710 --> 00:01:05,119
size of the hubble space telescope

00:01:13,990 --> 00:01:11,030
webs four cutting edge infrared

cold temperatures

25
00:01:19,580 --> 00:01:18,159
temperatures colder than the surface of

28
00:01:27,109 --> 00:01:24,240
getting this cold is done with the help

00:01:29,510 --> 00:01:27,119
of the largest sun shield ever flown

30
00:01:31,990 --> 00:01:29,520
a five-layer tennis court-sized sun

00:01:42,789 --> 00:01:40,799
webb will be the first telescope to

00:01:45,270 --> 00:01:42,799
detect light from the most distant

35
00:01:47,749 --> 00:01:45,280
galaxies in the universe

36
00:01:49,910 --> 00:01:47,759
these first galaxies formed about 13 and

37
00:01:52,469 --> 00:01:49,920
a half billion years ago

38
00:01:54,389 --> 00:01:52,479
only 300 or so million years after the

00:01:56,870 --> 00:01:54,399
big bang

40
00:01:58,870 --> 00:01:56,880
webb carries advanced technologies to

41
00:02:01,590 --> 00:01:58,880
tackle some of the most fundamental

42
00:02:03,190 --> 00:02:01,600
questions about the universe

43
00:02:04,469 --> 00:02:03,200
how did the first galaxies form and

44
00:02:06,149 --> 00:02:04,479
evolve

45
00:02:09,109 --> 00:02:06,159
are there chemical signatures of the

46
00:02:15,910 --> 00:02:09,119
building blocks of life on other worlds

47
00:02:19,990 --> 00:02:17,750
launching such a large telescope into

48
00:02:21,350 --> 00:02:20,000
space is an incredible engineering

49
00:02:22,630 --> 00:02:21,360
challenge

rocket fairing

53
00:02:31,830 --> 00:02:28,959
engineers designed it to be folded like

00:02:34,869 --> 00:02:31,840

deploy web remotely

58
00:02:49,750 --> 00:02:47,599
deployment is an intricate ballet
